Frequency of Florid Hyperthyroidism In Patients Taking Iodinated Salt

Thyroxin a vital hormone for life lot of body functions depend on proper functioning on pituitary thyroid axis. it exists in two major forms Thyroxine (T4) and (T3) , each of them containing two iodine atoms on their inner (tyrosine) ring. Synthesis of reasonable quantities of thyroid hormones requires adequate iodine intake to allow sufficient thyroidal uptake. The World Health Organization (WHO) recommendation for daily intake of iodine is 150 μg for children ≥12 years and adults, and 250 μg for pregnant and lactating women. However as we know optimum amount of iodine is required for normal pituitary thyroid axis like wise excessive intake may cause over functioning of axis hence over production of hormone that can be manifested both clinically and biochemically. This study is designed to observe the frequency of over hyperthyroidism in patients taking iodinated salt.
