The Claim
In community-dwelling adults aged 42–99, the prevalence of thyroid medication use is 24% among women and 9% among men, and a majority of women using thyroid hormone report using it for nonspecific symptoms such as fatigue or weight control.
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.
Among adults aged 42 to 99, 24% of women and 9% of men use thyroid medication. Most women who take it report doing so for symptoms like fatigue or weight control.
See the scientific wording
Thyroid medication use is significantly more common in women (24%) than in men (9%) in community-dwelling adults aged 42–99, and a majority of women report using thyroid hormone for nonspecific symptoms such as fatigue or weight control, which may confound associations between TSH and mood or cognition.
Women are more likely to report nonspecific symptoms like fatigue and weight gain, leading to thyroid hormone prescriptions even when thyroid function is normal. Men report these symptoms less often, so they receive fewer prescriptions. This difference in prescribing is not due to differences in thyroid biology but to differences in how symptoms are communicated and interpreted.
What the research says
1 studyStudy: The Association of Thyroid Stimulating Hormone Levels with Cognitive Function and Depressed Mood
This study found that about 1 in 4 older women take thyroid pills, often for vague reasons like tiredness or weight gain, while only about 1 in 10 men do — just like the claim says. It also shows this difference might make it harder to tell if thyroid levels really affect mood or memory.
