For about a yr now I have been having major bowel issues, some days I go as many as 10-15 times, its always watery, looks like there is skin in it, and smells very foul. There are days I cant quite make it to the bathroom and have a mistake. It doesnt matter if I eat or dont eat its always the same result. I have lost more than 50 lbs in a short period of time, any idea what is causing this? I am 45 yrs old some days its so bad I cant leave my house
