I'm having gi issues for 2 months. blood and mucus diagnosed as likely from hemmorhoid. that's gone but i now have diarrhea every 1-2 weeks. cause?

Sigmoidoscopy: You may need a sigmoidoscopy based on your history. Sometimes irritable bowel syndrome can cause diarrhea - or there could be a problem with the bacteria in your gut (especially if recent antibiotics). A gastroenterologist can help sort out possible causes and treatments. In the meantime, try cutting out caffeine, get high fiber and mild exercise. Some people also benefit from probiotics OTC.
