Two of the worlds most serious eating disorders are bulimia, which involves consuming large amounts of food and then purging them by either laxative abuse or self-induced vomiting; and anorexia nervosa, which is characterized by distorted body image and self-starvation. Although anorexia and bulimia are two separate disorders, many of those who are affected exhibit features of both.
More than 90 percent of those who suffer from these disorders are young women and adolescent girls. Anorexia usually begins when the their young bodies begin to change during early adolescence and the more their bodies change, the more convinced they become that they are getting fat.
Warning Signs of Anorexia
Warning Signs of Bulimia
Causes
Some researchers suggest that eating disorders could be caused by chemical and hormonal imbalances in the brain, while other experts firmly believe that problematic family relationships are to blame. Anorectics are often overachievers and often described by their parents as being "obedient". Some psychiatrists theorize that their erratic eating patterns represent the only aspect of their lives that they feel they are able to control.
Bulimia and anorexia are both potentially fatal. There is a high suicide rate for bulimics, while anorectics can quite literally starve themselves to death. Changes to their bodies caused by poor nutrition and erratic eating habits also puts them at a much higher risk for heart disease and stroke.
Diagnosis
Even if there are signs of an eating disorder, the first step is always a complete physical examination. This will rule out other illnesses that can cause drastic weight loss such as chronic infection or some cancers. During the examination the doctor will carefully look for any signs of bulimia or anorexia. In anorectics, thinning / brittle hair and dry skin are common. Low blood pressure and a slow heart rate indicate that the body might be responding to starvation.
In diagnosing bulimics, much depends on a physical exam and medical history. The doctor will examine the patient`s mouth to check for swelling of the esophagus due to repeated vomiting and check the teeth for signs of deterioration from prolonged exposure to stomach acids found in vomit.
Treatment
Treatment for eating disorders requires both medical and psychological care.
