What Is Menopause? A Plain-English Guide to the Transition

Menopause is a single day — the day that marks 12 consecutive months without a menstrual period. The average age in the US is 51. Everything before it is perimenopause; everything after is postmenopause, which you'll live in for roughly a third of your life.

What's actually happening

Your ovaries stop releasing eggs and dramatically reduce estrogen, progesterone and testosterone production. Estrogen receptors live in nearly every tissue — brain, bone, heart, skin, gut, vagina, bladder, joints — which is why symptoms are so wide-ranging.

Most common symptoms

• Hot flashes and night sweats
• Sleep disruption
• Vaginal dryness and painful sex
• Recurrent UTIs
• Brain fog and memory blips
• Mood changes, anxiety, low motivation
• Weight gain and changing body composition
• Bone density loss (silent — labs are critical)
• Skin and hair changes

How long it lasts

Vasomotor symptoms (hot flashes) average 7–10 years. Genitourinary symptoms (vaginal, bladder) are progressive and lifelong without treatment. Bone and cardiovascular changes are also permanent without intervention.

Modern hormone therapy

The Menopause Society's 2022 position statement is clear: for healthy women within 10 years of menopause and under 60, the benefits of hormone therapy outweigh the risks. The best menopause doctors use transdermal bioidentical estradiol, oral micronized progesterone, vaginal estrogen and, where appropriate, testosterone.
