Just as there is fat, frutose, lactose etc malabsorption is it possible there is carbohydrate malabsorption. IS THERE A TEST AVAILABLE FOR IT IF THERE IS SUCH A THING?Getting desperate to find answers to my ibs.Tried plenty of things, nothing has worked. Currently am taking Calcium carbonate, digestive enzymes with each meal, pepto, fibre 2x a day, no dairy. Tried many many different things in the past including prescription meds, nothing works. Only improvement is seen when I stay off ALL GRAINS AND TABLE SUGAR, not complete resolution. But it is next to impossible to stay on the SCD for too long. Help!
