There are many different hormones in your body that have an impact on your period health. And with this post below written by a naturopath near Castlemaine and Bendigo, let us discover how your thyroid health impacts your monthly period.

Your thyroid is a butterfly-shaped gland in your throat that produces thyroid hormone. This hormone is important to every cell in your body. It stimulates every cell in your body, helping to ensure the burning of calories and the production of proteins. You need the thyroid hormone to help support digestion, detoxification, and ovulation.


The most common way that your thyroid impacts your period health is when it is underactive. Hypothyroidism is when your thyroid doesn’t make enough hormone. This can have a negative impact on your period health by:

  • Suppressing ovulation through the stimulation of prolactin,
  • An increased risk of PCOS by making insulin resistance worse,
  • Causing estrogen excess by impairing its healthy metabolism,
  • Causing heavy bleeding by reducing coagulation factors, and
  • Reducing the cellular energy available to your ovaries, which they need for ovulation, and without that energy causes anovulation and low levels of progesterone.

Symptoms of Hypothyroidism

Does any of this seem like it might apply to you? If it does, there are some other signs you can look for to see if your thyroid may be underactive. The most common symptoms include:

  • Fatigue, brain fog, and depression.
  • Infertility, irregular and/or heavy periods.
  • Hair loss, dry skin, and cracked heels.
  • Reoccurring digestive problems.
  • Feeling cold all the time.

These symptoms all have other causes, but your thyroid health may be involved. Especially if you have family members with a history of thyroid health issues.

Holistic Approach For Your Thyroid Health

While it is always good to have a consultation to confirm what is happening in your body, there are some things you can start to help support yourself:

  • Reduce inflammatory foods in your diet – try to avoid dairy and gluten.
  • Work to correct intestinal permeability by supporting the health of your intestinal microbiome.
  • Identify and treat any infections.
  • Support the health of the thyroid using herbs such as Withania.
  • Provide nutritional support to optimise thyroid function through appropriate supplementation with iodine and selenium.

Thyroid health is a complicated and involved topic, it is important to see a health professional for appropriate and targeted support. Especially as what you need can be very different to someone else with similar symptoms.
