Potassium disorders refer to imbalances in the level of potassium, an essential mineral in the body. These imbalances can lead to either hyperkalemia, which is an excess of potassium, or hypokalemia, which is a deficiency. Both conditions can affect heart function, muscle contractions, and overall cellular processes. Causes of potassium disorders can include kidney problems, certain medications, and dietary factors. Symptoms may vary but can include muscle weakness, fatigue, and irregular heartbeats. Proper diagnosis and treatment are crucial to managing these disorders and maintaining healthy potassium levels in the body.
