Elevated ferritin in PCOS isn’t always as simple as “too much iron” 🔬✨ Repost Dr. Laura von Hagen, M.Sc, Fertility ND 👌.
As a Toronto ND with a clinical focus on PCOS, I often explain that ferritin can rise in PCOS for multiple reasons; and understanding the “why” matters.
Here are 3 major drivers 👇
💥 Insulin resistance
This appears to be one of the biggest contributors. Higher insulin levels may increase iron absorption and storage in the body. Interestingly, studies show ferritin levels can improve when insulin sensitivity improves.
🩸 Irregular or missing periods
Many people with PCOS experience oligomenorrhea or amenorrhea, meaning less monthly blood loss — and therefore less iron loss over time.
🔥 Chronic low-grade inflammation
PCOS is associated with ongoing inflammation, which can raise ferritin as part of the body’s inflammatory response, even when true iron overload isn’t present.
This is why elevated ferritin should always be interpreted in context 🧠
Looking at markers like transferrin saturation, CRP, symptoms, and metabolic health can help paint a much clearer picture.
Let’s decipher your whole picture.
