Appendicitis is an inflammation of the appendix, a finger-shaped pouch that projects from your colon on the lower right side of your abdomen.

Appendicitis causes pain in your lower right abdomen. However, in most people, pain begins around the navel and then moves.

Symptoms

Signs and symptoms of appendicitis may include:

The site of your pain may vary, depending on your age and the position of your appendix. When you’re pregnant, the pain may seem to come from your upper abdomen because your appendix is higher during pregnancy.

When to see a doctor

Make an appointment with a doctor if you or your child has worrisome signs or symptoms. Severe abdominal pain requires immediate medical attention.

Causes

A blockage in the lining of the appendix that results in infection is the likely cause of appendicitis. The bacteria multiply rapidly, causing the appendix to become inflamed, swollen and filled with pus. If not treated promptly, the appendix can rupture.

Complications

Appendicitis can cause serious complications, such as:

Tests and diagnosis

Treatments and drugs

Appendicitis treatment usually involves surgery to remove the inflamed appendix. Before surgery you may be given a dose of antibiotics to prevent infection.

Surgery to remove the appendix (appendectomy)

Draining an abscess before appendix surgery

If your appendix has burst and an abscess has formed around it, the abscess may be drained by placing a tube through your skin into the abscess. Appendectomy can be performed several weeks later after controlling the infection.
