Menopause and Thyroid Health: Nirva Experts Explain Everything You Need to Know

The thyroid gland, a butterfly-shaped structure located in the neck, plays a crucial role in energy production, regulating metabolism and overall health. It produces thyroid hormones, triiodothyronine (T3) and thyroxine (T4), which influence nearly every cell in your body.

In particular, oestrogen (reproductive hormone) interacts with thyroid receptors, potentially influencing thyroid function. When you enter menopause, the balance between oestrogen and thyroid hormones gets disrupted, which leads to an increased risk of thyroid disorders, particularly hypothyroidism (underactive thyroid gland). 

Why Is Thyroid Health During Menopause a Health Concern?

As already discussed, hormonal imbalance during menopause can affect your thyroid function, leading to hyperthyroidism or hypothyroidism. Let's discuss each of these in detail:

Hyperthyroidism and Menopause

Hyperthyroidism involves an overactive thyroid gland, producing excessive thyroid hormones. Although less common than hypothyroidism, it can still occur during your menopause period and contribute to menopausal symptoms.

Symptoms of hyperthyroidism:

• Unintentional weight loss
• Rapid heartbeat and palpitations
• Tremors
• Anxiety and irritability
• Increased sweating
• Heat intolerance
• Bulging eyes (exophthalmos)

Hypothyroidism

Hypothyroidism, characterised by an underactive thyroid gland, is the most common thyroid disorder among women, with an increased prevalence during menopause. It occurs when your thyroid gland produces insufficient thyroid hormones, T3 and T4, leading to a slowdown in metabolism and various bodily functions.

Symptoms of hypothyroidism:

• Fatigue and lethargy
• Weight gain or difficulty losing weight
• Dry skin and hair
• Sensitivity to cold
• Difficulty concentrating
• Irregular menstrual cycles
• Mood swings and depression

Impact of Thyroid Disorders on Menopause

Both thyroid disorders, whether hypothyroidism or hyperthyroidism, can worsen your menopausal symptoms and increase the risk of complications. For instance, hypothyroidism can intensify fatigue, weight gain, and mood swings, while hyperthyroidism can amplify hot flashes, anxiety, and sleep disturbances.

Understanding the Hormonal Influences on Thyroid Function

Oestrogen and progesterone are the two important female sex hormones in your body that undergo significant changes during perimenopause and menopause. These hormonal fluctuations can influence thyroid function in many ways, leading to thyroid dysfunctions. Let's have a thorough look at its mechanism:

Oestrogen's Influence

Oestrogen in your body enhances the conversion of thyroid hormone T4 to a more active T3 form. Also, oestrogen promotes the transportation of thyroid hormones through the bloodstream. 

During perimenopause and menopause, declining oestrogen levels in your body affect the conversion of the T4 hormone to the T3 hormone, thus leading to a relative deficiency of the T3 hormone. This condition manifests as symptoms of hypothyroidism.

Progesterone's Influence

The exact mechanism of how progesterone influences your thyroid function has yet to be fully understood. But, many believe that progesterone has an inhibitory effect on thyroid functioning. The fluctuating levels of progesterone during perimenopause and menopause period lead to both overactivity and underactivity of the thyroid gland. The said process can lead to you experiencing symptoms of both hyperthyroidism and hypothyroidism during this period.

How to Recognise Thyroid Symptoms during Menopause?

Some of the general symptoms of thyroid dysfunctioning can coincide with that of menopause. These include fatigue, weight changes, mood swings and temperature sensitivity.

Here is a table summarising the typical symptoms of thyroid dysfunction that can coincide with menopause symptoms.

Thyroid Issues and Night Sweats: Decoding the Connection Between Them

One of the most common and disruptive symptoms you may experience during menopause is night sweats, sudden bouts of excessive sweating during sleep that can leave you drenched and uncomfortable during bedtime. Adding to the confusion, both hypothyroidism and hyperthyroidism can also contribute to night sweats, making it even more challenging.

Hypothyroidism and Night Sweats

Hypothyroidism can cause night sweats due to several factors:

Altered Temperature Regulation

Hypothyroidism leads to slow metabolism, leading to decreased body temperature. When you sleep, generally, the body temperature drops and your body fails to keep the optimum temperature. As compensation, the body triggers profuse sweating to raise the temperature.

Hormonal Imbalances

Regular production of thyroid hormones is essential to regulate your stress response. Decreased production of thyroid hormones can cause high sensitivity to stress, which can contribute to night sweats.

Disrupted Sleep Patterns

Due to hypothyroidism, you may experience increased fatigue and daytime sleepiness, both contributing to disturbed sleep at night. These disturbed sleep patterns increase the probability of experiencing night sweats at night.

Hyperthyroidism and Night Sweats

Hyperthyroidism can cause night sweats due to several factors:

Increased Metabolism

Hyperthyroidism can accelerate your metabolism rate, increasing body temperature. This elevated body temperature can trigger sweating during sleep as your body attempts to cool down.

Increased Heart Rate and Blood Flow

Hyperthyroidism can cause an increase in your heart rate and blood flow, leading to a feeling of excess warmth or even causing hot flashes. This increased heat production can contribute to night sweats.

Managing Night Sweats through Lifestyle Changes

Lifestyle modifications can help you manage night sweats and improve sleep quality in both hypothyroidism and hyperthyroidism. Here are some practical lifestyle modifications that you can follow:

Always Maintain a Cool Bedroom Environment: Keep your bedroom temperature cool and comfortable. Use lightweight, breathable bedding and avoid using heavy blankets or comforters that retain heat.

Dress in Light and Breathable Clothing: Wear loose-fitting, lightweight pyjamas from natural fibres like cotton or linen. Avoid synthetic fabrics that trap heat.

Avoid Triggers Before Bed: Avoid caffeine, alcohol, and spicy foods close to bedtime, as these can trigger sweating.

Using Lightweight Bedding: Opt for lightweight blankets and sheets that won't overheat you during the night. 

Managing Stress: Stress can exacerbate your night sweats, so finding healthy ways to manage stress is crucial. Stress management techniques could include exercise, relaxation techniques like yoga or meditation, or spending time in nature.

Maintaining a Healthy Weight: Excess weight can contribute to night sweats. If you're overweight or obese, losing weight can help to reduce your symptoms.

Regular Exercise: Regular physical activity helps regulate your body temperature and improve sleep quality, which can help reduce night sweats.

Thyroid Health Management During Menopause

Coping with hormonal fluctuations during menopause can be challenging for women. When thyroid health issues are also in the mix, managing changes can become even more difficult. With careful planning and lifestyle adjustments, you can effectively address this situation. Here's some practical advice on managing thyroid health while going through menopause:

Get a Regular Thyroid Function Test: It helps monitor your thyroid hormone levels and thus helps identify any potential thyroid issues early on.

Follow a Healthy Lifestyle: It is crucial for your overall well-being, and it's essential for thyroid health during menopause. A healthy lifestyle includes:

• Eating a balanced diet
• Following regular exercise
• Maintaining a healthy weight
• Managing stress

Seek Medical Attention: If you experience any symptoms of thyroid dysfunction, consult your healthcare professional. Early diagnosis and treatment can prevent complications.

Understand Medication Interactions: If you're taking thyroid medication, be aware of its interactions with other medications or supplements. Always consult with your doctor before starting any new medications or supplements.

The Key Takeaways

During menopause, paying attention to your thyroid health is essential since hormonal changes can impact its function. Knowing the link between hormones and thyroid health helps you catch any issues early and take action. Taking care of your thyroid health isn't just about managing symptoms but protecting your overall well-being. Visit your doctor regularly, lead a healthy lifestyle, and seek medical attention promptly to navigate this phase confidently.
