Appendicitis happens when your appendix, a small finger-shaped structure that protrudes from your large intestine on the right side, gets inflamed. Abdominal pain, nausea, and vomiting are more common during pregnancy and may or may not be the signs of appendicitis. The appendix is a small pouch attached to the beginning of your large intestine.
When the appendix is blocked, it becomes inflamed and results in a condition termed appendicitis. The disease involves inflammation and infection of the vermiform appendix, a tube-shaped extension of the cecum. Appendicitis typically starts with a pain in the middle of your abdomen (tummy) that may come and go. The appendix is a narrow pouch, shaped like a finger, which is attached to the colon, on the right side of the abdomen.
