Hi debschmitt, I have all those things too, except the diverticuli I was diagnosed with in my 30s seem to have closed. I live a near-normal life by controlling my food choices and working on my anxiety. Both trigger IBS-C and the severe redundant colon I have doesn't help. I am 68 and active.

Through trial and error I eat zero grain, zero FODMAP, Zero meat, etc. I am almost halfway through with hypnosis therapy to lessen my anxiety as an IBS-trigger. Mineral oil is my laxative of choice. I am trying magnesium as a regular supplement to prevent constipation. See attached for more details. I really believe changing what is going on in your head and what you are putting in your gut is the best solution (for me so far).
