Your gut microbiome is a large community of bacteria, fungi, and viruses. When it’s balanced, microbes help break down fiber, make helpful compounds, and support the gut lining.
With dysbiosis, the “mix” changes. Harmful or less-helpful microbes may grow, while beneficial microbes drop. This can reduce helpful byproducts like short-chain fatty acids.
Over time, that shift can affect gut barrier function and immune signals. A weaker gut barrier can let more triggers interact with the body, which may contribute to ongoing inflammation and digestive symptoms.
