Diverticulitis treatment, as mentioned already, is at least Flagyl 500my IV every 8 hours (if you are hospitalized). Pain/nausea control. Dietary measures are conflicting. Used to be avoiding the nuts, seedy stuff, high roughage. Then it went just the opposite. Now it is up to each doctor really. Bowel problems run in my family. My niece and a cousin have Crohn's, a nephew with inflammatory bowel disease, I've been lumped in the IBS pile. Both parents had diverticulosis with flare-ups and my Dad had the c. diff infection that I thought would never go away. I see a new GI doc next month as I'm having horrible attacks every 2-3 days despite medication.
