SUBTLE FACETS OF HYPERTHYROIDISM IN CHILDREN: EASY FATIGABILITY AND PALPITATION AS PRIMARY MANIFESTATIONS.

Background: Thyroid hormone deficiencies or excesses are known to have a wide range of impacts on different organ systems. According to the American Thyroid Association, hyperthyroidism is defined as subnormal (often undetectable) serum thyrotropin (TSH) with high serum levels of free thyroxine (FT4). With over 95% of cases, Graves' disease is the most frequent cause of hyperthyroidism, with Hashimoto's disease in children coming in second. Based on compelling scientific data, hyperthyroidism is a rare but potentially dangerous childhood illness that, if left unchecked, can cause a wide range of problems, including effects on development and growth. History, physical examination, and thyroid function test are used to diagnose hyperthyroidism based on some study evidence and consensus. A 16- Case Report: year-old male child presented with weakness and poor appetite along with palpitation. He was provisionally diagnosed with Iron deficiency Anaemia. Haematopoietic medication was chosen as the initial treatment for Iron Deficiency Anaemia. However, this treatment failed to normalize the patient symptoms. We further evaluated patient's thyroid profile, his TSH was significantly reduced and T3 & T4 were elevated suggestive of diffuse toxic goitre. This Conclusion: case report highlighted a rare case of hyperthyroidism in male child that may only manifest as easy fatiguability and palpitations.
