Kidney Health & CKD: Small Numbers That Deserve Attention

Kidney disease may remain silent until advanced. Blood pressure, diabetes, creatinine and urine protein are important clues.

Kidney disease can be silent

Chronic kidney disease may not cause symptoms in its early stages. People with diabetes, hypertension, older age or previous kidney injury may need periodic assessment.

Useful tests

Serum creatinine with estimated filtration rate and urine testing for protein or albumin are commonly used. One abnormal result does not always establish chronic disease; persistence and clinical context matter.

Protecting kidney function

Good blood-pressure and diabetes control, avoiding unnecessary painkillers and unregulated remedies, reviewing medicines during dehydration or acute illness, and maintaining appropriate hydration can help protect kidney function.

When to seek assessment

Swelling, reduced urine, blood in urine, persistent vomiting, severe weakness, breathlessness or rapidly worsening kidney blood tests require medical review.

Emergency symptoms: If there is severe chest pain, major breathing difficulty, new weakness/speech difficulty, loss of consciousness, seizure, severe bleeding or another rapidly life-threatening problem, seek emergency medical care rather than waiting for an online response.
