Kidney Health - Patient Guide

Kidney Health (CKD)

Your kidneys are working below normal. Most people stay stable for years — these habits keep it that way.

What is it?

Your kidneys filter waste and extra fluid from your blood. Chronic kidney disease (CKD) means they are working below normal — we find it with a blood test (eGFR) and a urine test for protein, usually before you feel anything. Most people with CKD never need dialysis, especially when blood pressure and blood sugar stay controlled.

What can I do?

  • Control blood pressure — nothing protects kidneys more. Take your BP medicines every day.
  • Control blood sugar if you have diabetes.
  • Keep taking kidney-protective medicines we prescribe (like an ACE/ARB or an SGLT2 pill) — they slow CKD down even when you feel no different.
  • Skip NSAIDs (ibuprofen, naproxen) — they are the most common avoidable kidney insult.
  • Eat less salt and less processed food.
  • Tell every doctor, dentist, and pharmacist about your kidneys before new medicines, supplements, or scans with contrast dye.
  • When you are sick and can't keep fluids down, ask us which medicines to pause until you recover — some become harmful when you're dehydrated.

What can I expect?

Lab checks once or twice a year (more if things change). Know your eGFR number and track it over time like you would a blood pressure.

When should I call?

  • New swelling in your legs or around your eyes.
  • A big change in how much you urinate.
  • Before starting any new over-the-counter medicine or supplement.
  • Go to the ER for little or no urine output, or swelling with shortness of breath.
