(HealthDay News) -- Your belly hurts and you have severe pain that moves from your belly button to your lower right side.

You also can't eat and are nauseous or vomiting.

You may have appendicitis, according to the U.S. National Digestive Diseases Information Clearinghouse.

Appendicitis occurs when a portion of the appendix becomes blocked. This usually leads to increased pressure, reduced blood flow, inflammation, and infection. If not treated promptly, the organ can rupture.

People who are at greater risk of appendicitis are diabetics, those undergoing chemotherapy, those with HIV, those who are obese, pregnant women, and infants and children.

If you suspect you have appendicitis, get to a doctor immediately.
