Bulimia Nervosa symptoms explained                                                                                              

1. Binge Eating

All of us will overeat now and then; doing so is pretty normal behavior. For instance at Thanksgiving, we all sit down at the dinner table and probably overindulge. Binge eating in bulimia has certain characteristics that make it much different.

A binge is defined by several characteristics, including consuming a larger amount of food than most people would eat during the same time period (potentially thousands of calories) within a short period of time (typically 2 hours or less). It is also characterized by a feeling that one CANNOT STOP or CONTROL one's eating, accompanied by physical or emotional distress.

2. Purging

Following a binge, an individual may feel consumed with fear, guilt or shame and the need to try to undo his/her behavior. Purging is a way to compensate for binging. Purge behaviors come in many forms: vomiting, taking laxatives or water pills, starving or excessive exercise.

It is important to recognize that purging rarely works well for weight loss. Laxatives and diuretics make a person lose water not weight. Even vomiting seems to be ineffective; it has been reported that 50-75% of the calories have already been absorbed.

3. Bingeing and Purging occurs more than 2 x a week for at least 3 months  

4.Body Image: Self evaluation and self esteem is overly influenced by weight and shape

Many people in our culture are concerned with how they look, what they weigh or how to change the body parts they don't like. In bulimia, there is an intense connection between self respect and the way the body looks. We can be great in a lot of things, but if our thighs are too big, well then, we are just not good enough.

What about weight in bulimia nervosa?
Weight can be normal, underweight or overweight. Unlike anorexics who can be often identified by their low weight, it is more difficult to identify bulimics. Weight can also dramatically shift, and large swings might be an indicator that someone is developing an eating disorder.
