Read about when menopause starts, the factors that can trigger it, and how long it lasts.

Sep 20, 2023 By Nancy Miller

For many women, "menopause" means the end of menstruation and fertility. Menopause is a multi-step process. The transition might take years, including pre-, menopausal, and post-menopause. People often ask, "How long does menopause last?"

What is Menopause?

Menopause happens after 12 months without menstruation. This makes her post-menopausal. Pre- or perimenopause symptoms and hormonal changes start earlier. Perimenopause is the transitional time preceding menopause, while pre-menopause is reproductive years. Perimenopause causes irregular menstruation, hot flashes, sleep problems, mood changes, and vaginal dryness due to estrogen and progesterone fluctuations.

Menopause Transition

Menopause usually occurs at 51. However, it can happen in the early 40s or late 50s. Genetics, smoking, and medical problems can cause it. Women may encounter more menopausal symptoms when estrogen levels drop. Periods may become more frequent or farther apart during this time.

When Does Menopause Start?

Menopause marks the end of a woman's reproductive years. The timing varies, but the sensation is universal. Westerners average 51 years old for menopause. This is not a defined age, and several circumstances might accelerate or postpone menopause. Explore these influential factors.

1. Genetics

Family history significantly impacts menopause onset. A woman's genetics can reveal when she may undergo this change. If your mother, maternal aunts, or sisters started menopause early, you may too. Research reveals that genes from both parents can affect menopause time. Thus, tracing your family's female menopause age may reveal your path. Genetics is important, but environmental and behavioral variables are equally important.

2. Smoking

Smoking has widespread negative impacts beyond respiratory and cardiovascular health. Cigarette smoke contains chemicals that harm ovaries and estrogen production. Regular smoking causes menopause earlier, according to numerous research. Smoking can cause menopause one to two years early. Tobacco compounds may accelerate ovarian follicle loss, causing this premature beginning. Smoking causes an earlier onset and may worsen menopausal symptoms like hot flashes.

3. Ethnicity

Ethnicity can subtly influence the age of menopause onset. While the underlying reasons are still being studied, cultural, genetic, and environmental factors unique to different racial and ethnic groups might be contributors. Some research suggests that Hispanic and African-American women might embark on their menopausal transition slightly earlier than their Caucasian counterparts. On the other hand, Asian women might experience it a tad later. These differences, while intriguing, are not drastically divergent from the average but are essential considerations in understanding the broad spectrum of menopausal experiences.

4. Chemotherapy and Radiation

Cancer treatments, especially chemotherapy and radiation, can profoundly affect a woman's reproductive system. These treatments target rapidly dividing cells, a category to which cancer cells belong. However, the ovaries' cells responsible for producing eggs also fall into this rapidly dividing category. As a result, chemotherapy and radiation can damage the ovaries, leading to a drop in estrogen levels and triggering early or immediate menopause.

Symptoms might appear suddenly and be more severe than natural menopause. It's also worth noting that the onset of menopause due to cancer treatments can be temporary or permanent, depending on the treatment type, dosage, and the woman's age.

5. Surgical Removal

Bilateral oophorectomy may be needed for some diseases or malignancies. Since the ovaries produce estrogen and progesterone, their loss causes a dramatic drop. Thus, menopause and associated symptoms begin immediately for a woman. Natural menopause is less intense than ' surgical menopause,' a fast change. This surgery will affect women's short- and long-term health, so they should be prepared.

Symptoms and Their Duration

A gamut of symptoms often accompanies menopause. Some of the common ones include:

  • Hot flashes: Sudden feelings of warmth that can cause redness and sweating.
  • Night sweats: Hot flashes occurring at night, leading to disrupted sleep.
  • Vaginal dryness: Reduced estrogen levels can cause the vaginal walls to become thinner and dryer.
  • Mood changes: Fluctuating hormone levels can contribute to mood swings or depressive symptoms.
  • Weight gain: Metabolism often slows during this transition, leading to weight gain.
  • Reduced bone density: With a decline in estrogen, bones might weaken, heightening the risk of osteoporosis.

The intensity and duration of these symptoms vary. Some might last only a few months, while others could experience them for over a decade. Perimenopausal symptoms can start in the late 30s or early 40s and persist into the postmenopausal phase.

How Long Does Menopause Last?

Understanding menopause's duration requires navigating its many stages, each with its chronology and symptoms. Many women approaching menopause ask, "How long does menopause last?" out of curiosity and anxiety. Menopause is as unique as the woman living through it, so giving a single response is difficult.

Perimenopause, the beginning of menopause, is first. This phase precedes menopause and usually begins in the 40s, but it may start earlier in particular women. Perimenopause reduces estrogen production, causing irregular menstrual cycles. These anomalies frequently signal menopause. Perimenopause lasts an average of 4 years. However, some women have experienced it for a decade. This period can cause mood swings, heat flashes, sleep difficulties, and vaginal dryness, which worsen with menopause.

After perimenopause, menopause begins with a 12-month interval without periods. It marks the conclusion of a woman's reproductive years. This milestone doesn't necessarily eliminate menopausal symptoms.

Many women wonder if they will finally find relief from perimenopause symptoms after menopause. Many acute symptoms, like hot flashes, fade over time, but some might linger or occur throughout post-menopause. Genetics, health, lifestyle, and previous surgery can affect these symptoms' type, intensity, and duration. Some women's symptoms may last a decade or longer after menopause, while others may fade altogether.

Managing Menopause

Though natural, menopause symptoms can be difficult. Here are several remedies:

  • Use Hormone Replacement Therapy (HRT). Post-menopause hormone replacement with medicines. Many find it effective, but there are hazards.
  • Black cohosh, phytoestrogens, and other supplements help some women. Always consult a doctor before commencing treatment.
  • Exercise, a balanced diet, stress management, and avoiding hot foods and caffeine can reduce symptoms.
  • Postmenopause screenings for osteoporosis, heart disease, and other illnesses are essential.
