What’s the link between hyperthyroidism and your menstrual cycle?

Hyperthyroidism can increase the production of prolactin which affects your menstrual cycle. It happens because thyroid hormones regulate the menstrual cycle. Any abnormality/ imbalance in the levels of thyroid hormones can impact the menstrual cycle. 

When the thyroid gland releases too much thyroid hormone in the blood it stimulates your brain to produce prolactin hormone. Elevated levels of prolactin can interfere with the normal production of estrogen and progesterone hormones, as these are the main hormones that regulate your menstrual cycle. Elevated levels of prolactin also disrupt ovulation, which also leads to cycle irregularities.  

Additionally, high prolactin levels also reduce the production of gonadotropin-releasing hormone (GnRH), which is a hormone that stimulates the pituitary gland to produce follicle-stimulating hormone (FSH) and luteinizing hormone (LH). These hormones influence the menstrual cycle by stimulating your ovary to produce an egg. If FSH and LH are low, an egg is never released from the ovaries.  

All of these disrupt periods and cause very light, irregular periods, and in some cases, you may miss your periods for several months at a time. 

How to manage hyperthyroidism-related menstrual changes? 

To manage hyperthyroidism-related menstrual changes you need to address the underlying condition that causes you hyperthyroidism. Taking treatment for hyperthyroidism can resolve menstrual problems in the majority of cases. 

For that, your healthcare professional may examine your thyroid gland by ordering a physical exam, thyroid scan, blood test, or radioactive iodine uptake test to find the cause that affects your thyroid gland production.  

Here are the available options for hyperthyroidism treatment 

  • Medications: Certain types of medication reduce the production of thyroid hormones. 
  • Radioactive iodine treatment: This treatment involves drinking or ingesting a mixture of iodine and radioactive isotope to make thyroid cells visible on a monitor; the radiation is used to destroy thyroid cells.  
  • Thyroid surgery: In this procedure, a part or whole thyroid gland is removed through surgery. And you need to take thyroid replacement medications lifelong.  

Some healthcare professionals also make some dietary changes like a temporary elimination diet, introducing an anti-inflammatory diet, or going gluten-free. To maintain optimal thyroid function, your doctor may recommend taking multivitamin supplements or thyroid-supporting minerals like zinc, selenium, and iodine, with vitamins C and E.
