Appendicitis

What is it?
Appendicitis is the inflammation of the appendix. The appendix is a worm-shaped pouch that projects from the cecum, which is the point at which the large intestine joins the small intestine. The appendix is located in the lower right abdomen and is not essential to the body’s function.
Who gets it?
Anyone can get appendicitis, and it is the most common reason for emergency abdominal surgery. Appendicitis is most likely to occur between the ages of 10 and 30. It occurs most often in boys between the ages of 10 and 14 and girls 15 to 19. It is less common in the elderly and infants.d
What causes it?
Researchers are not sure what causes appendicitis, but think it may be a blockage between the large intestine and appendix, or a viral or bacterial infection.
What are the symptoms?
An inflamed appendix causes mild to severe pain that moves from the navel to the lower right abdomen. The lower right abdomen may be extremely sensitive to touch and the pain is often worse with movement and strain, such as sneezing, coughing, or taking a deep breath. Other symptoms may include nausea, vomiting, loss of appetite, fever, diarrhea, constipation, weight loss, and a swollen abdomen. However, some people may not experience all of these symptoms. An inflamed appendix can become so swollen that it ruptures, spilling its infected contents into the abdominal cavity. This can cause a life-threatening infection called peritonitis. Never treat appendicitis symptoms with laxatives or enemas because they can cause the inflamed appendix to rupture. A ruptured appendix that is not treated immediately can cause death.
How is it diagnosed?
A diagnosis of appendicitis is based upon a physical examination and the patient’s symptoms. The doctor will ask you about the location of the pain and how long you have felt it. He or she will press gently on your abdomen to check for tenderness and swelling in the area of the appendix. The doctor may order blood tests to check for a high white blood count, which is a sign of infection, and ultrasound or computed tomography (CT) scans to check the condition of the appendix. He or she may order additional tests to rule out other disorders, such as urinary tract infections, tubal pregnancies, and bowel obstructions, that can cause similar symptoms. If you are a woman and your doctor suspects a cause other than appendicitis, he or she might recommend a laparoscopic study. A small, lighted viewing tube, called a laparoscope, is inserted into a small incision in the abdomen to check for disorders of the reproductive system.
What is the treatment?
Appendicitis is treated with surgery to remove the appendix, called an appendectomy. This surgery is usually performed as soon as possible after the diagnosis has been made to avoid a rupture. In many cases, appendectomies can be performed with laparoscopic surgery. The surgeon makes a small incision in the abdomen and inserts the laparoscope. The laparoscope is like a tiny video camera that gives the surgeon a clear view of the abdominal area. Other small incisions are made to insert the surgical instruments used to remove the appendix. Because the appendix is not necessary to the body’s function, people who have an appendectomy make a full recovery and are able to continue with life as usual.
Self-care tips
There is no known way to prevent appendicitis. However, a healthy lifestyle, including a diet high in fiber and antioxidants, as well as moderate exercise, goes a long way in preventing illness and disease.
