Leaky Gut Test | Lactulose/Mannitol | New York

Ordering the Leaky Gut Test | Lactulose/Mannitol | New York

The Leaky Gut Test | Lactulose/Mannitol | New York helps measure how well your small intestine absorbs nutrients and keeps out unwanted particles. This test is often used to check for issues like poor nutrient absorption, food sensitivities, and digestive discomfort. Interestingly, the test uses two sugars—lactulose and mannitol—because they are absorbed differently, which helps pinpoint where the gut barrier may be weak.

Ordering this test can help you:

• Identify if your gut lining is letting larger molecules pass through, which may cause immune reactions.
• Find out if your body is absorbing nutrients properly, which can affect energy and digestion.
• Track changes in gut health over time, especially if you are making diet or lifestyle changes.
• Detect hidden gut issues that may not show up on other tests.
• Support your doctor in creating a more targeted treatment plan for digestive symptoms.

Who Should Consider Intestinal Permeability and Absorption Testing

People who have ongoing bloating, stomach pain, or unexplained tiredness may benefit from this test. For example, someone who has tried different diets and still feels gassy or tired after eating could use this test to find out if their gut lining is letting in things it shouldn’t.

Ordering this test may also be helpful if you:

• Have frequent diarrhea or constipation that doesn’t improve with simple changes.
• Notice skin rashes or breakouts that seem linked to what you eat.
• Experience brain fog or trouble focusing after meals.
• Have a history of autoimmune conditions or food allergies.
• Recently took antibiotics and now have new digestive symptoms, as antibiotics can sometimes change gut barrier function.

Pinpointing gut barrier problems can help you and your doctor make specific changes to improve nutrient absorption and reduce unwanted symptoms. Delaying this test could mean missing early signs of gut issues, which may make symptoms harder to manage later.

Preparing for Gut Barrier and Absorption Lab Testing

Fasting is required for at least 8 hours before starting the test, and you should avoid certain foods like strawberries, celery, and mushrooms for 48 hours before collecting your sample.
