Perimenopause and Menopause 

Understanding Hormonal Changes and How to Manage Them 

At some point in their late 30s to mid-40s, most women begin noticing subtle changes in their menstrual cycles or how they feel throughout the month. Periods that were once predictable may become irregular, and new symptoms, such as mood swings, sleep issues, or night sweats, can begin to surface. 

This transitional time, known as perimenopause, marks the gradual shift toward menopause, when the ovaries slow and eventually stop producing hormones like estrogen, progesterone, and testosterone. Once a woman has gone 12 consecutive months without a menstrual period, she is considered to be in menopause. 

Perimenopause and menopause are both natural, universal stages of life, but the hormonal changes they bring can cause a variety of physical and emotional symptoms. At The Woman’s Health Pavilion, our experienced providers are here to help you understand these changes, relieve your symptoms, and protect your long-term health. 

What Is Perimenopause? 

The Transition Before Menopause 

Perimenopause typically begins in a woman’s 40s, but it can start as early as the mid-30s. This stage can last several years, sometimes up to 10, before menstruation stops completely. During perimenopause, hormone levels fluctuate unpredictably, causing both physical and emotional changes that for some can be very disruptive.  

Common Signs and Symptoms 

• Irregular or unpredictable menstrual cycles 

• Heavier or lighter bleeding than usual 

• Hot flashes or night sweats 

• Mood swings, irritability, or anxiety 

• Difficulty sleeping or staying asleep 

• Brain fog or difficulty concentrating 

• Fatigue or low energy 

• Decreased libido 

• Breast tenderness or bloating 

Some women describe feeling like they “just don’t feel like themselves.” Others experience mood changes that resemble severe PMS, sometimes accompanied by irritability or even anger. These symptoms can fluctuate in intensity, mild one month and horrible the next, which can add to the frustration. 

Why These Changes Occur 

During perimenopause, the ovaries begin producing hormones in an irregular pattern. Estrogen may spike high one month and dip low the next, while progesterone production gradually declines. This hormonal volatility can affect the brain, skin, metabolism, and even emotional regulation—explaining the wide variety of symptoms women experience. 

Diagnosis 

Perimenopause is typically diagnosed based on your age, menstrual history, and symptoms. Blood tests may be ordered to rule out other causes of irregular periods or fatigue—such as thyroid disorders or anemia—but hormone levels often appear “normal” even when symptoms are significant. Your provider at The Woman’s Health Pavilion will evaluate your full clinical picture to determine whether you’re in this transitional stage. 

What Is Menopause? 

The End of the Reproductive Years 

Menopause officially begins when a woman has gone 12 consecutive months without a menstrual period. The average age of menopause is 51, though it can occur earlier or later. Menopause before age 45 is considered early, and before 40 is considered premature. Family history plays a strong role—women tend to experience menopause around the same age as their mothers or sisters. 

Menopause marks the end of ovarian hormone production. While it is a normal part of aging, the loss of estrogen can have widespread effects on the body—impacting temperature regulation, sleep, bone health, skin elasticity, and even cardiovascular function. 

Common Symptoms Around and After Menopause 

• Persistent hot flashes and night sweats 

• Sleep disturbances or insomnia 

• Mood changes or depression 

• Vaginal dryness and discomfort with intercourse 

• Decreased libido 

• Joint pain or stiffness 

• Memory lapses or “brain fog” 

Remember that symptoms vary widely; some women notice little change, while others experience symptoms that interfere with daily life.  

For most, once menopause is diagnosed, symptoms improve within a few years. However, for some, these symptoms may persist longer. The figure below shows how many years hot flashes lasted in 501 women after they reached menopause (i.e., the timeline begins when their period had already stopped). 

Diagnosing Menopause 

Women frequently ask if we can do a “blood test” to check for menopause. For women presenting with “typical” symptoms at a “typical” age, blood testing is not particularly useful: Women around 50 with their periods fizzling out and complaints of hot flashes are clearly going through menopause, and we don’t usually require a blood test to make that diagnosis. At the extremes of age, or if there’s something unusual about the process, we can check certain labs to get an idea about your level of ovarian function. 

How Menopause Affects Long-Term Health 

Heart Health 

Estrogen helps protect the cardiovascular system by maintaining healthy cholesterol levels and promoting blood vessel flexibility. After menopause, LDL (“bad”) cholesterol often rises while HDL (“good”) cholesterol decreases, raising the risk of heart disease.  It is well-known that the risk of heart disease increases with age. As the accompanying graph shows, menopause confers additional risk of cardiovascular disease: In each age group, the risk of cardiovascular disease is significantly higher among women who are already menopausal. In fact, a woman who is menopausal at the age of 42 has about the same risk of heart disease as a pre-menopausal woman at age 52. 

Bone Health 

Bone loss accelerates rapidly after menopause due to the decline in estrogen levels, which increases the risk of osteopenia and osteoporosis. One in six women over age 50 will experience a hip fracture, which can significantly impact independence. Bone density testing, calcium and vitamin D intake, weight-bearing exercise, and certain hormone replacement therapies can all help maintain bone strength. 

Managing Perimenopause and Menopause 

Personalized Care Is Essential  

Every woman’s experience is unique, which is why treatment at The Woman’s Health Pavilion is always individualized. Whether your symptoms are mild or severe, we can create a plan to support your comfort, hormone balance, and long-term well-being. 

1. Lifestyle and Preventive Care 

Small, consistent changes can make a big difference in managing symptoms and protecting your health: 

• Engage in regular physical activity, including strength training and cardiovascular exercise. 

• Eat a balanced diet rich in fruits, vegetables, lean proteins, calcium, and healthy fats. 

• Limit alcohol, caffeine, and processed foods, which can worsen hot flashes and sleep problems. 

• Practice good sleep hygiene and stress management through yoga, meditation, or mindfulness. 

• Stay up to date with preventive screenings such as mammograms, Pap tests, colonoscopy, and bone density scans. 

2. Non-Hormonal Treatment Options 

For women who prefer not to use hormones or cannot take them due to medical reasons, there are several safe and effective alternatives: 

• Certain antidepressants (SSRIs) and medications like Veozah can help reduce hot flashes and mood changes. 

• Vaginal moisturizers and lubricants relieve dryness and discomfort. 

• Prescription non-hormonal therapies can target specific symptoms like sleep disturbances or night sweats. 

• Certain supplements, like Black Cohosh, have been shown to modestly improve menopause-related symptoms such as hot flashes.  

3. Hormone Therapy (HRT) 

Hormone Replacement Therapy (HRT) remains the most effective treatment for hot flashes, night sweats, and other perimenopause and menopause-related symptoms. HRT can also help protect bone density, improve mood and sleep, and may reduce the risk of heart disease when started before the onset of menopause. 

HRT can be given as estrogen, progesterone, or testosterone—or a combination of these hormones. Which hormones you need will depend on multiple factors including your symptoms, your preferences, and whether you have a uterus or not.   

HRT can be customized in several forms—oral tablets, skin patches, creams, gels, or pellets—depending on your needs, preferences, and health status.  

For women in perimenopause, low-dose hormonal birth control may be the best treatment regimen, as it can regulate cycles, reduce bleeding, and provide symptom relief while still offering contraception. 

For those experiencing vaginal dryness or pain, local vaginal estrogen or DHEA therapy deliver targeted relief with minimal systemic absorption. These treatments also help lower the risk of recurrent urinary tract infections. 

The Bottom Line 

Perimenopause and menopause are natural milestones—but that doesn’t mean you have to suffer through them. With expert care, personalized treatment, and the right lifestyle support, you can move through this transition feeling balanced, healthy, and empowered.
