Heavy or irregular periods

An iodine deficit can cause heavy and irregular menstrual bleeding. Because iodine is required for the production of thyroid hormones, this, like other symptoms of iodine shortage, is linked to low levels of thyroid hormones.

According to one research, 68% of women with low thyroid hormone levels had irregular menstrual periods, whereas just 12% of healthy women did. According to research, women with low thyroid hormone levels had more frequent menstrual periods with severe bleeding. This is due to low thyroid hormone levels interfering with the signals of hormones involved in the menstrual cycle.
