Hi, I am 27, 175 LBS, 5'9" , having diarrhea on and off for about a month, no stomach pain or blood in stool, feel normal. I have been taking atenolol(25mg), lisinopril and hydrothoroclyicide(12.5mg). I had my blood checked about 3 months ago, doctor said everything is fine at that time. Also sometimes I wake up sweating. My diet is pretty good. Any ideas on what it could be?
