The Claim

Individuals with overt hypothyroidism have a significantly higher prevalence of abnormal liver enzymes (ALT >33 IU/L for men and >25 IU/L for women) compared to individuals with subclinical hypothyroidism or euthyroid controls.

Source: Non-alcoholic fatty liver disease across the spectrum of hypothyroidism.

In plain English

People with overt hypothyroidism are more likely to have elevated liver enzyme levels than those with subclinical hypothyroidism or normal thyroid function.

See the scientific wording

Abnormal liver enzymes (ALT >33/25 IU/L for men/women) are significantly more prevalent in individuals with overt hypothyroidism (25.9%) than in those with subclinical hypothyroidism (20.1%) or euthyroid controls, indicating that thyroid dysfunction may contribute to liver cell injury beyond fat accumulation.

Why this might work

Low thyroid hormone levels slow down the liver's ability to burn fat for energy, causing fat to build up inside liver cells. This overload stresses the cells, damaging their membranes and causing enzymes to leak into the blood.

  1. Study: Non-alcoholic fatty liver disease across the spectrum of hypothyroidism.

    People with worse thyroid problems (overt hypothyroidism) were more likely to have high liver enzyme levels than those with milder forms, suggesting the thyroid issue itself may be hurting the liver — not just fat buildup.
