Sugar test during surgery may unlock secrets of fatty liver disease

This study looks at how the liver reacts to a sugar injection during bariatric surgery in people with obesity, comparing those with and without fatty liver disease (MASLD). Forty adults will receive either a sugar solution or salt water during surgery, and small tissue samples will be taken to measure changes in gene activity. The goal is to understand why MASLD develops and how the liver handles sugar, which could lead to better ways to diagnose or treat the condition.
