did you also have a colonoscopy? I would think something like that would have been found during that procedure but I'm unfamiliar with what diverticulitis is? I don't have pain. An occasional pain if I push on my stomach (left mid/bottom side) but everyone thinks I'm crazy. I'm am losing weight which makes my stomach look even bigger. The funny thing is that I feel the best in the morning and my lunch time (even if I haven't eaten anything but a banana for breakfast I take one bite of something and my stomach immediately expands. By the evening is when it's at it worse. Did they do all the other test that I mentioned above on you as well. What were your symptoms and what kind of dr. performs a Barium enema (GI dr).
Go to a different dr. I had issues the same and and finally a barium enema revealed diverticulitis. I also get concerned about the ovaries. Good luck and kee me posted
Insist on getting copies of your tests. Some doctors feel that an ovarian cyst is harmless and won't say anything. That could be causing the issue.
