Menopause and thyroid disease can cause similar symptoms. Both conditions can disrupt sleep, mood, weight, and energy.1,2 When they occur at the same time, symptoms may be mistakenly attributed to one condition when both need attention.1 Understanding how menopause and thyroid disease interact is an important first step toward getting the right diagnosis and the right care. 

What is menopause, and what does it feel like? 

Natural menopause is defined as the absence of menstrual periods for at least 12 months and typically occurs around age 51 in Europe.3 The years leading up to this point, called perimenopause, involve a gradual fall in oestrogen levels, irregular periods, and a range of physical and emotional symptoms. This transition can last two to four years.3 When menopause occurs before age 40, it is called premature ovarian insufficiency (POI).3 

What are the most common symptoms? 

The most common symptoms of menopause include hot flushes, night sweats, low mood, sleep disturbances, vaginal dryness, joint discomfort, and anxiety.1,3 These symptoms vary widely between women in their nature and severity. Because many are non-specific, they can easily be confused with those of other conditions, most notably thyroid disease.1,2 

Can thyroid disease cause symptoms that are similar to menopause? 

Yes. Thyroid disease and menopause share many of the same symptoms, making it genuinely difficult to tell the two conditions apart. 

Which symptoms do they share? 

Both hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid) may overlap with symptoms of menopause.1 Shared symptoms include menstrual irregularities, mood disorders such as anxiety and depression, hair loss, reduced sex drive, and a general decline in quality of life.1,2 Sleep disturbances are particularly associated with hyperthyroidism, which can cause insomnia that may overlap with perimenopause-related sleep problems.1 

Hyperthyroidism, in particular, can cause increased sweating and tremor symptoms that may be confused with hot flushes.1,2 

Hypothyroidism may lead to weight gain, fatigue, and low mood symptoms also commonly reported during the menopausal transition.2,3 Cold intolerance is a recognized feature of hypothyroidism, but is not a typical symptom of menopause; its presence alongside other overlapping symptoms may help guide clinical investigation.2 

Are there signs that help tell the two conditions apart? 

Some signs are more specific to thyroid disease, such as a visible enlargement of the thyroid gland (goitre), eye changes associated with Graves’ disease, or pronounced cold intolerance.1,2 However, these signs are not always present, especially in early or mild thyroid dysfunction, making laboratory testing essential.1,2 

Why does this overlap lead to delayed diagnosis? 

Without distinct signs pointing clearly to one condition, symptoms may be attributed to menopause when thyroid disease is also present.1 This can result in delayed diagnosis and unnecessary suffering. Healthcare professionals who work with midlife women are encouraged to maintain a low threshold of suspicion for thyroid testing when menopause-like symptoms are present.1 

Can menopause trigger or worsen thyroid problems? 

The menopausal transition may be associated with several changes in thyroid health, including a higher risk of thyroid nodules, an influence on thyroid cancer risk, and a possible worsening of autoimmune thyroid conditions. 

Does menopause affect the risk of thyroid nodules or thyroid cancer? 

The incidence of thyroid nodules increases with age, and more markedly in women than in men.1 

Natural menopause appears to be associated with a decreased incidence of thyroid cancer whereas, surgical menopause is associated with an increased risk of thyroid cancer.1 

Early menarche (first menstrual cycle of a teenager) and late natural menopause have also been linked to thyroid cancer, suggesting that the overall duration of oestrogen exposure may play a role.1 

Women with a history of surgical menopause, early menarche, or late natural menopause may benefit from thyroid evaluation as part of their ongoing care.1 

How does menopause interact with autoimmune thyroid conditions? 

Autoimmune thyroid conditions, such as Hashimoto’s thyroiditis, are among the most common endocrine disorders in women with premature ovarian insufficiency (POI).4 Subclinical hypothyroidism, often caused by autoimmune thyroiditis, affects 6 to 10% of women and frequently arises or continues during the menopausal transition.1 

Thyroid autoimmunity is also significantly more prevalent in women with premature ovarian insufficiency.4 The precise mechanisms behind this association are still being investigated, and evidence in this specific area remains limited. 

Can the combination of menopause and thyroid dysfunction affect metabolic health? 

Both menopause and thyroid disease can independently affect metabolism and together, their effects may be compounded. Low thyroid hormone levels have been associated with insulin resistance, an association that appears more pronounced in postmenopausal women.1 

Subclinical hypothyroidism has been associated with elevated cholesterol levels and increased cardiovascular risk.1 Non-alcoholic fatty liver disease (NAFLD) also becomes more prevalent after menopause, and evidence suggests that thyroid hormone levels may contribute alongside other hormonal and metabolic changes; however, this relationship is part of a broader metabolic picture and should not be attributed solely to subclinical hypothyroidism.1 

Clinicians are encouraged to assess lipid levels in women with both thyroid dysfunction and menopausal status.1 

Should thyroid function be checked in women experiencing menopause symptoms? 

Yes. Thyroid testing is recommended for midlife women, particularly those with symptoms that could be related to thyroid dysfunction. 

Who should be tested, and how often? 

The American Thyroid Association recommends that all adults have their thyroid-stimulating hormone (TSH) level measured starting at age 35, and every five years thereafter.2 This recommendation is especially important in women, who have a higher prevalence of thyroid dysfunction.2 Those with risk factors, including a personal or family history of thyroid disease, diabetes, or pernicious anemia and adrenal insufficiency, may require more frequent testing.2 

What does a thyroid test involve? 

A blood test measuring TSH is the single most reliable way to detect the most common forms of hypothyroidism and hyperthyroidism.2 If TSH levels are abnormal, serum FT4 measurement and serum triiodothyronine(T3) assay in patients with a normal serum FT4 level are indicated to further assess patients.2 This is a safe, widely available, and relatively low-cost test.2 

Can common supplements interfere with thyroid test results? 

Yes, and this is an important, often overlooked issue. Many women going through menopause take biotin (vitamin B7) supplements for hair or skin concerns.1 Biotin can interfere with thyroid immunoassays and lead to falsely abnormal results, either falsely low or falsely high, depending on the type of test used.1 Women taking biotin-containing supplements should stop them two to three days before any thyroid blood test and always inform their healthcare provider about all supplements they are taking.1 

Why is it important to talk to a doctor rather than self-diagnose? 

The overlap between menopause and thyroid disease is real, and navigating it safely requires professional assessment. 

Symptoms such as fatigue, mood changes, hair loss, sleep disturbances, and weight shifts can have many causes.1,2 Assuming these symptoms are “just menopause” without clinical evaluation risks missing a treatable thyroid condition and the reverse is equally true. A blood test is the only reliable way to confirm or rule out thyroid dysfunction.2 

A personalised approach is always recommended. Clinical decisions should take into account a woman’s full medical and family history, her specific symptoms, and her individual preferences and should always be made in partnership with a qualified healthcare professional.1 If you are experiencing symptoms that concern you, speaking with your doctor is the most important first step. 

Conclusion 

Menopause and thyroid disease share many symptoms, making diagnosis more complex than it might first appear. The menopausal transition may also influence thyroid health in several ways from changes in thyroid nodule risk to interactions with autoimmune thyroid conditions and metabolic function. Thyroid screening is recommended for all adults from age 35, and awareness of factors like biotin supplementation can improve test accuracy. If you are unsure whether your symptoms could be related to your thyroid, a conversation with your healthcare team is always the right place to start. 

FAQ

1. Can menopause and thyroid disease occur at the same time? 

Yes. Menopause and thyroid disease can and frequently do occur together. Both conditions are common in women during midlife, and their overlapping symptoms may complicate diagnosis.1 A blood test measuring TSH is the most reliable way to identify thyroid dysfunction.2 

2. How can I tell if my symptoms are from menopause or thyroid disease? 

It can be difficult to tell the two conditions apart based on symptoms alone, as they share many of the same signs, including mood changes, fatigue, hair loss, and menstrual irregularities; sleep disturbances are more specifically associated with hyperthyroidism.1,2 Symptoms more specific to thyroid disease, such as a goitre, eye changes associated with Graves’ disease, or marked cold intolerance, may be absent in mild cases.1 A thyroid blood test is the only reliable way to differentiate between the two.2 

3. At what age should women start getting thyroid tests? 

The American Thyroid Association recommends that all adults begin thyroid screening at age 35, with tests repeated every five years.2 Women with risk factors, including a family history of thyroid disease, autoimmune conditions, or diabetes, may need earlier or more frequent testing.2 This recommendation is considered especially important in women.2 

4. What is the most accurate test for thyroid function? 

A blood test measuring thyroid-stimulating hormone (TSH) is the single most reliable test for detecting common forms of hypothyroidism and hyperthyroidism.2 If TSH levels are abnormal, serum FT4 measurement and serum triiodothyronine(T3) assay in patients with a normal serum FT4 level are indicated to further assess patients.2 This test is safe, widely available, and relatively low-cost.2 

5. Can biotin supplements really affect thyroid test results? 

Yes. Biotin (vitamin B7), commonly found in hair and skin supplements, can interfere with thyroid immunoassays and produce falsely abnormal results.1 Biotin can cause falsely low results in some tests and falsely high results in others, depending on the assay type.1 Women taking biotin supplements should stop them two to three days before a thyroid blood test and inform their healthcare provider.1 

6. Does thyroid dysfunction affect cholesterol or cardiovascular risk during menopause? 

Subclinical hypothyroidism has been associated with elevated triglyceride levels, higher total cholesterol, and increased cardiovascular risk.1 These metabolic effects appear more pronounced in postmenopausal women, suggesting a compounding effect of thyroid dysfunction and oestrogen decline.1 Clinicians are advised to assess lipid levels in women with both menopausal status and thyroid dysfunction.1 

7. Is autoimmune thyroid disease more common in women with premature ovarian insufficiency? 

Yes. Thyroid autoimmunity is significantly more prevalent in women with premature ovarian insufficiency.4 A broader immune dysregulation is thought to contribute to both conditions, though the precise mechanisms are not fully understood.4 Women diagnosed with POI may benefit from screening for autoimmune thyroid conditions.1
