Subclinical hyperthyroidism as a potential factor for dysfunctional uterine bleeding

ABSTRACT

To evaluate the functional status of thyroid gland in apparently euthyroid women with dysfunctional uterine bleeding. Forty apparently euthyroid women with menorrhagia and no pathologic lesion in the genital tract were compared to 20 women having normal menstrual cycle as control group. All women were subjected to hormonal assay total and free T3, T4 and TSH, Serum PRL, P [progesterone], total and free testosterone. A statistically significant difference in the values of TSH, total T3, free T3 and total T4 in the menorrhagia group compared to the control group. Prolactin was decreased significantly in the menorrhagia group. Subclinical hyperthyroidism can be a potential risk factor for dysfunctional uterine bleeding. Other studies are needed to confirm our findings:
