Hi doctor, i'm having non stop terrible diarrhea for about 1 month plus now. have visited local hospital and my blood and urine test reports are normal. i don't know what is causing my diarrhea. please doctor help me stop this diarrhea?

Find the cause: You're going to need a workup by a competent gastroenterologist who can rule in or out: Whipple's, salmonella, shigella, villous adenoma, gluten enteropathy, tropical sprue, cryptosporidiosis, giardiasis, Crohn's, ulcerative colitis, pancreatic insufficiency from whatever cause, amebiasis, an unknown enemy giving you phenolphthalein, spirochetosis, or a bunch of others.
