Is Hyperthyroidism more common in men or women?

Hyperthyroidism is indeed more common in women than in men. The condition, characterized by an overproduction of thyroid hormones, affects women at rates significantly higher than men, with estimates suggesting that women are affected about five to ten times more often than men. This gender disparity is thought to be linked to hormonal differences and autoimmune factors which play a role in the development of conditions such as Graves' disease, the most common cause of hyperthyroidism.

While hyperthyroidism can technically occur in anyone, including men and children, and its prevalence in children is relatively low compared to the adult population, the clear distinction is the higher incidence in females. This understanding of gender differences in hyperthyroidism is crucial for both diagnosis and treatment planning.
