3. Reduced Menstrual Flow in Women (Hyperthyroidism)
The thyroid plays a number of vital roles, mostly in the regulation of different processes happening inside the body. One of these processes is the menstrual cycle which, in premenopausal women, happens every 28 days.
This regular cycle can be directly affected by the over-activity of the thyroid caused by the hormone Thyrotropin or TRH, which also acts on the ovaries, resulting in a reduction in menstrual flow.
