About a year ago I started experience terrible cramping gas and bloating, much worse than before. I went to my internest who told me that I was eating too much fruit and should eliminate and slowly bring it back in.
After that I stopped most fruit except for grapes and the occasional apple or bananna, which gave me a lot of bloating. After about 6 more months of pain I found a gastro who ran a ton of tests and narrowed it down to IBS.
He sent me to the hospital and told me that I would be taking a breath test that would test different types of sugar levels. I drank that gross liquid and blew into the tube. They stoped my test early because they said my levels were too high. I came home to terrible cramping and was in the bathroom the rest of day.
That next day I met with my doctor and he told me that I was severly lactose intolerant and needed to be very careful with fruit. And thats where he left it. He told me it was all trial by error and even said that I shouldnt cut dairy out of my diet.
He said that I should test the fruits one by one and see how it made me feel. Since that day I have yet to eat any fruit as it still makes me nervous.
