Fructose intolerance is the inability to properly digest and absorb fructose. Fructose is a type of simple sugar in many foods — and it’s the main source of carbohydrates in fruit.
There are two types of fructose intolerance:
Dietary fructose intolerance means the cells in your gastrointestinal tract are unable to absorb fructose, causing gas, bloating, and diarrhea. People diagnosed with irritable bowel syndrome (IBS) may have this type of intolerance.
Hereditary fructose intolerance is a genetic condition. People with hereditary fructose intolerance lack the enzyme needed to break down fructose, so they can’t digest any type of fructose.
Fructose intolerance testing is a procedure that helps determine if your gastrointestinal symptoms are due to problems with the digestion and absorption of fructose.
For the test, your gastroenterologist at Gateway Gastroenterology measures the amount of hydrogen in your breath after consuming a high-fructose beverage. Elevated hydrogen levels in your breath indicate fructose intolerance.
Your provider at Gateway Gastroenterology gives you very specific instructions on the steps you need to take to prepare for fructose intolerance testing. That includes the types of medications and food you can and cannot consume prior to the test.
The day before fructose intolerance testing, Gateway Gastroenterology recommends you only eat hard-boiled or scrambled eggs; simple salad with oil and vinegar; baked or broiled chicken or fish; and unflavored black coffee or tea.
Eating or drinking any not permitted items may affect your test results.
You must also stop eating and drinking two hours before your test.
Gateway Gastroenterology performs fructose intolerance testing at the office. First, the technician has you breathe into a hand analyzer through a disposable breathing tube that measures your breath hydrogen levels.
Your provider has you drink a solution with fructose and collects additional breath samples every 15 to 20 minutes. They also ask about other symptoms you might have after drinking the solution, such as abdominal pain or bloating. The entire test takes two to four hours.
You can resume your usual diet and activities after the test. Your gastroenterologist analyzes the data and schedules a follow-up appointment to discuss the results.
