What is the first thing most parents think of when their child has a bad stomach ache? Even if you aren't usually a paranoid parent, the idea of appendicitis is likely going to cross your mind.

Fortunately, there are many other conditions that are less serious that can be causing your child's stomach pain. But since appendicitis is a common condition, recognizing the symptoms of appendicitis is important.

Appendicitis Symptoms

Abdominal pain is the hallmark symptom of appendicitis. What can confuse people, though, is how the pain starts and can change. Most people associate appendicitis with right lower quadrant pain (the right lower side of the belly), but overlook the fact that the pain often starts as a more generalized pain or pain that is just around the belly button (periumbilical pain).

With classic appendicitis, the pain then moves to the right lower quadrant over the area of the appendix. The pain is worse with movement, and the child may have a hard time getting comfortable.

Other common appendicitis symptoms can include:

  • vomiting, although it is usually not repeated vomiting like you might have with a stomach virus
  • loss of appetite
  • nausea
  • abdominal swelling
  • low grade fever

Other appendicitis symptoms can sometimes include constipation, diarrhea, and urinating more often than usual.

Appendicitis symptoms usually worsen over 24 to 36 hours, afterwards, without treatment, the child's appendix may perforate. Symptoms will likely then get worse, with an increase in abdominal pain and development of a high fever.

Atypical Appendicitis Symptoms

Unfortunately, only about half of children have classic appendicitis symptoms.

That makes it important to seek medical attention whenever your child has right lower quadrant pain or you suspect that he may have appendicitis. Your pediatrician or emergency room doctors can then perform a physical exam and perhaps do tests to try to figure out if your child does indeed have appendicitis, even when he doesn't have classic appendicitis symptoms.

What You Need To Know

  • Abdominal pain followed by vomiting is commonly seen with appendicitis, while in most other causes of abdominal pain and vomiting -- such as a stomach virus -- the child will start vomiting first and then complain of abdominal pain.

  • Children with appendicitis will likely also have an elevated white blood count.

  • Other tests than can be helpful in diagnosing a child with appendicitis can include an ultrasound or CT scan, although they are not always necessary when a child has classic appendicitis symptoms.

  • The treatment for appendicitis is an appendectomy, which is the surgical removal of the inflamed appendix.

  • Although appendicitis is more common in older children, peaking in occurrence between the ages of 12 and 18 years, it can occur in young children, too. The diagnosis is more difficult though, as kids this age often don't complain of specific right lower quadrant pain and may just be irritable.
