The Claim
Daytime somnolence, as measured by the Epworth Sleepiness Scale, is significantly associated with fatigue severity in individuals with non-alcoholic fatty liver disease, with a correlation coefficient of r = 0.2 (p < 0.001), and this association is stronger than the association between fatigue severity and liver disease markers.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In people with non-alcoholic fatty liver disease, higher levels of daytime sleepiness measured by the Epworth Sleepiness Scale are linked to greater fatigue severity, and this link is stronger than the link between fatigue and standard liver disease markers.
See the scientific wording
Daytime somnolence, as measured by the Epworth Sleepiness Scale, is significantly associated with fatigue severity in non-alcoholic fatty liver disease, with a correlation coefficient of r = 0.2 (p < 0.001), indicating that excessive sleepiness is a stronger correlate of fatigue than liver disease markers.
Fat buildup in the liver releases chemicals that travel through the blood and affect the brain's wakefulness centers, making a person feel sleepy during the day and more tired overall, even when the liver damage is mild.
What the research says
1 studyPeople with NAFLD who feel very sleepy during the day also tend to feel much more tired overall, and this link is stronger than any connection between tiredness and how damaged their liver is.
