B-Thalassemia major (b-TM) is a hereditary ،anemia resulting from defects in the production of b-globin chains and is one of the most common genetic disorders worldwide.

The clinical classification of thalassemias is currently widely applied in clinical practice related to transfusion requirements Transfusion-dependent thalassemia (TDT) is defined as a condition where patients cannot produce adequate hemoglobin to survive without blood transfusion. Non-transfusion-dependent thalassemia (NTDT) is a descriptive term for patients who do not require regular lifelong transfusions. They may require intermittent or frequent transfusions in certain clinical situations.

Patients with β-thalassemia intermedia have symptoms in between carriers and those with β-thalassemia major.

Endocrine complications are the commonest among BTM patients and the attributing factor is iron deposition in endocrine organs due to frequent blood transfusions along with suboptimal iron chelation. Thus, keeping an iron level within the useful and safe range is critical since a low amount can cause anemia, while a high level can cause tissue damage Background pathophysiologic mechanism leading to DM in TM is unclear; some regard the iron induced pancreas cytotoxicity as the most significant contributor, a new hypothesis suggests the exhaustion of beta pancreatic cells subsequent to a chronic period of hyperinsulinemia .There are 5% of thalassemia patients develop clinical hypothyroidism that requires treatment, a bigger number of them develop subclinical compensated hypothyroidism with normal T3 and T4 levels but high TSH serum levels.

The TDT is also associated with altered lipid levels because of oxidative stress that can lead to early atherosclerosis, adding to the morbidity and even early mortality.
