Whether or not having a child’s appendix removed has any effect on the body depends on the post-operative recovery. If there are no postoperative complications, there is usually no significant effect on the body. If it is only acute appendicitis, without causing acute peritonitis or adhesive bowel obstruction and other diseases, the appendectomy will have less impact on the child’s growth and development, basically no effect. The appendix belongs to the body’s immune organs, but with age, the immune function of the appendix will gradually weaken until disappear. As the immune function may not be fully formed in childhood, the appendix has a certain immune function, so appendectomy may lead to lower immune function of the child, this situation is usually temporary. In daily life, it is necessary to develop good living habits and actively participate in physical exercise to enhance the body’s immunity, which is conducive to the child’s growth and development.
