On Christmas 3 years ago I had a very bad stomach and intestinal flu. Within 3 weeks I had gained 20 pounds and 6 inches. In a few months I was 35-40 pounds overweight and my waist was increased by 12 inches and a year later, after 3 doctors annd every test known to man I was diagnosed with IBS. This hasn't changed much since. I had diverticular disease before and since I have COPD, diabetes, high chlorestrol, and one blocked artery and arthritis. I exercise 30-40 minutes each day with weights every other day; walk on treadmeal or outside if the humidity or temp isn't too bad for 30 minutes per day. I'm on a high fiber, low carbohydrates and chlorestrol, not hard foods or foods with cernals.Help. I am at a loss of what more to do.
