Objective:To determine the effects of Ramadan fasting on serum levels of stress neurohormones in Iranian women with polycystic ovary syndrome (PCOS).
Materials and methods:This study was a clinical trial and was performed during July 2011 (month of Ramadan) in Royan institute, Tehran. A total of 40 women who were aged 20-40 years and known cases of PCOS and had no other medical diseases were included in the study. They were divided into two groups as follows: (i) study group (n = 20) who participated in Ramadan fasting and (ii) control group (n = 20) who did not participate in fasting. For evaluating Ramadanʹs effect on the level of neurohormones serum level of the following variables were evaluated before and after Ramadan: cortisol, adrenaline (A), noradrenalin (NA), beta-endorphin (β-End), insulin, as well as sex hormones including follicle-stimulating hormone (FSH), luteinizing hormone (LH), and testosterone.In the study group after Ramadan serum cortisol and nor-adrenaline levels were significantly lower than the initial levels obtained at beginning of Ramadan (p < 0.05) as compared to control group.
Conclusion:This study indicates that Ramadan fasting decreases stress neurohormones in women with PCOS.
