The basics of Menopause

Published: April 28, 2026

Menopause is the point in a woman’s life when menstruation stops permanently, marking the end of ovarian reproductive function. It is defined retrospectively after 12 consecutive months without a menstrual period. The average age of menopause in the U.S. is 51, though it commonly occurs between ages 45 and 55.

Understanding what is happening in your body can help normalize the experience. Menopause is a natural biological transition, but symptoms and health risks vary widely. It’s important to track changes in your menstrual cycle and discuss any concerns with your clinician.

Common Symptoms During the Menopause Transition

Symptoms often begin during perimenopause (the years leading up to menopause) and can fluctuate:

Changes in menstrual cycle (irregular timing, flow changes)
Hot flashes and night sweats (vasomotor symptoms)
Sleep disturbances
Mood changes, including irritability, anxiety, or low mood
Vaginal dryness and discomfort
Changes in sexual desire or arousal
Joint and muscle aches
Formication (“crawling” skin sensations)
Headaches
Cognitive changes (memory and concentration difficulties)
Heart palpitations
Fatigue
Skin and hair changes
Dry eyes
Body composition changes (increased abdominal fat)

Long-Term Health Considerations

Declining estrogen levels are associated with increased risk for:

Cardiovascular disease (the leading cause of death in women)
Osteoporosis and fracture risk
Genitourinary syndrome of menopause (GSM), including vaginal dryness, urinary urgency, and incontinence

How Menopause Is Diagnosed

For most women over age 45, menopause is diagnosed clinically based on symptoms and menstrual history. Lab testing is usually not necessary.

Your clinician will:

Review your menstrual pattern (including skipped periods)
Assess symptoms
Perform a physical exam when indicated
Rule out other causes of missed periods (e.g., thyroid disorders, pregnancy, hyperprolactinemia)

Hormone Testing: What’s Helpful and What’s Not

Hormone levels fluctuate significantly during perimenopause, so a single test can be misleading.

FSH (Follicle-Stimulating Hormone):

FSH rises as ovarian function declines
Levels >30 IU/L may suggest menopause, but are not definitive
Not routinely recommended to diagnose menopause in women over 45
May be useful in younger women (<45) with suspected early menopause

Estradiol:

Low estradiol levels support decreased ovarian function
Like FSH, levels fluctuate and are not routinely needed for diagnosis

Testing that is NOT recommended for diagnosing menopause:

Salivary hormone tests
Over-the-counter urine or at-home hormone kits
Vaginal pH testing alone

Treatment Options

Management should be individualized based on symptoms, health risks, and patient preferences.

Lifestyle approaches:

Regular physical activity (including strength training)
Balanced nutrition with adequate calcium and vitamin D
Smoking cessation
Limiting alcohol
Stress management and sleep hygiene

Hormone Therapy (HT):

The most effective treatment for hot flashes and GSM
Appropriate for many healthy women under age 60 or within 10 years of menopause onset
Requires individualized risk assessment and shared decision-making

Nonhormonal prescription options:

Certain SSRIs (Selective Serotonin Reuptake Inhibitors) e.g., paroxetine / SNRIs (Serotonin-Norepinephrine Reuptake Inhibitors) e.g., venlafaxine
Elinzanetant and fezolinetant are non-hormonal neurokinin-3 receptor antagonists approved for treating moderate to severe hot flashes associated with menopause
Gabapentin or clonidine (in select cases)

Genitourinary symptoms:

Vaginal estrogen (low-dose, local therapy)
Vaginal DHEA or oral ospemifene

Over-the-counter and complementary approaches:

Lubricants and moisturizers for vaginal dryness
Some women explore supplements (e.g., soy, black cohosh), though evidence for effectiveness is mixed and product quality varies

All treatment decisions should be made in partnership with a knowledgeable clinician, with ongoing evaluation of benefits and risks.
