I had 44 IMRT treatments during February-April 2025. Diarrhea started in March and continued daily until December, when a support group recommended adding Psyllium fiber and a probiotic daily. Bowel frequency and urgency continued, with 4-7 movements daily. A colonoscopy confirmed radiation proctitis. I took a month of Sucralfate enemas to heal bleeding and two months of Mesalamine suppositories to help reduce frequency. Still struggling, I have completed 8 of an initial 30 hyperbaric oxygen therapy treatments in the hope of accelerating and supporting healing. I am typically in the bathroom 3-4 times between 4 A.M. and 9 A.M., then it usually stops until early afternoon or even bedtime.
