Diverticulosis is supposed to be pretty common in the US because of our diet here. I can see why your meds would cause Diverticulosis because they cause chronic constipation. I usually only have flares on the left side, but a CT scan from 10 years ago showed involvement through the whole colon. A recent colonoscopy showed the same. I try to control flare- ups by eating more fiber and drinking more water. When I do have a flare, I try to manage it with a liquid diet. If you go to the ER they try to admit you and put you on antibiotics which destroys all the good bacteria with the bad. The side effects are not good. I have been diagnosed with idiopathic peripheral neuropathy. However, I am thinking that I have small fiber peripheral neuropathy, and that is what causes my issues. Whether it is PN or SFPN (my primary has dropped the ball on helping me get a real diagnosis) neither is a diagnosis, but a symptom. The symptom of neuropathy causes trouble with digestion because the digestive system is controlled by peripheral nerves. I do not know what has caused my PN or SFPN, but would like to know why others have diverticulosis and is it just the left side or the whole thing.

I have had Divirticulitis for years. A year ago this month, woke up with severe pain on left side of stomach. I suffered a Perforated Bowel resulting in emergency surgery....all from having Divirticulitis. Pain meds and Aspirin can be a huge cause for this. I now have to wear a Colostomy bag because I had 1 foot of diseased colon removed.
