Every morning i have a bowel movement at least 4 times in an hour, most of which is loose and watery. what could be wrong?

Could be normal: What's considered a normal bowel movement varies from one person to the next. In general, most people have it 3 x/day to 3 x/week. 4 times in an hour with loose, watery consistency sounds a bit unusual, but the important question is whether or not this is a new pattern for you or you have always had it this way. If it's something new, it could be diarrhea due to a number of possible causes.

Coffee?: Morning caffeine intake can cause that. Back to basics: daily fiber supplement, more water, cut caffeine intake by one half. If your symptoms persist, see your doctor.
