Bulimia (say "boo-LEE-mee-uh") is an eating disorder that causes people to eat a large amount of food in a short time (binge). During a binge, they feel out of control and feel unable to stop eating. After a binge, they do something to prevent weight gain. They may vomit or take laxatives to get rid of food (purge). Or they may exercise too much or go without food (fast). This becomes a cycle.
People can be any size or weight and have bulimia. And they usually have trouble accepting that it's a problem. But over time, it can cause serious health issues. With treatment, many people can recover from bulimia.
