What Is Perimenopause? Signs, Science & Natural Support with MENO

🧠 What Is Perimenopause? Signs, Science & Natural Support with MENO

What is Perimenopause means β€œaround menopause” β€” it’s the transitional phase leading up to menopause, when the ovaries gradually produce less estrogen and progesterone.

It usually begins in the mid-to-late 40s but can start earlier, lasting anywhere from a few months to over a decade. Perimenopause ends 12 months after your final period, when menopause officially begins.


πŸ”¬ The Biological Changes

During perimenopause, ovarian follicles are still present β€” but their number and quality are declining. The ovaries respond less consistently to follicle-stimulating hormone (FSH) and luteinising hormone (LH), leading to:

  • Irregular ovulation

  • Fluctuating estrogen and progesterone levels

  • Cycles that may be longer, shorter, or skipped entirely

Unlike menopause, where estrogen is consistently low, perimenopause is marked by hormonal swings β€” meaning symptoms can appear and disappear unpredictably.


🧠 Why Hormone Fluctuations Cause Symptoms

Estrogen and progesterone influence much more than reproductive health. Changing levels can affect:

  • 🌑 Thermoregulation β€” sudden hot flushes or night sweats

  • 🧠 Mood & focus β€” shifting serotonin and dopamine activity

  • 😴 Sleep patterns β€” changes in melatonin production and stress hormones

  • ❀️ Cardiovascular health β€” altered lipid balance and blood vessel function

  • 🦴 Bone density β€” slower calcium absorption, setting the stage for osteoporosis later


πŸ“‹ Common Signs of Perimenopause

  • Irregular periods

  • Hot flushes or night sweats

  • Mood swings or increased anxiety

  • Trouble sleeping

  • Brain fog or difficulty concentrating

  • Reduced libido

  • Hair or skin changes
