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 reactions
• Why small frustrations may suddenly feel intolerable
• How hormonal changes can contribute to relationship conflict
• Why declining estrogen and testosterone can reduce libido
• How inflammation affects both the brain and the cardiovascular system
• Why therapy may be valuable—but should sometimes be accompanied by a hormonal evaluation
• Why low libido should not automatically be dismissed as normal aging
• How changes in mood and relationships may signal broader hormonal, metabolic, and cardiovascular changes

Dr. 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.
