What is a common symptom of hyperkalemia?

Muscle weakness or paralysis is a common symptom of hyperkalemia, which is an elevated level of potassium in the blood. Potassium is crucial for proper muscle function, including the muscles that control movement. When potassium levels are too high, it disrupts the normal electrical activity of muscle cells, which can lead to weakness or even paralysis. This can affect not only skeletal muscles but also the muscles involved in critical functions like respiration and heart rhythm.

Other symptoms of hyperkalemia may include fatigue, palpitations, and changes in heart rhythm, but muscle weakness or paralysis is particularly notable as it directly reflects the impact of high potassium levels on muscle cells' ability to contract and function properly. Thus, understanding this symptom is vital for recognizing and managing hyperkalemia effectively.
