Assessment of iodine and non-iodine deficiency hypothyroidism in women of reproductive ages in the Sub-Himalayan plains of west Bengal.

ABSTRACT

Indian women of reproductive age groups commonly suffer from hypothyroidism which may be due to iodine or non iodine deficiency causes. This study was undertaken with a view to ascertain the leading cause of hypothyroidism in women of reproductive age group residing in the sub-Himalayan plain areas of Darjeeling district of West Bengal. Serum TSH, T4, T3 and Urinary Iodine Excretion (UIE) levels were measured in 101 non pregnant women. Our results reveal that among 37.62% (n=38) of bio-chemically established hypothyroid women; majority 76.32% (n=29) are suffering from iodine deficiency and the rest 23.68% (n=9) have Hypothyroidism due to other causes. Moreover, iodine deficiency persists among 57.42% (n=58) of the women in our study. We conclude that iodine deficiency disorders are still a major problem in this region and hypothyroidism due to iodine deficiency is more prevalent than the non iodine deficiency causes. Hence lacunae in the iodine supplementation process needs to be reviewed.
