2 / Where to Start When Your Hormones Change During Perimenopause

You understand now what is happening during perimenopause. Ovulation becomes less predictable, progesterone production becomes inconsistent, estrogen can fluctuate dramatically and eventually settles at lower levels after menopause.

Knowing that explains a lot. But it doesn't help much when you haven't slept properly for six months, you're having hot flushes throughout the day, your period has become ridiculously heavy, you can't concentrate and you feel as though your previously reasonable personality has left the building.

So where do we start?

Not with a perfect menopause diet. Not with twelve supplements. And not with an enormous list of things you should be doing.

We start with whatever is making it hardest for you to function.

Step 1: Stabilise the symptoms that are disrupting your life during perimenopause

Before we talk about optimisation, identify your biggest problem.

If you are having severe night sweats and waking repeatedly, sleep deprivation may be driving some of the exhaustion, irritability, hunger, anxiety and brain fog you're experiencing during the day.

If bleeding has become extremely heavy, fatigue and weakness may not simply be "hormonal." Iron deficiency or anaemia may be contributing.

If anxiety or low mood has become severe, that deserves attention now rather than being placed at number seven on a menopause lifestyle checklist.

If vaginal pain means you are avoiding sex, that symptom deserves treatment even if everything else is relatively manageable.

This is the first question I would ask if you were sitting in front of me:

Which two or three symptoms are affecting your life the most?

Start there.

There is an important reason for this. Symptoms create secondary problems. Severe hot flushes can destroy sleep. Poor sleep can worsen mood, concentration, appetite regulation and glucose metabolism. Exhaustion can reduce activity and make food choices more difficult. Months of this can leave you feeling as though your entire body has stopped working when one major driver may be amplifying several other problems.

Sometimes improving the dominant symptom allows several others to improve with it.

Step 2: Fix sleep as early as possible

If your sleep is poor, I would move it very close to the top of the plan.

But "improve your sleep hygiene" isn't enough. We need to know why you are waking.

If hot flushes and night sweats repeatedly wake you, treating vasomotor symptoms is part of treating your sleep. A cool bedroom, breathable bedding, reducing individual triggers such as alcohol and avoiding overheating may help, but significant vasomotor symptoms may require proper treatment.

If you fall asleep easily and consistently wake several hours later, look at alcohol, caffeine, stress, medications, blood glucose issues where relevant and the timing of food and exercise.

If your mind starts racing the moment your head hits the pillow, we need to address anxiety and nervous system arousal rather than simply adding another sleep supplement.

And if you snore heavily, wake gasping, have morning headaches or remain exhausted despite apparently sleeping for long enough, consider sleep apnoea rather than assuming hormones are responsible.

This distinction matters because there is no single menopause sleep problem.

Treat what is actually disturbing the sleep.

Once sleep improves, many women notice that everything else feels slightly more manageable. Mood improves. Hunger and cravings can become easier to regulate. Energy improves. Exercise becomes possible again. Stress feels less overwhelming.

Sleep isn't a luxury we deal with once everything else is perfect. It is part of the treatment foundation.

Step 3: Take mood changes seriously

Perimenopause can affect mood. Hormonal fluctuations interact with brain systems involved in serotonin, dopamine, sleep and stress regulation, and some women experience new or worsening anxiety, irritability, low mood or emotional volatility during the menopause transition.

But "it's your hormones" should never be the end of the conversation.

First look at what may be feeding the problem. Severe sleep deprivation can profoundly affect emotional regulation. Alcohol can worsen sleep and mood. Chronic stress matters. So can thyroid dysfunction, iron deficiency, medication and existing mental health conditions.

If low mood, anxiety or irritability is mild, improving sleep, reducing alcohol, regular movement, adequate nutrition, daylight exposure, social connection and genuine recovery time can all help support the systems involved in mood regulation.

But significant depression or anxiety deserves proper treatment. If you no longer recognise yourself, are struggling to function or your mental health has deteriorated substantially, please don't spend six months trying magnesium and ashwagandha because somebody told you your cortisol is high.

Lifestyle support and medical or psychological treatment are not competing approaches.

Sometimes you need both.

Step 4: Make sure you are not running on empty

Once the most disruptive symptoms are being addressed, I want to look at whether your body actually has what it needs.

This is where nutrition enters the picture, but not as another menopause diet.

Women often respond to midlife body changes by progressively removing food. Less carbohydrate, less fat, smaller portions, longer fasting windows, more exercise.

At the same time, poor sleep and stress may already be increasing fatigue and reducing recovery.

I don't want your first nutrition question to be, "What should I cut out?"

I want it to be, "Am I actually nourishing this body properly?"

Protein matters because we need to preserve muscle and bone. Essential fats are necessary for normal physiology. Fibre supports gut and cardiometabolic health. Iron becomes particularly important if periods are heavy. Calcium, vitamin D, magnesium and other micronutrients matter for bone, muscle and nervous system function.

Build meals around real food and adequate nutrition rather than restriction. Include a meaningful protein source, vegetables and other plant foods, appropriate whole food carbohydrates and healthy fats.

If you regularly skip meals and then become ravenous in the evening, fix the eating pattern before deciding that your hormones have destroyed your metabolism.

And if you have heavy bleeding, significant fatigue, hair shedding, breathlessness or poor exercise tolerance, consider whether iron deficiency needs investigating rather than trying to solve exhaustion with caffeine.

Step 5: Reduce the things that amplify symptoms

Now we can start looking for individual amplifiers.

Alcohol is a good example. It doesn't "cause menopause," but it can worsen sleep and may trigger or intensify hot flushes in some women. If you suspect it is affecting you, don't debate the theory for three months. Reduce or remove it for a few weeks and observe what happens.

Caffeine may be completely fine for one woman and make another woman's palpitations, anxiety or sleep considerably worse.

Very spicy food triggers hot flushes in some women and does absolutely nothing to others.

Large meals late at night may worsen reflux or sleep for some women.

This is where I prefer experiments over rules.

Change one relevant variable for long enough to observe whether it makes a difference.

If it does, you have learned something useful about your body.

If it doesn't, stop creating restrictions you don't need.

Step 6: Help your nervous system recover

Perimenopause often arrives during one of the busiest stages of a woman's life. Work, relationships, teenagers or adult children, ageing parents, financial pressure and a body suddenly behaving differently can all be happening simultaneously.

Then we're told to "reduce stress," which is remarkably unhelpful when the stressful things cannot simply be removed.

What we can influence is recovery.

Your stress response is designed to activate and then settle. Problems arise when demand is almost constant and there is little opportunity for recovery.

This doesn't mean you need an hour of meditation every morning.

It might mean ten minutes outside after lunch. Walking without your phone. Yoga. Breathing exercises. Gardening. Reading. Music. Seeing people who make you feel better rather than worse. Saying no more often. Not answering messages at 11 pm.

Choose something that genuinely changes your physiological state rather than something else to tick off a wellness list.

And forget trying to "eliminate cortisol." Cortisol is an essential hormone. What we want is a healthy stress response, not the absence of one.

Step 7: Now rebuild strength and metabolic resilience

This is where resistance training belongs.

Not because it is unimportant. Quite the opposite. It is one of the most valuable long term interventions we have for women after menopause.

But if you are exhausted, severely symptomatic and barely sleeping, telling you to immediately begin an ambitious exercise programme is unlikely to help.

Once you have enough capacity, start building strength.

Ageing and menopause can contribute to loss of lean mass, while declining estrogen also affects bone. Resistance training provides a stimulus to preserve and build muscle and load bone. Muscle also plays an important role in glucose disposal and insulin sensitivity.

Aim eventually for regular resistance training that progressively challenges the major muscle groups, alongside walking and cardiovascular activity appropriate to your health and fitness.

But progression matters.

If you've been sedentary and exhausted for a year, your starting point may be walking for twenty minutes and doing a simple strength session twice a week.

If you're already fit, your programme should challenge you considerably more.

The goal isn't to burn off food.

It is to build a body that remains metabolically capable, strong and independent as you age.

Step 8: Protect the things you cannot feel changing

Once you're feeling more human again, we widen the lens.

Some of the most important consequences of menopause are silent.

You cannot feel bone density declining. You cannot necessarily feel your blood pressure rising. You may not notice insulin resistance developing or changes in cholesterol.

This is why menopause care should eventually include a broader midlife health assessment.

Know your blood pressure. Understand your glucose regulation and lipid profile. Consider your cardiovascular family history. Assess osteoporosis risk. Pay attention to waist circumference and body composition rather than simply weight.

If you smoke, stopping is one of the most powerful things you can do for cardiovascular and bone health. Keep alcohol moderate or lower. Maintain muscle and physical activity. Make sure calcium, vitamin D and protein intake support bone health.

This isn't about adding another ten things to your menopause plan.

It is about shifting from symptom survival to long term health protection once you have the capacity to do so.

Step 9: Reassess what is still bothering you

Now look again at the symptoms you identified at the beginning.

What improved?

What didn't?

Perhaps improving night sweats allowed you to sleep and suddenly your brain fog, cravings and irritability improved considerably.

Perhaps reducing alcohol transformed your sleep but did nothing for your hot flushes.

Perhaps you are eating well, sleeping better and exercising, but still having ten severe hot flushes a day.

Perhaps vaginal dryness and painful sex haven't changed at all.

This is useful information because it tells us where lifestyle has reached its limit.

And that matters.

There is no virtue in spending another year trying increasingly complicated lifestyle interventions for a symptom that has an effective medical treatment.

Step 10: Know when treatment is the sensible next step

Lifestyle can improve health and may reduce some menopause symptoms, but it cannot prevent ovarian ageing and it cannot guarantee a symptom free menopause.

For moderate to severe hot flushes and night sweats, menopausal hormone therapy is the most effective treatment for appropriate women. Evidence based non hormonal options also exist.

For genitourinary syndrome of menopause, local vaginal treatments including vaginal estrogen can be extremely effective.

Heavy or abnormal bleeding may require investigation and specific treatment.

Significant mood symptoms may need psychological or medical treatment in addition to menopause care.

The decision isn't "natural versus medical."

It is what is the most appropriate intervention for this woman, for this symptom, at this point in her life?

That is where genuinely individualised menopause care begins.

And it is exactly what we're going to explore in the next article.

Your first plan

If you feel overwhelmed, don't leave this article with ten new jobs.

Start with three questions.

What is affecting my quality of life the most?

What might be making that problem worse?

Does this need lifestyle support, investigation, specific treatment or a combination of them?

Address the dominant symptoms first. Prioritise sleep and mental wellbeing when they are compromised. Make sure you are adequately nourished. Remove obvious symptom amplifiers. Create genuine recovery. Then progressively build strength, fitness and long term metabolic and bone protection.

You don't need to do everything at once.

You need to do the right thing next.

Which biomarkers I recommend checking

Testing should follow the clinical picture rather than menopause automatically triggering an enormous hormone panel.

If heavy bleeding, fatigue, hair shedding, weakness or poor exercise tolerance are present, a full blood count and ferritin can help identify anaemia or iron deficiency.

When symptoms could indicate thyroid dysfunction, TSH and free T4 are appropriate starting points.

For broader midlife health, I recommend knowing your blood pressure, fasting glucose, HbA1c and lipid profile, with additional cardiometabolic testing based on personal and family history.

Bone health assessment should be based on age and individual risk factors. Vitamin D testing may be appropriate in women at risk of deficiency, while bone density testing may be indicated when osteoporosis risk is increased.

Routine estradiol, progesterone and FSH testing usually isn't necessary to diagnose typical perimenopause in otherwise healthy women over 45 because hormone concentrations can fluctuate substantially.

We will look at hormone testing properly in Article 4, including when FSH and estradiol are useful, what testosterone testing can tell us, what thyroid testing has to do with menopause symptoms and why some popular commercial hormone panels may create more confusion than clarity.

Your next step

Once the symptoms that are destabilising you are being addressed and the foundations are becoming stronger, we can move from stabilisation to more targeted treatment.

In the next article, we'll look at menopausal hormone therapy, estrogen and progesterone, systemic versus vaginal estrogen, non hormonal options, testosterone, symptom specific treatment and where supplements genuinely fit.
