    GlossaryHypokalemia

    condition where blood potassium levels are abnormally low

    Hypokalemia, also known as low potassium, is a condition where the potassium levels in the blood are lower than normal. Potassium is essential for proper muscle function, nerve signaling, and maintaining the body's fluid balance. Symptoms can include muscle weakness, cramping, fatigue, and in severe cases, life-threatening cardiac arrhythmias. Causes can range from excessive loss through urine or sweat, inadequate dietary intake, or certain medications.
