TIPS FOR PARENTS WITH
EATING DISORDERS By Abigail Natenshon
Disordered parents need to take care of themselves by asking for support from their loved ones, finding professional help for themselves
& getting well. Eating disorders are curable.
When parents proactively address these issues & help themselves,
they're helping & protecting their children at the same time.
The age of the child will play a big part in determining how
a parent should communicate & what he or she might say.
Parents must speak on a childs level & to the childs needs,
creating a forum for discussion that's comfortable, honest & open.
Similarly, such an open forum needs to be created w/ spouse
& w/ therapist.
-
Parents need to dispel their own & their childrens misconceptions
about food & diet, such as . . .eating fat makes a person fat, food is fattening, dieting is the best way to lose weight,
etc.
The media confuses us w/ constant
& conflicting messages about how to eat, stay thin & be successful & loved. It's important to be discerning & savvy in taking in such messages.
-
Having talked the talk, parents
must walk that talk. Parents must not be afraid to remain parental, staying emotionally connected with their children &
setting appropriate & respectful limits, thereby creating a sense of security & safety that precludes the childs need
for an eating disorder to provide internal regulation.
Parents need to model healthy eating,
provide nutritious, balanced & regular meals & eat them together w/ the family as often as possible.
One family members changes can be
facilitated & sustained through parallel changes made by other members of the family system.
In addition, when one partner
in a marriage makes changes independent of spouse or partner, resulting imbalances in the marital system can cause additional
problems.
-
Recognize that eating disorders
are multi-dimensional diseases that are best treated by a team of professionals & loved ones, including medical doctor,
psychopharmacologist & nutritionist, as well as individual & family psychotherapists.
-
Parents with eating disorders must forgive themselves, recognizing that though they have no control over the past, they do have control over their present
attempts to get well & stay well.
-
Parents with eating disorders must learn how to take time out of each day to recognize what they need & to take care of themselves, to feed themselves
both literally & figuratively in every way that they can.
- Most importantly, parents with eating disorders must be aware
that it is not a foregone conclusion that their children will be adversely affected by their problems.
When two parents can be of one mind & present a united front
to child, disease & professional, the strengths of one parent can compensate for the weakness of the other. When parents
face an eating disorder & conquer it openly, inclusive of their spouses & childrens input & understanding, everyone
stands to gain, not only in terms of how they eat, but also in terms of how they face & deal w/ life & the long-term
quality of family relationships.



News from the APA: Men Less Likely
To Seek Help for Eating Disorders
April, 2001 —
Eating disorders, such as anorexia & bulimia, are more common in men than was previously thought, according to a study
published in the April 2001 issue of American Journal of Psychiatry, a journal of the American Psychiatric Association
(APA). The study authors also found that men are not as likely as women to seek treatment for eating disorders.
Bulimia is an eating disorder characterized by binge eating followed by purging or other methods to control weight. Anorexia is characterized by the refusal or inability to maintain normal weight combined with an intense fear of gaining weight.
There has been continued debate
as to whether men with eating disorders suffer from the same mental disorders & symptoms as women with the disorders,
a question fueled by the fact that few men participate in programs that treat eating disorders.
The authors compared 62 men
who met all or most of the "Diagnostic & Statistical Manual of Mental Disorders" criteria for eating disorders with 212
women who had similar eating disorders & with 3,769 men who didn't have eating disorders.
"Men are generally very similar
to women in terms of comparing psychopathology," said lead author D. Blake Woodside, M.D., of the Department of Psychiatry
at Toronto Hospital. "The illnesses are much more equivalent in prevalence than was previously thought. We have to think about why men wouldn't come for treatment."
One possible explanation is
that men are reluctant to come for help because they feel eating disorders fall into the category of "women's diseases." This reason is linked to the second possible reason, which is that men may
not recognize the symptoms of an eating disorder because eating disorders have long been assumed to plague women only. "Men with symptoms should get help, as women do. This is where public education
comes in," Dr. Woodside said, adding that public education efforts should do more to identify & treat men with eating disorders.
Through their comparison of
men with eating disorders to men in the general population, the study authors found that men with eating disorders were more likely to have other mental disorders & were less satisfied with their lives. Dr. Woodside said that these differences could result from side effects of the disorders.



Anorexia Nervosa is a severe,
life-threatening disorder in which the individual refuses to maintain a minimally normal body weight, is intensely afraid of gaining weight & exhibits a significant distortion in the perception of the shape or size of his body, as well as dissatisfaction with his body shape and size.
Behavioral Characteristics:
- Excessive dieting, fasting, restricted diet
- Food rituals
- Preoccupation with body building, weight
lifting, or muscle toning
- Compulsive exercise
- Difficulty eating with others, lying about eating
- Frequently weighing self
- Preoccupation with food
- Focus on certain body parts; e.g., buttocks, thighs, stomach
- Disgust with body size or shape
- Distortion of body size; i.e., feels fat even though others
tell him he is already very thin
Emotional & Mental Characteristics:
- Intense fear of becoming fat or gaining weight
- Depression
- Social isolation
- Strong need to be in control
- Rigid, inflexible thinking, “all or nothing”
- Decreased interest in sex or fears around
sex
- Possible conflict over gender identity or sexual orientation
- Low sense of self worth - uses weight as a measure of worth
- Difficulty expressing feelings
- Perfectionistic - strives to be the neatest, thinnest, smartest,
etc.
- Difficulty thinking clearly or concentrating
- Irritability, denial - believes others are overreacting to
his low weight or caloric restriction
- Insomnia
Physical Characteristics:
- Low body weight (15% or more below what is expected for age,
height, activity level)
- Lack of energy, fatigue
- Muscular weakness
- Decreased balance, unsteady gait
- Lowered body temperature, blood pressure, pulse rate
- Tingling in hands and feet
- Thinning hair or hair loss
- Lanugo (downy growth of body hair)
- Heart arrhythmia
- Lowered testosterone levels



Binge eating disorder is a
severe, life-threatening disorder characterized by recurrent episodes of compulsive overeating or binge eating. In binge eating
disorder, the purging in an attempt to prevent weight gain that is characteristic of bulimia nervosa is absent.
Behavioral Characteristics:
- Recurrent episodes of binge eating
- Eating much more rapidly than normal
- A sense of lack of control over eating during binge episodes
- Eating large amounts of food when not feeling physically hungry
- Hoarding food
- Hiding food and eating in secret; e.g., eating alone or in
the car, hiding wrappers
- Eating until feeling uncomfortably full
- Eating throughout the day with no planned mealtimes
Emotional & Mental Characteristics:
- Feelings of disgust, guilt, or depression during and after
overeating
- Binge eating often triggered by uncomfortable feelings such
as anger, anxiety, or shame
- Binge eating used as a means of relieving tension, or to “numb”
feelings
- Rigid, inflexible “all or nothing” thinking
- Strong need to be in control
- Difficulty expressing feelings and needs
- Perfectionistic
- Works hard to please others
- Avoids conflict, tries to “keep the peace”
- Disgust about body size, often teased about their body while
growing up
- Feelings of worthlessness
- Social isolation
- Depression
- Moodiness and irritability
Physical Characteristics:
- Heart and blood pressure problems
- Joint problems
- Abnormal blood-sugar levels
- Fatigue
- Difficulty walking or engaging in physical activities
Men With Eating Disorders Have Healthy Body "Ideal"
By Amy Norton
NEW YORK (Reuters Health) - Eating disorders in men may be fueled
by a distorted perception of their own bodies, rather than an unhealthy notion of what the "ideal" body is, the results of
a small study suggests.
Researchers found that while men w/anorexia or bulimia saw themselves
as much heavier than they actually were, their idea of an ideal body was no different from that of healthy men their age.
Distorted body image is well known to be at the roots of eating
disorders. But studies have traditionally not distinguished between patients' perceptions of their own bodies & what they
believe to be the ideal body, according to the new study's lead author.
"Our study suggests that the body image distortion in eating
disorders is based primarily on a distorted body perception & not on the body ideals of patients," Dr. Barbara Mangweth
of the University Clinics Innsbruck in Austria told Reuters Health.
This distinction is important, according to Mangweth & her
colleagues, because it could make a difference in treatment. For example, men with eating disorders may not need to be "re-educated"
about healthy body fat levels, they report in the International Journal of Eating Disorders.
Whether the findings might extend to women, who suffer from
eating disorders much more often than men do, is unclear, according to the researchers. However, they point to a recent study
that found normal-weight, dieting women had distorted perceptions of their own bodies, but had body ideals similar to those
of women who were not dieting.
The new study involved 27 men ages 19 to 43 with anorexia or
bulimia & 42 athletic and non-athletic men of the same age. Mangweth's team had the men take a computerized test that
allowed them to "morph" an image of a male body to have various levels of fat & muscle.
Participants had to choose images that best represented their
own bodies, the body they would like to have & the one they thought women would prefer.
The researchers found no differences between the groups when
it came to body fat ideals. However, men with eating disorders saw themselves as twice as fat as they actually were, while
healthy participants showed no such distortion.
The findings, according to Mangweth, suggest that in both research
and therapy, it is important to distinguish patients' beliefs about their bodies from their general body preferences.

The Hunger Artists
Are genes & brain chemistry at the root of eating disorders?
By Emily Sohn
Dinnertime was always stressfulat the Corbett house. Every evening at 6 o'clock precisely,
the 5 kids would take their assigned places at the table between Mom & Dad. Food was served family style, & whatever
you took, you had to eat. You couldn't have dessert until after you had finished everything on your plate.
"It
was not a relaxing time to sit at the table & eat," recalls Cathie Reinard, 35, about her childhood in Rochester,
N.Y. But the "rigid rules just added to an underlying tension." As the kids got older, it became clear that most meals would end with Mom's excusing herself,
going into the bathroom, &making herself throw up.
Dysfunctional families are
still a common target of blame, as is a dysfunctional culture obsessed w/thinness. But as doctors learn more about eating disorders, it is becoming clear that genetics
& biology may be equally important causal factors for the estimated 5 million to 10 million Americans who struggle w/anorexia,
bulimia & binge-eating disorders.
Although family & culture may provide the ultimate trigger,
it seems increasingly likely that hormones & brain chemicals prime a certain group of people to push themselves to starvation.
The hidden killer.
Eating
disorders are the deadliest of all psychiatric disorders, killing or contributing to the deaths of thousands every year. An
estimated 50,000 people currently suffering from an eating disorder will eventually die as a result of it.
Anorexics, who pursue thinness so relentlessly through diet
& exercise that they drop to below 85% of ideal body weight, often suffer heart attacks, arthritis, osteoporosis &
other health problems. Bulimics eat uncontrollably, then compensate by throwing up, taking laxatives, or exercising obsessively
- behaviors that can upset the body's chemical balance enough that it stops working.
As w/depression & other
serious psychiatric illnesses, eating disorders now appear to be a familial curse. Relatives of eating disorder patients are
7 to 12 times as likely to develop an eating disorder as is the general population, studies show. Depression, anxiety disorders,
& other related illnesses also appear more frequently in the same families. That doesn't rule out a shared environment
as a contributing factor, says psychologist Michael Strober of the University of California - Los Angeles. But, he adds, "anytime you see a disorder that runs in families, you begin to suspect
some hereditary influence."
The women in Bailey's family have been fighting a losing battle
with food for generations. When Bailey was 18, her 55 pound mother starved herself to death, sneaking laxatives in the hospital
until the very end. Other relatives have also suffered from anorexia. "I was always told I was fat and ugly & dumb," recalls
Bailey, a 63-year-old retired nurse. She vividly remembers how she & her brothers secreted cans of food because they weren't
getting enough to eat at meals. But, she concedes now, the sheer number of eating disorders in her family suggests something
deeper going on.
Deadly eating disorders exist in cultures far removed from Hollywood
& Madison Avenue & have been around far longer than glossy women's magazines. But if that weren't evidence enough
for an underlying biology, the patients themselves are the first to say their eating disorders have a power far greater than
peer pressure.
Indeed, Stephanie Rose's illness had such a strong "personality"
that she named it "Ed." It started with a diet to lose 8 pounds of weight gain after her freshman year of college. But her
success became an obsession that landed her in the hospital 9 times over the next 4 years. She crashed a car & a bicycle,
both times after passing out from nutrient deprivation. She chugged bottles of poison-control syrup to make herself throw
up, even if she had eaten only a bite of a tuna fish sandwich or a few grains of cereal. Even in the hospital, she shoved
batteries in her underwear to fool the nurses when they weighed her. Talking & reading took too much energy, so she stared
at the TV instead, gray-skinned, too weak to think.
At her sickest, the 5'5" Needham, Mass., resident weighed
75 pounds. She had a mild heart attack at age 21 as
a result of her starved state. Doctors told her bluntly that she was going to die & nurses sat w/her 24 hours a day to
make sure she didn't pull out her feeding tube. Now 29, fully recovered & happily married with a 15 month-old baby of
her own, Rose can't believe she would flirt w/death for arms that looked like toothpicks. "It was like someone took over my
body," she says, "this guy, Ed."
The most convincing evidence for genetics comes from twins.
If one twin has an eating disorder, the other is far more likely to have a similar illness if the twins are identical rather
than fraternal. Since identical twins are genetic clones of each other, that is powerful evidence that genes play an important
role, says psychiatrist Cynthia Bulik of Virginia Commonwealth University: "Until now, people would have said there wasn't
a genetic effect in anorexia. And what we're saying is that there really is, & it's not minimal."
Gene hunt.
Several groups of researchers
are now hunting for the specific genes involved in eating disorders, w/some promising leads. The first 2 comprehensive scans
of the human genome have recently turned up hot spots for anorexia-linked genes on several chromosomes, including Chromosome
1, which seems to harbor genes for the most severe form of anorexia. "We now know the location of several genes in the human
genome which increase risk for anorexia nervosa," says University of Pennsylvania psychiatrist Wade Berrettini, a senior author
of a study in the March issue of the American Journal of Human Genetics. "Prior to this, we did not." Other preliminary
work is pointing to different areas of the genome that may be involved in bulimia, says psychiatrist Walter Kaye of the University
of Pittsburgh.
None of the scientists exploring the genome expects to find
easy answers or simple genetic switches. Indeed, hundreds of genes are already known to influence appetite and eating regulation
in some way, a testament to how complex the eating impulse really is in the grand scheme of human biology.
But some patterns are emerging. The most obvious is that 90%
of eating disorders occur in girls & women, most often beginning in adolescence.
This clue has some experts exploring the genes that control
hormone production. During the teen years in most girls, estrogen-producing genes kick in, triggering puberty. And there is
evidence, says Michigan State psychologist Kelly Klump, suggesting that those genes may also contribute to eating disorders
in some girls: Genes appear to be involved in 17-year-old twins with eating disorders but not in 11-year-old twins, who are
mostly prepubescent. But even more striking, Klump says, a recent study of 11-year-old twins who had gone through puberty
and exhibited warning signs of the illness showed the same genetic pattern as the 17-year-olds. Klump notes, by analogy, that
depression hits girls twice as hard after puberty as before.
Other researchers are linking eating
disorders to personality traits that are hard-wired into the brain. Anorexics tend to be Type A - anxious, perfectionist, rigid. Those
traits can translate into an unhealthy body image: When a driven perfectionist sets her mind on being slender, self-control
can become a measure of success. Anorexics also tend to be ritualistic about the food they eat, cutting it into tiny pieces
or eating only a specific type of food at only a specific time of day.
Obsessed.
Such an obsessive temperament often appears to be inborn. In Kathryn Carvette DeVito's case, the first signs
appeared at age 7. She started having panic attacks
on the school playground & became preoccupied w/getting her homework perfect, starting over & over again if necessary.
Then she developed some classic symptoms of obsessive-compulsive disorder: "If I touched a doorknob 15 times,
everything would be OK," she says. Kathryn hit puberty
earlier than her classmates & when a doctor told her she was heavier than the average 6th grader, her ob- sessions turned
to food. She dropped to a low of 85 pounds before seeking help when she was 19. Even now, though the 5'foot 2" Boston University
senior sees a psychologist weekly & has stabilized her weight at about 100 pounds, she says that she sometimes eats as
little as 100 calories a day. She works out every day & does sit-ups in her bed at night.
Brain chemicals may contribute to illnesses such as Kathryn's, says the University of Pittsburgh's Kaye. It may be that people
who go on to develop the anxiety & obsessiveness associated w/eating disorders have abnormally high levels of serotonin,
one of the brain's major chemical messengers for mood, sexual desire, & food intake. Losing weight lowers serotonin, so
anorexics may stop eating in a subconscious attempt to lower their uncomfortably high serotonin levels, says psychiatrist
Evelyn Attia of the New York State Psychiatric Institute. But when a person stops eating, her brain churns out even more serotonin,
Attia says. So, the anorexic gets caught "in a vicious cycle where the behavior tries to compensate for the uncomfortable
feeling of biochemical imbalance but can never catch up."
Kaye also has evidence that the brains of recovered
bulimics process serotonin in a way that is different from the brains of healthy people. It's not entirely clear yet if their brains were different before they developed the
disease or if dieting caused the changes. Still, such chemi-cal differences suggest that drugs like Prozac, used to treat
depression & compulsive behaviors, might be helpful for treating eating disorders as well. In a small study, Kaye found
that Prozac, which helps the brain's pathways work better, helped prevent relapses in recovered anorexics.
Despite all these biomedical advances in understanding
eating disorders, victims still face a long & uncertain road to recovery. Only about 1/2 of anorexics & bulimics ever
recover enough to maintain a healthy weight & positive self-image. 30% of anorexics have residual symptoms that persist
long into adulthood & 1 in 10 cases remains chronic & unremitting. Without treatment, up to 20% of cases end in premature
death.
Denial & resistance to treatment are fierce psychological
obstacles once an eating disorder has taken hold, so scientists
are looking more & more to prevention. & ironically, given the move away from cultural explanations for the disorders,
the best interventions for now may still be psychosocial. Surveys show that 42% of children in 1st through 3rd grade want
to be thinner & that 81% of 10-year-olds are afraid of being fat. Those attitudes are clearly not genetic & they are
so pervasive that they could be pushing the genetically vulnerable over the edge. "If people never diet," Bulik says, "they
might never enter into the higher-risk category for developing eating disorders."
One of the most striking examples of culture's influence comes
from Fiji, where a bulky body has always been a beautiful body. Women on the South Pacific island have traditionally complimented
one another for gaining weight. Food is starchy, calorie-dense & plentiful. But when TV came to the island in 1995 w/shows
like Melrose Place & commercials celebrating thinnessthe depictions of beauty radically altered Fijians' self-imageespecially
the girls'. According to a study published this month by Harvard psychiatrist & anthropologist Anne Becker, by 1998 the
proportion of girls at risk for developing eating disorders more than doubled to 29% of the population. The percentage of
girls who vomited to lose weight jumped from 0 to 11%. "We actually talked to girls who explicitly said, 'I want to be thin
because I watch TV, & everyone on TV has all those things, & they're thin,' " Becker says. Likewise, non-Western immigrants
to the US are more likely to develop eating disorders than are their relatives in the homeland.
Cost of starvation. While scientists debate
& explore the causes of eating disorders, victims & their families are being hard hit financially. Hospitalization
& around-the-clock care to revive a starving patient can cost more than $1,000 a day. Full recovery can take years of
therapy, often involving the whole family. But because eating disorders are classified as a mental illness, insurance plans
rarely cover the full costs of treatment. Kitty Westin slammed into just that painful wall. Her daughter Anna had struggled
w/anorexia as a teenager but seemed healthy when she came home to Chaska, Minn., after her sophomore year at the University
of Oregon in Eugene. Within months, depression & anxiety again consumed Anna. She couldn't sleep. She withdrew from her
family & friends. She stopped eating & spent hours at the gym every day. By summer's end, Anna, who had always been
petite, could barely stand without feeling dizzy. At 5' 4", she weighed 82 pounds & her vital signs were dangerously low.
No matter how hard she fought the anorexia, she felt powerless. "It won't leave me alone," she told her mother.
For the next six months, Anna checked in & out of the hospital.
She would improve as an inpatient. But as soon as she went home, she'd get sick again, says Kitty Westin, who quit her job
as a psychologist to take care of her daughter. The family's health insurance company, Blue Cross & Blue Shield of Minnesota,
refused to fully cover the costs of residential treatment, leaving the family to pay for whatever they could. On Feb. 17,
2000, worn out from her struggle, Anna killed herself. She was 21. Her mother, now a full-time advocate for better insurance
coverage, says the family's battles with the insurance company exacerbated Anna's illness. "See, I'm not sick," Anna would
say. "The insurance company says I'm not sick."
Such attitudes are slowly changing. In June 2001, the state
of Minnesota settled a lawsuit against Blue Cross for repeatedly denying coverage to children w/mental health problems. The
settlement required the company to pay the state $8.2 million for treating families that had been refused coverage. The company
is also becoming more accountable to eating disorder patients via an appointed, independent 3 member panel that must review
mental health appeals soon after receiving them. Westin is convinced that such a process would have saved Anna's life. "There
is no doubt in my mind," she says, "that a panel would have reversed the [insurance company's] decision."
A legal acknowledgment that eating disorders are real medical
illnesses brings hope to families who already know that their problems won't just go away. The grown Corbett women, for example,
all still struggle w/body image & health problems related to their eating disorders. Their mother, Margery, was hospitalized
recently for dehydration from drinking too much alcohol & not eating enough. Liz sometimes freezes at the thought of going
out to parties because she can't figure out what to wear. Cathie, who has a 3-year-old daughter & a 9-month-old son, purged
during her 2nd pregnancy & has damaged the enamel surface of her teeth from years of bulimia. Meanwhile, Bonnie continues
to struggle w/anorexia, 17 years after it began. She takes vitamins & mineral supplements to avoid anemia. She takes birth
control pills to keep her hormone levels up. And she has recently started taking medicine to treat end-stage osteoporosis.
At 35, she has the bones of an 86-year-old woman & says her hips would probably shatter if she fell. The whole family
takes things one day at a time. "You get the cards you're dealt," says younger brother Rick, 31, the only sibling spared by
the illness. Instead of cancer or heart disease, he says, his family got eating disorders. "Everyone has their own battles
to fight," Bonnie adds. "This is ours."
Stress Hormones Drive Night Eaters
By Michael Smith,MD - WebMD Medical News Archive Reviewed
By Gary Vogin,MD Feb. 12, 2002
Find yourself raiding the refrigerator in the middle of the night? Turns out that
it may be your body's response to stress that has gone awry, compelling you to eat when you're not even really hungry.
It's not exactly clear how many people have night eating syndrome.
Estimates are around 1%-2% of adults, but some have suggested up to a 1/4 of people who are overweight by at least 100 pounds
eat this way.
Night eaters typically have little or no appetite for breakfast.
They eat more than 1/2 of their daily food after dinner but before breakfast & are often upset about how much was eaten
the night before.
Night eaters feel tense, anxious, upset, or guilty while eating
& at night. They have trouble falling asleep or staying asleep & often wake frequently to eat. Night-eating syndrome
involves continual eating throughout evening hours. This eating produces guilt & shame, not enjoyment.
Night eating syndrome is currently not an official eating disorder.
Previous research has indicated that it may be related to a disruption in your body's 24-hour clock, called the circadian
rhythm.
Another main regulator in your body is a hormone system
called the HPA axis, which also coordinates many of your body's functions, including its response to stress. The association
between these 2 systems is not well understood, so researchers wanted to see if a problem w/the HPA axis might also be behind
night eating syndrome.
Lead researchers Grethe S. Birketvedt & colleagues studied
5 women w/night eating syndrome. The women consumed over 50% of their daily food after 8 p.m. & woke up at least once
during the night to eat. Their hormone levels produced by the HPA axis were compared to women who weren't night eaters.
The study results are featured in the February issue of American
Journal of Physiology - Endocrinology & Metabolism.
During the 7 day study, the women identified as night eaters
woke up more than 3 times per night, on average. The comparison group did not wake up at night to eat.
During the study, all of the women were given a hormone to stimulate
their HPA axis. But in the night eaters, their cortisol levels didn't go as much as the comparison group.
The results suggest that night eaters have an abnormal stress
response caused by a hormone abnormality in their HPA axis, according to the researchers.
Plus, they say that the altered sleep & appetite pattern
may be explained by this abnormal hormone response. Several other eating disorders, such as obesity, anorexia, & bulimia,
have also been linked to abnormalities in the HPA axis.

Nicotine & the Brain Your brain is the key player in nicotine's action. Like a computer, your
brain processes, stores & uses information. In a computer, information travels in the form of electricity moving through
wires; information transfer is a binary process, w/ switches being either "on" or "off." In your brain, neurons are
the cells that transfer & integrate information.
Each neuron has thousands of inputs from other neurons throughout
the brain. Each of these signals is included in the calculation of whether or not the neuron will pass the signal it receives
on to other neurons in the pathway.


A synapse is the site where two neurons come
into contact. The presynaptic neuron releases a neurotransmitter, which binds to receptors on the postsynaptic cell. This
allows signals to be transmitted from neuron to neuron in the brain.
While signals are conducted through individual neurons as electric
current, communication between neurons is mediated by chemical messengers, called neurotransmitters.
Neurotransmitters traverse the physical space between two neurons
& bind to special protein receptors on the postsynaptic cell. Once bound, these receptors set in motion physiological
changes within the neuron that allow it to send the signal on down the line.
Each neurotransmitter has its own specific family of receptors.
Nicotine works by docking to a subset of receptors that bind the neurotransmitter acetylcholine. Acetylcholine is the
neurotransmitter that (depending on what region of the brain a neuron is in):
- Delivers signals from your brain to your muscles
- Controls basic functions like your energy level, the beating
of your heart & how you breathe
- Acts as a "traffic cop" overseeing the flow of information
in your brain
- Plays a role in learning & memory

Acetylcholine is released
from one neuron & binds to receptors on adjacent neurons.
Like acetylcholine, nicotine leads to a burst of receptor activity.
However, unlike acetylcholine, nicotine is not regulated by your body. While neurons typically release small amounts of acetylcholine
in a regulated manner, nicotine activates cholinergic neurons (which mainly use acetylcholine to communicate to other neurons)
in many different regions throughout your brain simultaneously. This stimulation leads to:
- Increased release of acetylcholine from the neurons,
leading to heightened activity in cholinergic pathways throughout your brain. This cholinergic activity calls your body &
brain to action & this is the wake-up call that many smokers use to re-energize themselves throughout the day. Through
these pathways, nicotine improves your reaction time & your ability to pay attention, making you feel like you can work
better.
- Stimulation of cholinergic neurons promotes the
release of the neurotransmitter dopamine in the reward pathways of your brain. This neural circuitry is supposed to
reinforce behaviors that are essential to your survival, like eating when you're hungry. Stimulating neurons in these areas
of the brain brings on pleasant, happy feelings that encourage you to do these things again & again. When drugs like cocaine
or nicotine activate the reward pathways, it reinforces your desire to use them again because you feel so at peace & happy
afterwards.
- Release of glutamate, a neurotransmitter involved
in learning & memory - Glutamate enhances the connections between sets of neurons. These stronger connections may be the
physical basis of what we know as memory. When you use nicotine, glutamate may create a memory loop of the good feelings
you get & further drive the desire to use nicotine.
Nicotine also increases the level of other neurotransmitters
& chemicals that modulate how your brain works. For example, your brain makes more endorphins in response to nicotine.
Endorphins are small proteins that are often called the body's
natural pain killer. It turns out that the chemical structure of endorphins is very similar to that of heavy-duty synthetic
painkillers like morphine.
Endorphins can lead to feelings of euphoria also. If you're
familiar w/ the runner's high that kicks in during a rigorous race, you've experienced the "endorphin rush."
This outpouring of chemicals gives you a mental edge to finish
the race while temporarily masking the nagging pains you might otherwise feel.
Nicotine's Dark Side Some of nicotine's effects have spurred studies on whether it might be
useful as a therapy for certain conditions. Some diseases that nicotine might improve include:
- Alzheimer's Disease - The first neurons lost to
Alzheimers are cholinergic neurons in a specific region of the brain. Nicotine may improve the function of the neurons that
are left & slow the onset of symptoms.
- Tourette's Syndrome - This disease produces tics
(uncontrolled movements of the head, hands & other body parts) & violent urges in its sufferers. Nicotine patches
that slowly deliver nicotine through the skin can reduce symptoms of people w/ Tourette's.
For the average person, the health problems associated w/ using nicotine-containing
products are far worse than any benefits. These include:
- Cancer
- Emphysema
- Heart disease
- Stroke
Many of these are actually caused by other chemicals in cigarette
smoke or in smokeless tobacco products. The biggest problem w/ nicotine is how easily you become dependent on smoking or chewing
tobacco.
Addiction & Withdrawal Billions of dollars have been spent in the US fighting over whether or
not nicotine is addictive. The position of the medical & scientific communities is that nicotine is most definitely
addictive. Nicotine meets both the psychological & physiological measures of addiction:
- Psychological - People who are addicted to something
will use it compulsively, w/out regard for its negative effects on their health or their life. A good example would be someone
who continues to smoke, even as they use an oxygen tank to breathe because of the damage smoking has done to their lungs.
- Physiological - Neuroscientists call anything
that turns on the reward pathway in the brain addictive. Because stimulating this neural circuitry makes you feel so good,
you will continue to do it again & again to get those feelings back.
Nicotine's effects are short-lived, lasting only 40 minutes
to a couple of hours. This leads people to smoke or chew tobacco periodically throughout the day to dose themselves w/ nicotine.
Add to this the fact that you can become tolerant to
nicotine's effects, you need to use more & more nicotine to reach the same degree of stimulation
or relaxation & you can see how people would quickly move from smoking one cigarette to a pack a day habit.
What happens when smokers abruptly stop using nicotine? While
you're using nicotine-containing products, your body adapts the way it works to compensate for the effects of the nicotine.
i.e., neurons in your brain might increase or decrease the number
of receptors or the amount of different neurotransmitters affected by the presence of nicotine. When you no longer have nicotine
in your body, these physiological adaptations for nicotine remain. The net result is that your body can't function the same
way in the absence of the drug as it did before, at least in the short term.
People trying to quit nicotine experience this as:
- Irritability
- Anxiety
- Depression
- Craving for nicotine
Over a period of about a month, these symptoms & the physiological
changes subside. But for many smokers, even a day w/out nicotine is excruciating.
Every year, millions of people try to break the nicotine habit;
only 10% of them succeed. Most people throw in the towel after less than a week of trying, because the way that nicotine rewires the reward system in the brain makes nicotine's pull irresistible.
Toxicity Anti-smoking advocates highlight the long-term health effects, like cancer & emphysema,
that result from a lifetime of smoking or chewing tobacco, but these maladies are the result of chemicals in cigarettes
other than nicotine.
Unfortunately, the fact that nicotine alone is an extremely
toxic poison often goes unmentioned. Not many people realize that nicotine is also sold commercially in the form of a pesticide! Every
year, many children go to the emergency room after eating cigarettes or cigarette butts.
60 milligrams of nicotine (about the amount in 3 or 4 cigarettes
if all of the nicotine were absorbed) will kill an adult, but consuming only one cigarette's worth of nicotine is enough to
make a toddler severely ill!
What happens to people after ingesting nicotine? Nicotine
poisoning causes:
- vomiting
- nausea
- headaches
- difficulty breathing
- stomach pains
- seizures
Each of these symptoms can be traced back to excessive stimulation
