    Clinical Overview
    Reviewed by Dr. Rich Alweis

    During normal digestion, food moves from the mouth down the esophagus into the stomach. The stomach produces hydrochloric acid and an enzyme called pepsin to digest the food. From the stomach, food passes into the upper part of the small intestine, called the duodenum, where digestion and nutrient absorption continue.

    An ulcer is a sore or lesion that forms in the lining of the stomach or duodenum where acid and pepsin are present. Ulcers in the stomach are called gastric or stomach ulcers. Those in the duodenum are called duodenal ulcers. In general, ulcers in the stomach and duodenum are referred to as peptic ulcers. Ulcers rarely occur in the esophagus or in the first portion of the duodenum, the duodenal bulb.

    About 20 million Americans develop at least one ulcer during their lifetime. Each year ulcers affect about 4 million people. Of these people, more than 40,000 people have surgery because of persistent symptoms or problems from ulcers. About 6,000 people die of ulcer-related complications.

    Ulcers can develop at any age, but they are rare among teenagers and children each year. Duodenal ulcers occur for the first time usually between the ages of 30 and 50. Stomach ulcers are more likely to develop in people over age 60. Duodenal ulcers occur more frequently in men than women; stomach ulcers develop more often in women than men.

    For almost a century, doctors believed lifestyle factors such as stress and diet caused ulcers. Later, researchers discovered that an imbalance between digestive fluids (hydrochloric acid and pepsin) and the stomach's ability to defend itself against these powerful substances resulted in ulcers. Today, research shows that most ulcers develop as a result of infection with bacteria called Helicobacter pylori (H. pylori). While all three of these factors play a role in ulcer development, H. pylori is now considered the primary cause.

    Lifestyle

    While scientific evidence refutes the old belief that stress and diet cause ulcers, several lifestyle factors continue to be suspected of playing a role. These factors include cigarettes, foods and beverages containing caffeine, alcohol, and physical stress.

  • Smoking: Studies show that cigarette smoking increases one's chances of getting an ulcer. Smoking slows the healing of existing ulcers and also contributes to ulcer recurrence.

  • Caffeine: Coffee, tea, colas, and foods that contain caffeine seem to stimulate acid secretion in the stomach, aggravating the pain of an existing ulcer. However, the amount of acid secretion that occurs after drinking decaffeinated coffee is the same as that produced after drinking regular coffee. Thus, the stimulation of stomach acid cannot be attributed solely to caffeine.

  • Alcohol: Research has not found a link between alcohol consumption and peptic ulcers. However, ulcers are more common in people who have cirrhosis of the liver, a disease often linked to heavy alcohol consumption.

  • Stress: Although emotional stress is no longer thought to be a cause of ulcers, people with ulcers often report that emotional stress increases ulcer pain. Physical stress, however, increases the risk of developing ulcers particularly in the stomach. For example, people with injuries such as severe burns and people undergoing major surgery often require rigorous treatment to prevent ulcers and ulcer complications.

  • Acid and pepsin: Researchers believe that the stomach's inability to defend itself against the powerful digestive fluids, acid and pepsin, contributes to ulcer formation. The stomach defends itself from these fluids in several ways. One way is by producing mucus--a lubricant-like coating that shields stomach tissues. Another way is by producing a chemical called bicarbonate. This chemical neutralizes and breaks down digestive fluids into substances less harmful to stomach tissue. Finally, blood circulation to the stomach lining, cell renewal, and cell repair also help protect the stomach.

    Nonsteroidal anti-inflammatory drugs (NSAIDs) make the stomach vulnerable to the harmful effects of acid and pepsin. NSAIDs such as aspirin, ibuprofen, and naproxen sodium are present in many non-prescription medications used to treat fever, headaches, and minor aches and pains. These, as well as prescription NSAIDs used to treat a variety of arthritic conditions, interfere with the stomach's ability to produce mucus and bicarbonate and affect blood flow to the stomach and cell repair. They can all cause the stomach's defense mechanisms to fail, resulting in an increased chance of developing stomach ulcers. In most cases, these ulcers disappear once the person stops taking NSAIDs.
