What is appendicitis?
Appendicitis is inflammation of your appendix. The appendix is a small pouch. It is attached to the large intestine on the lower right side of the abdomen. The appendix may get blocked by food or by part of a bowel movement that becomes hard. The appendix can become infected with bacteria or a virus. Appendicitis can also be caused by a parasite or tumor. You will need immediate care to prevent a ruptured appendix. A ruptured appendix can cause bacteria to leak into the abdomen. This can lead to a serious infection called peritonitis.
What are the signs and symptoms of appendicitis?
Symptoms may start suddenly. The most common symptom is pain that starts at the belly button and moves to the lower right side of your abdomen. The pain worsens when you touch your abdomen, move, sneeze, cough, or take a deep breath. You may also have any of the following:
- Abdomen that feels hard
- Diarrhea or constipation
- Loss of appetite
- Nausea or vomiting
How is appendicitis diagnosed?
Your healthcare provider will examine you and check for pain or tenderness in your abdomen. You may also need any of the following:
- Blood tests may show if you have an infection.
- A urine test may be used to check for a urinary tract infection or kidney stone.
- CT or ultrasound pictures of your abdomen may be used to check your appendix. You may be given contrast liquid to help your appendix show up better in the pictures. Tell the healthcare provider if you have ever had an allergic reaction to contrast liquid.
How is appendicitis treated?
- Medicines may be given to fight an infection or to manage pain. Ask your healthcare provider how to take pain medicine safely.
- Drainage may be needed if you develop an abscess after a burst appendix. To drain the abscess, your healthcare provider guides a tube through your skin and into the abscess. Infected fluid drains through the tube.
- An appendectomy is surgery to remove your appendix. Your appendix may be removed through small incisions in your abdomen. If your appendix has burst, you may need an open appendectomy. A single, larger incision is made to remove the appendix and clean out the abdomen.
The following list of medications are in some way related to or used in the treatment of this condition.
