Acute appendicitis may be caused by blockage of the appendiceal lumen, pathogenic infection, and appendiceal fecaliths. Acute appendicitis is an acute inflammation of the appendix due to a variety of causes and is one of the common surgical disorders. The causes of acute appendicitis include obstruction of the appendiceal lumen, pathogenic infections, lymphoid follicular hyperplasia, appendiceal fecaliths, appendiceal tumors, ascending colon cancer, and other factors. Patients often present with symptoms of abdominal pain, and the disease starts with paroxysmal pain around the umbilicus and epigastrium, and as the disease progresses, the abdominal pain can be transferred to the right lower abdomen. Some patients may also have anorexia, nausea, vomiting, diarrhea, and decreased defecation. Once patients have symptoms suspected of acute appendicitis, they should go to a regular hospital and take relevant treatment measures under the guidance of a doctor. In daily life, regular meals, eat more fiber-rich food, prevent constipation, can reduce the occurrence of acute appendicitis.
