Leaky gut syndrome is a proposed digestive condition where the intestinal lining allows bacteria and toxins into the bloodstream. It refers to an increase in permeability of the intestinal lining, which could play a role in Crohn’s and other diseases.
Many doctors and healthcare professionals do not recognize leaky gut syndrome (LGS) as a diagnosable condition. However, further research into the area may help doctors to better understand the mechanisms and implications in humans.
Some theorize that in leaky gut syndrome, gaps in the intestinal walls allow bacteria and other toxins to pass into the bloodstream.
In this article, we discuss LGS, as well as its proposed symptoms, causes, and risk factors.
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 repair.
Tight openings in the intestinal walls allow water and nutrients to pass through into the bloodstream while keeping harmful substances inside. The rate of this passing is known as intestinal permeability (IP).
People often refer to
Gut microbiota and leaky gut syndrome
The intestines are also home to a wide range of bacteria called gut microbiota.
Imbalanced in gut microbiota can impact the overall health of the intestine, including permeability.
A chronic increase in IP may contribute to several health conditions, such as:
- irritable bowel syndrome (IBS)
- Crohn’s disease
- celiac disease
- chronic liver disease
- food allergies and sensitivities
- polycystic ovary syndrome
Scientists have also been investigating the
Many proposed LGS symptoms are similar to other health conditions. This can make the condition difficult for doctors to identify.
LGS may cause or contribute to the following symptoms:
There are no definable causes of leaky gut syndrome. However, various
However, there is no conclusive proof to support claims that LGS plays a role in any of these conditions.
Gut microbiota and autism
In a small 2017 study, researchers compared stool samples from two groups of children — autistic children with GI symptoms, and those without autism or GI symptoms. The researchers identified significantly higher amounts of Clostridium perfringens bacteria in samples collected from autistic children with GI symptoms.
However, the direction of association between gut microbiota and autism is unclear.
Since many doctors do not consider leaky gut to be a legitimate medical condition, there is no standard treatment.
However, certain dietary and lifestyle changes may help people to improve the strength of their intestinal barrier..
The following dietary tips may help to improve gut health:
- eating foods rich in prebiotic fiber, such as vegetables and whole grains
- eating less meat, dairy, and eggs
- avoiding added sugar and artificial sweeteners
The following lifestyle changes can improve digestion and support a healthy gut:
Leaky gut syndrome is a proposed intestinal condition in which a weakening of the intestinal walls allows bacteria and toxins into the bloodstream.
Many medical professionals do not recognize LGS as a diagnosable condition, and more research is necessary to understand the mechanisms and implications in humans.
