Menopause Stages: From Perimenopause to Postmenopause

The Stages of Menopause

Welcome to So What’s The Menopause?

Menopause is a natural physiological event experienced by all women. Menopausal symptoms generally commence in the 40s but can also affect younger women. During menopause, the ovaries progressively weaken and eventually cease egg production, leading to a decrease in oestrogen and progesterone levels. This hormonal reduction results in various physical and mental changes.

Stage 1: Perimenopause

The first stage is Perimenopause. This phase typically lasts 3 to 5 years and marks the transitional period preceding menopause. Oestrogen levels begin to decline, and symptoms may be misattributed to other health issues, often leaving women unaware that perimenopause has begun. Irregular periods are frequently the initial indication of menopause. Other symptoms may include:

  • Weight gain
  • Hot flashes
  • Night sweats
  • Cognitive difficulties (commonly referred to as brain fog)
  • Sleep disturbances
  • Headaches
  • Musculoskeletal discomforts
  • Gastrointestinal changes
  • Anxiety and irritability
  • Vaginal dryness
  • Loss of muscle mass

Perimenopause is often considered the most challenging stage of menopause, as it involves significant transitions in a woman’s body and mind.

Stage 2: Menopause

The second stage is Menopause, with the average onset age being 51. Menopause is diagnosed following 12 consecutive months without menstruation. At this stage, oestrogen levels are low, and the symptoms resemble those experienced during perimenopause, and can also include:

  • Vaginal dryness
  • Loss of libido
  • Increased risk of urinary infections

Stage 3: Postmenopause

Postmenopause is the final stage and persists throughout the remainder of a woman’s life. Symptoms from perimenopause and menopause typically lessen during this stage, although the risks of osteoporosis and heart disease increase.
