RESUMO
To find out causative factors of adolescent menorrhagia and success of various treatments. Descriptive cross sectional study Lady Willingdon Hospital, Lahore from May 2004 to April 2005. Fifty unmarried patients at 12-19 years with menorrhagia selected by non-probability convenience sampling. Blood loss was determined by duration of bleeding extending beyond seven days, passage of clots and presence of anaemia. The most common cause of menorrhagia was DUB [92%] followed by bleeding and endocrinal disorder. Non-steroidal anti-inflammatory drug and antifibrinolytic agent produced 75% subjective improvement in complaints. However, combined oral contraceptive produced 66% improvement. NSAIDS and antifibrinolytic drugs were found to be effective in reducing menstrual loss and should be used as first line of treatment
