This document discusses appendicitis, which is an inflammation of the appendix. The appendix is a small pouch connected to the colon on the right side of the abdomen. Symptoms of appendicitis include pain in the lower right abdomen that gets worse over time, nausea, vomiting, fever, and inability to pass gas. Diagnostic tests for appendicitis include physical exams like pressing on the abdomen to reproduce the pain. Treatment options are antibiotics for uncomplicated cases or an appendectomy to surgically remove the appendix for more severe cases. Complications can include peritonitis and sepsis if not treated.
