Abstract

Hypothyroidism is most common endocrine disorder resulting in decreased levels of thyroid hormones. Hypothyroidism can be divided into primary, central and congenital hypothyroidism. Iodine deficiency is the most common cause of primary hypothyroidism. In areas with sufficient dietary iodine, most common cause is hashimoto’s thyroiditis. Materials and Methods: Patients attending the OPD and those admitted in wards of Department of General Medicine at a tertiary centre, Bangalore who are newly diagnosed with non diabetic hypothyroidism are selected for the study as cases. The healthy individuals who are age and sex matched to cases are taken as controls. Study is carried out for the period of 18 months from November 2015 to April 2017. Results: A total number of 200 subjects were studied which included:  100 Controls  100 patients with newly diagnosed non diabetic hypothyroidism. Discussion: Hypothyroidism is defined as decreased levels of thyroid hormones in blood due to underactive thyroid. The thyroid gland produces hormones that regulate the body's metabolic rate as well as heart and digestive function, muscle control, brain development and bone maintenance. Conclusion: From this study it can be concluded that newly diagnosed non diabetic hypothyroid patients show elevated glycated hemoglobin levels in spite of normal fasting blood sugar levels.
