Gut Examinations Demystified: Types, Methods & What to Expect

Gut examinations can vary widely, from non-invasive assessments of your gut microbiome to invasive procedures that look directly inside the digestive tract. The main types include stool-based gut microbiome testing, which analyzes the microbial composition and function from a stool sample; breath tests that screen for conditions like small intestinal bacterial overgrowth (SIBO); and endoscopic examinations such as colonoscopy or flexible sigmoidoscopy for direct visualization and tissue sampling. Capsule endoscopy offers a minimally invasive option for looking at parts of the small intestine. Understanding the purpose, what each test measures, and how long it takes can help you decide which gut examinations are most appropriate for your health goals. How these tests are performed varies. Stool-based gut microbiome testing typically uses a home collection kit, with clear instructions for sample handling and mailing the specimen to a lab. Breath tests require fasting and avoiding certain medications beforehand, then measuring gas produced after you drink a sugar solution. Endoscopic procedures like colonoscopy and flexible sigmoidoscopy involve bowel preparation, sedation, and a short recovery period, while capsule endoscopy involves swallowing a pill-sized camera that records as it travels through the gut. For all tests, your clinician will explain what to expect, potential risks, and how the results will influence your next steps.
