O believers! Fasting is prescribed for you—as it was for those before you1—so perhaps you will become mindful ˹of Allah˺. ˹Fast a˺ prescribed number of days.1 But whoever of you is ill or on a journey, then ˹let them fast˺ an equal number of days ˹after Ramaḍân˺. For those who can only fast with extreme difficulty,2 compensation can be made by feeding a needy person ˹for every day not fasted˺. But whoever volunteers to give more, it is better for them. And to fast is better for you, if only you knew. Ramaḍân is the month in which the Quran was revealed as a guide for humanity with clear proofs of guidance and the decisive authority. So whoever is present this month, let them fast. But whoever is ill or on a journey, then ˹let them fast˺ an equal number of days ˹after Ramaḍân˺. Allah intends ease for you, not hardship, so that you may complete the prescribed period and proclaim the greatness of Allah for guiding you, and perhaps you will be grateful.
Can I Fast in Ramadan If I Have Kidney Stones?
Fasting during Ramadan is an important spiritual practice for millions of Muslims worldwide. However, if you have kidney stones, you may be concerned about whether fasting is safe for you. Kidney stones develop when minerals and salts crystallize in the kidneys, often due to dehydration or dietary factors. Since fasting involves long hours without water, it is crucial to understand the risks and precautions before deciding whether to fast.
Is It Safe to Fast with Kidney Stones?
The safety of fasting with kidney stones depends on several factors, including the size of the stones, your medical history, and how well your kidneys are functioning. Here’s what you need to consider:
Dehydration Risk: Fasting reduces fluid intake, which may lead to dehydration and increase the risk of stone formation or aggravate existing stones.
Stone Size and Type: Smaller stones may pass naturally, but larger stones could cause pain or block the urinary tract, which may worsen without sufficient hydration.
Kidney Function: If your kidneys are already compromised, fasting may put additional strain on them.
Doctor’s Advice: Consulting a healthcare professional is essential before making a decision.
How to Reduce Risks While Fasting with Kidney Stones
If your doctor approves fasting, you can take precautions to minimize risks and keep your kidneys healthy during Ramadan.
1. Stay Hydrated During Non-Fasting Hours
Drink at least 8–10 glasses of water between Iftar and Suhoor to help flush out toxins and prevent stone formation. Avoid caffeinated drinks like tea and coffee, which can lead to dehydration.
2. Monitor Your Diet
Certain foods can trigger kidney stones. During Iftar and Suhoor, limit:
Salty and processed foods that increase calcium buildup in the kidneys.
Oxalate-rich foods like spinach, chocolate, and nuts (for those prone to calcium oxalate stones).
Sugary drinks that may increase the risk of kidney stones.
Excessive animal protein (red meat, poultry), which can contribute to uric acid stones.
Instead, eat foods that promote kidney health, such as:
Citrus fruits (lemons, oranges) to prevent stone formation.
Whole grains, vegetables, and dairy in moderation for balanced nutrition.
3. Break Your Fast Gently
Start with water and dates and avoid heavy, greasy, or salty meals that can burden the kidneys. Eating smaller, frequent portions rather than one large meal can also help digestion.
4. Reduce Sodium Intake
High sodium levels can contribute to stone formation. Choose fresh, home-cooked meals over processed or fast foods, which tend to be high in salt.
5. Listen to Your Body
If you experience severe pain, nausea, vomiting, or difficulty urinating while fasting, break your fast immediately and seek medical help.
Conclusion
Fasting with kidney stones can be risky, especially if you are prone to dehydration or have a history of severe stones. However, with proper hydration, a balanced diet, and medical guidance, some individuals may be able to fast safely. If you have kidney stones, always consult your doctor before deciding to fast. Your health should come first, and Islam allows exemptions from fasting for those with medical conditions.
