Perimenopause

The decade before menopause

A real physiological transition.

Perimenopause usually starts in the mid-to-late 40s (sometimes earlier) and often lasts about four to eight years, longer if it begins earlier. Hormone levels fluctuate. How you feel can sit a long way from “how you look on paper”. Face-to-face at The Richmond House Clinic, Penarth, and video consultations for the UK.

Common symptoms and common pitfalls

What women often notice

  • Irregular or changing periods
  • Hot flushes and night sweats
  • Sleep disturbance and fatigue
  • Anxiety, irritability or low mood
  • Brain fog and poor concentration
  • Central weight change and joint aches

What the consultation holds

  • Not dressing symptoms up as “just ageing”
  • Sleep treated as a foundation, not an extra
  • Resistance training over “eat less, more cardio”
  • Blood sugar volatility and stress physiology
  • Looking for overlap: thyroid, iron, sleep apnoea
  • HRT discussed where it belongs, not assumed

Lifestyle medicine sits beside medical treatment

Some women do well with lifestyle interventions alone. Others benefit from hormonal or non-hormonal therapies. The aim is not to “biohack hormones”. It is to reduce symptom burden, protect cardiometabolic and bone health, and write a plan that matches your risk profile and values.

Start with the four-levers map in the Journal — muscle, protein, sleep and a plan that fits you. The navigating note and the older symptoms guide are still there if you want more clinic context.
