Appendicitis Overview
Appendicitis is the inflammation of the appendix — a small, finger-shaped pouch attached to the large intestine on the lower right side of the abdomen. It is a medical emergency that often requires surgical removal of the appendix (an appendectomy) to prevent serious complications.
This is one of the most common causes of abdominal pain requiring surgery, particularly among children, teens, and young adults, although it can occur at any age.
Classic symptoms of appendicitis include:
- Sudden pain starting near the belly button, moving to the lower right abdomen
- Loss of appetite
- Nausea and vomiting
- Fever
- Swelling or tenderness in the lower right abdomen
- Pain that worsens with movement, coughing, or sneezing
Because symptoms can vary, especially in young children, pregnant women, or the elderly, this is sometimes misdiagnosed as a stomach bug or urinary infection.
Early diagnosis and treatment are critical — a ruptured appendix can lead to life-threatening infection (peritonitis).
