Menopause: Symptoms, Stages and a Guide to Improving Quality of Life

What Is Menopause?

Hello, I am Dr. Emre Gecer. Menopause means the permanent cessation of menstrual cycles and is diagnosed retrospectively after 12 consecutive months without a menstrual period following the last menstrual bleeding. Menopause is a natural and inevitable physiological phase in a woman's life; it is not a disease. In Turkey and globally, the average age of menopause is 51, but it can occur over a wide range of 45-55 years.

Menopause that develops before age 40 is called premature ovarian insufficiency (POI) and requires special evaluation. Menopause between ages 40-45 is defined as early menopause.

Stages of Menopause

The menopause process is divided into three main stages, each with its own hormonal and clinical features:

1. Perimenopause (Menopausal Transition)

Perimenopause covers the period from the beginning of the menopausal transition through the year following the last menstrual period. It usually begins in the mid-40s and lasts on average 4-8 years. During this period ovarian function gradually declines:

• Menstrual irregularities begin: cycles become longer or shorter, bleeding increases or decreases
• Estrogen levels fluctuate — sometimes very high, sometimes very low
• Ovulation becomes irregular but does not stop completely; therefore pregnancy is still possible
• Symptoms such as hot flashes and sleep disturbance may begin during this period
• FSH (follicle-stimulating hormone) levels begin to rise

2. Menopause

Defined as the point in time of the final menstrual period. The diagnosis is made when 12 months of amenorrhea (no menstruation) have elapsed since the last menstrual period. At this point the ovaries no longer produce functional eggs and estrogen levels have fallen markedly.

3. Postmenopause

The period that begins 12 months after the last menstrual period and covers the rest of life. Estrogen levels remain low. The effects of long-term estrogen deficiency (bone loss, increased cardiovascular risk, urogenital atrophy) become more apparent during this phase.

Hormonal Changes

Menopause is fundamentally driven by depletion of ovarian follicles and the associated hormonal changes:

• Estrogen decline: Estradiol (the main form of estrogen) produced by the ovaries falls significantly. In the postmenopausal period, estrogen production occurs mainly through conversion from androgens in adipose tissue (via the aromatase enzyme); however, this level is much lower than the premenopausal level.
• Progesterone decline: When ovulation stops, progesterone production drops to almost zero
• FSH increase: The pituitary gland raises FSH secretion to compensate for falling estrogen. A serum FSH level >40 IU/L supports the menopausal transition.
• LH increase: Rises similarly to FSH
• Androgen changes: Ovarian-derived androgens fall but adrenal androgens continue

Symptoms of Menopause

Vasomotor Symptoms

• Hot flashes: The most characteristic symptom of menopause. 75-80% of women experience them. Characterized by an intense feeling of heat suddenly spreading across the face, neck and upper chest, with flushing and sweating. Usually lasts 1-5 minutes but can be longer in some women. Hot flashes are related to disturbance of the hypothalamic thermoregulatory center due to falling estrogen.
• Night sweats: The night-time form of hot flashes. They occur with intense sweating, soaking of bed linen and waking from sleep. They severely impair sleep quality.

Urogenital Symptoms

• Vaginal dryness: Thinning of the vaginal mucosa (atrophy) due to estrogen deficiency and reduced lubrication. Leads to pain during sex (dyspareunia) and itching.
• Urinary symptoms: Susceptibility to urinary tract infections, frequent urination, urinary urgency, stress incontinence (leaking urine when coughing or sneezing)

Psychological and Neurological Symptoms

• Mood changes: Irritability, anxiety, sadness, emotional fluctuations. Estrogen plays a role in the metabolism of mood-regulating neurotransmitters such as serotonin and norepinephrine.
• Sleep disturbance: Difficulty falling asleep, frequent waking, early waking. May occur both due to night sweats and independently.
• Difficulty concentrating and forgetfulness: Subjective decline in cognitive function, word-finding difficulty. Usually transient.
• Decreased libido: Related to both hormonal changes and to vaginal dryness and psychological factors

Long-Term Health Effects

• Bone loss (osteoporosis risk): Estrogen is the most important hormone suppressing bone resorption (osteoclast activity). In the first 5-7 years after menopause accelerated bone loss occurs; up to 20% of total bone density may be lost in this period. This markedly increases the risk of osteoporosis and fractures.
• Increased cardiovascular risk: In the premenopausal period estrogen is cardioprotective (raises HDL cholesterol, lowers LDL, protects vascular endothelium). After menopause this protection is lost and cardiovascular disease risk rises rapidly in women; in postmenopausal women coronary artery disease risk approaches that of men.
• Skin and hair changes: Skin thinning, dryness and increased wrinkling due to collagen loss. Hair thinning and shedding.
• Weight gain: Slowing of metabolic rate and changes in fat distribution (tendency to accumulate around the abdomen)

Diagnosis

The diagnosis of menopause is mostly clinical. In a woman over 45 who has not had a period for 12 months or more and has typical symptoms, additional laboratory testing is generally not necessary. However, hormonal tests are done in the following situations:

• Suspected menopause under age 40 (premature ovarian insufficiency)
• Assessment of early menopause between ages 40-45
• Determining menopause in women using hormonal contraception
• In women who have had a hysterectomy (removal of the uterus)

In such cases, FSH levels are measured; consecutive measurements >40 IU/L support menopausal transition. TSH (thyroid function) and other endocrine tests may be done for differential diagnosis.

Treatment and Management Strategies

1. Lifestyle Changes

Lifestyle modifications form the foundation of treatment for managing menopausal symptoms:

• Regular exercise: At least 150 minutes per week of moderate-intensity aerobic exercise (walking, swimming, cycling) and resistance/weight training 2-3 days per week. Exercise reduces hot flashes, improves sleep quality, lifts mood, protects bone health and reduces cardiovascular risk.
• Dietary adjustment: Foods rich in calcium and vitamin D, Mediterranean diet, soy-based foods (because of their phytoestrogen content), whole grains, vegetables and fruits. Caffeine, alcohol and spicy foods may trigger hot flashes.
• Stress management: Yoga, meditation, deep-breathing exercises, cognitive behavioral therapy
• Sleep hygiene: Regular sleep schedule, keeping the bedroom cool, limiting screen time
• Smoking cessation: Smoking accelerates menopause and worsens bone loss

2. Hormone Replacement Therapy (HRT)

HRT is the most effective treatment for menopausal symptoms. It reduces hot flashes and night sweats by 75-90%, treats vaginal atrophy and prevents bone loss.

HRT types:

• Estrogen alone (ET): Used in women who have had a hysterectomy (uterus removed)
• Combined estrogen + progesterone (EPT): In women with an intact uterus, progesterone is added to prevent estrogen-related endometrial hyperplasia and cancer risk
• Routes of administration: Oral tablets, transdermal (skin) patches, gels, vaginal creams/rings, sprays

Benefits and risks of HRT:

The Women's Health Initiative (WHI) study and subsequent analyses have shown that the timing of HRT is critical. HRT started within the first 10 years of menopause onset or before age 60 (the timing hypothesis):

• Effectively treats vasomotor symptoms
• Reduces the risk of bone fractures
• May provide cardiovascular protection
• May reduce the risk of colorectal cancer

Potential risks:

• Breast cancer risk: A small increase with combined HRT used for more than 5 years (fewer than 1 additional case per 1000 women per year)
• Venous thromboembolism risk: Increases with oral forms; this risk is markedly lower with transdermal forms
• Stroke risk: Slight increase with oral forms

The decision to use HRT should be individualized based on each woman's risk profile, symptom severity, preferences and comorbidities.

3. Non-Hormonal Treatment Options

Alternative treatments are available for women who cannot use HRT or prefer not to:

• SSRI/SNRI antidepressants: Paroxetine (FDA-approved), venlafaxine, escitalopram. Can reduce hot flashes by 40-60%.
• Gabapentin and pregabalin: Effective for hot flashes and sleep disturbance
• Clonidine: An alpha-2 adrenergic agonist; may reduce hot flashes
• Fezolinetant: A new non-hormonal treatment, an NK3 receptor antagonist, approved for hot flashes
• Vaginal moisturizers and lubricants: Can be used as an alternative to HRT for vaginal dryness
• Low-dose vaginal estrogen: Unlike systemic HRT it provides only local effect and is effective for urogenital symptoms

4. Herbal and Complementary Approaches

• Soy isoflavones and phytoestrogens: Some studies have shown mild positive effects on hot flashes
• Black cohosh: The most studied herbal product for hot flashes; efficacy is debated but it is considered safe for short-term use
• Acupuncture: Some women report positive effects on hot flashes and sleep quality

It should be remembered that herbal products may have drug interactions and standardization can be a problem; consulting a doctor before use is important.

Bone Health: Osteoporosis Prevention

Postmenopausal osteoporosis is a serious health problem. To protect bone health:

• DEXA scan: Bone density measurement (DEXA) is recommended for all women over 65 and for younger women with risk factors
• Calcium intake: 1000-1200 mg per day (primarily from foods: milk, yogurt, cheese, dark leafy greens, almonds)
• Vitamin D: 800-1000 IU per day (supplementation may be needed especially in people with limited sun exposure)
• Weight-bearing exercise: Walking, stair climbing, dancing, light weight training maintain bone density
• Fall prevention: Home modifications, balance exercises, appropriate footwear
• Pharmacological treatment: When indicated, drugs such as bisphosphonates (alendronate, risedronate), denosumab or raloxifene are used

Cardiovascular Health

After menopause, cardiovascular disease is the leading cause of death in women. For cardiovascular protection:

• Regular monitoring of blood pressure, cholesterol and blood sugar
• Healthy diet (Mediterranean diet)
• Regular physical activity
• Healthy weight management
• Smoking cessation
• When indicated, antihypertensive and statin therapy

Conclusion

Menopause is a natural process that every woman will experience, and with correct information, support and treatment it can be managed in a healthy way while preserving quality of life. Being aware of symptoms from the perimenopausal period, adopting lifestyle changes, protecting bone and cardiovascular health and seeking medical support when needed are all very important. Every woman's menopause experience is different; treatment decisions should therefore be personalized based on individual assessment. Menopause is not an end but a new beginning — living a healthy and active life is entirely within your control.

Wishing you healthy days.
