I have had diareah for several days now. It has been about 4-8 times a day and I have not had any solid stools mixed in at all. Some times it is very runny. I have cramps and nausea, my stomach makes loud noises before I need to go sometimes, and when I need to go to the bathroom, I have to go immediatly. People I have talked to think it may be stress related because I am taking 20 credit hours in school. However, I do not feel abnormally stressed. I wonder what it could be? Maybe a bacterial virus? I have had this for about 2-2 1/2 weeks now. Any help or advice is greatly appreciated!
