Patients with appendicitis can eat sugar because it replenishes the calories that the body lacks. However, if it is before the surgery, it is not recommended to eat sugar. After the surgery, you can eat sugar in small amounts to replenish the body’s lack of components. As for the amount of sugar to be eaten, you can consult with your attending physician. Things that are not recommended to eat after having appendicitis are too spicy foods and drinks containing alcohol, and do not eat foods that are difficult to digest and tend to form hard stools. Fresh fruits, such as kiwi, apples and duck pears, can be consumed appropriately, as well as low-fat, high-quality protein, commonly fresh fish and shrimp, and leaner beef and lamb. Other dietary considerations can be made by consulting with the attending physician. After suffering from appendicitis, it is usually necessary to give antibiotics for treatment, and this is when alcohol is absolutely contraindicated, especially for the week before and the week after the use of cephalosporin antibiotics.
