If you are craving sweets that fits the diagnosis of fructose malabsorption. I have been suffering with terrible IBS since I was 12, I am now 27, and just found out that I am not very tolerant to foods with fructose,lactose,glucose,or raffinose. They say if that is you, you will crave sweets and you have a bad reaction to honey, honeydew melon, watermelon, apples, cherries, onion, and a bunch of other things. Try a low FODMAPS diet. Put it in the google search engine. There is a chart that says what to eat and what not to eat and see if it helps. It has worked wonders for me!!!
