Question
After finishing the morning exercise, an individual suddenly felt difficulty breathing, accompanied by palpitations, nausea, and a desire to vomit but was unable to. Subsequently, they experienced weakness in all limbs, blurred vision, and finally fainted. Consciousness remained clear. They were transported to the hospital by ambulance for CT, brain scan, and blood tests. The results were all normal except for slightly low blood potassium. After receiving intravenous injections of potassium salt solution, they were allowed to return home.
Answer
After examination at the hospital, it was found that the blood potassium level was low, which could be the cause of the above symptoms. Hypokalemia may cause similar discomforts, and the most direct and effective treatment is to supplement potassium. It is recommended to avoid strenuous exercise in the near future, prevent excessive sweating, and increase the intake of foods rich in potassium to observe changes in the condition. If necessary, seek professional advice at the hospital again.
