I have had chronic constipation for months. I had a Ladd’s procedure in November of 2011 and ever since I have had chronic constipation. Three days ago I had a colonoscopy to look at why this was happening. During the colonoscopy prep I passed only a little bit of stool one time and the rest of the time it was basically clear liquid. This worries me because I have been constipated for so long so why wouldn’t hardly anything come out? I have a distended stomach, throbbing stabbing aching pains in my stomach and tenderness to touch, I always feel incredibly full or bloated and after I eat I feel the need to throw up. I’m just very concerned because I know that after my surgery it is common to have a bowel obstruction and my symptoms are very similar to that of one. Should be concerned or possible reasons why my body didn’t pass a lot of stool during the colonoscopy prep after months of constipation. Do you think this could be an obstruction or something else?
