What is Leaky Gut Syndrome?

The gastrointestinal (GI) tract is a tube of connected organs that runs from the mouth to the anus. The organs of the GI tract include:

Digestive enzymes in the stomach and small intestine break down nutrients in food and drink into smaller molecules that the body uses for energy, growth, and maintenance.

The intestines also play an essential part in protecting the body from harmful bacteria and toxins. Tight openings in the intestinal walls allow water and nutrients to pass through into the bloodstream while keeping harmful substances inside. In LGS, these openings become larger, allowing food particles, bacteria, and toxins to pass directly into the bloodstream.

The intestines are also home to a wide range of bacteria called the gut microbiota. These bacteria help digestion, protect the intestinal wall and support regular immune function. LGS may involve imbalances in gut microbiota. According to a 2016 article, imbalances in the gut microbiota can trigger the body’s immune response. This causes gut inflammation and increased intestinal permeability (IP). IP refers to how easily substances can leak out of the intestines and into the bloodstream.


Leaky gut shares many of its symptoms with other health conditions. This can make the disorder hard for doctors to identify.

Leaky gut may cause or contribute to the following symptoms:

Causes and Risk Factors

Professionals do not yet know exactly what causes leaky gut syndrome. However, various risk factors can disrupt the gut microbiota and contribute to increased IP. Examples include:
