Overview
- Mayo experts describe fatty liver tied to metabolic dysfunction as a major driver of chronic liver disease in Western countries, often progressing silently without symptoms.
- Up to two-thirds of adults with obesity and about half of children with obesity may have fatty liver, and roughly 20% risk advancing to inflammatory disease with fibrosis if untreated.
- Early, sustained weight loss supported by a Mediterranean-style diet, management of diabetes and other risk factors, and at least 150 minutes of weekly exercise can reduce liver fat and enable recovery before cirrhosis.
- Observational studies cited by Mayo Clinic associate about three cups of caffeinated black coffee daily with slower fibrosis progression, though coffee is not a substitute for core lifestyle measures.
- Clinicians recommend avoiding alcohol even in small amounts, steering clear of unproven liver “detox” supplements, and receiving hepatitis A and B vaccines when liver damage is present.
