Understanding the Hidden Impact of Perimenopause on Midlife Health

Over the past year, I've found myself having more conversations about women's health than ever before not only with healthcare professionals, but with friends, colleagues, and women I meet in everyday life. What has struck me most is how often those conversations sound very similar.

Women describe anxiety that seems to appear out of nowhere. They talk about disrupted sleep, brain fog, fatigue, mood changes, heart palpitations, rising cholesterol, elevated blood pressure, and a growing sense that something simply feels different. Many have sought answers from multiple providers. Some have undergone extensive testing. Yet few were ever told that hormones might be part of the conversation.

As someone currently navigating this stage of life myself, I was eager to sit down with Dr. Jackie Vannuyen, a board-certified OB-GYN and menopause-certified provider, to better understand why so many women feel blindsided by midlife changes and why so many continue to struggle in silence.

One of the first things Dr. Vannuyen emphasized was that perimenopause is far more than a reproductive transition.

"We have hormone receptors all over our body regulating every single process from our mental health to our physical health to our metabolism to our microbiome to our immunity." She explained that as hormone levels begin to fluctuate because of declining egg count and egg quality, "it affects our entire system."

That perspective helps explain why so many women experience symptoms that seem unrelated on the surface. While hot flashes and irregular periods often dominate the conversation, many women first notice changes in mood, sleep, cognition, cardiovascular health, and overall well-being.

As our conversation continued, I asked Dr. Vannuyen what led her to focus so much of her work on perimenopause and menopause care. Like many OB-GYNs, her training focused heavily on obstetrics, surgery, cancer screening, and reproductive health. What received far less attention was the period of life that follows.

"There is a gender gap about this period of life for women when it doesn't involve our fertility."

What resonated most with me was her honesty about her own professional journey. Reflecting on years of caring for women, she shared: "I would document all their symptoms. But I did not know how to take them to the next step. I did not know how to help them. I could not connect the dots."

That realization then became personal.

"And I'm 52. I'm perimenopausal. And as it started happening to me, I was like, no, I'm not going to suffer like this.” It was that experience, combined with what she was seeing in her patients, that prompted her to seek additional education and certification in menopause care.

"My patients are suffering, too. There's more. So I had to get more training. I had to get more education to become a menopause-certified provider, to provide this care for women because there's such a huge gap."

Throughout the interview, one theme surfaced repeatedly: many women simply do not feel like themselves. Whether it is anxiety, brain fog, low motivation, sleep disruption, or emotional changes, the symptoms can feel confusing and disconnected. Dr. Vannuyen explained that there are biological reasons behind many of these experiences. "Because of fluctuating and declining estrogen, our serotonin drops. That's our happy hormone. So there's where that anxiety and depression starts to increase."

She also noted that dopamine levels can be affected, contributing to cognitive symptoms and brain fog, while poor sleep creates an additional layer of challenges that impacts everything from mood to cardiovascular health.

One of the most powerful moments in our discussion came when we began talking about why so many women continue to suffer without answers. Dr. Vannuyen was candid about the fact that, prior to her additional menopause training, she sometimes attributed symptoms to stress and life circumstances because she did not have the education necessary to recognize the hormonal connection. Today, she hears similar stories from women who have spent years searching for answers.

According to Dr. Vannuyen, studies show that women often see multiple healthcare providers before receiving a diagnosis of perimenopause. When I asked why these struggles have remained so invisible, her answer was immediate.

"I think it remains invisible because we normalize women's suffering."

She went on to describe the many responsibilities women often carry during midlife. "Women carry the mental load of a lot of things, family, careers, those kinds of things. You're in this sandwich generation, like you said, caring for parents, caring for children still. And we are supposed to be super women. We're supposed to do it all."

Another significant theme of our discussion centered on the way healthcare often treats symptoms individually rather than collectively. Many women find themselves navigating separate diagnoses such as anxiety, hypertension, elevated cholesterol, sleep disturbances, and fatigue. Yet the connection between these concerns and hormonal changes is not always explored.

Dr. Vannuyen believes part of the challenge lies in fragmented care. "The treatment is fragmented and, you know, you see your cardiologist, you see your mental health professional, your gynecologist is not helping you. So that is also like the huge gap that needs to be fixed.” Rather than a siloed approach, she envisions a more integrated model of care that addresses hormonal health alongside nutrition, mental health, cardiovascular health, bone health, pelvic health, and metabolic health.

The conversation also touched on the importance of partners, families, and communities understanding what women experience during this stage of life. "When it affects women, it not only affects women, it affects their families, how they show up with their kids and their husbands and their partners.” For Dr. Vannuyen, education is not just for women. It is for everyone whose life intersects with the women they care about.

As our conversation came to a close, I asked what she would want women who feel exhausted, dismissed, or disconnected from themselves to know. Her answer was simple and powerful.

"Not alone. Billions of women are entering this space and so let's talk about it. Let's support each other, you know, in whatever ways that we can with education, with help, with support because we don't have to do this alone."

For many women, the conversation around perimenopause is arriving later than it should have. But perhaps the most important takeaway from my discussion with Dr. Vannuyen is that awareness is growing, education is expanding, and women are beginning to realize that the symptoms they have been experiencing are not isolated, imagined, or theirs alone to carry.

The more we talk about perimenopause, the more we create space for women to be informed, supported, and understood during a transition that affects far more than hormones alone.
