Hi Giovanni,
Your MCV is low and your RBC is high, which both show that thal minor is probably present. I am sure this has been confirmed by hemoglobin electrophoresis. The RDW is normal, which is good and means you do not have iron deficiency. Your Hb level is also normal, which is also good for thal minor.
From your bio, I see that you are beginning to see health issues, in spite of the normal Hb level. This is because thalassemia is more than a lack of hemoglobin. Because the bone marrow is overactive in thal minors, many defective red blood cells, RBCS are produced, which are then destroyed by the body. In addition, in beta minor, there is a deficit of beta globin, so there is not enough beta globin to match the alpha globin that is produced, resulting in excess alpha chains that form tetramers that cause oxidation in the body. Both the bits of defective red blood cells and alpha tetramers are debris that cause problems in the bloodstream and we see poor circulation to the extremities as a noticeable result of this. This will be seen in numbness and cold in the extremities. I believe it also has something to do with the mind not being as sharp as it should be sometimes, and this is caused by poor circulation, which means less oxygen to the brain and other organs.
Thalassemia also causes depletion of many nutrients. My focus for thal minors is always based in understanding the nutritional needs of minors and addressing those needs. The section of this website on nutrition in thal minors can be very useful. From your bio, I would immediately suggest once weekly large doses of vitamin D, unless you get regular daily sunshine (I take 50,000 IU once weekly), 400 IU natural vitamin E daily (I recommend to all thals) and at least 500 mg of vitamin C daily (very important for blood vessel health). Vitamin B-12 and L-methylfolate can be very helpful in fighting fatigue. I don't carry thal, but as I get older, I find my thyroid fatigue wears me out unless I take both B-12 and Folate daily.
Look over the section on nutrition and make sure your diet is a source of nutrition and not empty calories. As you get older, you'll do much better if you start paying more attention to nutrition now.
