Understanding Perimenopause: Early Symptoms, Hormonal Changes and Treatment Options

Perimenopause is the stage leading up to menopause, when hormonal changes may affect your menstrual cycle, sleep, mood and overall wellbeing. Recognising the early symptoms can help you access appropriate support and treatment.
At Metropol Doctors in Carindale, our GPs provide personalised women’s health care to help you understand perimenopause and manage its symptoms.
What Is Perimenopause?
Perimenopause is the transition before menopause. During this stage, the ovaries gradually produce less oestrogen and progesterone, the hormones that regulate the menstrual cycle.
Hormone levels can rise and fall unpredictably. As a result, periods may become irregular, and symptoms can vary from month to month.
Perimenopause is different for everyone. Some people have mild symptoms, while others experience changes that affect work, relationships, sleep and daily activities.
When Does Perimenopause Begin?
Perimenopause commonly begins during the 40s, although it can start earlier or later. The transition may continue for several years before menopause, which is reached after 12 consecutive months without a menstrual period.
The timing and symptoms can be influenced by factors such as family history, medical conditions, surgery and some treatments.
Early Symptoms of Perimenopause
Changes in your menstrual cycle are often one of the first signs. Your periods may:
- Come more or less often.
- Become lighter or heavier.
- Last longer or fewer days.
- Occur after a longer gap.
- Stop for some months before returning.
Other possible symptoms include:
- Hot flushes and night sweats.
- Difficulty sleeping.
- Daytime tiredness.
- Mood changes, anxiety or low mood.
- Headaches or migraines.
- Breast tenderness.
- Vaginal dryness.
- Reduced sexual desire.
- Muscle aches and joint pain.
- Difficulty concentrating or forgetfulness.
- Changes in weight.
Not every symptom is caused by perimenopause. Thyroid problems, anaemia, pregnancy, medication side effects and other health conditions can cause similar changes. A GP assessment can help identify the likely cause.
How Hormonal Changes Affect the Body
Oestrogen and progesterone influence more than the menstrual cycle. Changes in these hormones may affect:
- Body temperature regulation, contributing to hot flushes.
- Sleep patterns and energy levels.
- Mood and emotional wellbeing.
- Vaginal and urinary health.
- Bone health.
- Sexual desire and comfort.
- Menstrual bleeding patterns.
Because hormone levels fluctuate during perimenopause, symptoms may not follow a predictable pattern. You may feel well for several weeks and then experience several symptoms at once.
When Should You See a GP?
Book an appointment if symptoms are affecting your quality of life, sleep, work or relationships.
You should also see your GP if:
- Your periods become very heavy.
- Bleeding lasts longer than usual.
- You bleed between periods.
- You bleed after sex.
- Period pain becomes severe or changes significantly.
- You experience persistent low mood or anxiety.
- Symptoms begin before the expected age range.
- You are concerned that symptoms may be caused by another condition. Heavy or unusual bleeding should not automatically be assumed to be perimenopause. Your doctor may recommend an examination or tests to investigate the cause.
Seek urgent medical advice if you experience extremely heavy bleeding, fainting, severe pelvic pain or thoughts of harming yourself.
How Is Perimenopause Diagnosed?
Your GP will discuss your symptoms, menstrual history, medical history and treatment preferences. You may find it helpful to track:
- Period dates and bleeding changes.
- Hot flushes and night sweats.
- Sleep quality.
- Mood changes.
- Headaches or migraines.
- Pain or vaginal symptoms.
- Medicines and supplements.
In many people over 45, perimenopause can be assessed based on symptoms and menstrual changes. Blood tests may be considered when symptoms are unusual, begin earlier than expected or another condition needs to be investigated.
Your GP may also assess blood pressure, general health and other factors that may affect treatment choices.
Treatment Options for Perimenopause
Treatment depends on your symptoms, medical history, preferences and individual risk factors.
Menopausal Hormone Therapy
Menopausal hormone therapy (MHT), also called hormone replacement therapy, may help reduce symptoms such as hot flushes, night sweats and vaginal dryness. It may be available in forms such as tablets, gels, patches or creams.
The appropriate treatment depends on factors including whether you have a uterus, your symptoms and your personal and family medical history. Your GP can explain the potential benefits, risks and alternatives.
Non-Hormonal Medicines
Non-hormonal prescription medicines may be suitable for some people, particularly when MHT is not appropriate or preferred. Depending on the symptoms, treatment may help with hot flushes, night sweats, sleep problems or mood changes.
Important: Do not start over-the-counter or complementary products without discussing them with your doctor, as they may interact with other medicines.
Vaginal Symptom Relief
Vaginal dryness or discomfort may improve with:
- Water-based or silicone-based lubricants.
- Vaginal moisturisers.
- Prescription local treatments where appropriate.
- Medical assessment if symptoms continue.
Speak with your GP if you experience pain during sex, recurrent urinary symptoms or ongoing discomfort.
Lifestyle Strategies
Lifestyle changes may help reduce symptoms and support your general health. Consider:
- Regular physical activity, including strength and weight-bearing exercise.
- A balanced diet with adequate calcium and protein.
- A consistent sleep routine.
- Limiting alcohol and caffeine if they trigger symptoms.
- Avoiding smoking and vaping.
- Managing stress through relaxation, counselling or mindfulness.
- Wearing light layers during hot flushes.
- Keeping the bedroom cool at night.
Lifestyle strategies may support treatment but should not replace medical care when symptoms are significant.
