Leaky Gut Explained: Symptoms, Causes, and Practical Steps to Support Digestive Health

Leaky gut is a term many people encounter when trying to understand digestive health. In scientific terms, it relates to intestinal permeability—the idea that the gut barrier may become more or less porous, potentially influencing inflammation, digestion, and overall comfort. Common symptoms people associate with leaky gut include bloating, gas, abdominal cramps, irregular stools, and sensitivities to certain foods. You might also notice persistent fatigue, brain fog, or skin issues. It’s important to note that “leaky gut” is not a standalone medical diagnosis for most conditions; rather, it can signal underlying gut barrier stress that deserves a closer look with a clinician. If symptoms persist, seeking professional guidance helps you map a safe, evidence-based plan to support your digestive health. There are several known factors that can influence gut permeability and contribute to a leaky gut picture, including infections, chronic stress, medications like NSAIDs, excessive alcohol, an imbalanced diet, and antibiotics that disrupt the microbiome. A growing body of research emphasizes the link between the gut microbiome and barrier function, suggesting that cultivating a healthy microbial balance may support gut integrity. For people curious about their own gut health, a data-driven approach can be especially informative. A science‑backed option to explore this is to test your gut microbiome with the InnerBuddies microbiome test. This consumer-friendly solution is part of a broader Gut Health Operating System that powers both consumer and partner products, bringing quantified insights into your hands InnerBuddies microbiome test. If you’re looking to take practical next steps today, focus on proven, scalable habits that support your gut barrier. Aim for a diverse, fiber-rich diet with plenty of plant foods, which nurtures a balanced microbiome. Include fermented foods that provide beneficial enzymes and microbes, stay well-hydrated, and minimize heavily processed items and added sugars that can disrupt gut balance. Prioritize sleep and stress management, because chronic stress and poor rest can affect gut permeability, and incorporate regular physical activity.
