Metabolic Health Is Women’s Health: 5 Ways It Impacts You (and What To Do About It)

27 Sept

Why do I keep banging on about blood sugar balance? Because for women, it’s not just about sugar highs, afternoon crashes, or weight gain. It touches every stage of life — puberty, fertility, perimenopause, menopause, and beyond.

By our mid-40s, women are more likely than men to struggle with overweight or obesity, both of which are risk factors for metabolic imbalances. On top of that, impaired glucose control becomes more common as we age. This is partly down to genetics and the way women store fat, but it’s also about hormones — oestrogen and progesterone have a huge influence on how our bodies use and store energy, and their fluctuations make women uniquely vulnerable to insulin resistance.

That’s why so many women’s health issues — from PCOS to hot flushes, from stubborn weight gain to brain fog — have their roots in poor blood sugar control. Let’s break down the five biggest ways metabolic health impacts women’s health.

1. Body Composition & Weight

At the heart of metabolic health is insulin — our storage hormone. Here’s how it works:

When we eat, insulin helps our cells absorb glucose from the bloodstream and use it for energy.
If there’s more glucose than our cells need (think eating too much, too often, or relying heavily on refined carbs), insulin shifts the excess into storage — first as glycogen, then as fat.
When insulin levels are high all the time, the body never gets the signal to switch into “fat burning mode.”

This is why many women struggle with stubborn weight gain, especially around the midsection, even when “eating healthy” or exercising.

Now add in menopause. Oestrogen normally helps our cells stay sensitive to insulin, but as levels drop, insulin resistance increases. This loss of hormonal protection is linked to rising visceral fat, higher cholesterol, and the onset of metabolic syndrome.

It’s not just a matter of aesthetics — these changes in body composition increase risks for cardiovascular disease, type 2 diabetes, and inflammatory conditions.

What You Can Do: Focus on meals that promote stable glucose: protein-rich foods, fibre, and healthy fats. This helps regulate insulin, allowing the body to dip into stored energy instead of staying stuck in “storage mode.”

2. Menopausal Symptoms (Hello Hot Flushes!)

Hot flushes and night sweats are often chalked up to “just hormones,” but blood sugar plays a starring role too. Research shows women with insulin resistance or type 2 diabetes experience more severe vasomotor symptoms.

Here’s why: fluctuating blood sugar levels affect how blood vessels dilate and constrict. Add hormonal shifts into the mix, and you’ve got the recipe for those intense temperature swings.

But the ripple effect doesn’t stop there:

Hot flushes disrupt sleep.
Poor sleep reduces the body’s ability to process glucose effectively.
Impaired glucose control worsens hot flushes.

It’s a vicious cycle.

What You Can Do: Track your food and symptoms — you might notice certain meals precede worse hot flushes. Reducing refined carbs and focusing on low-glycaemic foods can help. And if sleep is an issue, tackling both diet and sleep hygiene is essential. (P.S. This is exactly why I run my drop-in Sleep Smarter Clinics!)

3. Reproductive Health & Fertility

Metabolic health is tightly bound to reproductive health. A prime example is PCOS, the leading cause of infertility in women. Around 70% of women with PCOS show signs of insulin resistance.

Here’s how it works:

Excess insulin stimulates ovarian theca cells, causing them to produce more androgens (like testosterone).
This disrupts ovulation and leads to classic PCOS symptoms: irregular periods, excess hair growth, acne, and infertility.

The story doesn’t end there. Even women without PCOS experience blood sugar shifts across the menstrual cycle:

Follicular phase (first half): Higher insulin sensitivity, thanks to oestrogen.
Luteal phase (second half): Progesterone increases insulin resistance.

I saw this first-hand when I wore a Continuous Glucose Monitor for four weeks. The same meal gave me very different responses depending on which phase of my cycle I was in. In the luteal phase, I had to lean more on protein, healthy fats, and magnesium-rich foods while cutting back on carbs to keep my blood sugar stable.

What You Can Do: If you struggle with cycle symptoms or fertility challenges, consider your blood sugar balance. Tailoring diet to your cycle — especially reducing carbs in the luteal phase — can help smooth out hormonal shifts.

4. Brain & Cardiovascular Health

Here’s a sobering fact: women are twice as likely as men to develop dementia. And the disease process often begins 20–30 years before symptoms appear.

One of the biggest risk factors? Metabolic imbalance. Insulin resistance increases Alzheimer’s risk up to 10-fold.

The mechanisms are complex but boil down to this:

Poor glucose control leads to inflammation in the brain (neuroinflammation).
Excess glucose accelerates oxidative stress and damages blood vessels.
Proteins like beta-amyloid build up, triggering immune responses that fuel neurodegeneration.

This is why Alzheimer’s is sometimes called “Type 3 Diabetes.”

And it’s not just the brain. Repeated glucose spikes also harm cardiovascular health. Over time, they stiffen blood vessels, raise blood pressure, and increase the risk of arrhythmias like atrial fibrillation (AFib), which can lead to stroke and heart failure.

What You Can Do: Protect your brain and heart by keeping blood sugar steady. Balanced meals, stress management, and daily movement aren’t just “wellness hacks” — they’re disease prevention.

5. Skin Health

Metabolic health even shows up in your skin. Elevated glucose in the bloodstream can bind to proteins, fats, and DNA, creating Advanced Glycation End Products (AGEs).

When AGEs bind to collagen — the protein that gives skin its structure and elasticity — they alter its structure, making skin stiffer and less resilient. This speeds up visible ageing, dullness, and slower healing.

But it’s not only ageing: high-glycaemic diets also ramp up IGF-1 (insulin-like growth factor 1), which stimulates oil production in the skin. This is why excess sugar intake can fuel acne flare-ups.

What You Can Do: Think of stable blood sugar as part of your skincare routine. Eating low-glycaemic foods, plenty of antioxidants, and protein-rich meals helps keep collagen strong and your skin glowing.

The Bottom Line

Metabolic health is women’s health. From body composition and fertility to menopause, brain health, and even skin, blood sugar balance underpins it all.

Here’s a simple place to start:

Carbs to eat often: non-starchy veggies (spinach, broccoli, peppers, mushrooms, tomatoes) and low-sugar fruits (berries, grapefruit, kiwi).
Carbs to eat in moderation: starchy veggies (sweet potatoes, lentils, beans), higher-sugar fruits (bananas, grapes, mangoes), and whole grains.
Carbs to avoid: sodas, juices, sweeteners, flour-based products, and ultra-processed foods.

By prioritising whole, unprocessed foods and focusing on balance, you can support your energy, hormones, and long-term resilience.
