The Claim

Patients with histologically confirmed non-alcoholic fatty liver disease (NAFLD) have significantly higher mean Fatigue Impact Scale scores (51, SD 38) compared to healthy controls (8, SD 12), indicating that fatigue is a major symptom in NAFLD independent of liver disease severity.

Source: Fatigue in non-alcoholic fatty liver disease (NAFLD) is significant and associates with inactivity and excessive daytime sleepiness but not with liver disease severity or insulin resistance

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.

Description
1 study reviewed
In plain English

People with non-alcoholic fatty liver disease report significantly higher levels of fatigue than people without the disease, as measured by standardized fatigue scores.

See the scientific wording

Patients with histologically confirmed non-alcoholic fatty liver disease (NAFLD) experience significantly higher levels of fatigue than healthy controls, with mean Fatigue Impact Scale scores of 51 (SD 38) versus 8 (SD 12), indicating that fatigue is a major symptom in NAFLD independent of liver disease severity.

Why this might work

Fat molecules build up in the liver and trigger constant low-grade inflammation throughout the body. This inflammation sends signals to the brain that alter how it processes energy and movement, making the person feel tired even when they haven't done much.

  1. Study: Fatigue in non-alcoholic fatty liver disease (NAFLD) is significant and associates with inactivity and excessive daytime sleepiness but not with liver disease severity or insulin resistance

    People with fatty liver disease reported much more fatigue than healthy people, even when their liver wasn't very damaged — meaning fatigue is a real and serious symptom of the disease, not just a side effect of how bad the liver is.
