Type 2 diabetes (maturity onset diabetes) occurring in and around the age of 40 is also showing a rising trend in thyroid dysfunction. Present work in Saharanpur (U.P.) India was carried out to know the relationship if any between the two disorders. Thyroid function in normal groups and type 2 diabetic patients were carried out. Biochemical parameters such as – fasting plasma glucose TSH (Thyroid stimulating hormone), T3 (Triidothyronine), T4 (Thyroxin) were measured in different groups for assessment. The study showed the subclinical cases of hypothyroidism are at risk for type 2 diabetes.
