Perimenopause Symptoms Signs Age Treatment Options & When to See a GP

Perimenopause can make you feel unlike yourself. You might notice that your periods have become unpredictable, your sleep is getting worse, or your mood changes without an obvious reason. You may also experience brain fog, joint aches or sudden feelings of heat that interrupt your day.

These changes can be confusing, particularly when they develop gradually or overlap with the pressures of work, family and everyday life.

Perimenopause is the transitional stage before menopause, when hormone levels fluctuate and menstrual cycles begin to change. It is a natural part of ageing, but that does not mean you have to put up with symptoms that affect your quality of life.

Understanding the common and less familiar perimenopause symptoms, when this transition usually begins and which treatments may help can make it easier to decide when to seek medical advice.

If you live in Aspley or the surrounding Brisbane area, your GP can help assess your symptoms, discuss suitable management options and identify other possible causes of the changes you are experiencing.

What Is Perimenopause?

Perimenopause is the transition leading up to menopause. During this time, the ovaries gradually change their hormone production, particularly the production of oestrogen. Hormone levels can fluctuate considerably, which is why symptoms may vary from one month to the next.

Menstrual cycles may become shorter, longer, lighter or heavier. You may experience hot flushes, sleep disturbances, changes in mood or difficulty concentrating. Some people have several symptoms, while others notice very few.

Menopause is different from perimenopause. Menopause is reached when you have gone 12 consecutive months without a menstrual period, provided there is no other cause for the absence of periods.

Perimenopause can last for several years. Symptoms may continue into post menopause, although their pattern and intensity can change over time.

It is important to remember that not every new symptom in your 40s or 50s is necessarily related to perimenopause. Conditions such as thyroid disorders, iron deficiency, anxiety and sleep problems can cause similar symptoms and may require different treatment.

What Age Does Perimenopause Start?

Perimenopause commonly begins during the 40s, although the timing varies between individuals. Some people notice changes in their late 30s, while others do not experience noticeable symptoms until later.

Menopause in Australia generally occurs between the ages of 45 and 55, with the average age around 51. Perimenopause begins before the final menstrual period, so there is no single age at which everyone should expect it to start.

Several factors may influence the timing and experience of this transition, including family history, smoking, certain medical treatments and surgery affecting the ovaries.

Signs That Perimenopause May Be Starting

You may be entering perimenopause if you notice a combination of changes, such as:

Periods that become irregular or change in flow.
Hot flushes or night sweats.
Difficulty falling asleep or staying asleep.
Increased irritability, anxiety or mood changes.
Vaginal dryness or discomfort during sex.
Reduced concentration or memory difficulties.

Symptoms alone cannot confirm perimenopause. Your GP can consider your age, menstrual history, symptoms, medications and overall health to help determine what may be happening.

If menopause symptoms begin before age 45, particularly before age 40, medical assessment is important because early menopause or premature ovarian insufficiency may need further investigation and management.

Common Perimenopause Symptoms You Should Know

Perimenopause affects people differently. Symptoms may develop gradually, fluctuate in intensity or appear at different stages of the transition.

1. Irregular Periods

Changes to your menstrual cycle are often among the earliest signs of perimenopause.

Your periods may arrive earlier or later than expected, become lighter or heavier, or vary in duration. You may also skip periods for a month or longer.

These changes occur as ovulation becomes less predictable.

However, heavy bleeding, bleeding between periods, bleeding after sex or any bleeding after menopause should not automatically be attributed to hormonal changes. Arrange a GP assessment to determine the cause.

2. Hot Flushes and Night Sweats

Hot flushes are sudden sensations of warmth, often affecting the face, neck and chest. You may also experience sweating, flushing, a racing heartbeat or chills afterwards.

Night sweats are similar episodes that happen during sleep. They can leave you feeling uncomfortable, disturb your rest and contribute to daytime fatigue.

Triggers vary, but some people notice that hot environments, stress, alcohol or spicy foods make symptoms worse.

3. Sleep Problems and Fatigue

You may find it harder to fall asleep, wake frequently during the night or wake earlier than usual.

Night sweats can contribute to disrupted sleep, but sleep difficulties may also occur without them. Poor sleep can then affect your energy, concentration, mood and ability to manage daily activities.

If fatigue persists despite adequate rest, your GP may consider other causes, including iron deficiency, thyroid problems, sleep apnoea or medication effects.

4. Mood Changes, Anxiety and Irritability

Hormonal fluctuations, interrupted sleep and the demands of everyday life can all influence emotional wellbeing during perimenopause.

Some people notice increased irritability, low mood, anxiety or reduced emotional resilience. Others find that symptoms of an existing mental health condition become more difficult to manage.

These experiences should not be dismissed as simply part of getting older. Your GP can discuss symptom management and assess whether additional mental health support would be helpful.

5. Brain Fog and Difficulty Concentrating

You might struggle to find the right word, forget why you entered a room or find it harder to concentrate on tasks that once felt straightforward.

Some people describe this as brain fog. Sleep disruption, stress and hormonal changes may all contribute.

Although occasional concentration difficulties can occur during perimenopause, persistent or worsening memory problems should be assessed rather than automatically attributed to menopause.

6. Vaginal Dryness and Changes in Sexual Comfort

Changing oestrogen levels can affect vaginal and urinary tissues. You may experience dryness, irritation, discomfort during sex or reduced sexual comfort.

These symptoms can develop during perimenopause and may persist after menopause without treatment.

Vaginal moisturisers and lubricants may help some people. Prescription vaginal oestrogen can also be an option for suitable patients after a discussion with their GP.

Pain, unusual discharge, sores or unexplained bleeding should be assessed to exclude other causes.

Lesser-Known Perimenopause Symptoms

Not every perimenopause symptom involves periods or hot flushes. Some changes can be unexpected and may be difficult to connect with hormonal fluctuations.

Possible symptoms include:

Joint and muscle aches: You may notice stiffness, discomfort or more frequent aches.
Headaches or migraine changes: Existing headaches may become more frequent or change in pattern.
Palpitations: You may notice your heart beating rapidly, strongly or irregularly.
Changes in body composition: Weight distribution may change, including increased abdominal fat, although ageing, activity and other factors also play a role.
Skin and hair changes: Skin may feel drier, and some people notice changes in hair thickness or texture.
Urinary symptoms: Increased urgency, discomfort or recurrent urinary tract infections may occur, particularly as urogenital tissues change.
Changes in libido: Sexual desire may increase, decrease or fluctuate.
Reduced exercise recovery: Sleep disruption, joint discomfort and changes in routine may make physical activity feel more difficult.

These symptoms are not exclusive to perimenopause, and some are not necessarily caused by hormonal changes. For example, palpitations may have cardiac, thyroid-related or other causes.

If a symptom is new, persistent, severe or affecting your everyday life, speak with your GP rather than assuming it is hormonal.

Perimenopause or Another Health Condition?

Because perimenopause can affect several areas of your health, its symptoms sometimes overlap with other conditions.

Symptom	Possible perimenopause link	Other causes a GP may consider
Fatigue	Disrupted sleep or night sweats	Iron deficiency, thyroid disorders, sleep problems
Mood changes	Hormonal fluctuations and poor sleep	Anxiety, depression, other stressors
Irregular periods	Changes in ovulation	Pregnancy, thyroid conditions, fibroids or other gynaecological conditions
Brain fog	Sleep disturbance and hormonal changes	Medication effects, stress, other medical conditions
Palpitations	May occur during the transition	Heart rhythm problems, thyroid disorders, anaemia
Joint aches	May occur during perimenopause	Arthritis, injury or other inflammatory conditions

This is why an individual assessment matters. Your GP can help determine whether symptoms fit the expected pattern of perimenopause or whether further investigation is appropriate.

What Tests May Your GP Suggest?

There is no single test that reliably confirms perimenopause in everyone.

For otherwise healthy people aged 45 or older who have typical symptoms and menstrual changes, perimenopause and menopause are generally assessed clinically. Routine hormone blood tests are usually not necessary because hormone levels can fluctuate considerably during this transition.

Depending on your age, symptoms and medical history, your GP may recommend:

A review of your menstrual history: Your GP may ask about changes in your periods, the timing of your symptoms and whether you have gone for extended periods without menstruation.

A medication and health review: Some medicines and medical conditions can cause symptoms similar to perimenopause. Your GP may review your current treatments, family history and other health concerns.

Blood tests where appropriate: Tests may be considered if your symptoms suggest another condition. For example, a full blood count and iron studies may be appropriate when heavy periods or fatigue raise concerns about anaemia or iron deficiency. Thyroid testing may be considered when symptoms suggest a thyroid disorder.

Pregnancy testing where relevant: Pregnancy remains possible during perimenopause. If your periods are irregular and pregnancy is possible, your GP may recommend a pregnancy test.

Hormone testing in selected circumstances: Testing may be appropriate for younger people with suspected early menopause or premature ovarian insufficiency, or when the diagnosis is uncertain. Your GP can explain which tests, if any, are suitable.

Additional investigations may be needed for unusual bleeding, pelvic pain, breast symptoms or other concerns. The purpose is to identify the cause of your symptoms and guide appropriate care, not simply to confirm a hormonal transition.

Perimenopause Treatment Options: What Can Help?

You do not need to wait until your periods stop completely before seeking help for troublesome symptoms.

Treatment depends on which symptoms you experience, how much they affect your daily life, your medical history and your personal preferences. Options may include menopausal hormone therapy, non-hormonal medicines, local vaginal treatments and practical lifestyle support.

1. Menopausal Hormone Therapy (MHT)

Menopausal hormone therapy can be an effective option for managing troublesome hot flushes and night sweats. It may also help with certain other menopause-related symptoms, depending on the treatment used.

MHT generally involves oestrogen. People who have a uterus usually also need a progestogen to protect the lining of the uterus from the effects of oestrogen.

Treatment may be available in different forms, including patches, gels, sprays or tablets, depending on the product and individual circumstances.

MHT is not suitable for everyone. Your GP will consider factors such as your age, symptoms, medical history, risk factors and whether you have had a hysterectomy. The potential benefits and risks should be discussed before treatment begins and reviewed over time.

The aim is to find an appropriate treatment that improves your quality of life while taking your individual health needs into account.

2. Non-Hormonal Treatment Options

If MHT is unsuitable or you prefer not to use it, other options may be available.

Certain prescription medicines can help reduce hot flushes or address specific symptoms. Psychological therapies, including cognitive behavioural therapy (CBT), may help with menopause-related sleep difficulties and the distress associated with symptoms.

The most appropriate approach depends on the symptoms being treated. Your GP can discuss the evidence, potential side effects and suitability of different options.

3. Vaginal Oestrogen and Treatments for Genitourinary Symptoms

Vaginal dryness, discomfort during sex and some urinary symptoms may respond to vaginal moisturisers, lubricants or prescription vaginal oestrogen.

Vaginal oestrogen is a local treatment designed to improve symptoms affecting vaginal and urinary tissues. It differs from systemic MHT, which is used to treat symptoms such as hot flushes and night sweats.

Your GP can help you choose a suitable option and advise whether further assessment is needed, particularly if you have unexplained bleeding or a history of certain hormone-sensitive conditions.

4. Review Your Treatment Regularly

Your symptoms and preferences may change throughout perimenopause.

Regular reviews allow you and your GP to assess whether a treatment is working, discuss side effects and reconsider options when your circumstances change.

Do not start, stop or change prescribed hormone treatment without discussing it with your healthcare professional.

Lifestyle Support During Perimenopause: Diet, Exercise and Physiotherapy

Lifestyle changes cannot prevent every symptom, but they may support your general health, sleep, mood, bone strength and physical function during the menopause transition.

Eat a Balanced, Nutrient-Rich Diet

Aim for a varied diet that includes vegetables, fruit, wholegrains, protein-rich foods, legumes, nuts and appropriate sources of healthy fats.

Calcium-rich foods and adequate vitamin D are important for bone health. Your individual needs may depend on your diet, sun exposure, medical history and other risk factors.

If weight changes, digestive symptoms or dietary restrictions are concerns, an accredited practising dietitian can help you develop a realistic eating plan suited to your needs.

Avoid restrictive diets or unproven supplements marketed as hormone-balancing solutions without seeking reliable medical advice.

Keep Moving Regularly

Regular physical activity can support cardiovascular health, bone strength, muscle function, mood and sleep.

A balanced routine may include:

Weight-bearing activity, such as walking or dancing.
Resistance training to maintain muscle strength.
Balance exercises to support mobility.
Activities you enjoy and can maintain consistently.

Start at a level that suits your current fitness and health. If joint pain, pelvic floor symptoms or other physical concerns make exercise uncomfortable, a physiotherapist can help adapt your activities.

Consider Pelvic Health Physiotherapy

Some people experience urinary leakage, pelvic pressure or discomfort during perimenopause. These symptoms may be related to pelvic floor dysfunction or changes in the tissues around the vagina and urinary tract.

A pelvic health physiotherapist can assess pelvic floor function and provide an individualised plan, which may include appropriate exercises, relaxation techniques and strategies for bladder symptoms.

Not everyone needs pelvic floor strengthening exercises. The right approach depends on whether your pelvic floor muscles are weak, overactive or affected by another condition.

Discuss persistent urinary symptoms, pain or recurrent infections with your GP as well, because physiotherapy may be one part of a broader management plan.

Protect Your Sleep and Emotional Wellbeing

Try to maintain a regular sleep schedule and a comfortable sleeping environment. If night sweats are a problem, lighter bedding, breathable sleepwear and a cooler bedroom may help.

Relaxation practices, enjoyable social activities and appropriate psychological support can also contribute to wellbeing.

If sleep problems, anxiety or low mood persist, seek professional advice. You do not have to manage these symptoms alone.

When Should You See a GP About Perimenopause Symptoms?

Consider booking an appointment if:

Your periods have changed significantly or become difficult to manage.
Hot flushes or night sweats interfere with sleep or daily activities.
You experience persistent anxiety, low mood or difficulty concentrating.
Vaginal dryness, painful sex or urinary symptoms affect your comfort.
You have ongoing fatigue, palpitations or unexplained physical changes.
Symptoms begin before age 45, particularly before age 40.
You want to understand your treatment options or review your long-term health.

Seek urgent medical assessment for very heavy bleeding, particularly if you feel faint or weak. Call Triple Zero (000) for severe chest pain, severe difficulty breathing or other medical emergencies. Any bleeding after menopause needs prompt assessment, even if it is light or happens only once.

If you are unsure whether your symptoms are related to perimenopause, your GP can help you work through the possibilities and decide on appropriate next steps.

Frequently Asked Questions About Perimenopause

What are the first signs of perimenopause?

Changes in menstrual cycles are often an early sign. Other possible symptoms include hot flushes, night sweats, sleep difficulties, mood changes and difficulty concentrating. Symptoms vary, so a GP assessment may help clarify the cause.

What age does perimenopause usually start?

Perimenopause commonly begins during the 40s, although some people notice changes in their late 30s and others start later. Menopause itself occurs at an average age of around 51 in Australia.

How long does perimenopause last?

Perimenopause can last several years, and its duration varies between individuals. Symptoms may change over time and can continue after the final menstrual period.

Can perimenopause cause anxiety and brain fog?

Yes, some people experience anxiety, mood changes and difficulty concentrating during perimenopause. Sleep disruption and other factors may contribute. Persistent or severe symptoms should be discussed with a GP to assess possible causes and treatment options.

Do I need a blood test to confirm perimenopause?

Not usually if you are 45 or older and have typical symptoms and menstrual changes. Hormone levels fluctuate during perimenopause, making routine hormone tests less useful. Your GP may recommend blood tests when another condition is suspected or when early menopause is being investigated.

What is the best treatment for perimenopause symptoms?

There is no single best treatment for everyone. Menopausal hormone therapy may help with troublesome hot flushes and night sweats, while vaginal treatments, non-hormonal medicines, psychological therapies and lifestyle support may help with particular symptoms. Your GP can help identify suitable options.

Can I get pregnant during perimenopause?

Yes. Ovulation may become irregular, but pregnancy remains possible during perimenopause. If you do not want to become pregnant, discuss suitable contraception with your healthcare professional. Ask your GP when contraception can safely be stopped.

When should I worry about irregular periods during perimenopause?

Some changes in menstrual timing and flow are common, but very heavy bleeding, bleeding between periods, bleeding after sex or bleeding after menopause needs medical assessment. Seek urgent care if heavy bleeding is accompanied by faintness, severe weakness or other concerning symptoms.

Can diet and exercise improve perimenopause symptoms?

A balanced diet, regular physical activity, adequate sleep and appropriate stress management can support general health and wellbeing. These measures may help with some aspects of the transition but may not fully relieve symptoms. Additional treatment may be worthwhile if symptoms affect your quality of life.
