• Cause: Appendicitis occurs when the appendix becomes blocked, often by stool, a foreign body, or cancer. Blockage can also occur from infection, as the appendix swells in response to any infection in the body.
• Complications: If left untreated, the appendix can rupture, spreading infection throughout your abdomen (peritonitis). This can be life-threatening and requires immediate surgery to remove the appendix and clean the abdominal cavity. Source: National Institute of Diabetes and Digestive and Kidney Diseases

The standard treatment for appendicitis is surgical removal of the appendix, known as an appendectomy. This can be performed as an open surgery or laparoscopically (using small incisions and a camera). In some cases, antibiotics alone may be used to treat mild appendicitis.

• Surgery (Appendectomy): Usually recommended to remove the inflamed appendix as quickly as possible.
• Antibiotics: May be used before surgery or, in some mild cases, as the primary treatment.
