Evaluation of Thyroid Dysfunction in Abnormal Uterine Bleeding

Abstract

Introduction: Abnormal uterine bleeding (AUB) is a common clinical presentation in gynecology. Alteration in thyroid hormones level has been associated with menstrual disturbances. The objective of this study was to study the correlation between thyroid disorders and abnormal uterine bleeding in women of reproductive age group.Method: 100 Patient of clinically diagnosed AUB were taken from gynecology OPD. All the patients from 15 to 45 age groups presenting with menstrual disturbances underwent thorough clinical examination, ultrasonography and thyroid function tests.Result: Out of 100 women of AUB,  majority were in the age group of 31-40 years (41%), 50% were multiparous and 46% presented with menorrhagia. 68% were euthyroid, 17% had subclinical hypothyroidism, 12% had overt hypothyroidism and 3% were dignosed as hyperthyroid. Subclinical hypothyroidism, overt hypothyroidism and hyperthyroidism were detected mostly in the age group of 31-40 years. The commonest bleeding abnormalities in hypothyroid patients were menorrhagia and olygomenorrhoea. While most of the hyperthyroid cases were oligomenorrhoic.Conclusion: Our study concludes that thyroid dysfunction should be considered as an important etiological factor for menstrual abnormalities. Hence while investigating a patient with AUB, evaluation of thyroid function forms an essential component.
