Appendix surgery, or appendectomy, treats appendicitis, an inflammation of the appendix, a small organ in the lower right abdomen. Appendicitis is often caused by a blockage, leading to bacterial growth and swelling. Symptoms include sharp abdominal pain (especially lower right), fever, nausea, vomiting, and loss of appetite. If untreated, the appendix can rupture, causing severe infection. Surgery is the standard treatment, typically performed laparoscopically with small incisions for quicker recovery. Open surgery may be used for complicated cases like rupture. Post-surgery, patients usually recover within days to weeks, with minimal complications. Risks include infection or abscess formation. Early diagnosis and surgery are critical to prevent rupture. Patients can live normally without the appendix, as it has no essential function, and dietary or lifestyle changes are rarely needed post-recovery.
