Hello and welcome! You sound a lot like me. I'm not for sure how old you are, but I"m 26 and frustrated because I don't think I should be feeling bad this young.
I have constant diarrhea for 2 months now. I have been to a GI specialist, had a colonoscopy, upper GI and small bowel series x-rays, blood tests, & stool cultures. The Doc Dx it as IBS with diarrhea.
My Dr. suggested a high fiber diet. Here is his orders...it seems to be easing up the symptoms a bit.
Take a fiber supplement, such as metamucil. (I eat 2 apple metamucil wafers, 2 times a day...they don't taste bad.)
Add 2 pieces of fruit to your diet & continue metamucil fiber supplement.
Start to eat a high fiber cereal in the morning (I eat Fiber One) & increase your vegetable intake, continue fruit & vegetable intake & keep up the metamucil fiber supplement.
This diet may give you some gas in the beginning, but it should go away as your body adjusts to the extra fiber. It does make your stools a little more solid.
I hope this helps you. Keep me updated. We sound so much alike! It's nice to talk about this with somebody who understands.
