Iron Deficiency in Women: The Hidden Cause of Fatigue, Brain Fog & Heavy Periods

Hello. This week I decided to re‑air an important episode of GynoInfo because iron deficiency in women is something I see every single day in my practice — and it is so often missed.So many of my patients come in feeling exhausted, foggy, overwhelmed, short of breath, losing hair, or just not like themselves. And almost every time, they assume it’s stress, aging, hormones, or “just being busy.”But very often? It’s low iron.Iron deficiency — with or without anemia — is incredibly common in women, especially if you have heavy periods, are pregnant or postpartum, follow certain diets, or have ongoing blood loss. And yet, so many women are told their labs are “normal” and sent on their way.That’s exactly why I wanted to bring this episode back.In this conversation, I break down:What iron deficiency actually isThe difference between iron deficiency and iron‑deficiency anemiaWhy women are especially vulnerableThe symptoms of low iron that often get dismissedThe blood tests I rely on — including CBC, ferritin, and CRPWhy ferritin levels matter more than many women realizeTreatment options, from iron‑rich nutrition and oral supplements to IV iron infusions when neededThis is such an important women’s health topic because iron impacts everything — your energy, brain function, mood, hair, immune system, and overall quality of life.If you’re constantly tired…If your periods are heavy…If you’ve been told your labs are “fine” but you don’t feel fine…This episode is for you.I’m re‑airing it because this message needs to reach more women. Too many are walking around iron deficient and don’t know it. And the fix can be life‑changing.My goal is always to empower you with real information so you can advocate for yourself, ask better questions, and take control of your health.Iron deficiency in women is common. It’s treatable. And it deserves attention.This is one conversation every woman should hear.You can write to us at [email protected] follow us on Instagram @gynoinfo
