The subjects of present study were 42 healthy Jordanian male students who fasted during Ramadan. Their mean age was 21±1.6 years. We evaluated some anthropometric parameters as body weight (kg), pulse rate (per min) and systolic and diastolic blood pressure (mmHg). All parameters at forth week of Ramadan were significantly lower than pre-Ramadan values. We evaluated blood glucose, triglycerides (TG), cholesterol, low-density lipoprotein LDL) and high-density lipoprotein (HDL) and Triglycerides at 1 day before, at week 1, 2 and 4 of the Ramadan month. It was found that high-density lipoprotein (HDL) cholesterol increased significantly during Ramadan, which indicated positive association with pulse rate and fat intake and negative association with systolic blood pressure and weight. The LDLc was significantly reduced at the end of fasting. A reduction in the average TC value was observed at the end of fasting but the difference was not statistically and there no significant rise in the TG and blood sugar values at the end of fasting. This study indicated that Ramadan fasting led to a decrease weight, LDLc significantly and significant not statistically reduction in the average TC value and significantly increasing in HDLc was noted during Ramadan. There was a non-significant rise in the TG and blood sugar value at the end of fasting. We measured blood hormone levels of testosterone luteinizing hormone (LH), follicle-stimulating hormone (FSH) and thyroid hormones (T3, T4) in all subjects of our study who were fasting for ≥12 h during Ramadan. Testosterone level was lower, significantly so for the second and fourth week of the month (p<0.05); FSH was increased, significantly for the fourth week (p<0.05); LH did not change significantly. There were no significant changes in T3 after Ramadan fasting. Short fasting is not probably accompanied by significant changes in thyroid hormone, but the repetitiveness of this in Ramadan fasting mild decrease in T4 level.]]>Abbas, S.M. and A.H.
