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. As inflammation worsens, appendicitis pain typically increases and eventually becomes severe.

Although anyone can develop appendicitis, most often it occurs in people between the ages of 10 and 30. Standard treatment is surgical removal of the appendix.

Signs and symptoms of appendicitis may include:

• Sudden pain that begins on the right side of the lower abdomen
• Sudden pain that begins around your navel and often shifts to your lower right abdomen
• Pain that worsens if you cough, walk or make other jarring movements
• Nausea and vomiting
• Loss of appetite
• Low-grade fever that may worsen as the illness progresses
• Constipation or diarrhea
• Abdominal bloating
