how come im still 22 and i already have IBS.

Hi, hepizoj! I've had IBS since I was in elementary school and never heard anything about it being related to old age. I've never had a problem with any type of dairy product. My biggest food trigger is raw vegetables and salads. I guess all that fiber is not kind to my digestive system. Whenever my IBS acts up, I go on a "white" diet. If it's white, I can eat it and it won't bother my stomach. As for treatment, a doctor friend once told me the thing that helped him most was eating a spoonful of Vaseline petroleum jelly. As disgusting as it sounds, it has helped me more than any other treatment. Good luck!
