Thyroid Problems in Menopause: Is It Your Thyroid or Your Hormones?

As we journey through life, it’s not just our birthdays that keep adding up. Our body is keeping count too, especially when it comes to our health!

For many women, the aging process brings a delightful cocktail of wisdom and experience, but it can also stir up some unexpected challenges.

Suddenly, you might find yourself battling fatigue, mood swings or those stubborn pounds that seem to have taken up permanent residence. What could be the culprit? Could it be thyroid problems?

Oh, there can be many possible factors! But your thyroid is one that gets missed all the time, so let’s look at how it ties in with everything else that shifts in midlife. Because let’s face it, aging may throw us some curveballs, but with the right information, we can hit them out of the park!

Here’s the tricky part: thyroid problems are far more common in women than in men, and they get more common after 50. And the symptoms (tiredness, weight gain, low mood, feeling too hot or too cold, a racing heart) overlap almost perfectly with menopause. So it’s really easy to blame one for the other! Cleveland Clinic has a good read on how to tell menopause and thyroid trouble apart.

The Butterfly Gland: Thyroid’s Role in Women’s Health

Ladies, let’s talk about our little friend in the neck — the thyroid. This butterfly-shaped gland might be small, but it packs a powerful punch in our health, especially as we navigate the twists and turns of midlife.

If you’ve ever felt like your body is throwing a mini tantrum with unexpected energy dips, weight changes or mood swings, trust me, you’re in very good company. The thyroid is often the unsung hero (or sometimes the villain) behind this!

Let’s break down what this gland actually does and how it helps us shine in midlife:

• Metabolism Manager: It controls how efficiently your body converts food into energy. A happy thyroid means you can enjoy your meals without unexpected consequences!

• Mood Stabilizer: Keeps your mood swings in check; a well-functioning thyroid helps you feel more balanced and less like you’re on a rollercoaster ride!

• Energy Booster: Aids in weight management and keeps your energy levels high. With the right support, you’ll be able to keep up with daily tasks!

• Temperature Regulator: Helps regulate body temperature, so you’re not constantly battling chills or overheating (which can feel a lot like hot flashes!). Oh, hello, comfort!

• Heart Rate Keeper: Influences how fast or slow your heart beats; a balanced thyroid ensures your ticker is in good shape!

As we glide through midlife, our thyroid can sometimes become a little shaky due to hormonal changes. But fear not — there are many things we can do to keep this butterfly flying high!

By incorporating nourishing foods, prioritizing self-care and making informed lifestyle choices, we can nurture our thyroid health naturally. More about that as you read further!

Unmasking the Symptoms of Thyroid Problems in Women

This butterfly-shaped gland may be small, but when the thyroid is underperforming, it can cause a whirlwind of symptoms that are all too relatable! Among those are:

Fatigue/Low Energy: Ever feel like you’re dragging yourself through the day despite a full night’s sleep? That constant tiredness might point to an underactive thyroid.

Weight Fluctuations: If your scale seems to have a mind of its own, showing numbers you never thought you’d see, it could be your thyroid throwing a weight surprise party!

Mood Swings: Do your emotions feel like a rollercoaster? Yep, so many of us know that ride! Thyroid issues can cause unpredictable mood shifts, making you feel more out of sync than usual.

Hair and Skin Changes: Notice your hair thinning or your skin feeling unusually dry? Your thyroid could be a contributing factor, and that’s a bummer when you want to rock that crowning glory!

Changes in Sleep Patterns: Struggling to hit the hay or waking up in the middle of the night? Sleep disturbances could signal that your thyroid is out of tune.

Menstrual Irregularities: If Aunt Flo’s visits have become unpredictable, be it heavier periods, lighter ones or just downright absence, it’s time to think that your thyroid might be a mediating factor.

Cold Intolerance: Are you feeling chillier than your friends, even in warm weather? A sluggish thyroid might be to blame, leaving you reaching for extra layers!

Digestive Issues: Constipation can become more frequent when the thyroid is out of balance. And no one wants to feel bloated while trying to enjoy life, right?

Brain Fog: If you find yourself looking for your glasses… only to realize they’re on your head, or struggling to find the right words mid-conversation, it could be your thyroid playing tricks on your mind — a classic kind of brain fog!

Most of these point to an underactive thyroid. An overactive one looks quite different. More on that below!

If you recognize these signs, take a moment to check in with your healthcare professional and ask for a simple thyroid blood test (TSH). Thyroid problems are easy to check for, and easy to miss if nobody looks. Your thyroid deserves a spotlight, and with a little awareness and care, you can keep this tiny gland humming along smoothly for your well-being. Always listen to those whispers (or cries) of help from your body!

Why Midlife Women Are More Prone to Thyroid Problems

In midlife, our hormones can feel like they’re embarking on an adventurous road trip without a map. Estrogen and progesterone are the dynamic duo at the heart of this! Your adrenals may also join this wild ride of a journey.

Let’s get to know how these hormones affect your thyroid health in midlife, shall we?

Estrogen

Picture estrogen as that enthusiastic friend who sometimes just can’t help but take over the party. When estrogen runs high (during perimenopause swings, or when you take estrogen as a pill), your liver makes more thyroid-binding globulin. That’s a protein that carries thyroid hormone around and keeps it “parked”. So less free hormone is left for your body to use. A healthy thyroid usually just makes a bit more to keep up. But if you already take thyroid medicine, starting or stopping oral HRT can change how much you need. Ask for a TSH check a couple of months later. (Patches and gels hardly have this effect.)

Progesterone

Meanwhile, progesterone is like the calm voice trying to maintain balance in the middle of all the chaos. When progesterone drops in perimenopause, it doesn’t damage your thyroid. But it brings its own tiredness, restless nights and weight shifts, which look a lot like a sluggish thyroid. That’s exactly why the two are so easy to mix up!

Adrenal Hormones

The adrenal glands are responsible for producing our stress-regulating hormones — including cortisol, adrenaline (epinephrine), DHEA and more. But as we hit midlife, where things can be a dizzying mix of responsibilities, we tend to become more vulnerable to chronic stress. Yup, that constant, long-term kind of stress!

The problem is that chronic stress knocks your stress system out of rhythm. And when stress hormones stay high for too long, your body gets slower at turning T4 (the storage form of thyroid hormone) into T3 (the active form your cells actually use). Hello, fatigue, weight gain and brain fog! Calming your cortisol is one of the kindest things you can do for your thyroid.

Overactive Thyroid: What Causes Hyperthyroidism?

Now, onto hyperthyroidism… This condition happens when the thyroid gland gets so pumped up that it starts producing excess hormones — causing a whirlwind of activity in your body. Here are the usual suspects behind this hyper act:

Graves’ Disease: The most common cause by far. It’s an autoimmune condition, meaning your immune system flips the thyroid’s “on” switch too hard. It makes your thyroid rev its engines, leading to symptoms like unexpected weight loss and a racing heart.

Stress: Ah, stress — that uninvited guest we all know too well. Stress can’t cause hyperthyroidism on its own. But a big, tough stretch of life can trigger Graves’ or make it flare in women who are already prone to it.

Thyroid Nodules: While most nodules are harmless, some decide they want to join the hormone-production game, pushing your thyroid into overdrive.

Too Much Iodine or Thyroid Medicine: High-dose iodine (like kelp tablets or iodine drops) or a thyroid medicine dose that’s set too high can push your levels up, too.

Signs to watch for: a racing or pounding heart, feeling hot and sweaty, shaky hands, anxiety, poor sleep and weight loss without trying. Sound familiar? Many of these look just like menopause, which is one more reason to get tested.

Underactive Thyroid: What Causes Hypothyroidism?

On the other end of the spectrum lies hypothyroidism, where our little butterfly flops its wings and struggles to get off the ground. Here are some common culprits:

Iodine Deficiency: Your thyroid needs iodine to make its hormones. Not getting enough over time (from seafood, dairy, eggs or iodized salt) can leave it fumbling. It’s less common in places that use iodized salt, but it still happens. Just think of it as your thyroid’s tech toolkit missing a crucial gadget!

Autoimmune Disorders: Enter Hashimoto’s thyroiditis — the sneaky ninja of the thyroid world. This autoimmune condition quietly attacks the gland, leading to a decrease in hormone production. It’s the most common cause of an underactive thyroid in countries like the US and UK, and it’s much more common in women, especially after 40. With this condition, many women find themselves wondering why they’re suddenly feeling less like themselves.

Medications: Some medications have a knack for playing hard to get when it comes to hormone production. Certain heart medications (like amiodarone) and lithium can meddle with thyroid function, leaving you feeling out of sorts!

7 Ways to Support Your Thyroid in Midlife

Picture this: Each day, you start with a set amount of energy, almost like money in your bank account. As a midlife woman dealing with various symptoms (thyroid problems or not), managing this energy budget is crucial for your thyroid!

By doing so, you can keep your body’s account in the black, ensuring you feel your best each day. So, if you feel like your energy account’s empty, try to focus on what has been draining it and take some of these steps for your butterfly gland!

Manage Stress, Keep It Low!

There’s daily stress from our usual stressors, like responsibilities, relationships, work and so on. And then there’s hidden stress that you may not think about as often: Not eating enough, not eating right, not getting enough sleep, sedentary lifestyle, too much exercise, alcohol and whatnot.

Every activity you do withdraws from your energy account! If you overspend, your balance dips into the red, leaving you feeling drained and out of balance. So, just like a financial budget, it’s important to plan and prioritize where you spend your energy!

Recovery is Key!

Being in nature, mindfulness, breathing techniques are my must-haves in midlife. Does any of these sound like zen to you?

Remember, recharging or replenishing your energy account is essential! That could also be getting enough sleep, eating nourishing foods or simply taking time for your kind of relaxation. I mean, our “recharge plans” are unique, some of us find solace in yoga, while others recharge in other ways. Whatever best suits your style, do more of it!

Maintain Gut Balance!

Our gut health plays a vital role in hormone regulation and overall well-being. A balanced gut can reduce inflammation, support better thyroid function and help you absorb those essential nutrients!

Focus on consuming probiotics found in yogurt, kefir and fermented foods, as well as prebiotic foods like garlic, onions and bananas to nourish the good bacteria in your gut!

Oh, and if you didn’t know already, the gut also holds a massive amount of your innate immunity. And if that isn’t enough bragging, your gut is a powerhouse too for producing some of your feel-good hormones! Enough reason to look after it, I hope? wink

More Thyroid-Nourishing Foods Please!

Food is fuel. You’ve probably heard that many times somewhere else, but I will repeat it. What you eat has a profound impact on your thyroid and overall health!

Some of the thyroid-nourishing foods you can add into your meals are foods rich in iodine, selenium, and zinc. Think seafood, eggs and dairy for iodine, just 1–2 Brazil nuts a day for selenium, and pumpkin seeds for zinc. Seaweed is fine now and then, but kelp is so packed with iodine that a little goes a long way! Conversely, avoid processed foods and excessive sugar as they can lead to inflammation and hormonal imbalances.

Detox, Clear Out Some Weeds!

Just like a garden needs weeding, our body also needs detox. Your liver and kidneys do the real detox work. You can make their job easier by cutting down on toxins in your home and on your plate, eating whole (ideally organic) foods and staying hydrated! Consider incorporating detoxifying foods like leafy greens, cruciferous vegetables and berries. (And no, you don’t need to fear broccoli or kale. Cooked and in normal amounts, they’re just fine for your thyroid.)

And you know what? My course FAST.EAT.THRIVE!™ can guide you step-by-step on a healthier lifestyle that detoxifies, renews and resets your body during the midlife transition.

Herbs

Herbs, like Ashwagandha, and adaptogens can be wonderful allies for your thyroid health. They help with stress management, promote hormonal balance and support overall vitality! Incorporating them into your routine can also assist your body in adapting to stressors — enhancing both mental well-being and energy levels.

One heads-up: ashwagandha can nudge thyroid hormone levels up. So skip it if you have an overactive thyroid, and check with your doctor first if you take thyroid medicine. NCCIH has a clear page on ashwagandha safety.

Supplements

Supplements can make a difference when it comes to thyroid support. Ensure you’re getting enough selenium, zinc, B vitamins, magnesium and vitamin D with K2. These key nutrients all play a part in keeping your thyroid working well!

A few friendly warnings, though. Iodine is the tricky one: only take it as a supplement if a health professional has checked that you need it. Too much can harm the thyroid, especially if you have Hashimoto’s. The same goes for selenium, where more isn’t better. And if you take biotin (it’s in lots of hair, skin and nail supplements), stop it a few days before a thyroid blood test, because it can throw off the results.

Taking steps to nurture your thyroid health can empower you to manage your energy budget effectively, helping you feel vibrant and supported through midlife and beyond!

Beyond the Basics: Understanding Thyroid Tests

Now, if you deem it wise to go beyond the basics and the natural ways we’ve mentioned, I’m also for regular check-ups and blood tests. They provide insights into your hormone levels — helping catch thyroid problems early and guiding us toward a healthier lifestyle! After all, who wouldn’t want to dance through life with the wings of a well-functioning thyroid?

When it comes to assessing thyroid health, it’s important to go beyond the standard “thyroid stimulating hormone” or TSH test.

What should we go for instead? Well, a thorough evaluation involves a complete thyroid panel that provides a more comprehensive view of how your thyroid is functioning!

Why the Whole Panel Matters

A full thyroid panel, which includes TSH, free T4, free T3 and thyroid antibodies, can provide a much clearer picture of what’s happening within your thyroid.

By evaluating TSH and T4 together, you’ll know whether your thyroid is functioning optimally or if there are potential and other underlying issues that need addressing.

This helps you and your healthcare provider get to more effective management, whether through lifestyle changes, medication or other interventions!

Here’s a breakdown of the essential thyroid tests and why each is important:

TSH (Thyroid-Stimulating Hormone) Test

TSH is produced by the pituitary gland to signal your thyroid to produce thyroid hormones (T3 and T4). If your thyroid isn’t producing enough hormones, your pituitary gland releases more TSH to compensate. So, a high TSH level suggests hypothyroidism (underactive thyroid), while a low TSH level suggests hyperthyroidism (overactive thyroid).

→ Normal range: Generally, the normal range is between 0.4 and 4.0 mIU/L, but some experts suggest aiming for a TSH closer to 1.0 mIU/L for optimal thyroid function.

→ Functional Medicine Optimal Range: 1.0 to 2.0 mIU/L

✅ Why Go for Optimal: A TSH level in this range is generally considered optimal for overall thyroid function, as it reflects a healthy balance between the pituitary gland and the thyroid. Functional medicine doctors suggest that levels higher than 2.0 mIU/L could indicate suboptimal thyroid function, even if they fall within the conventional “normal” range.

A quick, honest note: these “optimal” ranges come from functional medicine. They’re not official, and your TSH naturally drifts up a little as you get older. So use them as a talking point with your doctor, not as a do-it-yourself diagnosis.

Free T4 (Thyroxine) Test

T4 is the main hormone produced by the thyroid. While most of it is bound to proteins, the free T4 (unbound) is the active form that your body can use. Low levels of free T4 can indicate hypothyroidism.

→ Normal range: The typical reference range for free T4 is around 0.8 to 2.0 ng/dL, but this can vary slightly based on the laboratory.

→ Functional Medicine Optimal Range: 1.0 to 1.8 ng/dL

✅ Why Go for Optimal: Functional medicine practitioners focus on ensuring that free T4 is within a more ideal range, as it directly impacts energy levels and metabolism. Low T4 could indicate insufficient thyroid function, even if other markers are in normal ranges.

Free T3 (Triiodothyronine) Test

T3 is the active thyroid hormone that your cells use. While most T3 is converted from T4 in your body, testing free T3 gives insight into how much of the active form is available. Low T3 levels can indicate thyroid issues, even if TSH and T4 seem normal.

→ Normal range: Free T3 levels generally range from 2.3 to 4.2 pg/mL.

→ Functional Medicine Optimal Range: 3.2 to 4.2 pg/mL

✅ Why Go for Optimal: Having Free T3 within the optimal range is essential for feeling energized and maintaining healthy metabolism. Functional medicine doctors want to ensure that T3 levels are sufficient for proper cellular function.

Thyroid Antibodies (TPOAb and TgAb) Test

This test checks for the presence of antibodies that can attack your thyroid, a hallmark of autoimmune thyroid diseases like Hashimoto’s thyroiditis (which causes hypothyroidism) or Graves’ disease (which causes hyperthyroidism).

→ TPO (Thyroid Peroxidase) Antibodies: Elevated levels can indicate Hashimoto’s thyroiditis or autoimmune thyroid disease.

→ Tg (Thyroglobulin) Antibodies: Elevated levels may also point to autoimmune thyroid conditions.

If your thyroid is under attack by your immune system, it may not function properly. In other words, if you have symptoms of hypothyroidism or hyperthyroidism and regular thyroid function tests (TSH, T4, T3) are normal, thyroid antibodies can help identify an autoimmune cause.

✅ Functional Medicine Optimal Range: < 35 IU/mL (for both TPO and Tg antibodies)

Reverse T3 (rT3) Test (optional)

Reverse T3 is an inactive form of T3. If you’re under stress or dealing with chronic illness, your body can produce more reverse T3, which can block the effects of active T3. This test can be helpful in cases where your symptoms suggest hypothyroidism, but other tests (like TSH) are normal.

→ Normal range: The typical reference range for reverse T3 is around 9 to 27 ng/dL.

→ Functional Medicine Optimal Range: 10 to 24 ng/dL

Just so you know, many regular doctors don’t find this test very useful, so don’t be surprised if yours says no. A functional medicine practitioner is more likely to order it.

Ultrasound or Imaging (if needed)

If blood tests suggest thyroid issues, an ultrasound or other imaging may be used to check for structural problems like nodules or goiter (enlargement of the thyroid gland). This is especially useful if there are symptoms like a visible swelling in the neck or difficulty swallowing.

To sum up, if you’re getting thyroid tests done through a functional medicine practitioner, they’ll likely interpret results based on the optimal ranges AND consider how you’re feeling — not just your test numbers.

By aiming for optimal rather than just “normal” ranges, functional medicine doctors work to prevent long-term thyroid dysfunction and support overall wellness! They look at the underlying causes of thyroid issues (such as stress, nutrient gaps or autoimmune conditions). And if your thyroid can’t make enough hormone on its own, medicine isn’t “masking” anything. It simply replaces what’s missing! So if you’re on thyroid medicine, never stop or change it on your own. Talk to your doctor first.

Quick Inventory: Why Your Emotional Well-Being Matters

Many of us carry emotional backpacks, especially through the menopause transition. At this phase of life, it becomes vital to take stock of what’s inside our backpack!

Emotional well-being and thyroid health are closely tied, and it works both ways. An underactive thyroid can drag your mood down, and long-term stress puts extra strain on your whole hormone system, thyroid included.

Consider your relationships: Are they healthy and supportive? Or do they weigh you down?

If you find it hard to drop or release the emotional baggage you’re carrying, it might just be time for a little inventory! Identify the elements of your life that deplete your energy — whether they are toxic relationships, unfulfilling work or negative self-talk. By removing these, you can create space for positivity and empowerment!

After all, as we age, our hormones begin to fluctuate significantly, impacting not only our physical health but also our emotional state and mental well-being. So, just as we allowed ourselves the grace of youth, we must be gentle with ourselves now!

By nurturing our thyroid health and taking charge of our emotional well-being, we empower ourselves to embrace this chapter with clarity and joy. And if thyroid problems are part of your story, you now know what to look for and what to ask. Let’s lighten that backpack and soar into a brighter, more fulfilling life!

FAQs About Thyroid Problems in Menopause

Can menopause cause thyroid problems?

Menopause doesn’t cause thyroid disease. But both tend to show up at the same time of life, and thyroid problems (especially Hashimoto’s) get more common with age. Shifting estrogen can also change how thyroid hormone is carried in your blood.

How do I know if it’s my thyroid or menopause?

The truth? You can’t tell by symptoms alone, because they overlap so much. A simple blood test (TSH, ideally with free T4) is the way to find out. And it’s totally possible to have both!

Can HRT affect my thyroid medicine?

It can. Estrogen taken as a pill may raise how much thyroid medicine you need, while patches and gels hardly do. Ask for a TSH check a couple of months after starting or stopping HRT.

Should I take iodine for my thyroid?

Not unless a health professional has tested you and says you need it. Food first: seafood, eggs, dairy and iodized salt. Too much iodine can harm the thyroid, especially if you have Hashimoto’s.
