Kidney Health During Ramadan: Why Drinking Water Is a Crucial Factor

Introduction: When Fasting Becomes a Silent Test for Kidney Health

The holy month of Ramadan is a great spiritual opportunity, but at the same time, it imposes precise physiological challenges on the body, primarily dealing with long periods without drinking water. While many people focus on monitoring their energy levels or feelings of hunger, the kidneys work silently throughout the fasting hours to maintain fluid balance and cleanse the blood of toxins. This raises a crucial question: does the body—particularly the kidneys—receive enough water during Ramadan? The answer is not simple, yet it is vital, because water is not just a beverage, but an essential element for the kidneys to function efficiently, especially in an environment of long fasting hours and high temperatures in many Arab countries.

First: The Vital Role of the Kidneys in the Body

The Kidneys… The Primary Purification System

The kidneys are not just organs responsible for producing urine, but among the most important purification systems in the body, continuously filtering the blood of toxins and metabolic waste, regulating levels of minerals such as sodium and potassium, and maintaining fluid balance. The kidneys also play a central role in regulating blood pressure by controlling the amount of fluids and salts, and contribute to producing hormones necessary for red blood cell formation, making their health crucial for overall bodily well-being, especially during long fasting hours.

Water: The Fuel for Kidney Function

All kidney functions directly depend on an adequate supply of water in the body, as water helps improve blood flow to the kidneys and enables efficient filtration. When water intake is insufficient, blood volume reaching the kidneys decreases, filtration efficiency drops, and urine becomes more concentrated, leading to the accumulation of salts and waste in the urinary system. With repeated water deficiency day after day during Ramadan, the kidneys begin to experience stress, increasing the likelihood of health issues such as dehydration, infections, or kidney stone formation.

Second: What Happens to the Kidneys During Fasting?

Smart Adaptation… But With Limits

During fasting hours, the body employs smart adaptation mechanisms to preserve fluids by reducing urine output, retaining sodium and water, and increasing urine concentration to minimize fluid loss. While these mechanisms temporarily help the body cope with the lack of drinking, they are limited in effectiveness, and if fluids are not adequately replenished after Iftar, the kidneys experience continuous stress due to increased waste and salt concentration, which may negatively affect their efficiency with repeated fasting.

The Effect of Long Fasting Hours

The longer the fasting hours, the greater the fluid loss through respiration and sweating, and the higher the urine concentration, which increases the strain on the kidneys, making them operate under less optimal conditions. This effect is particularly significant in hot climates, during physical activity, or with excessive consumption of caffeinated beverages or salty foods after Iftar, all of which increase the likelihood of dehydration and place additional pressure on kidney function during Ramadan.

Third: Dehydration… The Hidden Enemy of Kidney Health During Ramadan

What Is Dehydration?

Dehydration is not just extreme thirst; it is a physiological condition that occurs when the body loses more fluids than it receives, leading to an imbalance of water within cells and tissues. During Ramadan, fasting individuals may gradually become dehydrated without realizing it, especially with long fasting hours and inadequate fluid intake between Iftar and Suhoor, which directly affects the efficiency of vital organs, primarily the kidneys.

How Dehydration Harms the Kidneys

When dehydration occurs, blood volume reaching the kidneys decreases, impairing their ability to filter toxins and waste effectively, increasing urine concentration and salt levels. This creates an environment conducive to kidney stone formation and may irritate the urinary tract, raising the risk of infections, especially if water intake remains insufficient for several consecutive days during Ramadan.

Warning Signs Not to Ignore

Several signs indicate insufficient fluid intake, such as reduced urination, dark yellow urine, a strong odor, fatigue, and headaches, sometimes accompanied by muscle cramps due to electrolyte imbalance. These symptoms are clear messages from the body indicating an urgent need for water and should be addressed seriously to avoid health complications, particularly those affecting kidney health.

Fourth: Why Drinking Water Is Crucial for Kidney Health in Ramadan

Helps Flush Out Toxins

Drinking an adequate amount of water helps the kidneys perform their primary role of eliminating toxins and waste efficiently by increasing urine flow and reducing the concentration of harmful substances, preventing waste accumulation. Consistent water intake between Iftar and Suhoor makes the purification process smoother and reduces stress on the kidneys despite long fasting hours.

Reduces the Risk of Kidney Stones

Insufficient water intake is one of the main causes of kidney stone formation, especially during Ramadan, as low fluid levels increase the concentration of salts in urine. Drinking water regularly dilutes these salts, reducing the likelihood of calcium and oxalate deposits and helping protect the kidneys from stone formation and related complications.

Protects Against Urinary Tract Infections

Water naturally cleanses the urinary tract by increasing urination, which helps flush out bacteria and prevents their growth in the urinary system. Maintaining adequate hydration during Ramadan reduces the likelihood of urinary tract infections and alleviates uncomfortable symptoms such as burning sensations or discomfort during urination.

Supports Healthy Blood Pressure

Since the kidneys play a key role in regulating blood pressure, sufficient water intake helps reduce the stress on them and allows them to function efficiently. Proper hydration also supports stable blood pressure during fasting, minimizing fluctuations that may result from dehydration or fluid imbalance.

Fifth: Common Mistakes in Drinking Water During Ramadan

Drinking Large Quantities at Once

Some people drink large amounts of water at once after Iftar, thinking it compensates for the fasting hours, but this approach does not benefit the kidneys properly, as the body cannot absorb the large quantity efficiently in a short time. It may also cause fullness or stomach discomfort, while the kidneys quickly eliminate a large portion of the water without optimal benefit, depriving the body of gradual and sustained hydration.

Relying on Juices Instead of Water

Some rely on juices as the main source of fluids during Ramadan, but this is not a healthy substitute for water, as juices often contain high amounts of sugar and may increase the burden on the kidneys rather than supporting them. Juices do not provide the pure hydration the body needs and may cause fluid imbalance if relied upon excessively while neglecting proper water intake.

Neglecting Water After Suhoor

Neglecting to drink water after Suhoor is a common mistake during Ramadan, as it starts the fasting period with a fluid deficit, causing early dehydration and continuous stress on the kidneys throughout the day. This neglect reduces the body’s ability to cope with fasting and increases the likelihood of fatigue, headaches, and impaired kidney function, especially during long fasting hours.

Sixth: The Ideal Amount of Water in Ramadan

Is There a Fixed Number?

There is no single fixed number for water intake during Ramadan, as the body’s needs vary according to age, weight, activity level, and temperature, but on average most people need around 2 to 3 liters of water per day. This quantity should be distributed evenly between Iftar and Suhoor to ensure proper hydration and support kidney health.

Smart Water Distribution

Intelligently distributing water intake during fasting hours is essential for maintaining kidney health. It is recommended to start Iftar with two glasses of water, then continue drinking a glass every hour or two, and ensure an adequate amount before Suhoor, helping the body retain fluids and reduce the risk of dehydration during fasting hours.

Urine Color as an Important Indicator

Urine color is one of the simplest and clearest indicators of hydration status. Light-colored urine indicates adequate water intake and good hydration, while dark-colored urine signals fluid deficiency and the body’s urgent need to increase water consumption, serving as an early warning not to be ignored during Ramadan.

Seventh: Groups Most in Need of Focused Hydration

Certain groups are more vulnerable to the effects of dehydration during Ramadan, including kidney patients, individuals with high blood pressure or diabetes, as well as the elderly and those who work in hot environments or perform significant physical activity. These groups’ bodily functions are affected more quickly by fluid loss, making water intake a health priority that cannot be neglected, with careful distribution between Iftar and Suhoor to maintain fluid balance and support kidney health throughout fasting.

Eighth: The Role of Suhoor in Protecting the Kidneys

A balanced Suhoor meal with water is essential to reduce fluid loss during fasting hours, helping maintain kidney function and reduce feelings of fatigue during the day. It is preferable to drink water gradually during Suhoor rather than consuming it all at once, avoid salty foods that increase thirst and dehydration, and include water-rich vegetables in the meal, which supports hydration and enables the kidneys to function efficiently throughout Ramadan.

Ninth: Can Other Drinks Replace Water?

Coffee and Tea

Coffee and tea are diuretic beverages and cannot be relied upon to compensate for water loss in the body. Excessive consumption during Ramadan may increase dehydration and stress the kidneys, so they should be consumed in moderation alongside sufficient pure water intake between Iftar and Suhoor to maintain hydration and kidney health.

Herbal Drinks

Some herbal drinks are beneficial for health but cannot replace water or be relied upon as the main source of fluids. It is recommended to include them as part of a balanced diet along with adequate water intake to ensure proper hydration and support kidney function efficiently during long fasting hours.

Conclusion: Water… The First Line of Defense for Kidney Health During Ramadan

Kidney health during Ramadan depends not only on abstaining from food but primarily on smart management of water intake in a regular and distributed manner between Iftar and Suhoor. Water serves as a natural means to cleanse the body of toxins and as a source of kidney protection while supporting fluid balance. By adhering to this daily habit, a fasting individual can maintain active kidneys and stable bodily functions, making fasting healthy and safe while reducing the risks of dehydration and potential complications. Ordering water from the Abar app is an ideal choice to ensure efficient and high-quality hydration, providing pure and safe water that supports kidney health during long fasting hours.
