“…This questionnaire was previously used to study the prevalence of gynecological disorders and menstrual cycle lightheadedness in women with postural tachycardia syndrome (POTS) [12]. The questionnaire asks subjects about the following five subject categories: 1) current reproductive status; 2) detailed menstrual cycle history with information about the length and heaviness of the flow, irregularity in bleeding patterns, faintness during various phases of the cycle, and the intensity of premenstrual symptoms; 3) preexisting gynecological disorders; 4) medication history with special emphasis on the use of hormonal contraceptives, hormone replacement therapy (HRT), and changes in fainting while on medication; and 5) detailed obstetrics history encompassing pregnancy abnormalities, complications, and history of fainting during the pregnancy trimesters.…”
