Kidney Disease and Potassium
Potassium is a mineral found in many of the foods you eat. It plays a role in keeping your heartbeat regular and your muscles working right. It is the job of healthy kidneys to keep the right amount of potassium in your body. However, when your kidneys are not healthy, you often need to limit certain foods that can increase the potassium in your blood to a dangerous level. You may feel some weakness, numbness and tingling if your potassium is at a high level. If your potassium becomes too high, it can cause an irregular heartbeat or a heart attack.
