Question
A 9-year-old boy, who has been in good health, has recently been experiencing leg pain, weakness, and even difficulty walking. These symptoms are more pronounced after vigorous exercise and excessive sweating. The parents are inquiring about effective ways to replenish his blood potassium levels.
Answer
For cases of low blood potassium, oral administration of a 10% potassium chloride solution is one option. However, the safest and most effective method is to increase the intake of potassium-rich foods, especially fruits and vegetables. High-potassium fruits include bananas, strawberries, oranges, grapes, grapefruits, watermelons, etc., while spinach, sweet potatoes, soybeans, chicory, and scallions are also good sources of potassium. Additionally, it is important to avoid picky eating and maintain a balanced diet. If diagnosed with an endocrine disorder, immediate medical treatment should be sought in conjunction with a doctor, and personal hygiene should be maintained.
