No, I didn't mean that gluten intolerance pouchitis was more common than thought. I meant that gluten intolerance (celiac disease) is more common than was once thought. For instance, they used to think you had to experience it from early childhood, but it is common to develop in older people. They used to think it was "all or nothing," you either have it or not. But, there are varying degrees of celiac, so you can have a partial intolerance, just like you can with lactose.
Plus, you can have symptoms of celiac disease without having any pouchitis at all. The symptoms are similar, and many people assume they have pouchitis when they have increased frequency, cramping, increased gas, etc., but their pouch is fine when scoped.
