[Life-threatening bleeding in obsessive-compulsive disorder]

We report on a case of life-threatening hemorrhoidal bleeding due to obsessive-compulsive disorder. The patient had irrational fears and felt compelled to defecate at least 3 times a day. This required massive abdominal pressing and caused inguinal hernias and prolapsed hemorrhoids. Severe obsessive-compulsive rituals may often result in physical complications. Conversely, obsessive-compulsive disorder should be considered when patients present with uncommon physical complaints, particularly skin symptoms or abnormalities in the context of micturition and defecation.
