What if no one ever really explained to you what happens inside your body?<\/strong><\/h3><\/div>\n\n\n\n

You might feel like your body is playing tricks on you. Hot flashes that appear without warning, sleep that no longer does its job, fatigue that sets in for no apparent reason, roller-coaster emotions.<\/p>\n\n\n\n

You've probably been told that it's \u00abnormal,\u00bb that it's \u00abmenopause,\u00bb and that you should just endure it or take synthetic hormones and hope for the best.<\/p>\n\n\n\n

But what if the real problem was that no one had ever explained to you what's happening really<\/em> in your body?<\/p>\n\n\n\n

The truth is that menopause is not an illness. It is a natural transition, and your body has remarkable intelligence to navigate it. However, you must understand its language and give it the right tools.<\/p>\n\n\n\n

Thanks to the pioneering work of Dr. Jerilynn Prior, an endocrinologist at the University of British Columbia, and Dr. John Lee, a pioneer in natural progesterone, we now know that the key to this transition is not where conventional medicine is looking.<\/p>\n\n\n\n

And that's exactly what we're going to explore together.<\/p>\n\n\n\n

Your body is orchestrated by a duo: estrogen and progesterone<\/strong><\/h3><\/div>\n\n\n\n

Your hormonal system isn't a complicated mechanism reserved for medical textbooks. Instead, it's a dance, a constant dialogue between two hormones working in tandem to maintain the balance of your entire body.<\/p>\n\n\n\n

\"Female<\/figure><\/div>\n\n\n\n

On one hand, estrogen. It's the hormone of growth, abundance, and building. It stimulates tissues, thickens the uterine lining, keeps skin supple, and supports the brain and bones. In traditional Chinese medicine, it's associated with Yin, the nurturing, receptive energy that builds and accumulates.<\/p>\n\n\n\n

On the other hand, progesterone. It's the hormone of balance, calm, and regulation. It tempers the action of estrogen, protects the uterus, promotes sleep, and stabilizes mood. It's the Yang, the energy that contains, structures, and prevents Yin from overflowing.<\/p>\n\n\n\n

When these two hormones respond harmoniously to each other, everything runs smoothly. You sleep well, your energy is stable, your cycles are regular, and your mood follows your body's natural rhythm.<\/p>\n\n\n\n

But when progesterone fades, which is exactly what happens in perimenopause, estrogen is left without a counterbalance. The Yin overflows. And that's when symptoms appear.<\/p>\n\n\n\n

Dr. John Lee was one of the first physicians to understand and document this phenomenon. As early as the 1990s, he observed that the majority of women in perimenopause did not suffer from a lack of estrogen, but rather from a relative excess of estrogen compared to insufficient progesterone. He called this imbalance \u00abestrogen dominance.\u00bb A concept that changed how thousands of women understand their own bodies.<\/p>\n\n\n\n

Dr. Jerilynn Prior, with over 40 years of research in endocrinology, has confirmed these observations with solid clinical data: during perimenopause, estrogen levels do not drop. They may even rise 20 to 30% above normal levels. It is progesterone that disappears first. And it is this imbalance that triggers the cascade of symptoms so many women experience.<\/p>\n\n\n\n

In other words, the problem isn't that your body is lacking something. It's that it has lost its conductor.<\/p>\n\n\n\n

The menstrual cycle: a vital sign<\/strong><\/h3><\/div>\n\n\n\n

The menstrual cycle is often spoken of as if it only served one purpose: reproduction. But that's reductive. Your cycle is actually a vital sign, just like your temperature, pulse, or blood pressure. It reflects your overall health.<\/p>\n\n\n\n

A regular cycle with complete ovulation is a sign that your body is functioning well. That your adrenals are holding up, your thyroid is doing its job, your stress level is manageable, and your diet is nourishing your cells properly.<\/p>\n\n\n\n

Conversely, an irregular cycle, very heavy periods, intense premenstrual syndrome, or bleeding between cycles are all signs that something requires your attention. Your body isn't being capricious. It's communicating.<\/p>\n\n\n\n

And here's what most women don't know: you can get your period every month without actually ovulating<\/em>. Dr. Prior calls these \u00absilent ovulatory disorders.\u00bb On the surface, everything seems normal. Menstruation occurs. But behind the scenes, ovulation didn't happen, or it was incomplete. The result: inadequate progesterone production during the second half of the cycle.<\/p>\n\n\n\n

This is a phenomenon that is much more frequent than we believe, especially in women in their thirties and forties. Stress, lack of sleep, dietary restriction, excessive exercise, or simply the mental load of daily life can be enough to disrupt ovulation without us realizing it.<\/p>\n\n\n\n

And that's where the groundwork is laid. These years of insufficient progesterone, long before official menopause, quietly establish the imbalance. Yin begins to take over. The body accumulates the effects of an unopposed estrogen: tender breasts, water retention, irritability, increasingly erratic cycles.<\/p>\n\n\n\n

Understanding one's cycle is therefore much more than a question of fertility. It's learning to read your body's messages before they become cries.<\/p>\n\n\n\n

Perimenopause: The Grey Area No One Explains<\/strong><\/h3><\/div>\n\n\n\n

Perimenopause is this transition period that can start as early as the late thirties and last from 5 to 12 years before official menopause. And yet, almost no one talks about it clearly.<\/p>\n\n\n\n

Many women arrive at a healthcare professional's office with confusing symptoms: sudden hot flashes, insomnia, new anxiety, weight gain in the abdomen, and unpredictable periods. And too often, they are told it's \u00abstress,\u00bb that it's \u00abin their head,\u00bb or that they are \u00abtoo young for menopause.\u00bb.<\/p>\n\n\n\n

The problem is that the conventional model looks for an estrogen deficiency. They measure the hormones, see that the estrogen is still there, and conclude that everything is fine. Move along, ma'am.<\/p>\n\n\n\n

But Dr. Prior\u2019s research tells a very different story. During perimenopause, estrogen levels do not decline gradually. It goes on a roller coaster ride. Some days, it climbs to levels 20 to 30 % higher than in premenopause. Other days, it drops sharply. These unpredictable fluctuations are largely responsible for the symptoms women experience.<\/p>\n\n\n\n

And meanwhile, progesterone collapses. Ovulation becomes more and more irregular, sometimes absent. Without ovulation, no corpus luteum. Without a corpus luteum, no progesterone. The Yang disappears, and the Yin does what it wants.<\/p>\n\n\n\n

It's as if your internal thermostat is losing its reference point. Estrogen sends powerful, contradictory signals, and there's no one left to temper them.<\/p>\n\n\n\n

Dr. John Lee described perimenopause as the most misunderstood period in a woman's hormonal life. He insisted that the majority of symptoms attributed to menopause actually begin here, long before menstruation stops. And that the solution is not to add even more estrogen to a system that is already overflowing with it, but to restore what is missing: progesterone.<\/p>\n\n\n\n

This is a fundamental change in perspective. We are not trying to replace what is diminishing. We are trying to reestablish the balance between the two forces.<\/p>\n\n\n\n

Hot flashes demystified<\/strong><\/h3><\/div>\n\n\n\n

It is probably the most dreaded, most recognized, and most misunderstood symptom of the entire hormonal transition: the hot flash. That intense wave that rises without warning, that makes you blush in the middle of a meeting, that wakes you up drenched at three in the morning.<\/p>\n\n\n\n

What's going on really<\/em> in your body at that moment?<\/p>\n\n\n\n

Imagine your thermal regulation system as a thermostat with a comfort window. When everything is fine, this window is wide. Your body tolerates small temperature variations without reacting. It gets a little warmer? No problem. A little cooler? You adapt.<\/p>\n\n\n\n

During perimenopause, this window dramatically shrinks. Your thermostat becomes hypersensitive. The slightest rise in body temperature, even a tenth of a degree, triggers a disproportionate alarm signal. Your brain receives the message: \u00abEmergency! Overheating!\u00bb And it launches a massive cooling response. Blood vessels suddenly dilate, causing that intense heat sensation that rises to your face and chest. Sweating goes into overdrive. Your heart races.<\/p>\n\n\n\n

All this for a tenth of a degree.<\/p>\n\n\n\n

Dr. Prior has identified the mechanism behind this deregulation. In the hypothalamus, a region of the brain that controls temperature, there is a group of neurons called KNDy. These neurons are directly influenced by hormones. When estrogen fluctuates strongly and progesterone is absent to stabilize the system, these neurons become overactive. They send false overheating signals to the thermoregulation center.<\/p>\n\n\n\n

In other words, your hot flashes are not a whim of your body. It's a real neurological reaction, caused by a specific hormonal imbalance: too many estrogen fluctuations, not enough progesterone to calm things down.<\/p>\n\n\n\n

And that's excellent news. Because when you understand the cause, you can act on it. Dr. Prior's clinical studies have shown that progesterone supplementation significantly reduces hot flashes and night sweats precisely because it addresses the root of the problem rather than the symptom.<\/p>\n\n\n\n

Your body isn't broken. Its thermostat just needs to be reset to its happy place.<\/p>\n\n\n\n

Stress: The Hormonal Saboteur<\/strong><\/h3><\/div>\n\n\n\n

The impact of stress on hormonal balance is greatly underestimated. Not just major stress, like that from grief or major crises. Ordinary stress. The kind that silently accumulates, day after day. An argument with a colleague, a night of poor sleep, the mental load of organizing everything for everyone.<\/p>\n\n\n\n

The body doesn't differentiate between a real danger and an emotional overload. To your adrenal glands, the signal is the same: survival mode.<\/p>\n\n\n\n

Dr. Prior's research has documented that even stress considered \u00abminor\u00bb can be enough to disrupt ovulation. Why? Because producing progesterone is energetically expensive. When the body is under stress, it makes an instinctive choice: cortisol comes first, reproduction can wait. Ovulation is compromised, progesterone drops, and imbalance sets in.<\/p>\n\n\n\n

It's a formidable vicious cycle. Stress decreases progesterone. Lack of progesterone disrupts sleep and mood. Poor sleep increases stress. And the wheel keeps turning.<\/p>\n\n\n\n

Dr. Lee observed the same phenomenon in her practice. The women most affected by estrogen dominance were often those who carried the most responsibilities, those who \u00abheld everything together\u00bb without ever stopping. The body eventually sends the bill.<\/p>\n\n\n\n

This is why supporting your adrenal glands and stress resilience isn't a luxury. It's a fundamental pillar of hormonal balance.<\/p>\n\n\n\n

Support its balance naturally<\/strong><\/h3><\/div>\n\n\n\n

Natural Progesterone: Understanding Your Options<\/strong><\/p>\n\n\n\n

When you realize that progesterone is the missing piece, the next question naturally arises: how to support it? There are several avenues, from the gentlest to the most targeted. The important thing is to understand what each option offers to choose the one that suits your reality.<\/p>\n\n\n\n

Wild yam cream<\/strong><\/p>\n\n\n\n

This is the gentlest and most natural approach. Wild yam contains diosgenin, a plant compound whose structure resembles that of progesterone. Dr. John Lee was a great advocate of this route. For years, he documented the benefits of wild yam cream in his patients, observing improvement in symptoms of estrogen dominance, sleep, and bone density.<\/p>\n\n\n\n

Ferlow Cream<\/a> Botanicals is a benchmark in the field: formulated in Canada, without synthetic hormones, based on organic wild yam. It's an interesting option for women who want to support their hormonal balance gently and autonomously.<\/p>\n\n\n\n

Micronized progesterone cream<\/strong><\/p>\n\n\n\n

A little more targeted. This is a cream containing bioidentical progesterone, meaning a molecule identical to the one your body naturally produces. Transdermal application allows for gentle and gradual absorption through the skin. This option is particularly favored by women seeking more direct hormonal support while avoiding the oral route.<\/p>\n\n\n\n

Micronized progesterone capsules (Prometrium)<\/strong><\/p>\n\n\n\n

This is the most scientifically studied path. Dr. Prior's protocols recommend 200 to 300 mg of micronized progesterone taken at bedtime. The advantage of taking it at bedtime is twofold: it promotes sleep while maintaining stable hormone levels over 24 hours. Her clinical studies have demonstrated concrete effects on reducing hot flashes, bone protection, and cardiovascular health.<\/p>\n\n\n\n

Important point:<\/strong> Micronized progesterone has nothing to do with synthetic progestins like medroxyprogesterone, which carry very different risks. This is an essential distinction to understand. And this option requires a prescription as well as monitoring by a healthcare professional who is knowledgeable about bioidentical hormone therapy.<\/p>\n\n\n\n

Ground Support: Adaptogens and Iodine<\/strong><\/h3><\/div>\n\n\n\n

Restoring progesterone is essential. But if the body isn't ready to receive it, the results will be limited. It's like planting seeds in depleted soil. You have to nourish the earth first.<\/p>\n\n\n\n

Adaptogenic plants<\/strong><\/p>\n\n\n\n

Stress is one of the biggest saboteurs of hormonal production. Adaptogenic plants work exactly on that. They don't mask stress; they help your body respond to it better by supporting your adrenal glands and stabilizing cortisol.<\/p>\n\n\n\n

Ashwagandha calms the nervous system and improves sleep. Rhodiola supports endurance during periods of overwork. Eleuthero strengthens overall stress resistance. And reishi acts as a deep regulator of the immune and nervous systems. Together, these plants bring the body back to its equilibrium point rather than forcing it in one direction.<\/p>\n\n\n\n

Iodine: The Great Overlooked Element for Hormonal Balance<\/strong><\/p>\n\n\n\n

Dr. David Brownstein considers iodine an essential element for female hormonal balance. Iodine helps the body metabolize estrogen into less active forms, reducing the effects of estrogen dominance. It also supports the thyroid, a gland intimately linked to overall hormonal balance. An underactive thyroid can amplify all menopausal symptoms: fatigue, weight gain, feeling cold, and brain fog.<\/p>\n\n\n\n

The Lugol 2 %<\/a> Offers a bioavailable form combining iodine and potassium iodide, both forms the body uses. A simple supplement that can make a remarkable difference in a holistic approach.<\/p>\n\n\n\n

Going further: understanding to act better<\/strong><\/h3><\/div>\n\n\n\n

Menopause is not a disease to be fought. It is a transition to be managed with intelligence, gentleness, and the right tools. And the first tool is understanding.<\/p>\n\n\n\n
