Heavy periods are one of the more common hypothyroidism symptoms.

The thyroid gland affects the metabolic function of virtually every organ in the body. An underactive thyroid gland produces less T3 (triiodothyronine) and T4 (thyroxine) hormones.

A decline in T3 and T4 impacts the production of the hormones that control the menstrual cycle. When menstruation occurs, women with hypothyroidism may experience greater blood loss.

If you are experiencing heavy periods, it may be a symptom of hypothyroidism. Speak to your doctor about arranging a thyroid test.
