What are the symptoms of low potassium levels (hypokalemia)?

Hypokalemia, or low potassium levels, can cause symptoms like muscle weakness, cramps, fatigue, constipation, and, in severe cases, irregular heartbeats. It often results from conditions like dehydration, vomiting, diarrhea, or the use of diuretics. Identifying hypokalemia through a potassium test allows for prompt treatment, such as dietary adjustments or potassium supplements, to restore normal levels and prevent complications.
