What causes appendicitis in children?

Appendicitis in children is a common acute abdominal pain disorder that usually occurs in children and adolescents. Appendicitis is inflammation and infection of the appendix, which if left untreated can lead to serious complications such as peritonitis and septic shock. So, what causes appendicitis in children? Let’s learn more about it below. Bacterial Infection in the Appendiceal Cavity The main cause of appendicitis is bacterial infection in the appendiceal cavity. Normally, the appendix is ​​a small bag located at the end of the cecum. If the passage in the appendix becomes blocked, bacteria can multiply inside the appendix, causing infection and inflammation. Common causes of obstruction include: (1) Bezoars: Eating a high-fat, high-protein, and low-fiber diet for a long time can easily form bezoars, leading to blockage of the appendiceal passage. (2) Infection: Infections in other parts of the body, such as respiratory tract infections, gastrointestinal infections, etc., may also spread to the appendix through blood circulation, causing infection and inflammation. Local injury to the appendix Another cause of appendicitis is local injury to the appendix. For example, appendicitis may also occur when the appendix is ​​subjected to severe mechanical stimulation, such as movement, jumping, falling, etc. Additionally, the appendix can be chemically irritated, for example due to acid reflux or bile reflux. Genetic factors Some studies suggest that appendicitis may be related to genetic factors. For example, certain genetic mutations may lead to abnormal morphology and structure of the appendix, predisposing it to appendicitis. Other Factors In addition to the above reasons, there are some other factors that may cause appendicitis in children, including: (1) Immune system abnormalities: If a child\’s immune system is abnormal, bacterial infections may occur and spread more easily. (2) Age: Children’s appendices are more susceptible to appendicitis because their appendices are not fully developed and mature, and the passage is narrow. (3) Gender: Girls are more likely to develop appendicitis than boys, which may be related to the fact that girls’ appendix is ​​more susceptible to compression and damage. In short, appendicitis in children is caused by many reasons, including bacterial infection in the appendix cavity, local injury to the appendix, genetic factors, etc. If a child develops abdominal pain, fever, vomiting and other symptoms, parents should seek medical advice promptly to avoid worsening of the condition.
