If you are truly concerned about the bleeding and exercising and don't need to spend so much money on another surgery and the inconvenience of an ileostomy and you can find Nopal (cactus paddles) in a whole foods supermarket, why not try putting cactus paddles in your diet? It makes absolutely no sense suffering unnecessarily because eating cactus paddles seems foreign... especially if they help prevent the bleeding. Truthfully, a J-Pouch is much more foreign than is eating cactus paddles... but for some reason you are living with a j-pouch. Just so you understand, I live with a J-pouch; am from the New York/New Jersey region, but living in Mexico for 11 years. I didn't start eating cactus paddles until April-May. They removed the bleeding from the exercise until I stopped eating them late last week. Yesterday I increased the intensity of my run and experienced serious bleeding. The irony is that I had bought Cactus Paddles around midday, but didn't cook with them. I don't believe it is necessary that I cook with them every day. But, I do believe that as long as I am increasing the intensity of my runs, I must have them in the diet at least every-other-day. Not such a great sacrifice considering the relief I achieve along with the cost effectiveness. Plus, considering their nutrient value and the fact that they are #1 next to Turmeric for natural anti-inflamatories... I would imagine that the J-Pouchers tend towards being middle-class, college educated survivors in first-world countries, well-immersed in the realities of modern disease and chronic illness. That means that you should well understand the risk of inflamation in all modern chronic illnesses and disease subsequently sparking interest in foods that decrease inflamation... What if you don't need to stop running... What if you don't need to have the ileostomy? All that is necessary is a calibration of your diet...
