Pain in the abdomen nearly always means something is wrong inside. It is nature’s warning signal to us and though it is about as welcome as “the plague,” it is rarely present without a good reason. To be brave about abdominal pain may mean strong character but certainly not long life, and serious disease in the abdomen is often allowed to progress to death’s door and beyond, simply because the pain was thought to be nothing serious.

When an organ within the abdomen is the source of pain, there is always some difficulty deciding which is the involved organ. Pain itself, however, gives many clues and frequently identifies its source.

How can we recognize a serious pain? Of the many pains and discomforts which are common in the abdomen, some are serious and others are of little importance.

A serious possibility is present-
1. If the pain has begun very recently (not months ago), and is very severe.
2. If the pain is associated with distention (blowing-up) of the abdomen.
3. If nausea and vomiting are present.
4. If the abdomen is hard or rigid and if pressing upon it causes great pain.
5. If it is also accompanied by bloody or tarry bowel movements.

Any of these characteristics lends importance to abdominal pain, whereas absence of all of them would accompany the probability of pain of lesser importance. Some of these less important pains might be stomach-ache due to “too many green apples,” minor food poisoning or mild constipation. Unimportant abdominal disturbances with mild pain are very common but in the event of any doubt, the physician should be consulted to rule out any serious possibility.

To study abdominal pain, let us examine each area of the abdomen separately to see which organ can produce pain in each area. Then we can study these organs individually and learn to identify the pain of each organ.

Upper Abdominal Pain. Abdominal pain above the umbilicus is likely to be caused by the stomach, liver, gallbladder or pancreas.

Stomach Pain. Pain from the stomach is felt in the upper abdomen. It is usually felt in the mid-line, occasionally goes through to the back and is caused mainly by ulcer and cancer.

Upper abdomen

Fig. 97. The upper abdomen is above the umbilicus and below the chest. Difficulties in this region include stomach, gallbladder, pancreas and liver-spleen diseases.

Peptic Ulcer and (gastritis) produces a burning or gnawing pain in the upper abdomen close to the mid-line, and has a characteristic identifying mark. It is relieved by food or alkali and it returns when the stomach is empty. Cancer Pain is about the same as ulcer pain, though not quite as severe and some people may have additional pain just as food is put into the stomach. In large, far-advanced cancer of the stomach, pain may be felt in the back, neck and elsewhere, depending upon spread of the disease. Stomach cancer cannot be identified with any certainty by the pain it produces. This is a job strictly for the physician.
