I had a fructose breath test and lactose breath test before having Linx surgery. They were both negative. After surgery I was still unable to get off my PPI's finally I cut out fruit and within in 2 days all acid and gas went away!! Never took another PPI. Also A1C dropped from 6.2 to 5.7, something I could never get down. Once I realized that anything with seeds is a fruit, peppers, cucumbers, tomatoes, etc my A1c went to 5.4, normal! But also no sugar or sugar products, have to be careful here because there are many names for sugar. After cheating over the holidays I was sick with horrible stomach problems for several months but back to normal now, but gained weight I can't get off! never had that problem! Yes doctors think fruit is the holy grail but 30% of the population has a fructose intolerance or malabsorption and don't know it! Also I have to make sure the fiber content from foods is low, fruits and fibers stay in the upper intestine and basically rot causing gas, pain, and acid and take several days to digest. I eat protein and vegetables and have completely normal bowel movements daily!
