Diverticulosis

I think 50% of folks over 60 have diverticulitis which are pockets in the colon. When food gets trapped in the pockets and it get infected it turns into the "itis " accompanied with fever and chills meaning infection. Cipro and Flagel(antibiotics) are usually prescribed to treat the infection. My first attack was in 2003 and have had at least one a year until 2009 when I had 18 ins of my colon removed. All was well until last week and had another attack. According to my Dr what ever the underlying things that cause the pockets in the first place are still there and it can occur again over time. I have been taking fiber supplements once a day for 15 years. Most Drs now say anything can get trapped in the pockets not just seeds or nuts. I don't want to go through another colon resection.
