What are the three stages of menopause?

Natural menopause denotes the permanent cessation of menstruation without medical intervention. It unfolds gradually through three phases:

• Perimenopause or "menopause transition": Typically starting in the 40s, perimenopause spans 8 to 10 years before menopause. During this period, estrogen production decreases gradually, leading to irregular menstrual cycles. Menopause symptoms may emerge, although pregnancy is still possible as ovulation occurs sporadically.
• Menopause: Defined by 12 consecutive months without menstruation, menopause signals the end of ovulation and significant estrogen production. It marks a clear transition into postmenopause.
• Postmenopause: This phase begins after one year without periods. While some menopausal symptoms may diminish, the reduced estrogen levels elevate the risk of conditions like osteoporosis and heart disease. Symptoms can persist for a decade or more into postmenopause.

What is the normal age for menopause?

The average age for menopause onset in the United States is around 51 years. However, the journey towards menopause typically commences during the mid-40s.

What are the signs of menopause?

You might be transitioning into menopause if you experience some or all of the following symptoms:

• Hot flashes (a sudden feeling of warmth spreading over your body).
• Night sweats and/or cold flashes.
• Vaginal dryness causing discomfort during sex.
• Urinary urgency (a frequent need to urinate).
• Difficulty sleeping (insomnia).
• Emotional changes (irritability, mood swings, or mild depression).
• Dry skin, dry eyes, or dry mouth.
• Breast tenderness.
• Worsening premenstrual syndrome (PMS).
• Irregular periods or periods that are heavier or lighter than usual.

Additionally, some people might experience:

• Racing heart (heart palpitations).
• Headaches.
• Joint and muscle aches and pains.
• Changes in libido (sex drive).
• Difficulty concentrating or memory lapses (often temporary).
• Weight gain.
• Hair loss or thinning.

These symptoms are caused by changes in hormone levels. The intensity of menopause symptoms varies; some people may have intense symptoms, while others experience mild symptoms. Not everyone will have the same symptoms during the transition to menopause.

How long do you have symptoms of menopause?

Menopause symptoms can last up to 10 years, but most people experience them for less than five years.

Why does menopause happen?

When menopause occurs naturally, it is a normal part of aging. It is defined as going a full year without menstrual bleeding, without any medical intervention such as hormonal birth control, radiation therapy, or surgical removal of the ovaries. As you age, your reproductive cycle, which has been active since puberty, begins to slow down and eventually stops. Approaching menopause, your ovaries produce less estrogen, leading to changes in your menstrual cycle, which becomes irregular before stopping altogether.

Your body undergoes physical changes as it adjusts to the new hormone levels. The symptoms experienced during perimenopause, menopause, and postmenopause are part of this adaptation process.

What hormonal changes happen during menopause?

The changes typically associated with “menopause” occur when your ovaries stop producing high levels of hormones. Your ovaries, which are reproductive glands, store and release eggs and produce the hormones estrogen and progesterone. These hormones regulate menstruation, with estrogen also playing a crucial role in calcium utilization and cholesterol maintenance in your blood.

As you approach menopause, your ovaries cease releasing eggs, leading to your final menstrual cycle.
