Abnormal Uterine Bleeding (AUB) and Thyroid Function in Chhattisgarh

Abnormal function of thyroid gland is associated with a disturbance in the menstrual cycle. However, in clinical practice, thyroid dysfunction is frequently overlooked as a possible etiology and therefore, the importance to investigate thyroid function in asymptomatic cases is under- recognized in India. Treating thyroid dysfunction in such cases can reverse the menstrual abnormality, thus avoiding unnecessary hormonal therapy or in long term, hysterectomy. This article is intended to determine the prevalence of overt and subclinical forms of hypothyroidism/hyperthyroidism among women with abnormal uterine bleeding (AUB) in a known iodine-deficient state of India, Chhattisgarh. Moreover, the aims included to characterize the types of menstrual abnormality with thyroid dysfunction in study participants. The present study found a prevalence of thyroid dysfunction in one out of five cases of menstrual abnormality, most common dysfunction being hypothyroidism. An appreciable proportion of thyroid disorder was found in patients with menorrhagia, oligomenorrhea, polymenorrhea and amenorrhea.
