Key Takeaways
- Dubai's heat increases kidney stone risk, so aim for 2.5-3.5 liters of water daily to produce light-colored urine
- 10% of UAE residents will experience a kidney stone; 50% will have another within 5-10 years without prevention
- Diabetes and high blood pressure are the leading causes of chronic kidney disease, so get screened annually
- Early kidney disease has no symptoms; a simple blood and urine test can detect problems before damage is severe
- Regular NSAID use (ibuprofen) can harm kidneys, especially with dehydration. Use paracetamol when possible
- Dietary calcium is protective; don't reduce dairy unless advised. Instead, reduce salt, sugar, and excess protein
Your kidneys filter about 180 liters of blood every day, removing waste, balancing fluids, and regulating blood pressure. Yet most people never think about kidney health until something goes wrong. In Dubai's extreme heat, where dehydration is common and kidney stones are frequent, understanding how to protect these vital organs is essential.
Why Kidney Problems Are So Common in the UAE
The UAE has some of the highest rates of kidney stones in the world, and chronic kidney disease is increasingly prevalent. Several factors contribute:
- Extreme heat: Even with AC, you lose more fluid than you realize
- Chronic dehydration: Many people simply don't drink enough water
- Diabetes prevalence: The UAE has one of the world's highest diabetes rates, and diabetes is the #1 cause of kidney failure
- High blood pressure: Often undiagnosed and untreated, causing silent kidney damage
- Dietary factors: High salt, high protein, sugary drinks
- Medication overuse: Regular painkiller use without hydration
Key Fact
Approximately 1 in 10 people in the UAE will experience a kidney stone during their lifetime, with rates significantly higher than global averages due to climate and dietary factors

Kidney Stones: Prevention in Dubai's Climate
Kidney stones form when minerals in concentrated urine crystallize into solid masses. The pain of passing a stone is often described as worse than childbirth. The good news: most stones are preventable.
Hydration: The Single Most Important Factor
In Dubai's climate, you need to drink more than you think:
- Target: 2.5-3.5 liters of fluids daily
- Goal: Urine should be light yellow, almost clear
- Timing: Drink throughout the day, not all at once
- Summer: Increase intake, especially if outdoors or exercising
- Tip: Keep a water bottle at your desk and set reminders
Dietary Changes That Reduce Stone Risk
- Reduce salt: High sodium increases calcium in urine; avoid processed foods
- Moderate protein: Excessive animal protein increases stone risk
- Add citrus: Lemon, lime, and orange contain citrate, which prevents stone formation
- Eat normal calcium: Dietary calcium actually binds oxalate and reduces stone risk
- Limit oxalates: If prone to stones, moderate spinach, rhubarb, beets, and nuts
- Avoid sugary drinks: Fructose in sodas increases stone risk
Surprising Fact About Dairy
Many people with kidney stones avoid dairy, thinking calcium causes stones. Actually, dietary calcium reduces kidney stone risk by binding to oxalate in the gut. Don't restrict dairy unless specifically advised by your doctor. Calcium supplements, however, may increase risk if not taken with meals.
Chronic Kidney Disease: The Silent Threat
Chronic kidney disease (CKD) affects millions of people in the UAE, and most don't know they have it until the disease is advanced. By the time symptoms appear, significant kidney function has already been lost.
Who Is at Risk for CKD?
- Diabetes: The leading cause of kidney failure worldwide
- High blood pressure: Damages kidney blood vessels over time
- Family history: Kidney disease often runs in families
- Age over 60: Kidney function naturally declines with age
- Obesity: Increases risk of diabetes and hypertension
- Smoking: Accelerates kidney damage
- Frequent NSAID use: Regular painkiller use can harm kidneys
Key Fact
Diabetes and high blood pressure together account for about 70% of all chronic kidney disease cases. Controlling these conditions is the most effective way to protect your kidneys

Warning Signs of Kidney Disease
Early CKD often has no symptoms. When symptoms do appear, they may include:
- Fatigue and weakness (from anemia)
- Swelling in ankles, feet, hands, or face
- Foamy or bubbly urine (protein in urine)
- Blood in urine (pink or cola-colored)
- Increased urination, especially at night
- Decreased urine output
- Persistent itching
- Loss of appetite, nausea
- Difficulty concentrating
- High blood pressure that's hard to control
Kidney Function Testing: What to Expect
Kidney function is assessed with simple blood and urine tests. Here's what they measure:
Blood Tests
- Creatinine: A waste product filtered by kidneys; high levels suggest reduced function
- eGFR: Estimated glomerular filtration rate, the best overall measure of kidney function
- BUN: Blood urea nitrogen, another waste product
- Electrolytes: Sodium, potassium, calcium (kidneys balance these)
Urine Tests
- Albumin/protein: Protein in urine is an early sign of kidney damage
- Blood: Microscopic blood may indicate kidney or urinary tract problems
- Urine albumin-to-creatinine ratio (UACR): Detects early diabetic kidney disease
Kidney Test Costs in Dubai (2025)
| Test | Price Range (AED) |
|---|---|
| Basic Kidney Panel (Creatinine, BUN) | 100 - 200 |
| Comprehensive Renal Panel | 200 - 400 |
| Urine Albumin (Microalbumin) | 80 - 150 |
| Kidney Ultrasound | 400 - 700 |
| Nephrology Consultation | 400 - 600 |
Protecting Your Kidneys: Practical Steps
1. Stay Hydrated
This can't be overstated in Dubai. Carry water with you, set phone reminders, and monitor your urine color.
2. Control Diabetes and Blood Pressure
If you have diabetes, keep your HbA1c below 7%. If you have hypertension, aim for blood pressure below 130/80. These two conditions cause most kidney disease, and controlling them preserves kidney function.
3. Use Painkillers Wisely
NSAIDs (ibuprofen, naproxen, diclofenac) can damage kidneys with regular use, especially if you're dehydrated. For chronic pain, discuss alternatives with your doctor. Paracetamol is generally safer for kidneys.
4. Don't Smoke
Smoking accelerates kidney damage and increases the risk of kidney cancer. Quitting protects not just your lungs but your kidneys too.
5. Get Regular Checkups
If you have risk factors (diabetes, hypertension, family history, age over 60), get annual kidney function tests. Early detection allows treatment before irreversible damage occurs.
When to See a Nephrologist
You should see a kidney specialist (nephrologist) if you have:
- eGFR below 60 (moderate kidney disease)
- Protein in your urine persistently
- Blood in urine after other causes ruled out
- Recurrent kidney stones
- Difficult-to-control blood pressure
- Family history of kidney failure
- Rapid decline in kidney function
