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.


What is Potassium?

Potassium is a mineral needed by the body for proper functioning of nerves and muscles and for the regulation of heartbeat. The body’ main source of Potassium is foods eaten each day.

What does that mean to me?

High levels of potassium in your blood could cause your heart to stop if blood potassium levels are too high.
What can be done to avoid this?
