Acute appendicitis is the most common cause of abdominal pain among children and teenagers worldwide. They can be either acute or chronic. Acute appendicitis develops fast and can be removed using surgery. It can become severe, however, if not discovered and treated in time. Chronic appendicitis, on the other hand, develops slower and has less pronounced symptoms.
Acute appendicitis is caused by bacterial infections in the vermiform appendix, a tubular extension of the large intestine which functions as part of the digestive process. When the appendix is blocked by feces or it is squeezed by lymph nodes, it swells and usually doesn’t receive enough blood.
