Abdominal Pain

What is it?

Abdominal pain is pain located in area of the stomach (abdomen), which is why it is frequently called "stomachache."  Abdominal pain in babies less than three months old, accompanied by fussy crying, is called colic.

Who gets it?

All children will experience abdominal pain at some point in their lives.

What causes it?

There are many possible causes of abdominal pain. In most cases, childhood abdominal pain is caused by overeating, a build up of gas, or a viral infection, called viral gastroenteritis or stomach flu. Abdominal pain is also often caused by stress. Teenage girls who have begun menstruating frequently experience abdominal pain, called cramps, during their period. When stomachaches occur frequently, it is referred to as recurrent abdominal pain. This type of pain can have many causes and should always be referred to a doctor. Common causes of recurrent abdominal pain include constipation, irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), gastroesophageal reflux disease (GERD), and carbohydrate malabsorption. Kidney or bladder infections and appendicitis can also cause abdominal pain.

What are the symptoms?

Abdominal pain can range from mild to severe, and can last anywhere from a few minutes to days, depending upon the cause. When the pain is caused by a stomach flu, it is accompanied by nausea, vomiting, and often diarrhea. If your child's abdominal pain is caused by stress and worry, he or she may describe a dull pain deep in the stomach, often around the belly button. Abdominal pain caused by a bladder or kidney infection is accompanied by pain during urination. A child with appendicitis will complain of sharp, severe pain, usually accompanied by vomiting of a dark substance called bile. Children with carbohydrate malabsorption will have symptoms that include bloating, flatulence, and loose stools. Stomach pain caused by a more serious condition is severe and/or constant, and is often accompanied by fever.

How is it diagnosed?

It is often difficult to diagnose the cause of abdominal pain in young children because they may have difficulty describing the pain. For this reason, doctors rely on the child's primary caregiver to give a complete history of the child's condition. Your doctor will want to know about any history of fever, vomiting, diarrhea, constipation, rectal bleeding, growth failure, or rashes. He or she will perform a thorough physical examination, especially concentrating on the area where your child is experiencing the pain. If your child has recurrent abdominal pain, your doctor will perform a rectal and stool examination, and take a blood sample for testing. He or she will check your child's liver and spleen for size and any tenderness. If the doctor suspects carbohydrate malabsorption , he will perform a breath test. Menstruating girls with recurring abdominal pain should have regular pelvic exams. 

What is the treatment?

Like the symptoms, treatment of abdominal pain depends upon the cause. For most cases of abdominal pain in children, rest and a diet of clear fluids are all that is needed to treat the pain. If your child is constipated, you can encourage him or her to sit on the toilet and relax to try to pass a bowel movement. It is extremely important to not use medications such as laxatives, enemas, or those to stop diarrhea unless your doctor has recommended it. If your child's abdominal pain is caused by stress, your doctor will suggest ways to ease the stress. These might include learning to recognize situations that trigger stress; ways to cope with stress, such as relaxation exercises; and psychotherapy. It's important to keep the worried child on a consistent daily schedule. Allowing the child to skip school or avoid normal daily activities because of stomach pain will only make the situation worse. If your child has recurring abdominal pain caused by a chronic or serious condition, your doctor will recommend a treatment plan specific to that condition. Abdominal pain caused by appendicitis is treated successfully by surgically removing the appendix.

Self-care tips

Never dismiss recurrent abdominal pain as psychological. While most abdominal pain caused by indigestion or flu can be treated with diet and rest, always call your doctor when stomach pain is accompanied by fever, vomiting, or diarrhea, or if the pain worsens steadily, is severe, or is recurring.
