Curious. I have a related disease (Ulcerative Colitis) and I believe that the straw that broke the camel's back for me was also a course of antibiotics. I got ill also about the same age as you. In retrospect, the initial "change" for me came years beforehand after a case of severe food poisoning. After that I struggled with certain foods; seafood for example made me instantly ill, whereas previous to the food poisoning incident I could handle almost any kind of food without issue. I have recently seen an improvement in my UC after being prescribed with large doses of Vitamin D. I was suffering badly from exhaustion and fatigue, related to the side effects of UC and the medication I have to take against it. In combination with lots of foods that help with the intestinal flora, such as yogurts and pro-biotics (Yakult) I'm feeling much more healthy. I don't think that one single thing causes these kinds of illnesses. I think it is a combination of factors that come together in a perfect storm. Genetics, stress, tiredness, diet and then damage to the intestinal flora (processed food / antibiotics) I think are all factors.
