Approximately one out of every eight women will experience thyroid issues in their lifetime. The likelihood of women acquiring a thyroid disorder is 10 times higher than that of men. Thyroid problems can affect the menstrual cycle, pregnancy, and menopause in a number of ways.

Menstrual cycle

Thyroid problems can cause a variety of menstrual cycle irregularities, including:

  • Heavy or prolonged periods
  • Light or infrequent periods
  • Irregular periods
  • Missed periods (amenorrhea)


Thyroid problems can make it more difficult to get pregnant and can also increase the risk of miscarriage and stillbirth.


Thyroid problems can trigger early menopause or make menopause symptoms more severe.

Here is a more detailed look at how thyroid problems can affect each of these life stages

Menstrual cycle

The thyroid gland plays a role in the production of reproductive hormones, such as estrogen and progesterone. When the thyroid gland is not functioning properly, it can disrupt the balance of these hormones and lead to menstrual cycle irregularities.

For example, hypothyroidism (underactive thyroid) can cause heavy or prolonged periods, while hyperthyroidism (overactive thyroid) can cause light or infrequent periods. Thyroid problems can also cause irregular periods and missed periods.


Thyroid hormones are essential for the normal development of the foetus. Women with hypothyroidism or hyperthyroidism who are not adequately treated are at increased risk of miscarriage and stillbirth.


The thyroid gland can also play a role in menopause. Women with hypothyroidism may experience early menopause, while women with hyperthyroidism may experience more severe menopause symptoms.

If you are concerned about how thyroid problems may be affecting your menstrual cycle, pregnancy, or menopause, talk to your doctor. They can test your thyroid function and recommend the appropriate treatment.
