Congenital Sucrase-Isomaltase Deficiency (CSID)

About CSID

Congenital sucrase-isomaltase deficiency (CSID), often referred to as sucrose intolerance, is an inherited disorder that causes the digestive enzymes not to work as they should. These enzymes are required to break down and absorb carbohydrates in your diet like table sugar (sucrose) and other sugars from starches present in foods such as potatoes and baked goods. If you have CSID and eat foods with sugars and starches, you may experience diarrhea, gas, bloating and abdominal pain.
