World Kidney Day: Kidney Health, Risk Factors and When to Get Tested
World Kidney Day, observed on the second Thursday of March, encourages people to understand kidney health and seek appropriate care. Its message matters throughout the year: kidney problems do not always cause pain, and feeling well does not guarantee normal kidney function. Annual themes change; this page provides everyday guidance rather than presenting an old campaign as the latest news.
When symptoms need urgent attention
A sudden marked fall in urine, fever with back or side pain, or persistent vomiting needs urgent medical assessment. Severe breathlessness, confusion, collapse or inability to pass urine needs immediate emergency care. Do not wait for a routine consultation or try to correct these symptoms by forcing extra water.
What do your kidneys do?
Your kidneys remove waste and excess water from blood to make urine. They also help balance salts and acidity, regulate blood pressure and produce hormones involved in red blood cell production and bone health. Kidney disease can affect these functions even before noticeable symptoms appear.
Who should discuss kidney testing?
Diabetes, high blood pressure, heart disease and a family history of kidney failure are important reasons to discuss testing. People with diabetes generally need a kidney check every year; the interval for other risk factors depends on the clinician’s assessment. Previous acute kidney injury and known urinary problems should also be mentioned during a consultation.
Blood and urine tests answer different questions
| Assessment | What it helps evaluate |
|---|---|
| Creatinine and estimated GFR (eGFR) | A blood test helps estimate how effectively the kidneys filter blood. |
| Urine albumin-to-creatinine ratio (UACR) | Checks for albumin leakage, which can indicate kidney damage even when filtration is preserved. |
| Blood pressure and clinical review | Helps assess risk, medicines and possible causes of abnormal results. |
| Ultrasound or other investigations | May be needed for suspected stones, obstruction or structural problems; these are not required for everyone. |
One abnormal test does not automatically establish chronic kidney disease. Chronic abnormalities generally persist for more than three months, while a sudden deterioration may be acute kidney injury and need prompt care. Follow the doctor’s advice about repeat testing; do not delay urgent assessment simply to wait three months.
Different kidney and urinary problems need different care
- Chronic kidney disease: Persistent kidney damage or reduced function. Early stages may be symptom-free; later symptoms can include tiredness, swelling or changes in urination.
- Acute kidney injury: A sudden decline in function associated with problems such as severe illness, dehydration, medicines or urinary blockage. It can occur without obvious symptoms.
- Kidney stones: Hard deposits that may cause severe side pain, nausea or blood in urine. Fever with possible obstruction needs urgent assessment.
- Urinary infection: Burning and frequent urination may arise from a lower urinary infection. Fever, flank pain or vomiting may suggest kidney involvement.
- Inherited conditions: Conditions such as polycystic kidney disease may require family-history assessment and specialist follow-up.
Symptoms overlap with other illnesses. A clinician needs your history, examination and relevant tests to identify the cause. Early treatment can help protect remaining function, but recovery and progression depend on the condition.
Practical habits that support kidney health
- Manage diabetes and blood pressure with the treatment and follow-up agreed with your clinician.
- Choose balanced meals and reduce excess salt from packaged snacks, pickles and processed foods. A diagnosed kidney condition may require an individual diet plan.
- Stay active within your ability and avoid tobacco.
- Drink fluids appropriate to your needs. Hyderabad heat and activity can increase losses, but people with fluid restrictions should follow their prescribed limit.
- Ask before using painkillers such as ibuprofen or diclofenac, especially with dehydration or kidney disease. Do not stop prescribed medicines without advice.
- Avoid unverified kidney-cleansing products and disclose herbal remedies, supplements and gym products at appointments.
There is no universal eight-to-ten-glass target or detox drink that prevents every kidney problem. Potassium, protein and fluid restrictions should be based on your diagnosis and test results.
Prepare for your appointment
Bring previous creatinine/eGFR and urine reports, scan results, a medicine and supplement list, and any home blood pressure or glucose readings. Note changes in urine, swelling, recent fever, vomiting or diarrhoea. Ask what the results mean, whether repeat tests are needed and which symptoms should prompt urgent care.
Urology consultations at My Health Hospitals
For stones, urinary obstruction and other urological concerns, contact the appropriate branch. Persistent loss of kidney function or protein leakage may require a nephrologist; these urology consultations do not replace medical kidney specialist care.

Frequently Asked Questions
When is World Kidney Day observed?
World Kidney Day is observed on the second Thursday of March. Annual campaign themes change; use the official campaign website for the relevant year.
Can kidney disease develop without symptoms?
Yes. Early chronic kidney disease often causes no obvious symptoms. People with risk factors should discuss blood and urine testing rather than waiting for pain.
Which tests check kidney health?
A blood creatinine test is used to estimate filtration through eGFR, and a urine albumin-to-creatinine ratio checks for albumin leakage. Other tests depend on the clinical assessment.
Does one abnormal result confirm chronic kidney disease?
No. Results need clinical interpretation, comparison with earlier tests and sometimes repeat testing. Chronic kidney disease generally involves abnormalities lasting more than three months; a sudden change may need urgent assessment.
Should everyone drink eight to ten glasses of water?
No single amount suits everyone. Needs vary with weather, activity and health. Follow any prescribed fluid restriction, especially with kidney or heart disease.
Do kidney stones and chronic kidney disease mean the same thing?
No. Stones are solid deposits in the urinary tract; chronic kidney disease concerns persistent kidney damage or reduced function. A stone causing blockage or infection can still threaten kidney function.
When should I seek urgent care?
Seek urgent assessment for markedly reduced urine, fever with flank pain, persistent vomiting or worsening illness. Severe breathlessness, confusion, collapse or inability to pass urine require immediate emergency care.
Should I see a urologist or a nephrologist?
Urologists assess stones, urinary obstruction and surgical urinary problems. Nephrologists manage medical kidney disease, persistent protein leakage and reduced kidney function. A physician can help arrange the appropriate referral.
