Perimenopause
Perimenopause is a neurological and metabolic transition that amplifies whatever was already out of balance. We steady blood sugar, sleep, the brain, and hormone signaling in sequence.
What you may be noticing
Your cycles shorten, lengthen, or flood. Sleep breaks at 3am. Anxiety arrives out of nowhere, along with rage, tears, or flatness. Your brain feels foggy, weight shifts to your middle, your joints ache, and intimacy may feel different. You may be told you are too young for menopause and that your labs are normal. Yet you know something has changed.
Why it is rarely one thing
Perimenopause is not simply estrogen running out. In the early years, estrogen often swings widely, sometimes higher than before, while progesterone declines first. Those swings shift serotonin, dopamine, and GABA signaling, thyroid sensitivity, insulin signaling, and cortisol rhythm.
In my experience, the transition amplifies what was already present: unstable blood sugar, short sleep, a high stress load, or sluggish thyroid activation. That is good news, because each of those can be supported.
Hormones also follow instructions from the brain. The hypothalamus and pituitary direct the ovaries, adrenals, and thyroid, and the hypothalamus regulates temperature. Regulating the nervous system is part of regulating hormones. Hot flashes are not something you fight. They are something you regulate.
Common is not normal. These symptoms are frequent, and they deserve real attention. How you move through this window also shapes long-term brain, bone, heart, and metabolic health. It is a transition, not a collapse.
Patterns we look for
- Progesterone decline and relative estrogen dominance.
- Estrogen metabolism and clearance through the liver and gut.
- Insulin resistance, which rises as estrogen fluctuates.
- HPA axis output and cortisol rhythm.
- Thyroid activation, since thyroid changes often surface in midlife.
- Sleep architecture and night-time blood sugar.
- Neurotransmitter balance: serotonin, GABA, and dopamine.
- Iron status, especially with heavy bleeding.
- Bone and muscle health.
- Pelvic floor, vaginal tissue, and intimate health, which share the same hormonal and nervous system roots.
- The gut microbiome and estrobolome.
How I evaluate it
A comprehensive functional neurological exam assesses autonomic balance, thermoregulation, cognitive stamina, and the brain regions affected by hormonal change.
Functional labs may include cycle-timed hormones or a hormone metabolite panel, a full thyroid panel, iron and ferritin, fasting insulin and HbA1c, a lipid panel, vitamin D, inflammatory markers, and cortisol rhythm. Hormone therapy decisions are made with your prescribing physician, and I support whichever path you choose.
Very heavy bleeding, bleeding after sex, or bleeding after a year without periods needs gynecologic evaluation.
How we address it
- Stabilize blood sugar with protein-forward meals, and build muscle with strength training.
- Restore sleep and regulate the nervous system, the command center for hormonal signaling.
- Support liver and gut clearance of hormones, so estrogen is metabolized well and receptors respond clearly.
- Support progesterone balance and healthy estrogen metabolism, alongside any hormone therapy chosen with your physician.
- Address thyroid activation, iron, cortisol rhythm, and bone health.
- Use brain-based exercises and breath practices to steady thermoregulation and mood.
This is not an ending. It is a recalibration, and you can move through it with clarity and strength.
