Ulcers

Peptic ulcers are sores that develop in the stomach, the beginning of the small intestine, or the esophagus. The most common causes of ulcers are a bacterial infection and the use of anti-inflammatory drugs such as ibuprofen or aspirin. Although food and stress can worsen the symptoms of an ulcer, they do not cause ulcers. Typical symptoms include low burning pain between meals, vomiting, nausea, burping, or weight loss. In severe cases, sharp pain, bloody vomiting, or bloody stools may be a warning sign of an ulcer that is a serious issue. While there are several preventative lifestyle changes, ulcers caused by bacterial infection are typically treated with a combination of antibiotics and acid-reducing medicines. If you have a mild or severe peptic ulcer, let Dr. Cofrancesco and Dr. Quijano at GI North provide a specific treatment plan for you.

What is a peptic ulcer?

A peptic ulcer is a sore on the lining of the stomach or duodenum, the beginning of the small intestine. Less commonly, a peptic ulcer may develop just above the stomach in the esophagus, the tube that connects the mouth to the stomach. A peptic ulcer in the stomach is called a gastric ulcer. One that occurs in the duodenum is called a duodenal ulcer. People can have both gastric and duodenal ulcers at the same time. They also can develop peptic ulcers more than once in their lifetime. Peptic ulcers are common. Each year in the United States, about half a million people develop a peptic ulcer.*

What causes peptic ulcers?

A bacterium called Helicobacter pylori (H. pylori) is a major cause of peptic ulcers. Nonsteroidal anti-inflammatory drugs (NSAIDs), such as aspirin and ibuprofen, are another common cause. Rarely, cancerous or noncancerous tumors in the stomach, duodenum, or pancreas cause ulcers. Peptic ulcers are not caused by stress or eating spicy food, but both can make ulcer symptoms worse. Smoking and drinking alcohol also can worsen ulcers and prevent healing.

What is H. pylori?

H. pylori is a type of bacteria—a germ that may cause infection. H. pylori infection is common, particularly in developing countries, and often begins in childhood. Symptoms usually don’t occur until adulthood, although most people never have any symptoms.

H. pylori causes more than half of peptic ulcers worldwide.* The bacterium causes peptic ulcers by damaging the mucous coating that protects the stomach and duodenum. Damage to the mucous coating allows powerful stomach acid to get through to the sensitive lining beneath. Together, the stomach acid and H. pylori irritate the lining of the stomach or duodenum and cause an ulcer.

Yet, most people infected with H. pylori never develop ulcers. Why the bacterium causes ulcers in some people and not in others is not known. Most likely, development of ulcers depends on characteristics of the infected person; the type, or strain, of H. pylori present; and factors researchers have yet to discover.

How is H. pylori spread?

Researchers are not certain how H. pylori is transmitted, although they think it may be spread through contaminated food or water. People may pick up the bacterium from food that has not been washed well or cooked properly or from drinking water that has come from an unclean source. Other research is exploring how infection spreads from an infected person to an uninfected person. Studies suggest that having contact with the stool or vomit of an infected person can spread H. pylori infection. And H. pylori has been found in the saliva of some infected people, which means infection could be spread through direct contact with saliva.

What are the symptoms of a peptic ulcer?

Abdominal discomfort is the most common symptom of both duodenal and gastric ulcers. Felt anywhere between the navel and the breastbone, this discomfort usually

  • is a dull or burning pain
  • occurs when the stomach is empty—between meals or during the night
  • may be briefly relieved by eating food, in the case of duodenal ulcers, or by taking antacids, in both types of peptic ulcers
  • lasts for minutes to hours
  • comes and goes for several days or weeks

Other symptoms include

  • weight loss
  • poor appetite
  • bloating
  • burping
  • nausea
  • vomiting

Some people experience only mild symptoms or none at all.

Emergency Symptoms

If you have any of the following symptoms should call Dr. Cofrancesco or Dr. Quijano right away:

  • sharp, sudden, persistent, and severe stomach pain
  • bloody or black stools
  • bloody vomit or vomit that looks like coffee grounds


These “alarm” symptoms could be signs of a serious problem, such as

  • bleeding—when acid or the peptic ulcer breaks a blood vessel
  • perforation—when the peptic ulcer burrows completely through the stomach or duodenal wall
  • obstruction—when the peptic ulcer blocks the path of food trying to leave the stomach

How is an H. pylori-induced ulcer diagnosed?

Noninvasive Techniques

If you have peptic ulcer symptoms, Dr. Cofrancesco and Dr. Quijano first ask about use of over-the-counter and prescription NSAIDs. Patients who are taking an NSAID are asked to stop, reduce the dose, or switch to another medication. Then Dr. Cofrancesco or Dr. Quijano tests to see if H. pylori is present. Testing is important because H. pylori-induced ulcers are treated differently than ulcers caused by NSAIDs.

Dr. Cofrancesco and Dr. Quijano may use one of three simple, noninvasive tests to detect H. pylori in your blood, breath, or stool. Each test described below is easily performed, often in an outpatient setting.

Blood test. A blood sample is taken from the your vein and tested for H. pylori antibodies. Antibodies are substances the body produces to fight invading harmful substances—called antigens—such as the H. pylori bacterium.

Urea breath test. You swallow a capsule, liquid, or pudding that contains urea “labeled” with a special carbon atom. After a few minutes, you breathe into a container, exhaling carbon dioxide. If the carbon atom is found in the exhaled breath, H. pylori is present, as this bacterium contains large amounts of urease, a chemical that breaks urea down into carbon dioxide and ammonia.

Stool antigen test. You provide a stool sample, which is tested for H. pylori antigens.

Invasive Techniques

If you have any alarm symptoms, Dr. Cofrancesco or Dr. Quijano orders an endoscopy or upper gastrointestinal (GI) series. It is generally recommended that these tests be run if you first experience peptic ulcer symptoms around age 50. Often performed as outpatient procedures, both procedures are painless and allow Dr. Cofrancesco or Dr. Quijano to look inside your stomach and duodenum. For an endoscopy, you are lightly sedated. Dr. Cofrancesco ir Dr. Quijano passes an endoscope—a thin, lighted tube with a tiny camera on the end—into the patient’s mouth and down the throat to the stomach and duodenum. With this tool, Dr. Cofrancesco and Dr. Quijano can closely examine the lining of the esophagus, stomach, and duodenum.

Dr. Cofrancesco or Dr. Quijano can use the endoscope to take photos of ulcers or remove a tiny piece of tissue—no bigger than a match head—to view with a microscope. This procedure is called a biopsy. The biopsied tissue is examined to see if H. pylori is present. If an ulcer is bleeding, the doctor can use the endoscope to inject medicines that help the blood clot or to guide a heat probe that burns tissue to stop bleeding—a process called cauterization. For an upper GI series, you drink a white, chalky liquid called barium. The barium makes the esophagus, stomach, and duodenum and any ulcers show up on an x ray. Sedation is not necessary for this procedure.

How is an H. pylori-induced ulcer treated?

Peptic ulcers caused by H. pylori are treated with drugs that kill the bacteria, reduce stomach acid, and protect the stomach and duodenal lining. Antibiotics are used to kill H. pylori. Antibiotic regimens may differ throughout the world because some strains of H. pylori have become resistant to certain antibiotics—meaning that an antibiotic that once destroyed the bacterium is no longer effective. Medicines that reduce stomach acid include proton pump inhibitors (PPIs) and histamine receptor blockers (H2 blockers). Both acid-reducing medicines help relieve peptic ulcer pain after a few weeks and promote ulcer healing. PPIs and H2 blockers work in different ways:

    • PPIs suppress acid production by halting the mechanism that pumps acid into the stomach.
    • H2 blockers work by blocking histamine, which stimulates acid secretion.

While PPIs cannot kill H. pylori, research shows they do help fight the H. pylori infection. Research also shows that after 4 weeks of treatment, patients taking PPIs had earlier pain relief and better healing rates than those taking H2 blockers.

Bismuth subsalicylate (Pepto-Bismol) coats ulcers, protecting them from stomach acid. Although bismuth subsalicylate may kill H. pylori, it is used with—not in place of—antibiotics in some treatment regimens.In the United States, clarithromycin-based triple therapy—triple therapy, for short—is the standard treatment for an ulcer caused by H. pylori. Dr. Cofrancesco and Dr. Quijano prescribe the antibiotic clarithromycin, a PPI, and the antibiotics amoxicillin or metronidazole for 10 to 14 days.

Bismuth quadruple therapy is another treatment strategy used in the United States. You take a PPI, bismuth subsalicylate, and the antibiotics tetracycline and metronidazole for 10 to 14 days. Bismuth quadruple therapy is used to treat patients in one of several situations, including if you

        • cannot take amoxicillin—a penicillin-like antibiotic—because of a penicillin allergy
        • has been treated before with a macrolide antibiotic, such as clarithromycin
        • is still infected with H. pylori because triple therapy failed to kill the bacteria


Triple therapy and bismuth quadruple therapy may cause nausea and other side effects, including

        • stomach upset
        • diarrhea
        • headache
        • a metallic taste
        • a darkened tongue or stools
        • flushing when drinking alcohol
        • sensitivity to the sun

You should discuss any bothersome side effects with Dr. Cofrancesco or Dr. Quijano, who may prescribe other medicines to kill the bacteria and cure the ulcer. Although antibiotics can cure 80 to 90 percent of ulcers caused by H. pylori, eliminating the bacteria can be difficult. You must take all medicines exactly as prescribed, even when the peptic ulcer pain is gone.

At least 4 weeks after treatment, Dr. Cofrancesco or Dr. Quijano tests patients using a breath or stool test to be sure the H. pylori infection has been cured. Blood tests are not useful after treatment because your blood can test positive for H. pylori even after the bacteria have been eliminated. If infection is still present, ulcers could recur or, less commonly, stomach cancer could develop. Thus, you may need to take more than one round of medicines to kill the H. pylori bacteria.

Bismuth quadruple therapy is one of several treatments used after initial treatment has failed—a strategy called “rescue” or “salvage” therapy. In the second round of treatment, the Dr. Cofranesco prescribes different antibiotics than those used in the first round. Amoxicillin, however, can be used again to treat H. pylori infection because H. pylori resistance to this antibiotic is rare.

Can antacids or milk help a peptic ulcer heal?

An antacid may make the ulcer pain go away temporarily, but it will not kill H. pylori. People being treated for an H. pylori ulcer should check with Dr. Cofrancesco or Dr. Quijano before taking antacids. Some of the antibiotics used to kill H. pylori may not work as well if combined with an antacid. People used to believe drinking milk helped peptic ulcers heal. But doctors know now that while milk may make an ulcer feel better briefly, it also increases stomach acid, which can make ulcers worse. You should talk with Dr. Cofrancesco or Dr. Quijano about drinking milk while an ulcer is healing.

Can H. pylori infection be prevented?

No one knows for sure how H. pylori spreads, so prevention is difficult. Researchers are trying to develop a vaccine to prevent—and even cure—H. pylori infection. To help prevent infection, Dr. Cofrancesco and Dr. Quijano advise people to

        • wash their hands with soap and water after using the bathroom and before eating
        • eat food that has been washed well and cooked properly
        • drink water from a clean, safe source
