What is the most common thyroid disorder in women?

Hypothyroidism is indeed the most common thyroid disorder in women, particularly as they age and approach menopause. This condition occurs when the thyroid gland does not produce enough thyroid hormones, leading to a slowdown of various metabolic processes in the body. Symptoms can include fatigue, weight gain, cold intolerance, dry skin, and depression.

The prevalence of hypothyroidism is significantly higher in women than in men, making it a critical focus for healthcare providers, especially in women experiencing hormonal changes. It is often associated with autoimmune diseases, but its widespread prevalence makes it more common than other disorders like Hashimoto thyroiditis or Graves' disease.

Hashimoto thyroiditis is an autoimmune disorder that is one of the leading causes of hypothyroidism; however, not every case of Hashimoto results in overt hypothyroidism. Graves' disease is another autoimmune condition, but it typically leads to hyperthyroidism rather than hypothyroidism. Thyroid cancer, while serious, is much less common compared to these other disorders. Therefore, hypothyroidism stands out as the most frequent thyroid issue impacting women.
