If you have this disorder, you see yourself as overweight even though you are dangerously thin. The process of eating becomes an obsession. You develop unusual eating habits, such as avoiding food and meals, picking out a few foods and eating these in small quantities, or carefully weighing and portioning food. You may repeatedly check your body weight and engage in other techniques to control your weight, such as intense and compulsive exercise or purging. Purging can be done by vomiting or by abusing laxatives, enemas, and diuretics. Girls with anorexia often experience a delayed onset of their first menstrual period. Your height may also be lower than it should.
