In cases of hyperkalemia, it is important to avoid eating foods high in potassium, such as corn, lettuce, carp, eel, lamb, beef, pork, as well as dates, bananas, and others. These foods are rich in potassium and should be consumed less or not at all. Additionally, a diet high in sugar and fat should be provided, or some intravenous nutrition may be used, to ensure sufficient caloric intake and prevent the release of potassium from metabolic breakdown, which could lead to an increase in blood potassium levels. Also, it is important to avoid certain medications high in potassium, such as traditional Chinese medicines. (Medication use should be under the guidance of a professional doctor.)
