A controlled study on the prevalence of underactive thyroid in type 2 diabetes

Abstract

Background: The term "thyroid diabetes" depicts the effect of excess thyroid hormones in the progressively worsening glucose control. Subclinical hypothyroidism is most commonly present in females than males, reaching a prevalence of up to 20% in older females. Hashimoto's thyroiditis and Graves' disease are the principal causes of hyper-and hypothyroidisms. Objectives: (1) To study the prevalence of hypothyroidism in diabetes and to evaluate the etiologic evidence of triglycerides on prevailing cardiovascular risk and metabolic syndrome. (2) To determine the mean levels of fasting blood sugar (FBS), HbA1c, triiodothyronine, serum thyroxin, and thyroid-stimulating hormone. (3) To evaluate the hemoglobin levels and to establish the prevalence of anemia in diabetic patients with hypothyroidism. (4) To determine the mean age and male/female ratio in diabetic patients with hypothyroidism.
