How can I protect kidney function, and is drinking lots of water enough?
Kidney protection depends on blood-pressure and diabetes control, avoiding smoking and unsafe medicine use, and suitable nutrition and fluids. Large amounts of water do not guarantee protection and can harm people with fluid restrictions. Higher-risk people may need tests without symptoms.

Which tests should you discuss?
Blood-based kidney function assessment and urine albumin may be appropriate, especially with diabetes, hypertension or family history. Results and risk determine frequency; early disease may cause no pain or visible urine change.
Watch painkillers and herbal products
NSAIDs such as ibuprofen can harm kidneys in some situations, especially with dehydration or existing disease. Ask before repeated use, and do not independently stop prescribed blood-pressure treatment. Kidney cleanses do not replace care.
Habits and an individual plan
Reduce salt and choose suitable activity and weight goals. Avoid unnecessary protein or potassium restriction. New reduced urine, rapid swelling or breathlessness needs urgent assessment, not forced water intake.
