Aim: The purpose of this study is to determine the prevalence of clinical and biochemical thyroid dysfunction in children with type 1 diabetes. A relationship between type 1 diabetes and thyroid dysfunction has been reported globally. Place and Duration: In the department of Paediatric Endocrinology, Children Hospital Lahore for one year duration from May 2018 to May 2019. Methods: A total of 116 children with type 1 diabetes (62 men and 54 women), aged 1 to 16 years, were examined for signs of thyroid dysfunction and thyroid size was assessed by palpation and TSH, T3 and T4 were measured to assess the incidence of thyroid dysfunction. Results: the incidence of thyroid dysfunction in diabetics was 12.93%, 6.9% of them were subclinical hypothyroidism, 3.4% of them had hypothyroidism, and 0.86% had hyperthyroidism, 1.7% showed hyperthyroidism, sex distribution showed 27% men and 73% women with thyroid dysfunction, which means a higher than normal population in the same age group. The incidence of goiter due to palpation was in 9.5% of diabetics, which is associated with poor consumption of iodized food. Conclusion: We conclude that the frequency of thyroid dysfunction is higher in type 1 diabetes than in the normal population, we recommend a routine thyroid test at the time of diagnosis of children with type 1 diabetes.
