When “Anxiety” Is Actually a Hormone Signal – Ep. 66 – 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 tackles one of the most misunderstood symptoms many women experience in their late 30s and 40s: sudden anxiety. If your heart starts racing, your chest feels tight, your mind starts spinning, or you wake up at night with nervous energy, you may have been told it is “just stress” or “just anxiety.” But what if your body is actually sending a hormone signal?

Dr. Alvarez explains why anxiety-like symptoms can appear during perimenopause, even when nothing major has changed in your life. As estrogen and other hormones begin to fluctuate, they can affect the brain, nervous system, blood vessels, sleep, and even the heart. What feels emotional may actually be physiological.  

With clarity and compassion, she breaks down:

• Why hormones are not just about reproduction — they are communication signals throughout the body
• How estrogen interacts with serotonin, dopamine, the nervous system, blood vessels, and the heart
• Why women can become more sensitive to stress, caffeine, poor sleep, and heart palpitations during hormonal shifts
• Why perimenopause can begin earlier than many women realize, sometimes in the late 30s
• Why palpitations are often benign, but should still be evaluated when they are new or disruptive
• The minimum tests women should know about, including thyroid testing, complete blood count, ferritin/iron levels, blood sugar markers, hemoglobin A1c, and lipid panel
• Five practical steps women can take: tracking symptoms and cycles, prioritizing sleep, strength training, reducing caffeine, and advocating for themselves during medical visits

This episode is a powerful reminder that anxiety is not always weakness, and it is not always “all in your head.” Sometimes it is information. Sometimes it is your nervous system responding to real changes happening inside your body. And when women understand those signals early, they can stop blaming themselves and start asking better questions.

Because becoming the CEO of your own health starts with listening to your body — and taking your symptoms seriously.
