What is a common symptom of hypokalemia?

Weakness is a prevalent symptom of hypokalemia, which refers to low potassium levels in the blood. Potassium plays a crucial role in neuromuscular function, and when levels are insufficient, muscle cells can become less excitable. This reduced excitability leads to generalized weakness as the strength and coordination of muscle contractions are compromised.

Hypokalemia can also contribute to other symptoms such as muscle cramping and fatigue. However, weakness is often emphasized because it directly relates to muscle function and can significantly impair a person's ability to perform daily activities. This is why weakness is commonly associated with hypokalemia in clinical settings and is often one of the first signs noted in patients.
