This video from the National Kidney Foundation highlights the importance of maintaining the right amount of potassium in the body, as it is vital for the proper functioning of nerves, muscles, and the heart. High potassium, or hyperkalemia, can lead to serious heart problems and is often caused by a diet high in potassium, certain medications, and diseases like diabetes, heart disease, and kidney disease. It is common in people with kidney disease, as unhealthy kidneys can’t control potassium levels effectively. Symptoms of high potassium include muscle weakness, numbness, tiredness, and nausea, but many people experience no symptoms. Immediate medical help is needed if symptoms like nausea, vomiting, shortness of breath, irregular heartbeat, or chest pain occur. Regular checkups and following a treatment plan are crucial, even without symptoms. Early detection and treatment of kidney disease can lead to a positive prognosis.
