I had two huge rectal fistulas that surfaced about
an inch from my anos in 2007. I was diagnosed with Cd in the colon and told the only way to heal these is with remicade. I decided to try the SCD diet instead, and in 6 months both fistulas were healed as were all my other symptoms of CD like white mucus and blood in my bms.
I followed the diet with fanatical 100% dedication and ate a lot of homemade yogurt. Yogurt is much better then probiotics since you would have to take 100 pro biotic pills to equal the amount of bacteria you get in one cup of homemade yogurt.
That was in 2007 and i have not had one symptom or fistula from my CD since then and I still follow the SCD diet, but not as fanatical as before. The only druga I have ever taken was pentassa , which I still take.
read the book, "breaking the vicious cycle" it goes into great detail about how a woman cured her daughter wit diet alone.
The doesn't always work in everyone, but you have nothing to loose and all to gain if it works for you.
