Perimenopause marks a significant transition in a woman’s reproductive life, often accompanied by a range of symptoms that can affect quality of life. Understanding the underlying biological changes during this phase helps in identifying effective treatments tailored to individual needs. This article explores the pathophysiology of perimenopause, outlines common symptoms, and discusses treatment options with guidance on who may benefit most from each approach.
What Happens During Perimenopause
Perimenopause is the transitional period before menopause when ovarian function gradually declines. This phase can last several years, typically beginning in a woman’s 40s but sometimes earlier or later. Family history is important, so ask if haven't before. The hallmark of perimenopause is irregular hormone production, especially fluctuations in estrogen and progesterone levels. Thus evaluation of estrogen or progesterone levels are not part of an evidence based approach to diagnosis.
The ovaries produce less estrogen overall, but levels can spike unpredictably. Progesterone production decreases more steadily due to fewer ovulations. These hormonal shifts disrupt the menstrual cycle and trigger various physical and emotional symptoms.
Key Hormonal Changes
Estrogen fluctuations: Estrogen levels rise and fall irregularly, causing symptoms like hot flashes and mood swings.
Progesterone decline: Lower progesterone leads to irregular periods and heavier or lighter bleeding.
Follicle-stimulating hormone (FSH) increase: The pituitary gland releases more FSH to stimulate the ovaries, but the response weakens over time.
These changes affect multiple body systems, including the brain, cardiovascular system, bones, and skin.
Common Symptoms of Perimenopause
Symptoms vary widely among women but often include:
Irregular menstrual cycles: Periods may become unpredictable, heavier, or lighter.
Vasomotor symptoms; Hot flashes and night sweats: Sudden warmth, sweating, and flushing, often disrupting sleep. Vasomotor symptoms affect up to 80% of women and last an average of 7-8 years total, including 4-5 years after the final menstrual period
Mood changes: Anxiety, irritability, and depression can occur due to hormonal instability.
Sleep disturbances: Difficulty falling or staying asleep, often linked to night sweats.
Genitourinary syndrome of menopause affects up to 50% of women and is progressive without treatment, unlike vasomotor symptoms which may resolve spontaneously. Symptoms include vaginal dryness, irritation, painful intercourse (dyspareunia), and urinary issues like urgency and frequent UTIs, affecting sexual, vaginal, and urinary health
Decreased libido: Hormonal changes and physical symptoms can lower sexual desire.
Cognitive changes: Some women experience memory lapses or difficulty concentrating.
Physical changes: Weight gain, thinning hair, and changes in skin elasticity.
These symptoms result from the complex interplay of declining and fluctuating hormones affecting various organs and systems.
How Perimenopause Affects the Body
Brain and Mood
Estrogen influences neurotransmitters like serotonin and dopamine, which regulate mood and cognition. Fluctuating estrogen can cause mood swings, anxiety, and depression. Sleep disruption further worsens mental health.
Cardiovascular System
Estrogen protects blood vessels and maintains healthy cholesterol levels. Its decline increases the risk of hypertension, atherosclerosis, and heart disease.
Bones
Estrogen helps maintain bone density. Reduced levels accelerate bone loss, increasing osteoporosis risk.
Reproductive Organs
Lower estrogen and progesterone cause changes in the uterus and vagina, leading to irregular bleeding and vaginal dryness.
Treatment Options for Perimenopause Symptoms
Treatment aims to relieve symptoms, improve quality of life, and reduce long-term health risks. Options range from lifestyle changes to hormone therapy and non-hormonal medications. Our understanding of the benefits and risks of hormonal based treatment has dramatically changed over the past few years.
Hormone Therapy (HT)
You may have heard that the evidence based approach to treating perimenoapuse has changed and wonder why. This was due to the reevaluation of the 2002 Women's Health Initiative (WHI) study, which was originally misinterpreted as indicating higher risks than existed for younger, newly menopausal women. That doesnt mean that you have to treat with hormone replacement but its often the ideal choice for most women.
Hormone therapy replaces estrogen alone or combined with progesterone to stabilize hormone levels.
Who is a good candidate? Women under age 60 and within 10 years of menopause onset with moderate to severe symptoms are the best candidates, particularly those without contraindications or elevated cardiovascular or breast cancer risk
A moderate to severe symptom means your quality of life is altereted. I.E. If its bothering you.
Benefits: Effective relief of vasomotor symptoms, improved sleep, mood stabilization, and prevention of bone loss.
Risks: Potential increased risk of blood clots, stroke, and breast cancer depending on therapy type and duration. Careful evaluation and monitoring are essential.
Calculated 10-year ASCVD risk <5% for oral or transdermal therapy; 5-10% risk may consider transdermal estrogen preferentially.
The risk of a blood clot is less than the risk associated with oral contraceptives or pregancy in most women.
Women with prior hysterectomy can use estrogen alone; those with intact uterus require micronized progesterone or bazedoxifene to prevent endometrial hyperplasia.
Continuous progesterone use stops menstruation. Cyclic use allows for menstruation if you prefer.
Poor Candidates/Contraindications to HRT
Absolute contraindications include:
History of breast cancer or estrogen-sensitive endometrial cancer
Prior myocardial infarction, stroke, or TIA
Unexplained vaginal bleeding
Active liver disease
History of venous thromboembolism or pulmonary embolism (unprovoked or with high-risk thrombophilia)
ASCVD risk ≥7.5% (consider nonhormonal therapy)
Relative contraindications:
Age >60 years or >10 years since menopause onset
Spontaneous coronary artery dissection (SCAD)[10]
Advanced CKD with albuminuria
Non-Hormonal Medications
For women who cannot or prefer not to use hormone therapy, several options exist:
Antidepressants (SSRIs/SNRIs): Can reduce hot flashes and improve mood.
Gabapentin: Helps with hot flashes and sleep disturbances.
Vaginal moisturizers and lubricants: Relieve vaginal dryness and discomfort. They do not treat vasomotor symptoms.
Lifestyle Modifications Dr. Lodico Encourages All Women Should Optimize
Regular exercise: Exercise is the fouhtain of youth! Supports bone health, cardiovascular fitness, and mood.
Please lift weights regularly for longevity. Tell every women you know.
Balanced diet: Rich in calcium, vitamin D, and phytoestrogens.
Stress management: Techniques like yoga and mindfulness reduce anxiety and improve sleep.
Avoid triggers: Limiting caffeine, alcohol, and spicy foods can reduce hot flashes.
Complementary Therapies
Some women find relief with acupuncture, herbal supplements, or bioidentical hormones, though evidence varies. Always consult healthcare providers before starting supplements.
Choosing the Right Treatment
Selecting treatment depends on symptom severity, health history, personal preferences, and risk factors.
Women with severe hot flashes and no major health risks may benefit most from hormone therapy.
Those with mild symptoms or contraindications to hormones might try non-hormonal medications and lifestyle changes first.
Women concerned about bone health should discuss bone density testing and preventive strategies with their doctor.
