A recent study published in the journal Alcohol suggests that a liver hormone, fibroblast growth factor 21 (FGF21), may play a significant role in alcohol use disorder (AUD). The researchers found that after alcohol consumption, individuals diagnosed with AUD showed a greater increase in FGF21 levels compared to healthy individuals with no family history of AUD. This finding could point to FGF21 being involved in the body’s response to alcohol and its role in the development of AUD, potentially leading to new approaches for treatment. Alcohol use disorder is a condition that affects millions o…
