Low potassium levels can cause various symptoms, mainly including: 1. Muscular symptoms: Manifested as weakness in the limbs, muscle weakness, easy fatigue; severe cases may present with flaccid paralysis or difficulty breathing, affecting respiratory muscle function. 2. Arrhythmias: Potassium ions are crucial for maintaining normal cardiac cell function; hypokalemia may lead to heart palpitations, tachycardia, arrhythmias, and other cardiac problems. 3.
