Potassium is a crucial electrolyte that plays a vital role in maintaining proper nerve and muscle function, especially in the heart. It helps regulate fluid balance, nerve signals, and muscle contractions. The potassium test measures the level of this electrolyte in the blood, which is tightly controlled by the kidneys. Abnormal levels can indicate kidney problems, dehydration, or other health issues. Certain medications, particularly diuretics and some blood pressure medications, can affect potassium levels. Maintaining the right balance of potassium is essential for overall health and proper functioning of various bodily systems.
A low potassium level (hypokalemia) can be dangerous and may indicate:
Symptoms may include muscle weakness, fatigue, irregular heartbeat, and in severe cases, paralysis. Immediate medical attention is often necessary to prevent complications, especially related to heart function.
