What is the diffrence between bulimia vs binge and purge anorexia?

Weight & body image: Bulimia typically involves intake of massive amounts of calories with purging to prevent weight gain; if no purging occurs, obesity is the inevitable result. Otherwise, weight usually is within the normal range, and many with bulimia do not have major distortions in body image. Anorexia requires body weight 85% or less of expected with disturbed body image; can re restricting or binge/purge.

Both are significant problems. Please have a complete physical exam to know if you have a physical illness. Then see a clinical psychologist with expertise in multiple types of psychotherapy for help coping and a Psychiatrist for medication. A support group can be helpful.
