Abdominal Pain - Timely Diagnosis Medical Author: Jay W. Marks, M.D. Medical Editor: Melissa Conrad Stöppler, MD When a medical problem comes on quickly or occurs periodically over a longer period, it is often best to move quickly and make a diagnosis while symptoms are still present. The more serious the problem, the greater the urgency. Nevertheless, urgency should never replace careful and complete diagnostic testing, as is illustrated by a recent experience. I was asked to see a patient, a young man in his late twenties, who for several years had been having episodes of abdominal pain. There was nothing very distinctive about the pain except that it would last from hours to one or two days and then disappear. During the episodes, he would not eat; he also noted some nausea. He had visited an emergency room once, but only limited testing had been done, and no diagnosis was made. At a later time, he had been seen by a gastroenterologist who had performed an upper gastrointestinal endoscopy. No abnormalities were found by endoscopy. The patient was healthy except for the bouts of abdominal pain. Despite discussing his medical history in detail and examining him, I could find no clues to the cause of his problem. Since the episodes always resolved completely, I thought the best course of action would be to see him during an episode of pain. By examining the patient during an episode, I hoped to be able to decide on the best diagnostic course. It took almost 12 months, but finally, early one morning I got a call from the patient. A typical episode of abdominal pain was beginning...

What is abdominal pain?

Abdominal pain is pain that is felt in the abdomen. The abdomen is an anatomical area that is bounded by the lower margin of the ribs above, the pelvic bone (pubic ramus) below, and the flanks on each side. Although abdominal pain can arise from the tissues of the abdominal wall that surround the abdominal cavity (i.e., skin and abdominal wall muscles), the term abdominal pain generally is used to describe pain originating from organs within the abdominal cavity (i.e., beneath the skin and muscles). These organs include the stomach, small intestine, colon, liver, gallbladder, and pancreas. Occasionally, pain may be felt in the abdomen even though it is arising from organs that are close to but not within the abdominal cavity, for example, the lower lungs, the kidneys, and the uterus or ovaries. This latter type of pain is called "referred" pain because the pain, though originating outside the abdomen, is being referred to (felt) in the abdominal area.

What causes abdominal pain?

Abdominal pain is caused by inflammation (e.g., appendicitis, diverticulitis, colitis ), by stretching or distention of an organ (e.g., obstruction of the intestine, blockage of a bile duct by gallstones, swelling of the liver with hepatitis), or by loss of the supply of blood to an organ (e.g., ischemic colitis). To complicate matters, however, abdominal pain also can occur without inflammation, distention or loss of blood supply. An important example of this latter type of pain is the irritable bowel syndrome (IBS). It is not clear what causes the abdominal pain in IBS, but it is believed to be due either to abnormal contractions of the intestinal muscles (e.g., spasm) or abnormally sensitive nerves within the intestines that give rise to painful sensations inappropriately (visceral hyper-sensitivity).
