You can eat blueberries after appendicitis surgery. Appendicitis includes acute appendicitis and chronic appendicitis, and surgery is advocated for both acute and chronic appendicitis. Appendicitis surgery can be resumed in about 24 hours after the appendix, and patients are encouraged to get out of bed early to prevent intestinal adhesions. A light diet is usually advocated, avoiding overly oily, spicy and irritating foods to avoid aggravating the burden on the gastrointestinal tract. As a fruit, the main components of blueberry are fructose, fiber and vitamins. Patients after appendicitis surgery can eat blueberries after they have recovered from exhaustion and defecation, so they will not increase the burden on the gastrointestinal tract.
