The Study
Author Correction: Perceived stress and non-alcoholic fatty liver disease in apparently healthy men and women
This study looked at whether people who feel more stressed also tend to have more fatty liver, and found a link. But it didn't watch people over time, so we don't know if stress made the liver sick, or if having a sick liver made people feel more stressed.

Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes — this means high stress might be a meaningful risk factor for fatty liver, even after accounting for weight, diet, and other health habits.
- 2People with the highest stress levels (PSI score 27) were about 1.8 times more likely to have fatty liver disease than those with the lowest stress levels (PSI score 10).
