hi, my brother-in-law and best friend has been experiencing large amounts of diarreha for the past 4 weeks, with this he has also lost 20 pounds and he continues to lose weight everyday. the first week he went to the hospital because he couldnt control it he also had a fever and was dehydrated. They did testing and gave him a I.V to rehydrate him but all the tests came back normal, they did after 2 weeks give him a pill that is supposed to be a little stronger then immodium but it has only slowed it down not fixed it. he has since been back to the hospital and they keep telling him that everything is fine and it will go away, but why the weightloss and still diarreha does anybody know what else it could be or what else he should do he thinks hes dying i think hes crazy but who knows how sick he really is when doctors wont do there job!!! sombody please help
