I have just experienced my third bout of diverticulitis over the past 6 years. My first bout I spent 5 days in the hospital on IV antibiotics, and sent home with Cipro and Flagyl. I felt better in about 10 days. My second bout was 1 1/2 year later, and when the pain started, I quickly recognized it as diverticulitis, and went to my doctor who again prescribed Cipro and Flagyl with good results. Now 5 years later, I am experiencing another round of Diverticulits. I am again on Cipro and Flagyl and pain is improving. After my 2nd time with the disease, my Dr said to try to avoid constipation, as straining could worsen the diverticuli. I have been very careful to not get constipated, but the past week I have been doing some heavy cement work in the yard. (Lifting heavy cement blocks, and shoveling truckloads of gravel). I am wondering if this has not increased abdominal pressure to cause irritation to the diverticuli. I haven't heard of this being a cause, but it makes sense to me. I think I'll take it a little easier on myself now.
