Hypoparathyroidism is rare atypical clinical consequence of iron overload in patients of Beta thalassemia major (BTM) who are on regular blood transfusions. We report a case of 22 yr old male who presented with generalized tonic clonic seizures. Laboratory investigations showed anemia, hypocalcemia, hypophosphatemia with very low serum parathyroid hormone (PTH) level. Patient was started on calcium and vitamin D supplementation.Serum calcium levels were optimized. The patient gradually improved with no further episodes of seizure. Rarity of this endocrinopathy in beta thalasemia major made us report this case.
