Assessing the patient for obsessive-compulsive disorder and mental issues may be helpful before diagnosing the condition, claims WebMD. The doctor conducts a medical or physical examination to determine the specific cause of the disorder. Blood tests and X-rays help determine if the patient has intestinal obstruction, anemia or infections. Close supervision and certain behavioral strategies can help keep the problem under control.
