Menopause

Menopause is a natural biological process that marks the end of a woman’s menstrual cycles and reproductive years.

It is officially diagnosed after 12 consecutive months without a menstrual period.

Menopause typically occurs between the ages of 45 and 55, but it can also happen earlier or later. 

The transitional phase leading up to menopause, known as perimenopause, can last several years. During this time, women may experience a range of physical and emotional symptoms due to fluctuating hormone levels.

Conditions Associated with Menopause

Natural menopause is the most common type of menopause, occurring as a result of the natural decline in reproductive hormones.

  • Causes: The ovaries gradually produce less oestrogen and progesterone, leading to the end of menstruation.
  • Symptoms: Hot flashes, night sweats, irregular periods, vaginal dryness, mood changes, weight gain, and sleep disturbances.
  • Risk Factors: Age, family history, smoking, and certain medical treatments (e.g., chemotherapy).
  • Treatment Options: Lifestyle changes, hormone replacement therapy (HRT), non-hormonal medications, and complementary therapies.

Premature menopause occurs before the age of 40.

  • Causes: Genetic factors, autoimmune diseases, surgical removal of the ovaries, or medical treatments like chemotherapy and radiation.
  • Symptoms: Similar to natural menopause but can also include infertility and emotional distress due to the early onset.
  • Risk Factors: Family history, certain medical conditions, and treatments.
  • Treatment Options: HRT, fertility treatments, and psychological support.

Perimenopause is the transitional period leading up to menopause, characterised by hormonal fluctuations.

  • Causes: Declining ovarian function and hormone production.
  • Symptoms: Irregular periods, hot flashes, night sweats, sleep problems, mood swings, and vaginal dryness.
  • Risk Factors: Age (typically starts in the 40s), smoking, and family history.
  • Treatment Options: Lifestyle modifications, HRT, and symptom-specific treatments.

Induced menopause results from medical interventions, such as surgery or chemotherapy.

  • Causes: Surgical removal of the ovaries (oophorectomy), chemotherapy, or radiation therapy.
  • Symptoms: Immediate onset of menopausal symptoms like hot flashes, night sweats, and vaginal dryness.
  • Risk Factors: Underlying medical conditions requiring such treatments.
  • Treatment Options: HRT, non-hormonal medications, and support for managing symptoms.

Menopause is primarily caused by the natural ageing process and the decline in ovarian function. Other causes include:

  • Genetic Factors: Family history can influence the age of onset.
  • Medical Treatments: Chemotherapy, radiation therapy, and surgical removal of the ovaries can trigger menopause.
  • Autoimmune Diseases: Conditions like thyroid disease and rheumatoid arthritis can affect ovarian function.
  • Lifestyle Factors: Smoking and high body mass index (BMI) can influence the timing of menopause.

Menopausal symptoms can vary widely among women but commonly include:

  • Hot Flashes and Night Sweats: Sudden feelings of heat, often accompanied by sweating and flushed skin.
  • Irregular Periods: Changes in menstrual cycle length and flow.
  • Vaginal Dryness and Discomfort: Reduced lubrication and elasticity, leading to discomfort during intercourse.
  • Mood Changes: Increased risk of mood swings, anxiety, and depression.
  • Sleep Disturbances: Difficulty falling asleep or staying asleep, often due to night sweats.
  • Weight Gain: Changes in metabolism and fat distribution, particularly around the abdomen.
  • Cognitive Changes: Memory lapses and difficulty concentrating, sometimes referred to as “brain fog”.

Risk Factors for Menopause

Several factors can influence the timing and experience of menopause:

  • Age: Most women experience menopause between 45 and 55 years of age.
  • Family History: Genetics play a role in determining the age of onset.
  • Lifestyle Factors: Smoking, obesity, and lack of physical activity can impact the timing and severity of menopausal symptoms.
  • Medical History: Treatments like chemotherapy and radiation, as well as surgical removal of the ovaries, can induce menopause.

Treatment Options for Menopause

Treatment for menopause focuses on managing symptoms and improving quality of life. Options include:

Lifestyle Changes

  • Diet: Eating a balanced diet rich in fruits, vegetables, whole grains, and lean proteins can help manage weight and improve overall health.
  • Exercise: Regular physical activity can reduce hot flashes, improve mood, and promote better sleep.
  • Stress Management: Techniques such as yoga, meditation, and deep breathing exercises can help manage stress and anxiety.

MHT involves taking oestrogen and progesterone to relieve menopausal symptoms. It can be administered in various forms, including pills, patches, gels, and creams.

  • Benefits: Effective in reducing hot flashes, night sweats, vaginal dryness, and preventing bone loss.
  • Risks: Potential increased risk of breast cancer, blood clots, stroke, and heart disease. It is important to discuss the risks and benefits with a healthcare provider.

Non-hormonal treatments can be effective for women who cannot or choose not to take HRT.

  • Antidepressants: Certain antidepressants (e.g., SSRIs and SNRIs) can help reduce hot flashes and mood swings.
  • Gabapentin: Originally used for seizures, it can also help reduce hot flashes.
  • Clonidine: A blood pressure medication that can reduce hot flashes and night sweats.

Vaginal oestrogen comes in the form of creams, tablets, or rings and is used to treat vaginal dryness and discomfort.

  • Benefits: Provides localised relief with minimal absorption into the bloodstream.
  • Risks: Minimal compared to systemic  MHT and is not regarded as MHT, but should still be discussed with a healthcare provider.

Some women find relief from menopausal symptoms through complementary therapies.

  • Herbal Supplements: Black cohosh, red clover, and soy products may help reduce hot flashes, but efficacy and safety are variable.
  • Acupuncture: May help alleviate hot flashes and improve sleep.
  • Mind-Body Practices: Yoga, tai chi, and mindfulness meditation can improve overall well-being and reduce stress.

National Approach to Menopause in Australia

In Australia, there is increasing recognition of the importance of providing comprehensive care and support for individuals experiencing menopause. The National Women’s Health Strategy 2020–2030 highlights menopause as a key priority, emphasising the need for equitable access to evidence-based treatments, awareness initiatives, and multidisciplinary care to improve quality of life.

Healthcare providers, including gynaecologists, general practitioners, and allied health professionals, play a crucial role in managing menopausal symptoms and addressing associated health risks, such as osteoporosis and cardiovascular disease. The Australasian Menopause Society (AMS) offers guidelines and resources to ensure healthcare professionals deliver high-quality, evidence-based care.

Public health efforts focus on increasing awareness of menopause, reducing stigma, and encouraging individuals to seek medical advice for symptom management. These initiatives also emphasise the importance of healthy lifestyle choices, preventive care, and education to support overall wellbeing during the menopausal transition and beyond.
