Clinical study of hypo/hyper thyroidism in dysfunctional uterine bleeding

Background Dysfunctional uterine bleeding is one of the most frequently encountered condition in gynaecological practice. Thyroid hormones play a key role in the menstrual and reproductive function of women and thus thyroid dysfunction results in menstrual disturbances. The objective is to study the prevalence of thyroid disorders in patients with dysfunctional uterine bleeding.

Methods This is a hospital based prospective observational study done in the department of Obstetrics and Gynaecology, Vijayanagara Institute of Medical Sciences, Ballari. The study period is from February 2016 to August 2016. In the study, 100 patients with dysfunctional uterine bleeding were included and evaluated for thyroid abnormality.

Results Among 100 patients with DUB, thyroid disorders were prevalent in 24 % of patients. Hypothyroidism was present in 22% and hyperthyroidism in 2% of the women with DUB. The commonest menstrual complaint associated with hypothyroidism was menorrhagia, seen in 54.54% of cases. In 2 patients with hyperthyroidism one each had menorrhagia and metropathia haemorrhagica.

Conclusions Thyroid dysfunction is one of the important cause for DUB. Hypothyroidism is more commonly associated with DUB than hyperthyroidism. Evaluation of thyroid status is important in all patients with DUB to avoid unnecessary surgical interventions.
