What Is Perimenopause?
Perimenopause literally means "around menopause." It typically begins in a woman's early-to-mid 40s (though it can start in the late 30s) and lasts anywhere from 2 to 10 years, ending 12 months after the final menstrual period.
During this time, estrogen and progesterone levels fluctuate erratically — not simply declining, but swinging unpredictably. This hormonal volatility is what drives most perimenopausal symptoms. Because cycles can remain irregular rather than stopping, many women and even some clinicians do not recognize the transition for what it is.
Common Symptoms
- Irregular periods — shorter cycles, skipped cycles, or heavier bleeding
- Sleep disruption and insomnia, often without obvious hot flashes
- Mood changes: anxiety, irritability, depression, or emotional volatility
- Brain fog and memory lapses
- Hot flashes and night sweats (may be milder than full menopause)
- Low libido and vaginal dryness
- Weight changes, especially abdominal weight gain
- Joint pain and fatigue
- Heart palpitations
How Dr. Mary Approaches Perimenopause
Hormonal Evaluation
Because perimenopausal hormone levels fluctuate so widely, standard single-point blood tests can be misleading. Dr. Mary often uses a combination of blood and salivary hormone testing — looking at estradiol, progesterone, testosterone, DHEA-S, cortisol, and FSH — to build a picture of what is actually happening hormonally.
Bioidentical Hormone Support
When symptoms are significantly impacting quality of life, low-dose bioidentical progesterone is often the first hormonal intervention — it is frequently the most deficient hormone early in the perimenopausal transition and has a strong safety profile. Estrogen and testosterone support are added when indicated by labs and symptoms.
Nervous System & Sleep Support
Perimenopausal sleep disruption is driven by both hormonal and nervous system changes. Dr. Mary addresses this with targeted sleep hygiene, magnesium, adaptogens (ashwagandha, rhodiola), and when needed, botanical support for cortisol regulation.
Nutrition & Metabolic Health
The perimenopausal years are a critical window for metabolic health. Insulin sensitivity shifts, and abdominal fat accumulation can increase cardiovascular and metabolic risk. A protein-forward, lower-glycemic diet with regular resistance exercise is a cornerstone of the plan.
Cycle Charting & Tracking
Understanding your own cycle patterns during perimenopause is empowering. Dr. Mary often teaches symptom and cycle tracking as a diagnostic and monitoring tool.
