Can Eating Sucrose Cause Diarrhea?
Diarrhea is an unpleasant symptom that may be triggered by many different factors, including your dietary intake. For some, gastrointestinal (GI) symptoms may be caused by dietary triggers including cruciferous vegetables (such as broccoli or cauliflower), wheat, dairy, or even sugar. For individuals who are sensitive to a particular food, diarrhea can occur within a few minutes of eating the particular food, or up to many hours later. Those of you who may have Sucrose Intolerance caused by Congenital Sucrase-Isomaltase Deficiency (CSID) can experience GI symptoms ranging from mild to severe.
There are thousands of foods to choose from, so determining which food contributes to a GI symptom may seem daunting. If you experience symptoms of a stomachache and diarrhea after eating, it is important to determine which foods have contributed to those symptoms. If you are unable to tolerate foods containing sucrose, a sugar that occurs in many fruits and vegetables and processed foods, it is likely contributing to the GI symptoms you feel.
What Is Sucrose?
Sucrose, or table sugar, is a disaccharide, which is two simple sugar molecules linked together by a bond. Once ingested, your body must use enzymes to break the bond between the simple sugar molecules so they can be absorbed and used by your body for fuel.
If you have CSID, your body lacks the enzymatic activity needed to split the two simple sugars; therefore, digestion and absorption of sucrose can’t take place. In addition to the uncomfortable GI symptoms that can occur when sucrose can’t be broken down, the unabsorbed sugar can also affect the rate of stomach emptying, accelerate how quickly food moves through the intestines, and contribute to the malabsorption of other nutrients.
Speak with Your Physician
CSID can cause symptoms, including a bloated stomach, diarrhea, gassiness, and abdominal pain. If you experience these GI symptoms regularly, don’t ignore them. Your physician can help you determine if you need to be tested for CSID. If you have persistent GI symptoms, take this quiz to help determine if you might have CSID. Be your own advocate and speak with your physician about your symptoms and different options, including testing for CSID.
