Understanding the stages
of hormonal transition

Hormonal health changes throughout adult life, with key stages in the journey.


These are the reproductive years, perimenopause, the menopause milestone and postmenopause.


Each stage can bring different hormonal shifts, symptoms and health considerations.

A natural progression.  Clearly understood.

The reproductive years — an established hormonal cycle

The reproductive years begin with the first menstrual period and continue until perimenopause begins. During this time, ovarian hormones follow a cyclical pattern that supports menstruation, ovulation and fertility.

Common experiences

  • Regular menstrual cycles

  • Premenstrual symptoms

  • Period pain or heavy bleeding

  • Changes related to contraception

  • Fertility and pregnancy considerations

 

Common concerns during the reproductive years

  • What are PMS and PMDD?

  • Is my contraception right for me?

  • Could I have PCOS/PMOS?

An established cycle. Care throughout adult life.

Perimenopause — the start of the menopause journey

Perimenopause is the stage when a woman's hormone levels begin to fluctuate as the ovaries gradually produce less oestrogen and progesterone. This stage usually begins in the 40s but can start earlier.

Common experiences

  • Changes to menstrual cycles

  • Hot flushes and night sweats

  • Sleep disturbances

  • Brain fog and difficulty concentrating

  • Mood changes

Early changes. Recognised and supported.

The menopause milestone — a single point in time

Menopause is the point in time when a woman has gone 12 consecutive months without a menstrual period. It marks the end of natural fertility and reflects the permanent decline in ovarian hormone production.

Common experiences

  • Hot flushes and night sweats

  • Sleep disruption

  • Anxiety or mood changes

  • Vaginal dryness

  • Joint pain

A defined milestone. Care continues.

Postmenopause — life after menopause

Postmenopause refers to the years following the menopause milestone. Hormone levels remain low, and some symptoms may improve while others, such as vaginal dryness or bone changes, may persist or worsen.

Health considerations after menopause

  • Bone health

  • Genitourinary syndrome of menopause

  • Urinary tract infections

  • Skin and hair changes

  • Weight and metabolic changes
