Aim:
The aim of this study was to determine the effect of Ramadan fasting on blood pressure (BP), fatigue, sleeping and physical activity among hypertensive patients.
Subjects And Methods:
A cross-sectional study was conducted from April 2019 to July 2019. Of the total 1500 hypertensive patients approached, 1118 (74.5%) gave their consent. Data analysis included sociodemographics, lifestyle habits, anthropometric measurements and clinical biochemistry parameters at baseline, and after 3 months.
Results:
Out of 1118 subjects, 593(47.6%) were male and 653(52.4%) were female. There were statistically significant differences between males and females regarding age groups in years, educational level, occupational status, income, smoking habits, physical exercise, sports activities and fatigue. There were statistically significant differences for the biochemistry parameters regarding vitamin D, blood glucose, HbA1c level, creatinine, bilirubin, albumin, total cholesterol, triglycerides, HDL-C, LDL-C, uric acid and SBP for both males and females after the holy month of Ramadan as compared to before Ramadan. Also, BMI was significantly lower during the after month of Ramadan as compared to before Ramadan (P < 0.001). Multiple linear regression analysis results revealed that less hours of sleeping (P < 0.001), SBP (mmHg) (P < 0.001), DBP (mmHg) (P < 0.001), family size (P = 0.002), obesity BMI (kg/m2) (P = 0.013), fatigue (P = 0.022) and smoking cigarette (P = 0.029) were identified as statistically significant predictors of hypertensive patients with Ramadan fasting as contributing at higher risk factors.
Conclusion:
This study confirmed that fasting during Ramadan has no effect on the BP, blood glucose, HbA1C level, sleep quality, fatigue and BMI among hypertensive patients.

Blood Pressure
The average BP in an adult is typically around 120/80 mmHg (millimeters of mercury). In this measurement, the numerator (120) indicates the systolic pressure, which is the pressure in the arteries during the contraction of the heart's ventricles as blood is expelled. The denominator (80) represents the...
