Correlation between Thyroid Disorder and Pattern of Menstrual Bleeding in Women with Abnormal Uterine Bleeding

Objective- To study the correlation between thyroid disorder and pattern of menstrual bleeding in women with abnormal uterine bleeding. Methods- The present study was conducted on 50 women with complaint of abnormal uterine bleeding and thyroid disorder. After detailed history and examination, Pap�smear was taken. Routine blood investigations, thyroid profile (TSH, FT3, FT4,) was done by Chemiluminescent Microparticle Immunoassay (CMIA) technology. Transvaginal ultrasound was done to visualize the uterus and adnexal region. Result- Among 50 women, 40 (80 %) were hypothyroid, 10 (20 %) patients were hyperthyroid. Among hypothyroid, maximum cases 12 (30 %) had heavy menstrual bleeding, followed by frequent cycle in 10 (25 %) cases. Among hyperthyroidism, maximum cases 4 (40 %) had scanty menstrual cycle. Conclusions: HMB 12 (24 %) was found to be the commonest presenting abnormal uterine bleeding pattern followed by frequent menstrual cycle 10 (20 %). Among thyroid disorders, prevalence of hypothyroidism was more than hyperthyroidism. Commonest bleeding pattern in hypothyroidism was HMB and in hyperthyroidism was scanty menstrual cycle.
