I am a polio survivor and had constipation for 60+ years due to polio and scoliosis. After a routine colonoscopy, prep night never stopped and I had chronic diarrhea for 7 years. Several gastroenterologists later, I was diagnosed with colitis. With mega medication, daily diarrhea, 20 to 40 bouts daily, has stopped EXCEPT for when it flares up again and lasts for two to three weeks and may not reoccur for two months, more or less. Why did 7 years of diarrhea occur after the colonoscopy when I was constipated or over 60 years? I think this happened due to something that occurred during the colonoscopy. This was over 10 years ago, and the gastroenterologist retired. He refused to see me after the colonoscopy which I think is odd. I would just like some answers because this has taken my quality of life away, and my new gastroenterologist has no answers but says I will have recurrences the rest of my life.
