Background: Dysfunctional uterine bleeding (DUB) is a major form of abnormal uterine bleeding, seen in at least 10% of all new outpatient department patients. The thyroid gland is known to play an important role in maintaining a healthy menstrual cycle.
Aims: To assess the thyroid hormone status in apparently euthyroid patients with DUB and to correlate it with incidence of DUB.
Materials and methods: Fifty DUB patients were selected on the basis of clinical history, examination, and relevant investigations. Equal numbers of age-matched women with normal menstrual cycle were taken as controls. Thyroid hormones, viz., thyroidstimulating hormone, total triiodothyronine and tetraiodothyronine, were estimated by radioimmunoassay. Statistical analysis of the data was performed by using Microsoft Excel software.
Results: The most common menstrual abnormality was menorrhagia (48%) followed by metrorrhagia and polymenorrhea (14% each). Hypothyroidism was more prevalent among cases (85.7%) as compared with controls (14.3%). In patients with menorrhagia, 33.3% of patients had hypothyroidism.
Conclusion: Hypothyroidism occurs in DUB patients commonly. There is a need for mandatory thyroid screening in all patients with menstrual irregularities to help in early detection of the cause and treatment of DUB patients to avoid surgery.
