Perimenopause Explained: Symptoms, Hormones, and How to Feel Like Yourself Again
Perimenopause, often called the transition to menopause, is a natural stage that many women experience in their 40s—though it can begin earlier for some. It’s a time when hormones like estrogen, progesterone, and testosterone begin to shift, leading to changes that affect energy, mood, sleep, and overall health.
While it’s a normal part of life, perimenopause can feel confusing and overwhelming if you don’t know what to expect. The good news is that with the right knowledge and support, you can navigate this stage with confidence and protect your long-term health.
What is Perimenopause?
Perimenopause is the transitional phase before menopause, marked by fluctuating hormone levels and changes in the menstrual cycle. Menopause is officially reached after 12 months without a period, but perimenopause can last anywhere from 2–10 years.
During this time, hormones rise and fall unpredictably, which is why symptoms can feel inconsistent—one month may feel manageable, while the next can be disruptive.
Common Symptoms of Perimenopause
Every woman’s experience is unique, but some of the most common symptoms include:
Irregular or heavy periods
Hot flashes and night sweats
Mood swings, anxiety, or irritability
Trouble sleeping
Brain fog and memory issues
Slower metabolism and weight changes
Decreased libido and vaginal dryness
Hair thinning or skin changes
Not all women will have every symptom, but most notice a combination that can affect daily life and wellbeing.
The Role of Hormones: Progesterone and Testosterone
Hormonal shifts are at the core of perimenopause symptoms. While estrogen often gets the most attention, progesterone and testosterone also play vital roles in how women feel during this stage.
Progesterone: The Calming Hormone
Progesterone is typically the first hormone to decline in perimenopause.
Supports Sleep & Mood: It has a calming effect on the brain, so when levels fall, many women experience insomnia, anxiety, or restlessness.
Balances Estrogen: Low progesterone can lead to heavier or more irregular periods.
Bone & Breast Health: Healthy levels protect bone density and reduce breast sensitivity.
When progesterone drops, women often feel “wired but tired”—unable to relax even when exhausted. Bioidentical progesterone therapy can restore calm, improve sleep, and stabilize cycles.
Testosterone: The Forgotten Female Hormone
Though often associated with men, testosterone is essential for women’s health.
Energy & Motivation: It supports vitality, stamina, and drive.
Muscle & Metabolism: Helps maintain lean muscle and prevents midlife weight gain.
Sexual Health: Plays a direct role in libido, sensitivity, and sexual satisfaction.
Confidence & Mental Clarity: Supports focus, motivation, and emotional resilience.
When testosterone declines, women may notice fatigue, brain fog, and low desire. Restoring testosterone in balanced amounts helps bring back strength, energy, and confidence.
How to Support Your Body During Perimenopause
You don’t have to “just live with it.” The right lifestyle changes and professional support can ease the transition.

Sleep & Stress
Create consistent bedtime routines
Limit caffeine later in the day
Try meditation, journaling, or breathwork

Bioidentical Hormone Replacement Therapy (BHRT) to restore balance safely

Supplements like magnesium, omega-3s, adaptogens, and vitamin D to support resilience
