Hi @berbatti Is this a recent diagnosis for you? Thalasemia is an inherited blood disorder. I found some information on the Mayo Clinic website regarding Thalasemia which you may find useful in explaining your condition.

Here’s an excerpt from the article about the potential for too much iron for people with Thalasemia.
“People with thalassemia can get too much iron in their bodies, either from the disease or from frequent blood transfusions. Too much iron can result in damage to your heart, liver and endocrine system, which includes hormone-producing glands that regulate processes throughout your body.”

Have you required any blood transfusions? May I ask why your doctor feels you need an iron infusion? Do recent blood test results indicate that your iron level is low?
