Abstract

Fasting in the month of Ramadan is an obligatory duty for muslims. Researchers have investigated health benefits of fasting and reported conflicting results. The purpose of this study was to determine the immediate and delayed effects of Ramadan fasting on spirometric parameters. 50 apparently healthy young adults aged between 17-27 years, belonging to both genders who fast during the month of Ramadan were enrolled for the study. Spirometric recordings were done at three different time points. First: 5-10 days before the start of Ramadan (Pre-Ramadan); second: within 10 days of the beginning of Ramadan fasting (Ramadan); third: within 7 days of the end of Ramadan (Post-Ramadan). There were no statistically significant differences between the three phases with respect to tidal volume (TV), inspiratory reserve volume (IRV), expiratory reserve volume (ERV), forced vital capacity (FVC), forced expiratory volume in 1 sec (FEV1), FEV1/FVC, peak expiratory flow rate (PEFR) and forced expiratory flow 25% to 75% (FEF25-27). To conclude, Ramadan fasting does not have any significant effect on pulmonary function tests as assessed by spirometry. Hence, the diagnosis and prognosis of a respiratory disorder made on spirometry findings are reliable and need no error correction if an individual is fasting.
