The exact cause is not known. It is thought to be caused by something trapped in the appendix, such as:
- Stool (poop)
- A piece of food
- Scar tissue
- Overgrowth of the lymph tissue of the appendix
Pain is the most common problem. The pain may:
- Start as discomfort around the belly button before moving to the right side of the belly
- Slowly get worse over time
- Worsen when moving, sneezing, coughing, or deep breathing
Other problems may be:
- Loss of appetite
- Nausea and vomiting
- Swelling of the belly
- A hard belly that hurts when it is touched
If the appendix bursts, a person may have:
- Severe pain that spreads across the belly
- A fever that gets higher
Note: Symptoms may be different in infants, children, older adults, and people who are pregnant.
The doctor will ask about symptoms and health history. A physical will be done. It will focus on the belly. This may be enough to suspect appendicitis.
Blood and urine tests may be done to look for changes.
Images may be taken of the belly. This can be done with:
- CT scan
- MRI scan
If the diagnosis is not clear, a surgery called a laparoscopy may be done to view inside the belly.
Antibiotics can help treat the infection. Those with mild symptoms may get better and not need surgery right away. Most will need surgery to remove their appendix. This is called an appendectomy. It may need to be done right away.
