appendicitis
INFLAMMATION of the vermiform APPENDIX , which, in its acute form, is the most common abdominal emergency in the western world, usually requiring treatment by APPENDICECTOMY . It is most common in young people during their first 20 years, and the symptoms include abdominal pain which may move about, appetite loss, sickness and diarrhoea. If not treated the appendix can become the site of an ABSCESS , or gangrenous, which eventually may result in PERITONITIS . This arises because infected material spreads from the burst appendix into the peritoneal cavity.
The appendix is a small, tube-like organ attached to the first part of the large intestine. It is located in the lower right part of the abdomen. It has no known function. A blockage inside of the appendix causes appendicitis. The blockage leads to increased pressure, problems with blood flow, and inflammation. If the blockage is not treated, the appendix can burst and spread infection into the abdomen. This causes a condition called peritonitis.
The main symptom is pain in the abdomen, often on the right side. It is usually sudden and gets worse over time. Other symptoms may include:
- Swelling in the abdomen
- Loss of appetite
- Nausea and vomiting
- Constipation or diarrhea
- Inability to pass gas
- Low fever
Not everyone with appendicitis has all these symptoms.
Appendicitis is a medical emergency. Treatment almost always involves removing the appendix. Anyone can get appendicitis, but it is more common among people 10 to 30 years old.
