Physiology of Ramadan Fasting Introduction
During Ramadan, fasting Muslims tend to avoid consulting their doctors. It is consequently no longer unexpected that invasive research was hard to conduct, paramount to a relative lack of direct proof concerning the physiological results of Ramadan fasting. Much of the perception received has been extrapolated from research concerning topics that fasted for more than forty-eight hours.
However,
Over the last few years, a few research studies have been performed on glucose metabolism, lipid profiles, circadian rhythms, sleep, and hormone body structure factors throughout Ramadan.
In fasting Muslims, the onset of Ramadan heralds a surprising shift in mealtimes, as correctly as in sleep and wakefulness styles. Figure 1 describes the familiar sound asleep/consuming sample of Muslims in many nations throughout Ramadan and non-Ramadan. However, many Muslims can be comprehensively conscious of the night and numb after sunrise in different countries.
As no meals or drink is taken throughout daylight hours, the time among food throughout Ramadan is longer than in other months. This has crucial implications for body structure, resulting in adjustments in the rhythm and significance of fluctuations in numerous homeostatic and endocrine processes. The length of the short influences the physiological adjustments that occur; that is of specific relevance. Ramadan falls throughout longer summertime season days, with better latitudes experiencing the maximum daylight hours.
Ramadan body structure – fasting inside the wholesome individual.
Changes in sound asleep styles and circadian rhythms throughout Ramadan Sleeping styles are frequently altered throughout Ramadan. Sleep is typically damaged before sunrise, which allows Muslims to consume before fasting begins (suhoor). Man will go back to sleep afterward and wake for a 2d time to start the day. Some fasting Muslims may also sleep inside in the afternoon. Following the night meal (iftar), many will live wide conscious till midnight or later.
The effect of Ramadan on sleep includes reduced available sleep time, not on-time sleep, reduced sleep length time, reduced fast eye movement (REM) sleep length, a reduced share of REM sleep, and a multiplied share of non-REM sleep. Sleep deprivation has been associated with reduced glucose tolerance, and the correlation between sound sleep length and insulin resistance has been a topic of renewed scientific interest. However, the relevance of this to fasting throughout Ramadan isn’t known.
3 Effects of fasting on glucose homeostasis in wholesome individuals
Extended glucose degrees inside the blood after ingesting stimulate insulin secretion in wholesome individuals, which triggers the liver and muscle groups to shop glucose as glycogen. Liver glycogen can offer sufficient glucose for the mind and peripheral tissues for around 12 hours. When glycogen shops are depleted, ed and insulin degrees are low; fatty acids are launched from adipocytes and oxidized to generate ketones, which may be used as a gas through many organs, retaining glucose for the mind and erythrocytes.

In a healthy individual, fasting causes the discharge of glucose from glycogen stores (glycogenolysis) and the formation of glucose from non-carbohydrate substrates (gluconeogenesis) 34. During Ramadan, every fasting length is regularly more than 12 hours. Therefore, it can be considered a nation of intermittent glycogen depletion and repletion.
In practice, most people who take their first meal at sunrise are in a state of glycogen depletion through the past-due afternoon, at which point ketogenesis occurs. The omission of suhoor ends the lack of glycogen stores and ketosis plenty in advance within the fasting day.
- Although fasting blood glucose degrees have been proven to lower during Ramadan, the latest non-stop glucose monitoring (CGM) looks at discovering an excellent blood glucose balance in seven wholesome topics during fasting hours. It does not show extended time spent in hypoglycemia compared to non-Ramadan periods. This is notwithstanding reviews of symbolized insulin resistance in the course of Ramadan. A modest upward push in interstitial glucose (and thus blood glucose) becomes seen at iftar, which remained inside daily limits.
