Bloating After Meals – Could It Be CSID?

Bloating After Meals – Could It Be CSID?

Bloating after meals – that inflated balloon feeling in your abdomen that you may also be able to see if your stomach is distended – is a common symptom of Sucrose Intolerance due to Congenital Sucrase-Isomaltase Deficiency (CSID). But, bloating after eating could also be a sign of something else. Here’s how to determine whether CSID may be the cause and how to beat the bloat.

Why CSID Can Cause Bloating

To digest foods containing sugar, your body needs the enzymes sucrase and isomaltase, which are produced in the small intestine. If you have CSID, you don’t make a functioning form of these enzymes. Without the function of these digestive enzymes, foods containing sucrose can’t be broken down as they should be into glucose and fructose, which are the forms of sugar your body needs for fuel.

When your body can’t absorb the sucrose in food, bloating after meals can result. Instead of being converted into glucose and fructose in the small intestine, undigested sucrose travels to the large intestine (colon). Bacteria that naturally reside there feed off the undigested sugar and ferment, producing gas that builds up in the intestine and causes your stomach to distend. In addition to bloating, other symptoms of CSID include watery diarrhea, frequent bowel movements, unexplained abdominal pain and gas, vomiting, and weight loss.

Other Causes of Bloating after Meals

Other health issues, such as irritable bowel syndrome, heartburn, or celiac disease can also cause bloating after meals. Even just eating or drinking too quickly can lead to that bloated feeling if gas gets trapped in your esophagus. You might also feel like burping or belching.

Could that bloated feeling be CSID? Take the quiz to find out.

Do Your Homework

If you’re not sure bloating after meals is a problem, keeping a detailed food diary can help you spot trends, such as typically experiencing bloating after eating sugary or sweet foods such as cake, cookies, and ice cream. Food diaries can provide valuable insight into the cause of your symptoms.

For a week or two, write down everything you eat and drink, when you consumed it, how the food was prepared, and how much you ate, such as ½ cup or 8 ounces or a small slice. Track your symptoms, too. In your food diary, make note of any symptoms, such as bloating or gassiness, when it started and how long it lasted. Then make an appointment to discuss your findings with you doctor.

Team Up with Your Doctors for a Diagnosis

To help your family physician determine the problem, be specific about when you experience bloating and how long you’ve experienced it. Show the physician your food diary and go over the results of the CSID quiz. If you’re an adult with undiagnosed CSID, you probably have experienced bloating after meals since childhood! The food diary and quiz results can help you and your doctor sort this issue out.

Once you have talked with your doctor, in all likelihood, she will recommend that you see a gastroenterologist if you have symptoms of CSID. When you see the gastroenterologist, take your food diary along, too. If your symptoms persist, your gastroenterologist may suggest specific tests to determine if you have CSID. If you do, the doctor may recommend working with a registered dietitian to help manage your diet and treatment plan.
