    Feeling Everything All at Once? | Ep. 79 — I AM YOU

    I AM YOU is hosted by Nitza I. Alvarez, MD, FACC—a board-certified cardiologist, Women’s Heart Specialist, and bestselling author. Each episode shares real stories and expert insights that help women understand their unique heart health, manage stress, and take charge of their well-being. Dr. Alvarez’s mission is simple: to inspire every woman to become the CEO of her own health—with knowledge, confidence, and community. In this episode, Dr. Alvarez explains why so many women in their 40s suddenly feel as though everything in their bodies is changing at once. Anxiety, disrupted sleep, brain fog, heart palpitations, weight gain, and difficulty concentrating may appear unrelated—but they can all be part of the same system-wide transition. Perimenopause is not simply one symptom or a reproductive change. Estrogen acts as a messenger throughout the body, communicating with the brain, nervous system, metabolism, immune system, blood vessels, and cardiovascular system. When estrogen begins fluctuating unpredictably, the body loses its stable signal—and multiple symptoms can emerge simultaneously. Dr. Alvarez explains how declining hormonal protection can contribute to increased inflammation, blood pressure, cholesterol, insulin levels, and changes in the way the body stores fat. What feels like your body “falling apart” may actually be your body signaling that an important physiological transition is taking place. With clarity and compassion, Dr. Alvarez explains: Why perimenopause can cause multiple symptoms at the same timeHow estrogen affects the brain, metabolism, nervous system, and blood vesselsWhy palpitations, anxiety, brain fog, and sleep problems may be connectedWhy normal laboratory results do not always tell the full storyWhich cardiovascular and metabolic evaluations women should considerWhy recognizing these changes early is essential for preventionYour body is not failing, and what you are experiencing is not random or “all in your head.” These symptoms may be early signals of physiological changes that can affect your cardiovascular health over the next five to ten years. You do not have to wait for something to go wrong before taking your health seriously. Listen to your body, recognize the pattern, seek a proper evaluation, and become the CEO of your own health. Listen in, share this episode with the women in your life, and join the movement to change how women experience heart health. Visit NitzaMD.com Follow @NitzaMD on Instagram and Facebook.

    It’s Hormones, Not Your Marriage - Ep 78 - I AM YOU

    I AM YOU is hosted by Nitza I. Alvarez, MD, FACC — board-certified cardiologist, Women’s Heart Specialist, and bestselling author. Each episode shares real stories and expert insights to help women protect the heart that carries them through every stage of life—and become the CEO of their own health. In this deeply personal episode, Dr. Alvarez explores a question many women may never think to ask: What if the thing creating tension in your marriage is not your relationship—but the hormonal changes happening inside your body? For nearly two years, Dr. Alvarez did not feel like herself. She experienced irritability, frustration, a loss of intimacy, and growing resentment toward her husband. Small things felt overwhelming, conversations became arguments, and she began questioning whether she wanted to remain in the marriage. Then, while attending a medical conference, she heard experts describe the mood changes, loss of desire, relationship conflict, and emotional instability that can occur during perimenopause—and realized they were describing her. Dr. Alvarez explains that estrogen is not simply a reproductive hormone. It also affects the brain, blood vessels, inflammation, mood, mental clarity, energy, and cardiovascular health. During perimenopause, estrogen levels may fluctuate unpredictably, changing how women think, feel, react, and perceive the people closest to them. In this episode, Dr. Alvarez explains: How fluctuating estrogen can affect mood, patience, and emotional reactionsWhy small frustrations may suddenly feel intolerableHow hormonal changes can contribute to relationship conflictWhy declining estrogen and testosterone can reduce libidoHow inflammation affects both the brain and the cardiovascular systemWhy therapy may be valuable—but should sometimes be accompanied by a hormonal evaluationWhy low libido should not automatically be dismissed as normal agingHow changes in mood and relationships may signal broader hormonal, metabolic, and cardiovascular changesDr. Alvarez makes it clear that hormones do not excuse unhealthy behavior, and women should never remain in an abusive or unsafe relationship. However, when a previously loving relationship suddenly feels different, it may be important to evaluate what is happening physiologically before making a permanent decision. The same hormonal changes affecting mood, energy, perception, and intimacy may also be affecting cholesterol, inflammation, blood vessels, and heart health. What feels like a relationship problem may also be the body signaling that something deeper is changing. This episode encourages women to pause, listen to their bodies, and investigate what may be driving their symptoms—not simply accept that this is “who they are now.” Before deciding that your relationship has changed, ask whether your body has changed. Listen in, share this episode with the women you love, and take another step toward becoming the CEO of your own health. Visit NitzaMD.com Follow @NitzaMD on Instagram and Facebook.

    The Truth About Hormone Therapy — Ep. 77 — I AM YOU

    I AM YOU is hosted by Dr. Nitza I. Alvarez, MD, FACC — board-certified cardiologist, Women’s Heart Specialist, and bestselling author. Each episode shares real stories and expert insights to help women protect the heart that carries them through every stage of life — and step into their power as the CEO of their own health. In this episode, Dr. Alvarez confronts one of the most persistent fears surrounding menopause care: the belief that hormone therapy automatically causes breast cancer. Many women experiencing sleeplessness, anxiety, weight gain, hot flashes, and other symptoms of hormonal transition are told to avoid estrogen and simply “push through” menopause. But reducing the hormone therapy conversation to breast cancer alone ignores the broader effects of declining estrogen on the brain, blood vessels, metabolism, inflammation, and cardiovascular system. Dr. Alvarez explains how early interpretations of the Women’s Health Initiative created decades of fear and confusion—even though the women studied were, on average, over age 60 and more than 10 years past menopause. She discusses why the timing, type, and method of hormone therapy matter, and why treatment should never be approached as a universal yes-or-no decision. With clarity and urgency, she breaks down: Why estrogen is more than a reproductive hormone—and how it helps regulate the brain, blood vessels, metabolism, and immune systemHow the timing of hormone therapy affects its risks and potential benefitsThe difference between estrogen-only therapy and combined estrogen-progestin therapyWhy the breast cancer risk associated with combined therapy is often misunderstood or overstatedThe important difference between a family history and a personal history of breast cancerWhy systemic hormone therapy is generally avoided in breast cancer survivors, but may require individualized discussion in severe casesWhen low-dose vaginal estrogen may still be considered with shared decision-making and oncology involvementHow declining estrogen can contribute to arterial stiffness, inflammation, insulin resistance, changing cholesterol levels, and cardiovascular diseaseWhy avoiding hormone therapy is not automatically the safest choiceHow women can evaluate their personal, metabolic, cardiovascular, and breast cancer risks more accuratelyThis episode challenges women to stop making healthcare decisions based solely on fear. Hormone therapy is not appropriate for every woman, but the decision must be based on personal history, cardiovascular risk, metabolic health, symptoms, timing, and the specific treatment being considered. Hormone therapy is not the enemy. Misunderstanding it is. Your symptoms are not random—they are signals of physiological change. Becoming the CEO of your own health means listening to those signals, asking informed questions, and seeking individualized care before silent changes develop into disease.

    Why Menopause Changes Your Heart - Ep 76 - I AM YOU

    I AM YOU is hosted by Nitza I. Alvarez, MD, FACC — board-certified cardiologist, Women’s Heart Specialist, and bestselling author. Each episode shares real stories and expert insights to help women protect the heart that carries them through every stage of life and step confidently into their role as the CEO of their own health. In this episode, Dr. Alvarez addresses a question many women begin asking in their 40s: Why am I suddenly exhausted, anxious, gaining weight, struggling with brain fog, and experiencing a racing heart when I am doing everything right? Too often, women are told that these changes are simply stress, anxiety, aging, or “just menopause.” But what appears to be hormonal on the surface may also reflect significant changes taking place within the cardiovascular system. Through the story of a healthy, active 46-year-old woman who no longer felt like herself, Dr. Alvarez explains how fluctuating and declining estrogen can affect the blood vessels, metabolism, inflammation, cholesterol, insulin sensitivity, heart rhythm, and long-term risk of heart disease. Estrogen is not only a reproductive hormone. It also plays an important role in keeping blood vessels flexible, regulating inflammation, supporting healthy blood flow, balancing cholesterol, and helping the body respond to insulin. During perimenopause, estrogen can become unpredictable before eventually declining, placing stress on multiple systems at once. With clarity and compassion, Dr. Alvarez explains: Why fatigue, anxiety, brain fog, palpitations, irritability, low libido, and abdominal weight gain are not necessarily random symptomsHow perimenopause and menopause affect blood vessels, metabolism, inflammation, and heart rhythmWhy women may gain weight despite eating well and exercising consistentlyHow cardiovascular risk can begin accelerating during the menopause transitionWhy “normal” test results do not mean that nothing is changingWhich numbers women should monitor, including blood pressure, cholesterol, glucose, and insulinWhy symptoms should be treated as valuable health data rather than dismissed as an inconvenienceHow awareness and early prevention can protect the heart over the next five to ten yearsHeart disease does not suddenly begin at age 70. It can develop silently during perimenopause, as arteries become stiffer, inflammation rises, metabolism shifts, and plaque begins to form. What you are feeling is not random. It may be your body signaling that something important is changing. This episode is a powerful reminder that prevention does not begin with a diagnosis. It begins when a woman listens to her body, understands her symptoms, asks better questions, and refuses to accept dismissal. You do not have to wait for something to go wrong before taking your health seriously. Become the CEO of your own health by treating your symptoms as signals, knowing your numbers, and protecting your heart before whispers become warning signs. Listen now, and share this episode with every woman in her 40s who has been told that what she is feeling is “just part of getting older.” Visit NitzaMD.com Follow @NitzaMD on Instagram and Facebook

    Can you have heart disease without blocked arteries? - Ep 75 - I AM YOU

    I AM YOU is hosted by Dr. Nitza I. Alvarez, MD, FACC — board-certified cardiologist, Women’s Heart Specialist, and bestselling author. Each episode shares real stories and expert insights to help women protect the heart that carries them through every stage of life — and step into their power as the CEO of their own health. In this Ask the Heart Doctor-style episode, Dr. Alvarez answers a critical question many women never hear explained clearly: can you have heart disease without blocked arteries? The answer is yes. Dr. Alvarez breaks down why women, especially around perimenopause and menopause, can experience chest pressure, shortness of breath, palpitations, fatigue, or feeling that “something isn’t right” — even after being told their stress test, echocardiogram, or arteries look normal. This episode reframes heart disease beyond the traditional blockage model. Dr. Alvarez explains how the heart is not only supplied by large arteries, but also by a network of small blood vessels that deliver oxygen to the heart muscle. When those small vessels do not relax or function properly, women can experience real cardiac symptoms even without major artery blockages. This is known as microvascular dysfunction. With clarity and urgency, she breaks down: • Why “clean arteries” do not always mean the heart is healthy • What microvascular dysfunction is and why it matters in women • How endothelial dysfunction affects blood flow, inflammation, and vessel flexibility • Why estrogen plays a major role in vascular health • How menopause-related hormonal changes can create early cardiovascular warning signs • Why symptoms like chest pressure, shortness of breath, palpitations, fatigue, indigestion, upper back pain, or neck discomfort deserve proper evaluation • Why women should ask whether doctors are evaluating function — not just blockages • The importance of early markers including blood pressure patterns, fasting glucose, hemoglobin A1c, fasting insulin, advanced lipid testing, ApoB, lipoprotein(a), vascular health, body composition, visceral fat, and hormone patterns. This episode is a direct reminder that women are too often under-recognized, under-diagnosed, and under-treated when it comes to heart disease. Normal tests do not always mean nothing is happening. Sometimes the earliest phase of cardiovascular disease begins as dysfunction, not obstruction. If you feel something is wrong, don’t dismiss it. Don’t stop at “your tests are normal.” Ask better questions. Push for a deeper evaluation. Becoming the CEO of your own health starts with taking your symptoms seriously — because you can have heart disease without blocked arteries.

    Hormones Are Not Just About Symptoms — Ep. 74 — I AM YOU

    I AM YOU is hosted by Dr. Nitza I. Alvarez, MD, FACC — board-certified cardiologist, Women’s Heart Specialist, and bestselling author. Each episode shares real stories and expert insights to help women protect the heart that carries them through every stage of life — and step into their power as the CEO of their own health. In this episode, Dr. Alvarez challenges one of the biggest misconceptions in women’s health: that hormones are only about hot flashes, mood changes, or reproductive symptoms. They are not. Hormones are deeply connected to the cardiovascular system — influencing sleep, heart rate, blood pressure, blood vessel function, inflammation, metabolism, cholesterol, insulin resistance, and the way the body responds to stress. Dr. Alvarez explains why subtle changes during perimenopause and menopause are often dismissed as “normal aging,” “stress,” or “nothing to worry about” — even when they may be early warning signs that the body’s cardiovascular regulation is beginning to shift. She breaks down why women may start noticing changes like lighter sleep, waking up around 3 AM, lower energy, palpitations, weight changes, blood pressure variability, or just feeling “off” — and why these symptoms should not be minimized. Dr. Alvarez explains: • Why perimenopause is not simply a decline in hormones, but a loss of stability in hormonal signaling  • How estrogen affects the brain, circadian rhythm, heart rate, stress response, arteries, blood flow, and vascular health  • Why symptoms like poor sleep, fatigue, palpitations, and weight changes may reflect deeper cardiometabolic changes  • Why normal labs do not always mean nothing is happening  • How insulin resistance, cholesterol changes, inflammation, blood pressure shifts, and vascular dysfunction can begin before standard tests look abnormal  • Why women should look beyond basic labs and consider markers like fasting insulin, advanced lipid testing, ApoB, lipoprotein(a), blood pressure patterns, body composition, visceral fat, and hormone patterns  • Why dismissing hormonal symptoms can lead to incomplete cardiovascular prevention This episode is a call for women to stop minimizing what they feel. Heart disease in women does not always begin with chest pain. Sometimes it begins with sleep disruption, palpitations, fatigue, weight changes, blood pressure changes, or a quiet sense that something in the body has shifted. Your symptoms are not random. They are signals. And prevention begins before disease shows up on a test. Visit NitzaMD.com  Follow @NitzaMD on Instagram and Facebook

    What Is Perimenopause Really? - Ep. 73 - I AM YOU

    I AM YOU is hosted by Dr. Nitza I. Alvarez, MD, FACC — board-certified cardiologist, Women’s Heart Specialist, and bestselling author. Each episode shares real stories and expert insights to help women protect the heart that carries them through every stage of life — and step into their power as the CEO of their own health. In this Ask the Heart Doctor-style episode, Dr. Alvarez reframes perimenopause as more than irregular periods, hot flashes, or poor sleep. What if perimenopause is not the beginning of the end of your hormones, but the beginning of your cardiovascular risk? And what if the symptoms women often dismiss — waking up at 3 a.m., feeling more anxious or irritable, fatigue, palpitations, blood pressure changes, or cholesterol shifts — are actually the body’s early warning signs? Dr. Alvarez explains that perimenopause can begin in the late 30s or early 40s, sometimes even earlier, and that estrogen does not simply decline — it fluctuates. These fluctuations affect the brain, nervous system, blood vessels, inflammation, sleep, metabolism, and cardiovascular health. With clarity and urgency, she breaks down: • Why perimenopause is not the same as menopause  • How fluctuating estrogen affects sleep, cortisol timing, heart rate, and the autonomic nervous system  • Why waking up around 3 a.m. may be more than stress or poor sleep hygiene  • How hormonal instability can affect blood vessels, nitric oxide, inflammation, and vascular tone  • Why blood pressure, cholesterol, insulin resistance, and body composition can begin changing before menopause  • Why women should not wait until something is “wrong” to evaluate their cardiovascular risk  • What a proper cardiometabolic profile should include, such as fasting glucose, hemoglobin A1c, fasting insulin, advanced lipid testing, blood pressure patterns, visceral fat, muscle mass, and hormone patterns This episode is a direct call-to-action: perimenopause is not something to ignore or simply push through. It is a critical window for prevention. If your body feels different, listen to it. Becoming the CEO of your own health starts with recognizing the signals early, asking better questions, and taking your cardiovascular future seriously.

    You’re Not Crazy — You’re Not Being Understood - Ep. 72 - I AM YOU

    I AM YOU is hosted by Dr. Nitza I. Alvarez, MD, FACC — board-certified cardiologist, Women’s Heart Specialist, and bestselling author. Each episode shares real stories and expert insights to help women protect the heart that carries them through every stage of life — and step into their power as the CEO of their own health. In this episode, Dr. Alvarez addresses a common experience for women entering perimenopause: feeling tired, anxious, disconnected, forgetful, or simply “not like yourself” — only to be told that it is stress, aging, or all in your head. These symptoms are not random, and women are not overreacting. During perimenopause, estrogen does not simply decline. It fluctuates unpredictably, affecting the brain, blood vessels, metabolism, inflammation, and cardiovascular system. This can contribute to brain fog, fatigue, mood changes, anxiety, and heart palpitations. Dr. Alvarez explains why women need to understand the connection between hormonal changes and heart health — and why waiting until something appears on a standard test may mean missing an important opportunity for prevention. With clarity and urgency, she breaks down:  • Why perimenopause can begin in a woman’s late 30s or early 40s — sometimes even earlier  • Why estrogen fluctuations can affect the brain, heart, blood vessels, and immune system  • Why symptoms such as fatigue, anxiety, brain fog, and palpitations are not simply signs of stress or aging  • Why up to 42% of perimenopausal women may experience palpitations  • How hormonal changes can increase inflammation and contribute to cardiovascular risk  • Why standard lab results may not capture what is happening during this transition  • Which cardiometabolic markers women should discuss with their doctors, including glucose, insulin, hemoglobin A1c, blood pressure, lipid profiles, ApoB, and lipoprotein(a)  • Why body composition matters beyond weight and BMI — including waist circumference, visceral fat, body fat percentage, and lean muscle mass  • Why hormonal and thyroid markers should also be considered as part of a more comprehensive evaluation This episode is a reminder that prevention begins before a heart attack, before permanent damage, and before something abnormal appears on a test. It begins when your body starts signaling that something has changed. You do not need to wait for something to go wrong to take your health seriously. Listen to your body, ask the right questions, and step into your role as the CEO of your own health. Visit NitzaMD.com Follow @NitzaMD on Instagram and Facebook
