Whatever you call it, it means this: You were born with a chemical that doesn’t work. This chemical, called an enzyme, is needed to digest sucrose (table sugar), which is found in many fruits, vegetables, and processed foods.

It doesn’t matter where the sugar comes from. A banana, which has sugar in it naturally, can be bad for you.

If your body doesn’t have the ability to break down the sugar in these foods, you’re going to feel BAD. That’s because you’ll experience extremely unpleasant CSID symptoms that can include chronic, watery diarrhea; gassiness; bloating; stomach pain; and vomiting.

Based on an examination of your clinical symptoms and test results, your doctor can determine if you have CSID and may prescribe a diet plan and/or pharmaceutical therapy.

While there’s no cure, you can do a lot to manage this condition and live well.
