Hope someone can help shine some light. So Ill start here, 25 yr old Male... When I wake up my stomach cramps and I empty myself out. My stool is small and thin, indavidual pieces collecting a pile. Morining like today my stomach cramps real bad, with small stool. But the cramps are bad, like when you really have to go. I have been to the bathroom 4-5 times. The first time was like above but now its just small spurts with cramps. Also lately I have stomach discomfort, like I can feel the waste passing inside my lower stomach. I have a acid reflux problem and take Ranitidine for heartburn, also have swelling at anus witch I think is hemorrhoids.

Okay... no comments. So went to the Doc, she checked my blood everything looked good. No H ployri or Hep, anyway it all looked good. She said my liver count was a little high 91, if I remember correct. So came home things were okay for couple weeks, now I have no appitie and stomach feels shrunk with discomfort. Now I am set up to see a gastrologist for a colonoscopy and endoscopy. I have read the prep is the worst part, also read some really bad accounts during the process. Hopefully those are rare. On the reason for referral it list gastritis, abd pain, ^ LFTS. What should I look forward to, what will the Doc be looking for?

Oh guess I didnt really ask a question. What could cause the cramps and small stool?
