Mine is sporadic (1-7 times a week), I usually get it when I have a trigger food or consume unhealthy products like alcohol or cigarettes... I just recently read "The Auto Immune Solution" by MD Amy Meyers and I have been on her recommended diet for about a week now. I have seen some good results! I have reduced the number of bowel movements to 1-4 a day and they're usually formed! The diet requires gluten free, lactose free, legumes free food and really encourages wholesome foods like fruits, vegetables, meats, and fish. Granted these foods cost a little more, and aren't the easiest to prepare but Dr. Meyers describes food as medicine and I think if you have crohn's disease that is a great way to look at food if you're trying to improve your symptoms. I'm scheduled to start taking Humira next week and I cannot wait to hopefully experience positive results from taking Humira and sticking to my new diet! I am sick of being tired and skinny, hopefully I am turning the corner and health gains are in my near future!
