Diarrhexia 

a disorder in which the sufferer attempts to lose weight by using laxatives. The disorder is characterized by extremely low body weight, distorted body image, an obsessive fear of gaining weight, and an aching rear from over exposure to acidic feces.

I have to go to my diarrhexia support group today and talk about my constant use of laxatives to lose weight. Our motto is: "My problems ain't shit!"
