Early Signs of Perimenopause
Many women begin experiencing symptoms of perimenopause years before their periods stop, often during their early to mid‑40s. Perimenopause is the transition leading up to menopause, when hormone levels such as oestrogen and progesterone begin to fluctuate. These hormonal changes can affect many systems in the body and may lead to a range of symptoms including sleep changes, anxiety, brain fog, irregular periods and weight changes. Recognising the early signs of perimenopause can help women better understand what may be happening in their bodies and seek appropriate support if symptoms begin to affect daily life.
Early Symptoms of Perimenopause
The early symptoms of perimenopause can vary widely between women. Some women notice only mild changes, while others experience symptoms that significantly affect sleep, mood or energy levels.
Common early signs include:
Changes in menstrual cycles
Periods may become irregular, heavier or lighter, or the time between cycles may change.
Sleep disruption
Many women notice waking in the early hours of the morning or difficulty staying asleep.
Hot flushes and night sweats
Hormonal fluctuations can affect the body’s temperature regulation.
Anxiety or mood changes
Some women notice increased anxiety, irritability or mood fluctuations.
Brain fog and difficulty concentrating
Memory lapses or trouble focusing are frequently reported during perimenopause.
Fatigue
Persistent tiredness can occur, sometimes related to disrupted sleep.
Weight changes
Some women notice increased weight gain, particularly around the abdomen.
Reduced libido
Hormonal changes can affect sexual desire and arousal.
Joint aches or stiffness
Changes in oestrogen levels may influence joint health and inflammation.
Why do these symptoms occur?
During perimenopause the ovaries gradually begin producing hormones less consistently. Levels of oestrogen and progesterone can fluctuate significantly from month to month.
These hormonal fluctuations affect multiple body systems, including the brain, metabolism, sleep regulation and temperature control. As a result, symptoms may seem varied or unrelated.
When to Seek Support
For some women, symptoms are mild and manageable. For others, they can significantly affect sleep, mood, work and relationships.
Understanding the early signs of perimenopause can help women recognise what may be happening and consider appropriate strategies to support their health during this transition.
