Eating Disorders - Causes

(Page 4)

In response, people who are vulnerable to such criticism may feel compelled to strictly diet and lose weight. The term "female athlete triad" is a common and serious disorder that affects young female athletes and dancers. It includes:

• Eating disorders, including anorexia
• Amenorrhea (absent or irregular menstruation)
• Osteoporosis (bone calcium loss, which is related to low weight)

Male Athletes. Male wrestlers and lightweight rowers are also at risk for excessive dieting. Many high school wrestlers use a method called weight-cutting for rapid weight loss. This process involves food restriction and fluid depletion by using steam rooms, saunas, laxatives, and diuretics. Although male athletes are more apt to resume normal eating patterns once competition ends, studies show that the body fat levels of many wrestlers are still well below their peers during off-season and are often as low as 3% during wrestling season.

Diabetes or Other Chronic Diseases

Eating disorders may be more common in teenagers with chronic illness, such as diabetes or asthma. They are particularly serious problems for people with either type 1 or type 2 diabetes

• Binge eating (without purging) is more common in type 2 diabetes and, in fact, the obesity it causes may even trigger this diabetes in some people.
• Both bulimia and anorexia are common among young people with type 1 diabetes. The combination of diabetes and an eating disorder can have serious health consequences. Some women with diabetes omit or underuse insulin in order to control weight. If such patients develop anorexia, their extremely low weight may appear to control the diabetes for a while. Eventually, however, if they fail to take insulin and continue to lose weight, these patients develop life-threatening complications.

Early Puberty

There appears to be a greater risk for eating disorders and other emotional problems for girls who undergo early menarche and puberty, when the pressures experienced by all adolescents are intensified by experiencing these early physical changes, including normal increased body fat.
