Stomach aches are a common ailment of childhood. They can be triggered by many different factors. Most stomach aches are relatively minor, and may be caused by temporary factors such as stress or indigestion. Others may be more serious, including inflammation of the appendix (appendicitis), inflammation of the colon (colitis) or hepatitis.

A child’s abdomen is the region between the chest and the hips. It houses the stomach and intestines, as well as a number of other important organs. These include the bladder, kidneys, liver, spleen, pancreas, gallbladder, appendix and adrenal glands. Girls also have a uterus and ovaries in the abdomen.

A membrane called the peritoneum holds all of the contents of the abdomen in place. Three layers of abdominal muscles also support the abdomen.

Children who have a stomach ache experience a discomfort that varies widely, depending on the disorder that is causing the stomach ache. Some may have cramps and nausea, while others may experience pain that is limited to one area or that travels to other areas of the body. Pain can be mild or severe and may come and go or remain steady. Some stomach aches are sharp while others feel dull.

Although most stomach aches do not require medical care, some do. A physician will perform a complete physical examination and compile a thorough medical history when diagnosing the source of a stomach ache. Blood tests, urine tests, imaging tests and other procedures may be used to further pinpoint the source of a stomach ache.
