This article explains how your gastroenterologist in Singapore can help you confirm or rule out food intolerance.
What is Food Intolerance?
Many people confuse food intolerance with food allergies, but they are two distinct conditions.
Food Allergy vs. Food Intolerance
- Food Allergy: Triggers an immune response, leading to severe symptoms like swelling, rashes, or anaphylaxis.
- Food Intolerance: A digestive issue where the body struggles to break down or absorb certain foods.
Common Causes of Food Intolerance:
- Lactose Intolerance: Difficulty digesting dairy products.
- Gluten Sensitivity: Trouble processing gluten-containing foods.
- Caffeine Intolerance: Adverse reactions to caffeine.
- Food Additives & Preservatives: Sensitivities to artificial ingredients.
Since food intolerance symptoms can appear hours after eating, it is often difficult to identify the trigger. This is why many people ask, can a gastroenterologist test for food intolerance? Fortunately, gastroenterologists have a variety of methods to pinpoint food intolerances accurately.
Can a Gastroenterologist Test for Food Intolerance? Here’s What You Need to Know
If you suspect food intolerance, visiting a gastroenterologist can help identify the specific foods causing your symptoms.
As aforementioned, this method involves removing certain foods from the diet for a few weeks to see if symptoms improve. Common foods eliminated include dairy, gluten, and processed foods.
After the elimination phase, suspected foods are gradually reintroduced to see if symptoms return. This method helps pinpoint the specific food or ingredient causing discomfort.
In addition to the elimination diet, gastroenterologists may recommend specific tests to help diagnose food intolerance. One of the most widely used tests is the hydrogen breath test.
This test is typically used to diagnose lactose intolerance, fructose intolerance, or small intestinal bacterial overgrowth (SIBO). The test measures the amount of hydrogen in your breath after consuming a sugar solution.
If your body cannot properly digest the sugar, bacteria in the gut produce hydrogen, which can be detected in your breath. Another test commonly used is the stool test.
This test checks for signs of digestive issues such as malabsorption or inflammation, which may suggest a food intolerance. Stool tests are particularly useful in diagnosing conditions like IBS or celiac disease, which are often linked to food sensitivities.
However, stool tests are not typically used to directly identify specific food intolerances. Food-specific IgG tests are sometimes offered as well.
These tests measure the presence of IgG antibodies in the blood, which are produced when the body is exposed to certain foods. However, the effectiveness of these tests in diagnosing food intolerance is debated, and they are not always reliable. Many gastroenterologists do not recommend IgG testing as a primary method for diagnosing food intolerance, as it can lead to false positives.
What to Expect During a Gastroenterology Appointment
If you visit a knowledgeable gastroenterologist in Singapore for food intolerance testing, you can expect a thorough evaluation of your symptoms, medical history, and diet. The doctor will likely ask detailed questions about your eating habits and when symptoms occur.
They may recommend an elimination diet to see if removing certain foods from your diet helps improve symptoms. This process can take several weeks, and it may require patience and discipline to follow.
During the consultation, your gastroenterologist will also assess your overall digestive health. They may perform physical exams or order additional tests, such as blood work or stool tests, to rule out other potential causes for your symptoms.
These tests help ensure that the issue is related to food intolerance rather than another condition, such as an infection or inflammatory bowel disease. If your gastroenterologist recommends a breath test, it’s a relatively simple procedure.
You will be asked to drink a solution containing a sugar that your body may have difficulty digesting. After drinking the solution, your breath will be tested at intervals to measure the hydrogen levels.
The test usually takes around 30 minutes to an hour, and it can help identify whether lactose intolerance, fructose intolerance, or SIBO is contributing to your symptoms. It’s important to note that testing for food intolerance is not always a one-time process.
In some cases, you may need to repeat certain tests or go through the elimination diet again to confirm the results. Also, a gastroenterologist might provide advice on how to manage food intolerances, such as suggesting dietary changes or recommending digestive aids to improve digestion.
