First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study from Mayo Clinic looks at how inflammation in fat tissue may affect the liver in people with severe obesity. Researchers will measure liver stiffness and fat tissue markers in 60 adults before they have weight-loss surgery. The goal is to better understand why some people develop nonalcoholic steatohepatitis (NASH) and insulin resistance.
