According to the National Institutes of Health, you are suffering from the eating disorderbulimia if you experience these binge-purge symptoms at least twice a week for 3 months:
You eat much more food than usual beyond the point of feeling full in just a short time -- especially snacks or other foods high in calories. This episode is called a binge, and while it lasts, you feel like your eating is out of control.
After a binge, you use aggressive purging tactics to try to prevent gaining weight from all the food you just ate. You might make yourself vomit or take laxatives, diuretics, enemas, or other medications. You also might use fasting or excessive exercise as part of this harmful strategy.
Your thoughts about body weight and shape dominate how you feel overall.
If you have bulimia, you probably share some common feelings that people with anorexia may have. For example, you may fear gaining weight, and always want to lose weight. However, bulimics tend not to be as concerned about their weight as anorexics are.
But unlike anorexia, which is a different eating disorder, you might be able to keep your body weight in the normal range, which helps to keep bingeing and purging a secret. But to you, bingeing can make you feel ashamed, while purging brings a temporary sense of relief.
Other Symptoms Include:
Recurrent episodes of binge eating and purging
Weight fluctuation (not necessarily weight loss, as seen in anorexia)
