Bulimia signs and symptoms may include: 
Being preoccupied with your body shape and weight 
Living in fear of gaining weight
Repeated episodes of eating abnormally large amounts of food in one sitting
Feeling a loss of control during bingeing — like you can't stop eating or can't control what you eat
Forcing yourself to vomit or exercising too much to keep from gaining weight after bingeing
Using laxatives, diuretics or enemas after eating when they're not needed
Fasting, restricting calories or avoiding certain foods between binges
Using dietary supplements or herbal products excessively for weight loss
 The severity of bulimia is determined by the number of times a week that you purge, usually at least once a week for at least three months.
