People who naturally stay up late might be more likely to develop a fatty liver if they work night shifts or irregular hours, because their body clock doesn’t match their work schedule.

People who work nights or irregular shifts are more likely to develop a fatty liver condition, especially if they do it for a long time or often — this might be because their body’s internal clock gets messed up.

People in their 20s, especially women who work nights or irregular hours, might be more likely to develop a fatty liver condition than older workers, because their bodies may react more strongly to disrupted sleep schedules.

Working irregular hours or not sleeping well can mess up your body’s internal clock, which in turn hurts your metabolism and liver — making it harder for your body to process food and stay healthy.

People who work nights more than three times a week are more likely to develop a type of liver fat buildup than those who rarely or never work nights — and the more nights they work, the higher the risk.

Working nights might affect your health differently depending on things like your gender, when you naturally feel awake or sleepy, or how much money you make — but this study didn’t check any of those things, so we can’t fully explain why other studies have found different results.
