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.

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 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 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.

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.

People who used to work nights don’t seem to have more health problems like diabetes or heart disease risks later on than people who never worked nights—even when you account for their age and medicines they take.
