What is one potential complication of untreated appendicitis?

Untreated appendicitis can lead to perforation of the appendix, which is a serious complication. When the appendix becomes inflamed and swollen, it can eventually burst if not addressed, spilling infectious material into the abdominal cavity. This can trigger peritonitis, an inflammation of the peritoneum, the lining of the abdominal cavity, which can be life-threatening and requires immediate medical intervention. The rapid onset of peritonitis can lead to widespread infection, sepsis, and potentially severe health consequences if not treated promptly.

The other options do not directly relate to the complications arising from untreated appendicitis. Chronic abdominal pain can occur for various reasons but is not a direct complication of appendicitis. The appendix does not regenerate after being removed or after an episode of appendicitis. Gallbladder disease is unrelated to appendicitis and typically involves different pathophysiological processes. Therefore, the risk of perforation leading to peritonitis clearly stands out as a potential complication of untreated appendicitis.
