Appendicitis can cause nausea, primarily due to inflammation stimulating spasms in the gastrointestinal tract. In addition to nausea, symptoms include vomiting, abdominal pain, tenderness in the abdomen, and rebound pain. If vomiting and nausea are severe, timely appendectomy should be performed. Currently, laparoscopic appendectomy is common. This surgical method involves less bleeding during surgery and quicker postoperative recovery. After surgery, a semi-liquid diet can be chosen on days 1 to 2, and a normal diet can be resumed on days 3 to 5. It is also important to consume more vegetables and increase the intake of plant-based fiber thereafter.
