I certainly understand what you’re going through. I’m 74 years old and have had digestive issues for a long time. I also have a tortuous colon with diverticulosis, GERD and gastroparesis. I’ve had 2 bouts of diverticulitis in the last year, treated with antibiotics and flagyl. After the second one my GI Nurse practitioner sent me to a colorectal surgeon who was very thorough and explained that removing the sigmoid will certainly help with preventing a perforation of the diverticuli, thus causing emergency surgery with a colostomy that could be permanent for life. So I underwent my third colonoscopy in a year because the other doctors who performed the first 2 could not get all the way through my colon due to the many twists and turns. He was able to complete the test, found a small noncancerous polyp and removed it. I have an appointment to follow up with him next month to see what the next step will be. I’ve had no bowel issues since the colonoscopy. I’ve seen a dietician about my diet, drink 9-10 glasses of water per day and try to eat 15-20 grams of fiber per day. I don't take any laxatives, have 1-2 bowel movements each day but still have periods of bloating and gas. It’s kinda trial and error to figure out what you can and cannot eat. I followed a modified FODMAP diet for 4 years and it did help. The biggest thing for me is drinking lots of water to fight the constipation that causes the diverticulosis. So i hope you can get the help you need. GI issues can really be miserable! Wish you the best.
