K35.8: Acute appendicitis, other and unspecified
Acute appendicitis refers to a sudden, severe inflammation of the appendix, a small pouch extending from the large intestine. This condition is usually identified by a tight, intense pain starting around the navel and later moving to the lower right side of the abdomen. Other common symptoms may include nausea, vomiting, loss of appetite, and fever. While the exact cause of acute appendicitis is often not clear, blockage of the appendix lumen, possibly by fecal matter or foreign bodies, is considered a common triggering factor. This blockage leads to an increase in pressure, finite blood flow, inflammation, and possible infection. If left untreated, appendicitis can progress and the appendix may burst, causing a perilous, widespread infection in the abdomen, known as peritonitis. This progression can happen within a span of 48 to 72 hours from the onset of symptoms. Acute appendicitis primarily affects the digestive system, but the subsequent infection can impact the entire body.
