### input:
I recently went to my doctor due to some cramping in my lower abdomen, mostly on the left side & because I noticed I was passing large white chunks along with my stool (about grape-size). My doctor put me on 2 antibiotics to treat possible diverticulitis or colitis & set up a CT scan . The CT scan showed no Diverticulitis, but did show that my colon wall is thickened, so I m being sent for a colonoscopy next week. In the meantime I m trying to figure out what s going on with my body.....I don t know if it was the antibiotics, which did upset my stomach, but the past few days my belly is so bloated & distended I look as if I m 5 months pregnant, the lower left pain is constantly aching followed by short stabbing pains, my stomach always feels full so it s very hard to eat much. My doctor said I may have Crohns or UC, will either of these diseases show up on the colonoscopy? And is there anything I can do before then to reduce the bloating/fullness?

### output:

Hi welcome to Chat Doctor forum.  Thanks for calling Chat Doctor. F.  As you describe you are going to have colonoscopy, and possible diagnosis could be Crohn's disease, or ulcerative colitis. You want some remission in the meantime.  I advise you to avoid spices, junk foods, and oily foods to prevent irritation of the gut, and hence motility.  Take bland foods as far as possible, in small amounts at a time and more times. Take more of water.  You can take antacid liquids for soothing the gut.  Wishing for a quick recovery.  Best regards.
