Background: Polycystic ovary syndrome (PCOS) is a complex heterogeneous endocrine
disorder associated with reproductive morbidity, including menstrual dysfunction and infertility. A
quasi experimental intervention study aimed at assessing the effect of lifestyle modification
counseling on polycystic ovarian syndrome symptoms compared to medical treatment metoforamin
only on PCOs symptoms. The study was conducted in outpatient gynecological/infertility clinic at
Ain Shams Maternity University hospital. Purposive sample of 172 cases were enrolled, inclusive
criteria; Women medically diagnosed with polycystic ovarian syndrome, reproductive age (18-
40yrs), Married Women, overweight & obese women, Women with menstrual dysfunction. Tools
used for data collection consisted of Arabic Structured Interviewing questionnaire, Two Arabic
Weekly logs to record regularity of diet & exercise, Woman's follow up card to record measures
changes pre/post intervention. Results revealed that there was highly statistically significant
difference between post intervention of the two groups regarding Weight loss, Waist circumference
(CM), Hip circumference (CM), and Waist and hip ratio, LH: FSH ratio and fasting serum insulin in
(G1) lifestyle modifications. But there was insignificant difference between post interventions of the
two groups regarding menstrual dysfunction. In conclusion, the present study drew attention to
critical point that lifestyle modification with weight loss leads to improved hormonal profile, which
restores ovulation resulting in improving menstrual function & relieving PCOs symptoms. The
study recommended detect center for PCOS cases inside infertility/gynecological clinics to ensure
lifestyle modification, Future research should focus on the optimal dietary strategies and exercise
regimens for PCOS treatment and the relative efficacy and appropriate use of lifestyle management
versus anti-obesity pharmacologic agents and surgery.
