Anorexia Nervosa
Anorexia is an eating disorder, marked by an extreme fear of becoming overweight, that leads to excessive dieting to the point of serious ill-health and sometimes death.
Symptoms
- Inadequate food intake leading to a weight that is clearly too low.
- Intense fear of weight gain, obsession with weight and persistent behavior to prevent weight gain.
- Self-esteem overly related to body image.
- Inability to appreciate the severity of the situation.
- Binge-Eating/Purging Type involves binge eating and/or purging behaviors during the last three months.
- Restricting Type does not involve binge eating or purging.
Warning Signs
- Dramatic weight loss.
- Preoccupation with weight, food, calories, fat grams, and dieting.
- Refusal to eat certain foods, progressing to restrictions against whole categories of food (e.g. no carbohydrates, etc.).
- Frequent comments about feeling “fat” or overweight despite weight loss.
- Anxiety about gaining weight or being “fat.”
- Denial of hunger.
- Development of food rituals (e.g. eating foods in certain orders, excessive chewing, rearranging food on a plate).
- Consistent excuses to avoid mealtimes or situations involving food.
- Excessive, rigid exercise regimen–despite weather, fatigue, illness, or injury, the need to “burn off” calories taken in.
- Withdrawal from usual friends and activities.
- In general, behaviors and attitudes indicating that weight loss, dieting, and control of food are becoming primary concerns.
Health Consequences of Anorexia Nervosa
Anorexia nervosa involves self-starvation.; The body is denied the essential nutrients it needs to function normally, so it is forced to slow down all of its processes to conserve energy. This “slowing down” can have serious medical consequences:
- Abnormally slow heart rate and low blood pressure, which mean that the heart muscle is changing. The risk for heart failure rises as heart rate and blood pressure levels sink lower and lower.
- Reduction of bone density (osteoporosis), which results in dry, brittle bones.
- Muscle loss and weakness.
- Severe dehydration, which can result in kidney failure.
- Fainting, fatigue, and overall weakness.
- Dry hair and skin, hair loss is common.
- Growth of a downy layer of hair called lanugo all over the body, including the face, in an effort to keep the body warm.
Bulimia Nervosa
Bulimia nervosa is a serious, potentially life-threatening eating disorder characterized by a cycle of bingeing and compensatory behaviors such as self-induced vomiting designed to undo or compensate for the effects of binge eating.
Symptoms
- Frequent episodes of consuming very large amount of food followed by behaviors to prevent weight gain, such as self-induced vomiting.
- A feeling of being out of control during the binge-eating episodes.
- Self-esteem overly related to body image.
The chance for recovery increases the earlier bulimia nervosa is detected. Therefore, it is important to be aware of some of the warning signs of bulimia nervosa.
Warning Signs of Bulimia Nervosa
- Evidence of binge eating, including disappearance of large amounts of food in short periods of time or finding wrappers and containers indicating the consumption of large amounts of food.
- Evidence of purging behaviors, including frequent trips to the bathroom after meals, signs and/or smells of vomiting, presence of wrappers or packages of laxatives or diuretics.
- Excessive, rigid exercise regimen–despite weather, fatigue, illness, or injury, the compulsive need to “burn off” calories taken in.
- Unusual swelling of the cheeks or jaw area.
- Calluses on the back of the hands and knuckles from self-induced vomiting.
- Discoloration or staining of the teeth.
- Creation of lifestyle schedules or rituals to make time for binge-and-purge sessions.
- Withdrawal from usual friends and activities.
- In general, behaviors and attitudes indicating that weight loss, dieting, and control of food are becoming primary concerns.
- Continued exercise despite injury; overuse injuries.
Health Consequences of Bulimia Nervosa
Bulimia nervosa can be extremely harmful to the body. The recurrent binge-and-purge cycles can damage the entire digestive system and purging behaviors can lead to electrolyte and chemical imbalances in the body that affect the heart and other major organ functions. Some of the health consequences of bulimia nervosa include:
- Electrolyte imbalances that can lead to irregular heartbeats and possibly heart failure and death. Electrolyte imbalance is caused by dehydration and loss of potassium and sodium from the body as a result of purging behaviors.
- Inflammation and possible rupture of the esophagus from frequent vomiting.
- Tooth decay and staining from stomach acids released during frequent vomiting.
- Chronic irregular bowel movements and constipation as a result of laxative abuse.
- Gastric rupture is an uncommon but possible side effect of binge eating.
Binge Eating Disorder
Binge Eating Disorder (BED) is a type of eating disorder that is characterized by recurrent binge eating without the regular use of compensatory measures to counter the binge eating.
Symptoms
- Frequent episodes of consuming very large amount of food but without behaviors to prevent weight gain, such as self-induced vomiting.
- A feeling of being out of control during the binge eating episodes.
- Feelings of strong shame or guilt regarding the binge eating.
- Indications that the binge eating is out of control, such as eating when not hungry, eating to the point of discomfort, or eating alone because of shame about the behavior.
Health Consequences of Binge Eating Disorder
The health risks of BED are most commonly those associated with clinical obesity. Some of the potential health consequences of binge eating disorder include:
- High blood pressure
- High cholesterol levels
- Heart disease
- Diabetes mellitus
- Gallbladder disease
- Musculoskeletal problems
