Ramadan is a time of spiritual reflection and discipline, but long hours without water can raise health concerns — especially for people prone to kidney stones. If you have a history of stones or kidney pain, you may wonder: Is fasting safe, and how can I prevent stone formation during Ramadan?
The experienced urologists at Medeor Hospital, Dubai emphasize that dehydration is one of the biggest risk factors for kidney stones. With proper precautions, many people can fast safely — but those at higher risk should seek medical guidance before Ramadan begins.
Why Kidney Stone Risk Increases During Fasting
Kidney stones form when minerals and salts crystallize in concentrated urine. During fasting:
- Fluid intake drops significantly
- Urine becomes more concentrated
- Mineral deposits accumulate more easily
- Reduced urination allows crystals to grow
Hot weather, physical activity, and caffeine consumption can worsen dehydration, increasing the likelihood of stone formation or triggering painful attacks.
Who is at Higher Risk?
You may be more vulnerable during Ramadan if you:
- Have a history of kidney stones
- Live in hot climates
- Sweat heavily due to work or exercise
- Have chronic dehydration
- Consume high-salt or high-protein diets
- Have metabolic conditions (e.g., gout, obesity)
- Have a family history of stones
Men are generally more affected than women, but anyone can develop stones.
Signs of Kidney Stones to Watch For
Seek medical attention if you experience:
- Severe pain in the back or side
- Pain radiating to the lower abdomen or groin
- Burning during urination
- Blood in urine
- Nausea or vomiting
- Frequent urge to urinate
These symptoms can escalate quickly and may require urgent care.
How to Protect Yourself While Fasting
Prioritize Hydration Between Iftar and Suhoor
The most effective prevention strategy is adequate fluid intake.
Aim for at least 2–3 liters of water between sunset and dawn unless otherwise advised by your doctor.
Tips:
- Drink water gradually, not all at once
- Start with water at Iftar before other foods
- Continue hydrating until bedtime
- Drink again at Suhoor
Avoid relying on sugary drinks or caffeine, which can increase urine loss.
Limit Salt and Processed Foods
High sodium intake increases calcium excretion in urine, promoting stone formation.
Reduce:
- Pickles and salted snacks
- Processed foods
- Fast food
- Instant meals
Choose fresh, home-cooked meals instead.
Moderate Animal Protein Intake
Excessive red meat, poultry, and seafood can increase uric acid levels and stone risk.
Balance your meals with:
- Vegetables
- Fruits
- Whole grains
- Plant-based proteins
Include Stone-Protective Foods
Certain foods may help reduce stone risk:
- Citrus fruits (lemons, oranges) — increase citrate, which prevents stones
- Calcium-rich foods (milk, yogurt) — bind oxalate in the gut
- Potassium-rich foods (bananas, dates)
Avoid excessive oxalate-rich foods if prone to calcium oxalate stones, such as spinach, nuts, and chocolate.
Maintain Regular Urination
Do not ignore the urge to urinate during non-fasting hours. Frequent urination helps flush out crystals before they grow.
Avoid Excessive Heat and Dehydrating Activities
Limit strenuous outdoor activity during fasting hours, especially in hot climates like the UAE. If unavoidable, increase hydration after sunset.
Continue Prescribed Medications
If your urologist has prescribed medications to prevent stones, take them exactly as advised during permitted hours.
When Fasting May Not Be Safe
Medeor’s urologists may advise against fasting if you have:
- Recurrent or large kidney stones
- Chronic kidney disease
- Recent kidney surgery
- Frequent urinary infections
- Severe dehydration risk
- Obstruction in the urinary tract
Individual medical evaluation is essential.
