I only have had one colonoscopy. So far no problems in that area. It was my last area not probed or screened on my body. They could see the colon in tests, but the colonoscopy camera sure gives a great view. I took the Sutab pill with a lot of prescribed water. Orange was the final color expelled, but the doctor after said i was all cleared out. Excellent. I hope you get the Dr and the prep you need to make this a smoother process for this body region.
