I have been pretty healthy over the years, but rescently have been having some stomach problems. For the past month or so, it seems that every time I eat or drink something, it gives me diarrhea within about 10 -15 minutes. What could this be? I kind of asked this question over in the HIV forum, because of a slight chance of hiv exposure (tests so far have been neg), but I saw this forum, and thought I'd ask. It's really bad at the moment, and would like to be able to consume something without taking a trip to the restroom. Thanks for your help!
