Gut microbiota and non-alcoholic fatty liver disease

Recent studies show differences in gut microbiota composition between patients with fatty liver and healthy controls.

• Bacteroidetes and firmicutes are the dominant types of bacteria found in NAFLD patients, but their abundance varies across studies.
• A specific archaeon, methanobrevibacter smithii, may be linked to obesity.
• The bacterium akkermanshia municiphila may help protect against metabolic syndrome.
• Small intestinal bacterial overgrowth in NAFLD patients could disrupt gut microbiota and contribute to disease development.
• Gut microbiota may influence NAFLD progression through mechanisms such as promoting obesity, producing ethanol, triggering inflammation, and altering choline metabolism.
