What are the symptoms of potassium deficiency in the body?

Potassium deficiency can lead to fatigue, muscle cramps, irregular heartbeat, and other symptoms. In severe cases, it may even endanger life. If obvious symptoms appear, please seek medical attention promptly to check blood potassium levels.

Potassium is an essential electrolyte that plays a critical role in maintaining nerve signal transmission, muscle contraction, and heart function. Normally, a balanced diet can meet the body's potassium needs. However, excessive potassium loss, which may result from overly strict dietary control, dehydration, diarrhea, and other conditions, can lead to potassium deficiency.

Mild potassium deficiency may be the body's early "distress signal." For instance, fatigue may be the first symptom to appear as energy metabolism is affected when cells lack potassium. Muscle cramps or weakness are also common, similar to a smartphone slowing down when its battery is low. When the body's muscles lose "electrolyte" support, they exhibit coordination issues.

Severe potassium deficiency may cause abnormal heart rates, such as tachycardia or arrhythmia, because potassium is crucial for the electrical conduction of cardiomyocytes.

To prevent potassium deficiency, consume potassium-rich foods such as bananas, potatoes, spinach, and avocados. During cooking, avoid boiling in excess water as potassium easily dissolves in it. For those who exercise regularly or sweat excessively, appropriate supplementation with sports drinks can help balance electrolytes.

If potassium loss is caused by illness or medications (such as diuretics), consult a doctor for professional advice. In case of severe symptoms like arrhythmia or severe fatigue, seek medical attention immediately.
