OBJECTIVE: To find the incidence of systemic causes of menorrhagia with special emphasis on careful history taking, clinical examination and inclusion of simple blood tests to diagnose hemostatic disorders. METHOD: Thirty two women with menorrhagia of 15-45 years age, without any pelvic cause and treated from 1st January, 2011 to 31st December, 2011 were recruited for this study. After a detailed history and general examination all patients were subjected to blood tests for complete blood count, bleeding time, prothrombin time, activated partial thromboplastin time (aPTT) and serum T3, T4, TSH levels. Special tests were reserved, wherever applicable, to diagnose the cause of menorrhagia. Results were analyzed statistically by 2 x 2 chi square test. RESULTS: Hypothyroidism (25%) and inherited coagulopathy (18%) were the two most common nonpelvic causes of menorrhagia. Menorrhagia from menarche (P<0.001), bleeding from other sites (P=0.007), history of previous operative bleeding (P<0.001), and history of postpartum bleeding (P<0.001) were statistically significant in patients with underlying hemostatic disorders.
CONCLUSION(S):A detailed history, clinical examination and simple blood tests can detect systemic causes of menorrhagia.
