What is the main cause of hypothyroidism in females?

The most common cause of hypothyroidism in women is Hashimoto’s disease, an autoimmune disorder where the immune system attacks the thyroid gland. 🩺 Other significant causes include treatment for hyperthyroidism (like radioactive iodine), thyroid surgery, radiation therapy to the neck area, and certain medications. Iodine deficiency is also a major cause globally, though less common in developed nations.
