Menopause

Introduction

  • Menopause marks the permanent cessation of menstrual periods, occurring 12 months after the last period.
  • It is a natural biological process typically occurring between the ages of 45–55, signifying the end of reproductive years.
  • Menopause can cause a variety of symptoms due to hormonal changes, particularly a decline in estrogen and progesterone levels.
  • Management includes lifestyle adjustments, hormone replacement therapy (HRT), and non-hormonal treatments to improve quality of life.

Phases of Menopause

  1. Perimenopause
    • Transitional phase leading up to menopause.
    • Hormone levels fluctuate, causing irregular periods and symptoms like hot flashes.
  2. Menopause
    • Defined retrospectively after 12 consecutive months without a period.
  3. Postmenopause
    • The period after menopause, when symptoms may persist but hormonal fluctuations stabilize.

Causes of Menopause

  1. Natural Decline of Reproductive Hormones
    • Ovaries gradually reduce production of estrogen and progesterone.
  2. Surgical Menopause
    • Removal of ovaries (oophorectomy) causes immediate menopause.
  3. Medical Treatments
    • Chemotherapy or radiation therapy can damage ovarian function.
  4. Primary Ovarian Insufficiency
    • Premature menopause occurring before age 40 due to genetic or autoimmune factors.

Symptoms of Menopause

  1. Physical Symptoms
    • Hot flashes and night sweats.
    • Vaginal dryness and discomfort during intercourse.
    • Fatigue and joint aches.
  2. Emotional Symptoms
    • Mood swings, anxiety, and depression.
    • Difficulty concentrating and memory issues (brain fog).
  3. Long-Term Effects
    • Bone loss (osteoporosis).
    • Increased risk of cardiovascular disease.
    • Weight gain and changes in body composition.

Complications of Menopause

  • Osteoporosis: Increased risk of fractures due to bone density loss.
  • Cardiovascular Disease: Loss of estrogen raises LDL cholesterol and lowers HDL cholesterol.
  • Urogenital Atrophy: Vaginal dryness, urinary incontinence, and recurrent urinary tract infections.
  • Mental Health Issues: Anxiety, depression, and cognitive decline.

Diagnosis of Menopause

  1. Clinical Diagnosis
    • Based on symptoms and history of amenorrhea for 12 months.
  2. Laboratory Tests (if needed)
    • FSH Levels: Elevated follicle-stimulating hormone (>30 IU/L) indicates menopause.
    • Estradiol Levels: Decreased levels of estrogen.
    • Thyroid Tests: Rule out thyroid dysfunction.
  3. Bone Density Scan (DEXA)
    • Recommended for postmenopausal women at risk of osteoporosis.

    • Over-the-counter products to relieve dryness.

Monitoring Parameters

  • Regular monitoring of symptom severity and quality of life.
  • Bone density scans every 1–2 years for high-risk women.
  • Cardiovascular health monitoring (lipid profile, blood pressure).
  • Breast exams and mammograms if on HRT.

Patient Counseling Points

  • Discuss the risks and benefits of HRT and alternative treatments.
  • Emphasize the importance of a balanced diet and physical activity.
  • Encourage regular health check-ups for bone and heart health.
  • Educate on recognizing early signs of complications, such as chest pain or unusual bleeding.

Use in Women with Premature Menopause

  • HRT is often recommended until the natural age of menopause to prevent complications.

Use in Women with a History of Cancer

  • Non-hormonal treatments are preferred to manage symptoms.

Use in Elderly Women

  • Focus on managing long-term effects like osteoporosis and cardiovascular risks.
