Is there a connection between iron levels and cholesterol?

Is iron overload linked to higher cholesterol?

Iron overload disorders such as hemochromatosis can raise LDL cholesterol and total cholesterol levels. Excess iron promotes oxidative stress that alters lipid metabolism and may increase the risk of cardiovascular disease.

Why do researchers associate iron with lipid metabolism?

Iron participates in several steps of cholesterol synthesis and transport. Studies show that iron deficiency lowers LDL and very-low-density lipoprotein levels, while iron supplementation can increase those values in anemic patients. Animal models demonstrate that iron restriction reduces cholesterol synthesis enzymes.

What happens if you treat iron overload?

Phlebotomy or iron chelation therapy lowers both iron stores and cholesterol. Patients with hemochromatosis who undergo regular blood removal show drops in LDL and triglyerides alongside iron reduction. Some clinical reports note improvements in lipid panels after only a few months of treatment.

Can low iron levels affect cholesterol readings?

Iron deficiency anemia correlates with lower total cholesterol and LDL in multiple population studies. The connection appears bidirectional: low iron slows lipid synthesis in the liver, and low cholesterol states can accompany severe anemia.
