Appendicitis is a condition characterized by inflammation of the appendix. This small tube-shaped organ is attached to the colon and is part of the digestive system. Although the appendix serves no real purpose, it can cause serious problems when inflamed. Untreated appendicitis can cause the organ to rupture, leading to death.Symptoms of AppendicitisThe first symptom of appendicitis is usually aching pain that begins near the naval before shifting to the right side of the abdomen. The pain generally increases over the next few hours. Many patients report a feeling of tenderness when the area above the appendix is touched. Pressure may also result in feelings of sharp, intense pain. Discomfort is often made worse by moving, coughing or other fast movements. Many patients experience vomiting, constipation, diarrhea, nausea, fever and swelling in the abdomen.Causes of AppendicitisAppendicitis is often caused by an obstruction in the appendix. Blockage may be caused by food that has not been fully digested or by fecal matter. The condition may also be caused by an infection.Complications of AppendicitisLeft untreated, appendicitis can cause serious health complications. The organ may rupture, causing infectious agents and the contents of the intestines to seep into the abdomen. This can lead to an infection in the abdominal cavity. Once the appendix has ruptured, an abscess may form around the organ. An abscess is a collection of infectious pus that must be treated before it tears. A torn abscess can cause further infection in the abdominal cavity.Treatment of AppendicitisAppendicitis must be treated immediately to avoid rupture. An appendectomy is a simple surgical procedure to remove the organ using either traditional surgical methods or laparoscopic technologies. If the appendix has already ruptured and an abscess has formed, the infectious pus must be drained before an appendectomy is performed. The surgery will only take place after the infection is completely cleared.
