Over the last month I have diarrhea almost ever day and almost every time I eat anything. Most of the time I have yellow liquid, which I thought might be bile, in the diarrhea and it can be seen on the toilet paper. Today I drink a red gatorade on an empty stomach and a few hours later I ate some lunch and almost immediately had diarrhea that looked like the red gatorade or blood. I am almost 35 yrs old, 5ft 5in and weigh 198lbs.
