Are Stool Tests Worth It? Gut Health Facts You Should Know As someone who has been helping people with digestive health for decades, I’ve seen trends come and go. One that has persisted is stool testing — also called fecal testing or gut microbiome testing. Many functional medicine practitioners, naturopaths, and even conventional doctors recommend it. The idea sounds appealing: send in a small stool sample and get a detailed report on your gut flora. Supposedly, it reveals the root cause of your digestive issues and guides you to the right treatment. But after decades of helping people heal themselves from Crohn’s, colitis, IBS and SIBO, I can tell you that stool testing is often not worth the hype or the cost. In this article, I’ll explain why, drawing on my own experience, along with the wisdom of my friend and colleague, Natasha Trenev, founder of Natren Probiotics.
