Have you snapped at a loved one for no reason and then dissolved into tears over a cute dog TikTok? If so, welcome to the estrogen fluctuation club, membership begins somewhere in your late 30’s and often without warning.

What Are Estrogen Fluctuations and Why Do They Matter?
The Basics
Estrogen is actually a group of hormones, with estradiol being the most potent. It’s the multitasking queen that regulates your menstrual cycle, supports bone and heart health, influences your mood, boosts skin elasticity, and even impacts brain function.
Estrogen fluctuations refer to the erratic rise and fall of estrogen levels during perimenopause, (the transitional phase leading up to the menopause) Remember the menopause is defined as 12 months without a period. This phase can last 3 to 10 years. While menopause typically arrives around age 51, perimenopausal symptoms can start in your late 30s.
Why It’s a Big Deal
These hormonal shifts affect nearly every system in your body. One month you’re feeling normal; the next, you’re battling hot flushes, brain fog, or mood swings that leave you wondering if you’re losing it. As estrogen levels decline, it impacts fat distribution (hello, belly fat), skin texture, memory, and more.
Myth Busting
- Myth: Menopause symptoms only start after age 50.
Truth: Many women begin experiencing perimenopausal symptoms in their late 30s or early 40s. - Myth: Hot flushes are the only sign.
Truth: Mood changes, fatigue, anxiety, and sleep issues are just as common.
Why You Need to Pay Attention
Low estrogen post-menopause is linked to increased risk of:
- Osteoporosis
- Heart disease
- Alzheimer’s
So no, you don’t have to suffer through this silently. Understanding estrogen fluctuations is key to protecting your long-term health.

The Science Behind Estrogen Fluctuations
A Peek Inside Your Hormonal Orchestra
Estrogen is produced by your ovaries and regulated by the pituitary gland via follicle-stimulating hormone (FSH) and luteinizing hormone (LH). As you age, your ovarian reserve diminishes. Your ovaries don’t respond as efficiently to FSH, leading to erratic estrogen production, sometimes spiking, sometimes plummeting.
What That Means for Your Body
- Brain: Estrogen supports neurotransmitters like serotonin and dopamine. When it drops, you may feel anxious, moody, or mentally foggy.
- Muscles & Bones: Estrogen maintains muscle mass and bone density. Without it, you lose muscle faster and your risk for osteoporosis increases.
- Heart: Estrogen helps keep arteries flexible and cholesterol in check. Its decline contributes to higher heart disease risk.
- Skin: Estrogen boosts collagen and hydration. Its fall leads to dryness, thinning, and more wrinkles.

What the Research Says
- JAMA Psychiatry (2015): Estradiol fluctuations linked to depression in perimenopausal women.
- NAMS Journal (2022): Vasomotor symptoms like hot flushes affect up to 75% of women in perimenopause.
- NICE Guidelines: HRT is safe and effective for most women when initiated under age 60
Common Challenges Women Face
1. The Symptom Lottery
You might feel great for weeks, then suddenly get slammed with symptoms. Heavy periods, sleepless nights, anxiety, night sweats, all appearing without rhyme or reason.
2. Body Image Disruption
You’re eating the same and working out more but gaining weight? Especially around the belly? It’s not in your head, estrogen loss affects fat storage and muscle mass.
3. Mood Swings & Mental Fog
Many women describe feeling like a stranger in their own mind. Forgetfulness, irritability, and emotional sensitivity peak. Between 45–55 is the highest risk period for depression in women.
4. Sleep Wreckage
“Wired but tired” becomes the new normal. Night sweats and restless sleep mess with your recovery and mood.
5. Relationships and Work Impact
Whether it’s intimacy issues or lack of concentration at work, these changes ripple through your whole life.
Practical Solutions & Strategies
Strategy #1: Nutrition Tweaks for Hormonal Balance
How it Works: Food can soothe or spike your hormones. The right choices help manage blood sugar, cortisol, and inflammation.
Implementation:
- Prioritize protein (20–30g per meal)
- Eat healthy fats: omega-3s (salmon, flax, walnuts)
- Add fibre + phytonutrients (especially cruciferous veg -think broccoli, cauliflower )
- Avoid processed and high-sugar foods
- Stay hydrated
Bonus: Use our “Estrogen Symptom Tracker” (free download) to log how food affects your symptoms.
Strategy #2: Exercise That Supports Your Hormones
How it Works: Movement boosts estrogen sensitivity, builds muscle, and lifts mood.
Implementation:
- 2–3x/week strength training (bands, weights, or bodyweight)
- 150 mins of moderate cardio per week
- Yoga or Pilates to calm the nervous system
- Move daily, even walks count!
Note: Strength training is especially key. It builds muscle, which burns more fat and improves insulin sensitivity. Read our guide on exercise.
Strategy #3: Sleep & Stress Mastery
How it Works: Chronic stress raises cortisol, which disrupts estrogen and worsens symptoms.
Implementation:
- Create a calming evening routine (no screens, warm baths)
- Practice 10 min daily mindfulness (apps like Calm or Insight Timer)
- Try magnesium glycinate or valerian root (check with GP first)
- Keep your bedroom cool, dark, and tech-free
Results: Better mood, fewer cravings, and a sharper brain.
Strategy #4: Explore Hormone Replacement Therapy (HRT)
How it Works: Replaces declining estrogen and progesterone to ease symptoms.
Quick Facts:
- Most effective relief for hot flushes, sleep, mood, and bone protection
- Safer than previously thought, especially when started within 10 years of menopause
- Available in patches, gels, or pills
When to Seek It: If symptoms are affecting your quality of life.
Check with: A menopause-savvy GP or specialist

FAQ
Am I too young for perimenopause?
Not necessarily. While the average age of menopause is 51, perimenopause, the transition leading up to it where estrogen starts its unpredictable dance, can begin for some women in their late 30s, though it’s more common in the early to mid-40s. Symptoms like changes in your menstrual cycle, new-onset mood swings, sleep disturbances, or unexplained fatigue, even in your late 30s, could be early signs of hormonal shifts. The podcast summary clearly states that perimenopausal symptoms can start even earlier than the common 35-50 age range, sometimes in the 30s. It’s worth tracking your symptoms and discussing them with a knowledgeable healthcare provider.
Why am I gaining weight despite doing everything right?
It’s a very common experience, and yes, fluctuating and ultimately declining estrogen plays a significant role. Estrogen influences fat storage and muscle mass. As estrogen levels drop, the body tends to store more fat viscerally (around the abdomen), and muscle mass can decrease, which slows metabolism. The podcast summary details this, noting fat migration to the abdominal area. However, “inevitable” doesn’t mean “unmanageable.” While it might be more challenging to maintain your previous body composition, targeted strategies like consistent strength training to build muscle, a diet rich in protein and whole foods, and managing stress (which can influence cortisol and fat storage) can make a significant difference.
Is HRT dangerous?
This is a very common and understandable concern due to past controversies. However, Dr. Jessica Shepard emphasizes, much of the fear around HRT stemmed from “junk science” that has since been largely disproven or put into proper context. For the vast majority of healthy women experiencing bothersome menopausal symptoms, especially those who start HRT within 10 years of menopause or before the age of 60, current medical consensus is that the benefits (like relief from hot flashes, night sweats, improved sleep, mood, and protection against osteoporosis, dementia, and heart disease) often outweigh the risks. There are specific contraindications (like a personal history of hormone-receptor-positive breast cancer or significant blood clots). The key is a personalized discussion with a healthcare provider who is up-to-date on the latest research and can assess your individual situation, benefits, and risks.
