I have been suffering from cronic diarrhea now for several years. It s mostly watery diarrhea, and I m going like 15 to 20 times a day. A lot of the time it is after I eat, and last for a while. When I have to go, only part of it comes out, and I sit on the toilet for 10 to 30 minutes trying to go more, but only tiny amounts come out. I don t get much sleep because I m up continously going to the bathroom at night. I have messed myself 3 times today because I didn t make it to the bathroom on time. What could be causing this? What should I ask my gastro doctor to do. Can they put me in the hospital and run a battery of tests?
