What is chronic kidney disease? A guide to understanding it
A diagnosis of chronic kidney disease is frightening, mostly because of what goes unexplained. Here it is in plain terms: what it is, its stages, and why food matters so much.
What do the kidneys do?
They filter the blood, remove waste and excess fluid, and balance minerals such as potassium, phosphorus and sodium. When they fail, these build up and harm the body.
The 5 stages
- Stages 1-2: mild damage, little or no restriction.
- Stage 3: potassium and phosphorus control begins.
- Stage 4: strict control to slow progression.
- Stage 5: kidney failure; dialysis is usually needed.
Why nutrition is central
Every meal can either help weakened kidneys or overload them. A suitable diet, alongside medical treatment, is one of the most powerful tools to slow progression and live better.
Your exact limits depend on your stage and your nephrologist. This guide is a starting point, not a replacement for medical advice.
