• Limiting Potassium in Your Diet

    Potassium can be found in many foods. Abnormal blood levels of potassium can be very dangerous as they may lead to serious heart arrhythmias . Kidneys regulate the metabolism of potassium, making sure that its levels are appropriate. However, when your kidneys are not working properly, you often need to limit certain foods that can increase the potassium in your system.
    If you need to limit your potassium, your doctor or dietitian will tell you how many milligrams (mg) you can have each day. They will also help you design a low potassium diet .
