Hydration status and liver function of young men before and after Ramadan fasting

Abstract

The objective of this study was to identify and analyse the hydration status and liver function of young men before and during Ramadan fasting (RF). The study design was a prospective cohort into 1 st period (one week before fasting) and 2 nd period (the last ten days of fasting). The subjects were 18 healthy young men (19-30 years old). Data on dietary intake were collected using food record 3x24h, body composition were collected using bioelectrical impedance analyser (BIA), hydration status, and liver function data were measured trough urine and blood sample. This study showed significant differences in body weight, fat body mass, body mass index (BMI), body water, intake of energy, protein, fat, carbohydrate, and water, hydration status (serum osmolality and urine density), and liver function (SGOT and SGPT levels) before and during RF (p<0.05). There were significant correlation between fasting status and SGPT levels (p<0.05). The study concluded that Ramadan fasting has a positive effect to control body weight and improve liver function measured by SGOT and SGPT levels.

Effects of Time-Restricted Feeding during Ramadan on Dietary Intake, Body Composition and Metabolic Outcomes

“…Given that water intake is highly restricted within the period of Ramadan, in the first phase of this review, we will focus on the impact of fluid restriction on the levels of dehydration. Studies indicate that Ramadan fasting results in lower water intake during the month [ 10 , 11 ]. This potentially causes an alteration in kidney function, whereby water is reabsorbed by the body instead of being excreted in order to maintain fluid balance [ 11 ].…”

“…Studies indicate that Ramadan fasting results in lower water intake during the month [ 10 , 11 ]. This potentially causes an alteration in kidney function, whereby water is reabsorbed by the body instead of being excreted in order to maintain fluid balance [ 11 ]. As such, there is effective water conservation during Ramadan fasting, by maximising urinary concentration as well as decreasing obligatory urine output [ 1 , 12 ].…”

“…Hydration status is commonly measured by serum osmolality and urine specific gravity [ 11 ]. In a study by Ibrahim et al of 18 healthy young men during Ramadan fasting, it was found that serum osmolality levels were within the normal range, as the homeostatic mechanisms kept serum osmolality at normal levels [ 11 ].…”

Hosseini et al, Mustafa et al and Dikme and Fasting also showed that there was no significant difference in serum osmolality before and during Ramadan fasting [ 12 , 14 , 15 ].…”

The Impact of Dehydration in the Third Trimesters on Pregnancy Outcome-Infant Birth Weight and Length

“…Meanwhile, the mothers in NG (normal) were in the sufficient category. Hypo-hydration amongst Indonesian young men and women (18-30 years) is not uncommon, despite the homeostatic response to changes in osmolality which then activate the osmoreceptor to increase ADH level to stimulate thirst (Ibrahim et al 2018), a study found the majority of them were in the deficient category (81.9%) (Febriyani et al 2012).…”
