The gap nobody is talking about

[0:01:06]

Alex opens the episode with a striking observation from a women’s health conference he attended: when a room full of women was asked how many of them knew what perimenopause was, only about a third raised their hands. Dr. Westgate is not surprised. Perimenopause, she explains, is a phase of life that arrives with more than 35 identified symptoms, can begin years before any change in a woman’s menstrual cycle, and is so poorly understood that many physicians cannot adequately prepare their patients for it. The gap is not just cultural. It is clinical.

“It’s a phase of life that comes along with a lot of very confusing symptoms that a lot of physicians don’t even understand, and so are unable to guide their patients and really prepare them for what’s coming.”

Three hormonal transitions versus one: why women’s biology is fundamentally different

[0:03:25]

Dr. Westgate puts the female hormonal lifespan into context in a way that reframes everything. Women go through three major hormonal transitions: puberty, each pregnancy, and then the perimenopause and menopause shift. Men go through one. And unlike men, whose hormone levels remain relatively stable across their adult lives, women are already accustomed to monthly hormonal fluctuation from their menstrual cycle. When those fluctuations begin to change because of an aging ovary, the symptoms that emerge are not random. They are the predictable consequence of a system being pushed beyond its normal range.

When does perimenopause actually begin?

[0:01:48]

Menopause, on average, occurs at around age 53. Normal is anywhere between 45 and 55. Perimenopause, by definition, occurs five to ten years before a woman’s last menstrual period. Which means that for a woman biologically scheduled to reach menopause at 45, perimenopause may be underway in her late 30s, before her period has changed at all.

The textbook sign that perimenopause has begun is a change in menstrual cycle length: periods arriving closer together, spacing out, or becoming irregular. But Dr. Westgate is clear that for many women, significant symptoms arrive before that cycle changes, which is where the confusion and the misdiagnosis begins.

The three earliest symptoms: sleep, mood, and weight

[0:04:49]

Before a woman’s period changes, the three symptoms Dr. Westgate sees most consistently in her clinic are disrupted sleep, mood dysregulation, and shifts in weight. Layered over all three is a feeling that is harder to name but just as real: I do not feel like myself. Something is changing and I cannot put my finger on what it is.

On sleep specifically, the signature pattern is a 2 to 3am awakening with no obvious cause, followed by difficulty returning to sleep, rumination, and anxiety. Critically, this happens even in women who are not yet experiencing hot flashes. The sleep disruption is hormonal, not thermal, which means women who have been told to wait for hot flashes before investigating further may already be losing sleep for years.

“Even without the quintessential menopause symptom of hot flashes, women report sleep issues during these hormonal changes and shifts.”

Hormonal chaos versus hormonal flatline: perimenopause versus menopause

[0:08:15]

Dr. Westgate draws a distinction that reframes the entire conversation. Menopause is a state of hormonal flatline: no estrogen, no progesterone, low and stable. Perimenopause is something entirely different. It is hormonal chaos. The brain, sensing low estrogen, begins signaling the ovaries as loudly as it can. Sometimes two eggs mature simultaneously, producing a surge of estrogen. Then hormones crash. Then the cycle repeats, unpredictably.

The result is that a perimenopausal woman is not experiencing consistently low hormones. She is swinging from high highs to low lows, sometimes within the same cycle. This is why the mood symptoms of perimenopause can actually be more severe than those of menopause itself, and why the experience of feeling like permanent PMS is, hormonally speaking, an accurate description of what is happening.

“The etiology of perimenopause is hormonal chaos. High highs to low lows and everything in between.”
— Dr. Candace Westgate

The misdiagnosis epidemic

[0:10:19]

One of the most striking moments in the episode is a clinical story Dr. Westgate shares without embellishment. A patient came to her clinic recently and told her: you are the eighth specialist I have seen. Can you please explain to me what is going on inside my body?

The problem, Dr. Westgate explains, is structural. The US healthcare system excels at specialization. A woman experiencing joint pain, heart palpitations, urinary urgency, and mood changes will be sent to a rheumatologist, a cardiologist, a urologist, and a psychiatrist. Each specialist looks at their organ system in isolation. Without someone to quarterback the whole picture and recognize hormonal dysregulation as the underlying cause, a woman can accumulate five or six new medications in six months and still have no diagnosis.

When the hormonal root cause is identified and addressed, Dr. Westgate notes that medical management often simplifies substantially while arriving at the same or better outcomes.

Your pregnancy history as a fortune teller

[0:15:21]

One of Dr. Westgate’s most compelling clinical frameworks is using a woman’s reproductive history as a predictor of her perimenopausal experience. Before a consultation even begins, she asks her patients: what was your pregnancy like? Did you love it or hate it? How was your postpartum experience? Did you struggle with depression or mood changes? Did you have high blood pressure during pregnancy, gestational diabetes, or pre-eclampsia?

The logic is direct. Pregnancy and postpartum are periods of significant hormonal stress. The way a woman’s body responded to that stress is a preview of what she may be at risk for during perimenopause. A history of postpartum depression predicts a higher likelihood of significant mood symptoms. A history of gestational diabetes or pre-eclampsia flags cardiovascular and metabolic risk that needs monitoring ahead of the transition. Her body has already told the story once. The task is to read it.

“What happens in pregnancy and postpartum is fortune telling for us in regards to what we need to look out for in this next hormonal transition.”
— Dr. Candace Westgate

Your menstrual cycle is a vital sign

[0:17:00]

As an OB-GYN, Dr. Westgate treats the menstrual cycle as a vital sign in the same way a physician treats blood pressure or heart rate. It is a monthly readout of what is happening hormonally, and changes in it carry clinical information that most women and most physicians are not being trained to read.

She encourages every patient to pay attention month by month. How is the cycle changing? What does this month look like relative to last month? And what is the context: how is sleep, stress, and nutrition aligning with those changes? Even basic education about the two phases of the menstrual cycle, the follicular phase and the luteal phase, and which hormones are dominant in each, can give a woman a meaningful framework for understanding her own body before perimenopause arrives.

Sleep is a superpower and most women do not know they are losing it

[0:20:03]

Dr. Westgate makes one of the episode’s strongest arguments around sleep. It is not just about duration. It is about quality, and the two are not the same thing. She uses her own experience as an example. She was getting seven to eight hours a night. She had no obvious sleep complaints. She would have told anyone she was fine. When she started measuring her sleep with a wearable device, she discovered that while the quantity was adequate, her quality was poor. She was not getting enough REM and deep sleep to receive the health benefits she believed she was getting, including immune function, cancer prevention, disease prevention, and cognitive restoration.

The downstream consequences of poor sleep quality are significant and often invisible. A single night of disrupted sleep leads to consuming 200 to 300 extra calories the following day, with a strong preference for fast food, simple carbohydrates, and sugar. This is not a willpower problem. It is a physiology problem, and for perimenopausal women, sleep is typically one of the first things to deteriorate.

“You cannot optimize what you cannot measure. I thought I was doing fantastic. When I measured, I realized that though I was getting the right quantity of sleep, my quality was terrible.”

Dr. Westgate’s personal story

[0:21:55]

Dr. Westgate shares that turning 40 was, for her, a moment of reckoning. A previous cancer diagnosis and a family history riddled with cancer pushed her to ask a question that healthcare rarely encourages: what do I want the next ten, twenty, thirty years to look like? After years focused on reproduction, on her patients’ fertility and on her own, she turned her attention to what came next.

What she found was that the research on midlife women’s health is thin, that training for primary care and OB-GYN physicians in this area is inadequate, and that the personal experience of navigating it was the most powerful teacher available. Her journey into cancer prevention led her, unexpectedly, into perimenopause and menopause knowledge because, as she puts it, everything in the human body is so intertwined. That integration is the core of her clinical philosophy and of this episode.
