Hi Andy, kindly share your comments on this post as well. I've included blood work results. My almost 12 year old son's main goal is more bone growth and putting on more weight.

Some parents in similar situation (non-thal minor) are doing Human Growth hormone injections. Some also worked on better gut health and digestion.

Is any more blood work needed for TIBC and Iron ? Should we add more Iron rich foods ?

Thank you!

Yes, alpha minors can react to certain substances that can cause hemolysis and cause the hemoglobin level to suddenly drop.

This is the same drug as Luspatercept, which has been used with some success by many US patients. It does not suit everyone or work for everyone, but it is definitely worth trying to see if it can help individual patients maintain a higher Hb level and reduce their transfusion needs.

What I would point out is that all humans need iron, and that there are many thal minors with iron deficiency, more commonly in females than males. Iron from veg foods is not well absorbed, and no more than 40% of the available iron is absorbed, as opposed to the very high percentage of iron that is absorbed form meat. I never advise avoiding most veg sources of iron.
Both carnitine and arginine have very similar properties and both can help fix nitric oxide in the body. This is extremely important to the health of the circulatory system.

I don't think more testing is needed. A wholesome diet and good quality supplements are a good approach to living with thal minor.
