That's weird about
the caffeine. It's actually been known to irritate IBS and IBD. I know it bothers my digestive system, even decaf coffee which is supposed to be about
97% caffeine free.
My granddad died from smoking at the age of 50. Considering that I'm 48, I feel this is way too young of an age to die. Smoking kills, but UC, well you can get surgery and get your colon taken out. There is no reason to risk dying from UC when you don't have to.
Colitis is in remission. No longer get IBS.
Figuring out how to reduce a flare or get into remission is a trial and error experience. Don't expect your GI to have all the answers. He was trained in making diagnoses, prescribing medications, and surgically removing the colon. He was not trained in alternative treatments. That's why they are called alternative treatments.
What works for me: Fecal transplantation, Probiotics, Anti-inflammatory foods, No HFCS, No crystalline fructose, No foods high in fructose, No artificial sweeteners, No pro-inflammatory foods when flaring, vitamins & supplements, Lexapro (for stress).
