Abstract
BACKGROUND: To our knowledge, no reports are available indicating the effects of Ramadan fasting on metabolic parameters, inflammatory factors and oxidative stress in polycystic ovary syndrome (PCOS). The current study was designed to evaluate the effects of Ramadan fasting on metabolic status among women with PCOS. METHODS: This cross-sectional study was conducted on twenty seven PCOS patients who had fasted for a mean period of 16.5 hours a day during the 29 days of the month of Ramadan in Kashan, Iran. Fasting blood samples were collected at the beginning of the study and after 29 days of the study to quantify related variables. To identify within-group differences (before and after Ramadan), paired-samples t-tests were used. RESULTS: Plasma nitric oxide (NO) levels in PCOS women after Ramadan fasting were significantly higher compared to the baseline values (70.63 ± 15.78 vs. 59.94 ± 13.87 μmol/L, P = 0.003). Post-Ramadan levels of plasma glutathione (GSH) increased significantly in comparison with pre-Ramadan (974.95 ± 414.20 vs. 746.96 ± 205.93 μmol/L, P = 0.011). In addition, a trend toward a significant effect of Ramadan fasting on reducing serum high sensitivity C-reactive protein (hs-CRP) concentrations (2001.07 ± 1686.08 vs. 2962.72 ± 2845.21 ng/mL, P = 0.072) was seen. We did not observe any significant effect of Ramadan fasting on glucose hemostasis parameters, lipid profiles or total antioxidant capacity (TAC). CONCLUSION: In conclusion, Ramadan fasting in women with PCOS for 4 weeks had beneficial effects on NO and GSH levels, but did not affect glucose hemostasis parameters, lipid profiles or TAC.
