Eating Disorders
Two of the most serious medical problems affecting teenage girls in America are Anorexia Nervosa and Bulimia Nervosa. Both diseases are life- threatening and a shocking 20% of females ages 12- 30 battle one or both of them (the U.S. has the highest rate of eating disorders around the world). Young women with eating disorders suffer from a distorted image of their body, a desire to lose weight, and an obsession with weight. Although eating disorders can affect any age they occur most frequently in teenage girls, where the pressure to be thin and pretty is the strongest. Despite extensive research on eating disorders no one is certain what causes them and how they can be treated most effectively. For some, an eating disorder is a way of coping with stress, low self- esteem, depression, changes of puberty, or family problems. For others it is simply a matter of wanting to lose weight to fit the unhealthy image of models and celebrities. The media is a major contributor to the pressure put on teen girls to be thin, and therefore pretty. Not only is this an incorrect image but also a very dangerous one. All eating disorders need medical attention immediately. Recovery usually includes nutritional and psychological counseling, and extreme cases hospitalization. If necessary steps are not taken to stop the eating disorder permanent damage may result or even death, not to mention the emotional effects. Therefore, if you think you have an eating disorder talk to a person you trust. You will not be alone in your recovery, there are hundreds of doctors and friends to help you. Anorexia Nervosa Victims of Anorexia nervosa restrict their food intake to a dangerously low amount of calories and fat grams. They lose an extreme amount of weight in a short period of time yet they always see themselves as fat. Some girls with anorexia purge (forcefully throw- up food) or use diuretics, laxatives, and diet pills. Anorexia is an extremely dangerous disorder which requires immediate attention. Warning signs of anorexia: Significant weight loss Loss of muscle tissue and body fat Loss of hair on head Growth of fine, fuzzy body hair Absence of menstrual period (amenorrhea) Dry, scaly skin Sensitivity to cold temperatures Difficulty sleeping Fatigue or dizziness Abdominal bloating Constipation Dental problems Low blood pressure, slower pulse Muscle cramps and/ or tremors Behavioral effects: Strict dieting, fasting, or refusal to eat except for small amounts of low- calorie foods Distorted body image Low self- esteem Abnormal fear of gaining weight Unnatural preoccupation with calories, fat, food Ritualistic eating habits, such as cutting up food into small pieces or chewing a certain number of times Withdrawal from family, friends, social activities Cooking and baking for others while not eating food Exercising too much perfectionism These are a few of the long- term effects of prolonged anorexia. These symptoms can be prevented by seeing an eating disorder specialist. A weakened heart due to loss of heart muscle Decreased rate of metabolism Liver and kidney damage Brittle bones Dehydration Death (up to 20% of anorexics die from the disorder) Bulimia People with Bulimia nervosa eat large amounts of food uncontrollably (binge) and then purge to get it out of their system. The binges are usually a result of hunger from dieting. But despite the purging, bulimics often gain weight because not all calories can be thrown up. Like anorexia, bulimia is a very serious medical and psychological problem and must be dealt with immediately to minimize long- term damage. Warning signs of bulimia include: Weight fluctuations due to episodes of bingeing and purging Puffy face Broken blood vessels in face Vomiting of blood Blurred vision Severe tooth damage Sore throat Dependency on laxatives/ diuretics Irregular or no periods Heartburn, indigestion, stomach cramps, bloating, gas, constipation Behavioral effects: Throwing up after meals Bingeing on large amounts of food in short periods of time (usually about 2,000+ calories at once) Sneaking or hiding food to binge on later Feeling guilty about eating large amounts of food Low self- esteem Abnormal concern about weight and body shape Fear of not being able to stop bingeing and purging Fasting or dieting between binges Exercising compulsively to burn calories from binge Depression, mood swings, isolation, suicide attempts Severe effects include: Electrolyte (sodium, potassium) imbalance which can lead to heart failure and dehydration Internal bleeding Liver and kidney damage Death Another eating disorder, compulsive overeating disorder, is characterized by consuming large amounts of food but not purging to control weight. This results in obesity. Characteristics include: Overeating Gains weight Diets to lose weight Feels miserable while dieting Breaks the diet, then feels guilty Finds temporary comfort in eating Gains back weight Diets again If you or someone you know suffers from one of these
problems you must seek help now. Please contact the National Eating Disorders Association at 1-800-931-2237.
Obesity
Obesity is an excess of body fat, which may cause
significant health risks. It results when the number
and size of fat cells in the body increase. However,
when an obese person begins to lose weight the number
of fat cells stays the same, only the size decreases.
This explains why it is difficult to lose a
significant amount of weight once it has been gained.
There are many causes for obesity, including
heredity, diet, age, gender, activity level, etc.
However, one thing is certain: obesity results when
there is an imbalance between energy consumption and
energy expenditure. This means that more calories are
consumed than burned. The extra calories are turned
into fat and are very hard to burn.
To determine obesity, height to weight charts are
often used. These charts were developed by life
insurance companies by determining peoples average
heights and weights. This is a simple, yet not always
precise, method to determine obesity: Females: Take 105 lbs. for 5 0 and add 5 pounds for
every inch. For example, the ideal weight of a 53
woman would be 120 lbs. (105 lbs.+5+5+5). Males: Take 106 lbs. for 5 0 and add 6 pounds for
every additional inch. For example, the ideal weight
of a 5 5 man would be 136 lbs. (106 lbs. + 30). It
is important to understand that there are large ranges
for healthy, ideal weights. For example, a 5 0 woman
can range in weight anywhere from 104 lbs. to 115 lbs.
and still be considered at a healthy weight. The
following are tables for healthy weight.
Height and Weight Chart for Females
Another way of measuring obesity is by determining
the BMI (body mass index). This measurement is more
accurate compared to the weight- height relationship.
The BMI is calculated as follows:
Weight (kg.) / Height (in meters) squared (Ht. X Ht.)
A normal BMI is about 22 to 23. A BMI greater than 25
is considered overweight and a BMI greater than 30 is
considered obese (World Health Organization
Criterion). The long- term goal for obesity is to
achieve a BMI of 30 or a BMI reduction of 5. However,
this decrease in BMI may lead to metabolic
complications (e.g.- hypertension, diabetes). It is
very important to address the problem of obesity in
young children. The older an obese child gets, the
more likely he will become an obese adult.
In the U.S., the amount of population which is obese
or overweight has increased dramatically in the past
20 years. For men, 59% are overweight while 20% are
obese. For women, 51% are overweight and 25% are
obese. These shocking statistics are giving America a
message that eating habits, nutritional value, and
exercise routine of the general population must be
altered. Because if not, the percentage of obesity
will increase, causing America to be at risk for more
and more diseases. |
