There are two subgroups of anorexic behavior aimed at reducing caloric intake, including the following:
- Purging type – regularly makes themselves throw up or misuses laxatives, diuretics, enemas, or other cathartics (medications, through their chemical effects, that serve to increase the clearing of intestinal contents).
- Non-purging type – uses other inappropriate behaviors, such as fasting or excessive exercise, rather than regularly engaging in purging behaviors to reduce caloric absorption of excessive amounts of food by the body.
The following are the most common symptoms of bulimia.

- Self-induced vomiting (usually secretive)
- Excessive exercise or fasting
- Peculiar eating habits or rituals
