I seem to be sensitive to sugars. When I get better in POIS and fall for the temptation to eat bakery/wheat/cakes I always seem to get ballon stommach and then skin rashes (rosacea like) on my forehead and headaches + bad smelling urine, warm inflammation feeling in the body, bulging blood vessels and even some red eczema at the top of my willy. The symptoms doubles when having orgasm in the same period. When I do waterfast for some days those symptoms go away. This is a typhical SIBO-symptoms, but do you mean that malfunctional mastcells is the underlaying cause in the upper small intestine? Does anyone else share my symptoms?
