Thyroid Health and Menopause

Thyroid Health and Menopause

Menopause marks the end of a woman’s reproductive years, typically occurring in her late 40s or early 50s. It is diagnosed after 12 consecutive months without a menstrual period. Menopause is a gradual process that includes three stages: perimenopause, menopause, and postmenopause. Each stage has distinct characteristics and symptoms. Perimenopause is a transition period which can last for several years, and is characterized by hormonal fluctuations. General symptoms of menopause include hot flashes, night sweats, mood swings, and changes in menstrual cycles. These symptoms result from declining estrogen levels.

Here’s the tricky part: the symptoms of menopause and thyroid disorders can overlap, making it challenging to distinguish one from the other. This overlap can lead to a misdiagnosis or delayed treatment. Thyroid disorders are, in fact, more common in women than in men, with a higher prevalence in postmenopausal and elderly women especially. This shows how important comprehensive health evaluations are during and after the menopausal transition. 

In this article, we will learn about the connection between thyroid health and menopause and discuss why thyroid health monitoring is important during all stages of menopause.

What is the connection between thyroid health and menopause?

The transition to menopause involves significant hormonal changes, including fluctuations in estrogen and progesterone levels. These hormonal changes can influence thyroid function in the following ways:

1. Hormonal Interplay

Estrogen has a complex relationship with thyroid hormones, including influencing the levels of thyroid-binding globulin (TBG), a protein that transports thyroid hormones in the blood. Estrogen also influences the body’s response to thyroid hormones. The decline in estrogen levels during menopause can therefore negatively affect thyroid function, and may worsen or mimic symptoms of hypothyroidism.

2. Immune System Changes

Menopause is associated with a higher prevalence of autoimmune thyroid diseases. Hashimoto’s thyroiditis (a major cause of hypothyroidism) and Graves’ disease (the leading cause of hyperthyroidism) are the two main autoimmune diseases that affect the thyroid. According to research, estrogen modulates the production of cytokines, which are crucial for immune cell communication. For example, it can enhance the production of anti-inflammatory cytokines, while reducing pro-inflammatory cytokines. During menopause, the decline in estrogen levels can reduce the regulatory effects of estrogen on immune cells, potentially leading to an increase in inflammatory responses and a higher susceptibility to autoimmune diseases.

Why is it necessary to monitor thyroid health during and after menopause?

There are many compelling reasons to monitor thyroid health in perimenopausal, menopausal, and postmenopausal women. First, let’s briefly address the cardiovascular risks associated with menopause. Untreated hypothyroidism, in particular, can worsen these risks due to its association with elevated cholesterol levels and blood pressure.

There are also bone health concerns associated with menopause. Interestingly, both hypothyroidism and hyperthyroidism can contribute to bone loss, increasing the risk of osteoporosis, a common concern during menopause.

Moreover, hyperthyroidism may also worsen common menopausal symptoms like hot flashes, night sweats, and irregular periods (which are typical during perimenopause). Due to the symptom overlap between menopause and thyroid disorders, your doctor may perform a comprehensive medical history review and blood tests to measure hormone levels, including thyroid-stimulating hormone (TSH) and estrogen levels, to arrive at an accurate diagnosis.

If your doctor diagnoses a thyroid condition, then treatment, along with some lifestyle and dietary adjustments, can help manage symptoms and improve overall health. Usually, treatment involves medication to normalize thyroid hormone levels. 

For menopausal symptoms unrelated to thyroid issues, lifestyle modifications, hormone replacement therapy (HRT), or other treatments might be recommended based on individual health status and preferences.

Key takeaways

  • Thyroid disorders are more prevalent among postmenopausal women, highlighting the need for regular thyroid function monitoring during this period.
  • During menopause, estrogen levels drop. This can nudge your thyroid function a little out of order, especially if you’re already prone to thyroid problems.
  • Both menopause and thyroid problems are common occurrences for women in midlife, and their symptoms can sometimes overlap.
  • Having overlapping symptoms doesn’t necessarily mean you have both problems. But it’s important to get it checked for peace of mind and proper treatment.
  • With the right approach, it’s possible to maintain a healthy and active life during menopause and beyond. 
  • Managing menopause symptoms and thyroid health often requires a holistic approach, including hormone replacement therapy (HRT) for menopause symptoms and specific treatments for thyroid disorders


Early signs include fatigue, weight gain, mood swings, and changes in menstrual cycles. If these symptoms persist, it’s important to consult a healthcare provider.

Yes, certain thyroid disorders can lead to hormonal imbalances that may influence the timing of menopause and possibly trigger early menopause. Proper diagnosis and treatment are essential to manage these conditions.

Hypothyroidism is typically treated with synthetic thyroid hormone replacement. Levothyroxine is the most commonly prescribed thyroid hormone replacement drug. Its dosage is adjusted  based on regular monitoring of thyroid function.

It’s important to undergo medical testing to differentiate between the two. Blood tests for thyroid function and a thorough evaluation by a healthcare provider can help determine the cause of symptoms.

HRT may affect thyroid function in some cases, particularly for those already being treated for hypothyroidism. Oral estrogen can decrease active thyroid hormone, potentially requiring a medication dosage adjustment. However, this is unlikely to apply to those with normal thyroid function. If you have concerns, consult a healthcare professional.
