At What Age Does Menopause Begin: Age and How Long It Lasts

Menopause is not a disease or a sudden event, but a gradual transition that every woman with menstruation goes through. Understanding at what age menopause begins and how long it lasts helps you take changes in your cycle and body more calmly. Let's look at what age menopause usually begins and how its stages progress.

What menopause and the climacteric are

Menopause is the time when menstruation stops and pregnancy becomes impossible. Doctors consider menopause to have occurred if 12 months have passed without a period. The period before this point is called the menopausal transition, or perimenopause: the ovaries produce less estrogen and progesterone, and this causes symptoms. The climacteric itself is a natural part of life, not a condition that necessarily requires treatment.

At what age menopause begins

Most often menopause occurs between the ages of 45 and 55. According to various data, the average age is about 47.5 years, and menopause usually occurs between 49 and 52 years. The transition to menopause often begins as early as age 40, but sometimes earlier. That is, the question "at what age does menopause begin in women" does not have one exact date: each woman has her own timing within these boundaries.

What determines the age at which menopause begins

The age of menopause is individual. Timing is influenced by smoking, a family history of early or premature menopause, and certain diseases. Menopause may occur earlier after surgery to remove both ovaries, as well as after chemotherapy or hormonal treatment for breast cancer. Removal of the uterus alone stops menstruation but does not cause menopause if the ovaries are preserved.

How long menopause lasts and its stages

Perimenopause can last from four to eight years; according to other descriptions, several years, sometimes up to eight. During this time, cycles become irregular: shorter by 2–7 days, longer, lighter or heavier. Estrogen levels are on average 20–30% lower than before the transition, with noticeable fluctuations. Hot flashes usually last from 30 seconds to ten minutes and often stop after a year or two. The severity of symptoms varies among women.

• Changes in the menstrual cycle: irregularity, varying duration and flow.
• Hot flashes and night sweats.
• Vaginal dryness, discomfort during intercourse.
• Sleep disturbances, mood swings, anxiety.
• Urinary incontinence, joint pain, reduced energy.

When menopause occurs earlier than expected

If menopause occurs before age 40, it is called premature, and before age 45, early. This can happen without a known cause, after removal of the ovaries, due to chemotherapy or hormonal treatment. Primary ovarian insufficiency is distinguished separately: the ovaries stop working normally before age 40, but menstruation may persist, and pregnancy is sometimes still possible.

When to see a doctor

The diagnosis of menopause is usually made based on menstrual history; if necessary, the doctor may assess hormone levels in blood or urine. You can discuss cycle changes, symptoms, and ways to relieve them with your doctor at any time. In postmenopause, any genital bleeding is an alarming symptom that requires evaluation to rule out malignant diseases.

The onset of menopause itself is not a reason to call emergency services; 103 or 112 — if there are signs of stroke or heart attack, such as chest pain.
