I'm diagnosed coeliac, lactose intolerant, IgAD and Vit D deficient. Despite very strict diet I've still been repeatedly ill, bubbly tummy, toilet dashes, fatigue, etc for quite a while. I thought it could be fructose intolerance.
I started following low-FODMAP pre-Christmas and have noticed a MASSIVE difference. Most days I don't even think about my stomach anymore!
Anyone else out there doing it who can share their experiences?
