Perimenopause can feel confusing because it does not always arrive in an obvious way. For some women, the first sign is a change in their menstrual cycle. For others, it is disrupted sleep, hot flushes, mood shifts, heavier bleeding, brain fog, joint aches or simply a sense that their body is behaving differently from how it used to.
At Shire Family Medical in Sutherland, perimenopause concerns are a regular and important part of women’s health care. Shire Family Medical, a GP medical centre at 154 Flora Street, Sutherland, supports women through this stage with care that looks at the full clinical picture — not just individual symptoms in isolation.
This article explains common perimenopause symptoms, when they are worth discussing with your GP, and what a GP review can help clarify — even if you are not yet sure whether you are in perimenopause.
What Is Perimenopause?
Perimenopause is the transitional stage leading up to menopause. Menopause itself is defined as the point when 12 consecutive months have passed without a menstrual period — everything leading up to that point is perimenopause.
Most women begin perimenopause somewhere between their early 40s and early 50s, though timing varies. The average age of natural menopause in Australia is around 51 to 52, and perimenopause may begin several years before that. For some women, the transition takes as few as two years. For others, it can last close to a decade — which explains why symptoms can feel unpredictable and inconsistent over a long stretch of time.
Some months may feel quite settled. Others bring noticeable changes. Perimenopause is gradual by nature, and symptoms often come and go rather than appearing all at once.
It is also worth knowing that ovulation may still occur during perimenopause, even when periods become irregular. This means pregnancy is still possible, and contraception may still be relevant — something worth discussing with your GP.
How Many Perimenopause Symptoms Are There?
Perimenopause can involve more than 30 recognised symptoms — far more than the hot flushes most people associate with this stage. Some women experience only a handful of changes. Others notice effects across sleep, mood, physical health, cognition and sexual wellbeing, sometimes all at once and sometimes across different phases of the transition.
Common perimenopause symptoms include:
- Irregular or changing periods
- Hot flushes and night sweats
- Disrupted sleep and insomnia
- Fatigue and low energy
- Brain fog and difficulty concentrating
- Mood changes, anxiety and irritability
- Joint and muscle pain
- Weight changes, particularly around the abdomen
- Vaginal dryness and discomfort
- Reduced libido
- Breast tenderness
- Headaches and migraines
- Itchy or dry skin
- Urinary symptoms
The breadth of possible symptoms is one reason perimenopause can be difficult to recognise at first — and one reason a GP review is useful even when you are uncertain whether your symptoms are hormonal.
Period Changes — Often the First Clue
Changes to the menstrual cycle are among the most common early signs of perimenopause, and often the first thing women notice.
Periods may arrive earlier or later than usual, become heavier or lighter, last for more or fewer days, or become harder to predict overall. Spotting between periods, or noticing more pronounced premenstrual symptoms, is also common during this transition.
Not every cycle change is hormonal in origin, however. Heavy bleeding, bleeding between periods, bleeding after sex, any bleeding after menopause, or bleeding that causes dizziness or significant fatigue should be discussed with a GP rather than assumed to be perimenopause. Our article on heavy periods and when to speak with your GP explains which bleeding changes are worth investigating and how low iron can become part of the picture.
Hot Flushes and Night Sweats
Hot flushes — a sudden wave of warmth through the face, neck or body, sometimes followed by sweating or chills — are among the most recognised symptoms of perimenopause. Night sweats are a similar experience during sleep and can significantly disrupt rest and recovery.
For some women, hot flushes are occasional and manageable. For others, they are frequent enough to affect concentration, work, exercise, relationships and sleep quality over months or years.
It is worth speaking with your GP if hot flushes or night sweats are affecting daily life — especially if they are frequent, severe, associated with other symptoms such as unexplained weight loss or fever, or do not feel consistent with your usual health. Your GP can help assess whether perimenopause is the likely cause, whether other causes need to be considered, and which management options may suit your health history and preferences.
Sleep Problems, Fatigue and Brain Fog
Sleep disturbance is one of the more disruptive perimenopause symptoms and often compounds other changes. Some women find it difficult to fall asleep. Others wake repeatedly or rise early and cannot return to sleep. Night sweats frequently make this worse.
The knock-on effects of poor sleep — fatigue, reduced concentration, mood changes, difficulty finding words, slower thinking — are what many women describe as brain fog. These experiences are real and clinically recognised, but they can also overlap with other causes: thyroid conditions, low iron, anaemia, vitamin deficiencies, anxiety, depression, and medication effects, among others.
If persistent fatigue seems out of proportion to your circumstances, your GP may discuss whether blood tests are appropriate. Our article on how blood test results work explains how results are interpreted in the context of your full health picture, rather than as isolated numbers.
Mood, Anxiety and Emotional Changes
Perimenopause can affect emotional wellbeing in ways that some women find difficult to name or explain. Irritability, low mood, anxiety, tearfulness, reduced emotional resilience, or a sense of not quite feeling like yourself are all recognised features of this transition.
These symptoms deserve to be taken seriously. They should not be dismissed, but they also should not be left unaddressed simply because they may have a hormonal origin. A GP can explore the full picture: sleep quality, stress, life circumstances, mental health history, medications, alcohol, and how physical and emotional symptoms may be interacting.
Seek help promptly if mood symptoms are severe, persistent, affecting relationships or work, or if you have any concerns about your safety or wellbeing. Mental health support can be an important part of perimenopause care.
Physical Symptoms — Joint Pain, Muscle Aches and Weight Changes
Oestrogen plays a role in several processes beyond the reproductive system, which means perimenopause can produce physical symptoms that feel unrelated to hormonal change at first.
Joint pain and muscle aches are more common during perimenopause than many women expect. Knees, hips, wrists and hands may feel stiffer or more uncomfortable, particularly in the morning or after sitting for extended periods. These symptoms are sometimes initially mistaken for early arthritis, particularly in women in their mid-40s who are not anticipating a hormonal cause.
Weight changes — particularly changes in how weight distributes, often increasing around the abdomen — can also occur during perimenopause, even without significant changes to diet or exercise. Breast tenderness, headaches or migraines, itchy or dry skin, and changes to hair texture are among the other physical symptoms that women may notice during this transition.
If new or worsening physical symptoms feel unexplained, a GP review can help establish whether perimenopause may be contributing and whether any further assessment is appropriate.
Sexual Health and Vaginal Symptoms
Vaginal dryness, discomfort during sex, changes in sexual desire, urinary urgency or frequency, and recurrent irritation are common during perimenopause and can affect quality of life significantly. These symptoms can feel difficult to raise in a consultation, but they are experienced by many women during this stage and there are management approaches that may help.
Your GP may ask about dryness, pain, bleeding after sex, urinary symptoms, sexual wellbeing and whether cervical screening or other assessment is due. The most appropriate approach depends on your symptoms, preferences and medical history.
You do not need to wait until symptoms become severe before discussing them. These are a recognised part of women’s health care at this life stage.
Contraception Still Matters During Perimenopause
Irregular periods during perimenopause do not mean fertility has ended. Ovulation can still occur, and pregnancy remains possible. If avoiding pregnancy is important, contraception continues to be relevant during this stage.
The right approach depends on your bleeding pattern, symptoms, medical history and preferences. Some women find a method that also helps manage cycle changes or symptoms. Others need non-hormonal options or need to avoid certain hormone types for medical reasons.
Our article on how to choose a contraception option explains how symptoms, health history and preferences can all shape the conversation with your GP. Shire Family Medical’s women’s health GP services include contraception counselling alongside menopause support, cycle concerns, cervical screening and broader reproductive health care across life stages.
Bone and Heart Health — The Longer View
Perimenopause is not only about managing day-to-day symptoms. It can also be a useful time to think about longer-term health.
Declining oestrogen after menopause can affect bone density, and the years leading up to menopause are often a practical time to establish habits that support bone health — weight-bearing exercise, adequate calcium and vitamin D, and reducing alcohol and tobacco. Your GP can advise on whether bone density assessment is appropriate for your circumstances.
Midlife is also when cardiovascular risk factors — blood pressure, cholesterol, weight, blood glucose — may benefit from closer attention. A GP review during perimenopause can include a broader preventive health check where relevant: blood pressure, cholesterol, diabetes risk, cervical screening, breast health, skin checks, and thyroid or iron levels where clinically indicated.
This does not mean every woman needs every test at every appointment. It means perimenopause can be a natural moment to take stock of preventive health alongside symptom management.
When To Speak With Your GP
Speak with your GP if any symptoms are bothering you, affecting daily life, or if you are uncertain whether changes you are noticing may be related to perimenopause.
It is especially worth seeking a GP review if you have:
- Periods that have become very heavy, irregular or unpredictable
- Bleeding between periods, after sex, or after menopause
- Hot flushes or night sweats that are disturbing sleep or affecting work or daily function
- Persistent fatigue, dizziness or symptoms that may suggest low iron
- Mood changes, anxiety or low mood that are affecting relationships or quality of life
- Vaginal dryness, painful sex or bothersome urinary symptoms
- New joint pain, muscle aches or physical symptoms that feel unexplained
- Questions about contraception, hormone therapy or non-hormonal management options
- Perimenopause symptoms beginning before age 45, or possible early menopause before age 40
If symptoms are sudden, severe or accompanied by other concerning changes, seek medical advice promptly rather than waiting for a routine appointment.
What Your GP May Discuss
A GP will typically begin with your history: what has changed, when symptoms began, how they are affecting you, and whether there are any red flags or other possible causes worth considering.
Depending on your situation, the conversation may cover your menstrual pattern and any bleeding changes, hot flushes and night sweats, sleep, mood, anxiety and mental health, sexual health and urinary symptoms, contraception, blood tests where relevant, management options including hormonal and non-hormonal approaches, and preventive health checks appropriate to your age and risk profile.
You may find it helpful to bring a short list of your main concerns, or a few notes about your periods, sleep, mood and energy. Even brief notes can help make the most of your appointment time.
Perimenopause Care Should Feel Practical, Not Dismissive
Perimenopause is a recognised clinical stage that can involve real and sometimes significant symptoms. The goal of GP-led care is not to medicalise every normal change, but to take symptoms seriously, rule out other causes when needed, and support quality of life throughout the transition.
For women in Sutherland and the Sutherland Shire, Shire Family Medical provides GP-led women’s health care across adolescence, reproductive years, perimenopause and beyond.

Frequently Asked Questions
What is perimenopause?
Perimenopause is the transitional stage leading up to menopause, during which hormone levels fluctuate and the menstrual cycle begins to change. It ends when a woman has gone 12 consecutive months without a period — that point is menopause. Perimenopause can last from a few years to close to a decade, and may involve symptoms such as irregular periods, hot flushes, night sweats, mood changes, sleep disturbance and brain fog.
What are the first signs of perimenopause?
For many women, changes to the menstrual cycle — such as periods arriving earlier or later than usual, or becoming heavier or lighter — are among the first signs of perimenopause. Other early signs can include sleep disturbance, mood changes, hot flushes, and a general sense that the body is behaving differently. Symptoms vary widely from person to person.
How long does perimenopause last?
Perimenopause typically lasts between four and ten years, though the duration varies. The transition begins when menstrual cycles start to change and ends with the final menstrual period. Because it is gradual and symptoms may come and go, many women do not recognise they are in perimenopause until they reflect on how their body has changed over several years.
At what age does perimenopause start?
Most women begin perimenopause in their 40s, though it can start in the late 30s or early 50s. The average age of natural menopause in Australia is around 51 to 52, and perimenopause may begin several years before that. If symptoms of perimenopause begin before age 45, or menopause occurs before age 40, it is particularly important to speak with a GP, as early menopause has specific health implications worth discussing.
Can I still get pregnant during perimenopause?
Yes. Ovulation can still occur during perimenopause, even when periods are irregular. This means pregnancy remains possible. If avoiding pregnancy is important, contraception should be discussed with a GP. Your GP can advise on which options are appropriate given your cycle pattern, symptoms, medical history and preferences.
Do I need blood tests to diagnose perimenopause?
Not always. Perimenopause is often assessed based on symptoms and menstrual changes rather than blood tests alone. Hormone levels can fluctuate significantly during perimenopause, which can make blood tests less reliable as a diagnostic tool during this transition. Blood tests may be useful if your GP wants to check for other causes of symptoms — such as thyroid problems, low iron or anaemia — that can produce overlapping effects.
Can perimenopause cause joint pain and muscle aches?
Yes. Joint pain, muscle aches and stiffness are recognised perimenopause symptoms, linked in part to the role oestrogen plays in joint and tissue health. These symptoms can affect the knees, hips, hands and wrists, and may initially be mistaken for other causes. If new or worsening joint or muscle pain feels unexplained, discussing it with a GP can help clarify whether perimenopause may be contributing.
When should I see a GP about perimenopause symptoms?
See your GP if perimenopause symptoms are affecting your daily life, sleep, mood or work — or if you are simply uncertain whether changes you are noticing may be hormonal. It is particularly important to seek advice if you have heavy or unpredictable bleeding, bleeding after sex or between periods, bleeding after menopause, or symptoms that began before age 45.
