Basic Potassium Guidelines For People With
Renal Disease
Why Follow a Low-potassium Diet?
Your doctor may recommend following a low-potassium diet if you have
kidney problems or are taking certain medications. If you have kidney problems,
excess potassium can build up to dangerous levels in your blood. This can
lead to confusion, irregular heartbeats, or a heart attack.
Why Follow a High-potassium Diet?
When combined with a low-sodium diet, a diet high in potassium can help
lower high blood pressure. This can help lower the risk of stroke and
other complications of high blood pressure. However, anyone with kidney
problems should not follow a high-potassium diet without first checking
with their doctor.Healthy kidneys excrete any excess intake of
potassium. When the kidneys don’t work properly, potassium builds up in
the body.
