ABSTRACT
Thyroid gland hormones are highly implemented in the pathogenesis of dysfunctional uterine bleeding [1] The clinical profile may cast light on that link but other times the patient seems euthyroid with normal T[3]; however T[4], TsH and LH may show minor errors. Other laboratory profiles pertinent to hypothyroidism confirm the scepticism. Endometrium biopsies 46.7% showed proliferative endometrium, 43.3% had a cystic glandular hyperplasia while 10% had secretory type of endometrium. There was no correlation between the type of endometrium and thyroid function tests. We conclude that careful examination and laboratory investigations [thyroid function tests] for patients with menorrhagia helps to diagnose early cases of hypothyroidism and so their early treatment with thyroid replacement therapy
