Peptic Ulcer

Explore the available health information, treatment context, and integrative evidence for Peptic Ulcer.

Background
  • A peptic ulcer is a sore in the lining of the stomach, esophagus, or the first portion of the small intestine. Peptic ulcers may also be referred to as an ulcer.
  • Ulcers are crater-like sores, generally one-fourth to three-fourths inch in diameter, but sometimes one to two inches in diameter. Ulcers that form in the lining of the stomach are called gastric ulcers. Ulcers that form just below the stomach at the beginning of the small intestine in the duodenum are called duodenal ulcers. Less common ulcers occur in the esophagus and are called esophageal ulcers.
  • A burning stomach pain is the most common symptom of an ulcer. The pain may come and go for a few days or weeks or may bother the individual more when the stomach is empty. The pain usually goes away after eating, but may return when the stomach becomes empty again.
  • Peptic ulcers occur when the digestive juices that help food digest damage the walls of the stomach or duodenum. The most common cause is infection with a bacterium called Helicobacter pylori, or H. pylori. Another cause is the long-term use of nonsteroidal anti-inflammatory drugs (NSAIDs) such as aspirin and ibuprofen (Motrin® or Advil®). Spicy foods do not cause ulcers, but can aggravate them and make them worse.
  • Peptic ulcers will become more severe if not treated. Treatment may include medicines to block stomach acids or antibiotics to kill ulcer-causing bacteria. Avoiding smoking and alcohol can help decrease symptoms of ulcers. Surgery may help for ulcers that do not heal. Peptic ulcers may also heal on their own without treatment.
  • The American College of Gastroenterology estimates that about 20 million Americans develop at least one ulcer during their lifetime.
  • Although ulcers may cause discomfort, they are rarely life threatening. By understanding the causes and symptoms of ulcers and getting a diagnosis and proper treatment, most people can find relief.
  • The names given to specific ulcers identify their location in the digestive tract or the circumstances under which they develop. Duodenal ulcers, the most common type of peptic ulcer, occur in the first few inches of the duodenum. The duodenum is the first portion of the small intestine. Gastric ulcers, which are less common, usually occur along the upper curve of the stomach. Marginal ulcers can develop when part of the stomach has been removed surgically at the point where the remaining stomach has been reconnected to the intestine. Stress ulcers, like acute stress gastritis, can occur as a result of the stress of severe illness, skin burns, or trauma. Stress ulcers occur in the stomach and the duodenum. An esophageal ulcer is usually located in the lower section of the esophagus. Esophageal varices (veins) are dilated blood vessels within the wall of the esophagus and may have similar symptoms of esophageal ulcers such as burning.
  • Individuals with gastroesophageal reflux disease (GERD) are at an increased risk for developing ulcers. GERD occurs when the lower esophageal sphincter (the valve separating the esophagus and stomach) does not close properly, allowing acid to back up into the esophagus.
Risk Factors and Causes
  • Infection: Although stress and spicy foods were once thought to be the main causes of peptic ulcers, doctors now know that the cause of most ulcers is the corkscrew-shaped bacterium Helicobacter pylori (H. pylori). H. pylori lives and multiplies within the mucous layer that covers and protects tissues that line the digestive tract. H. pylori usually does not cause problems, but sometimes the bacteria can disrupt the mucous layer and inflame the lining of the stomach or duodenum, producing an ulcer. Individuals who develop peptic ulcers may already have damage to the lining of the stomach or small intestine, making it easier for bacteria to invade and inflame tissues. H. pylori is a common digestive tract infection around the world. In the United States, one in five people younger than 30 and half the people older than 60 are infected with H. pylori. Although it's not clear exactly how H. pylori spreads, the bacteria may be transmitted from person to person by close contact, such as kissing. Individuals may also contract H. pylori through food and water. H. pylori is the most common, but not the only, cause of peptic ulcers.
  • Pain relievers: Pain-relieving drugs called non-steroidal anti-inflammatory drugs (NSAIDs) can irritate or inflame the lining of the stomach and small intestine. The medications are available both by prescription and over-the-counter. Nonprescription NSAIDs include aspirin, ibuprofen (Advil®, Motrin®), naproxen (Aleve®), and ketoprofen (Orudis KT®). Individuals vary in sensitivity to these medications. Some individuals may develop ulcer symptoms with occasional use of NSAIDs, others with long-term. To help avoid digestive upset, take NSAIDs with food. NSAIDs inhibit production of an enzyme that produces hormone-like substances called prostaglandins. Prostaglandins help protect the stomach lining from chemical and physical injury. Without this protection, stomach acid can erode the lining causing bleeding and ulcers.
  • Smoking and Caffeine: Individuals who smoke and those exposed to second hang smoke have an increased risk of developing an ulcer. Smoking may also slow healing during ulcer treatment. Caffeine stimulates acid secretion in the stomach, thus aggravating the pain of an existing ulcer. Drinking coffee or tea daily may also increase the chances of developing a peptic ulcer.
  • Excessive alcohol consumption: Alcohol can irritate and erode the mucous lining of the stomach and it increases the amount of stomach acid that is produced. It is uncertain, however, whether alcohol consumption alone can cause an ulcer or whether other contributing factors must be present, such as H. pylori bacteria or ulcer-causing medications.
  • Stress: Although stress is not a direct cause of peptic ulcers, it is a contributing risk factor. Stress may aggravate symptoms of peptic ulcers and, in some cases, delay healing. Stress can be caused by a number of reasons, including emotionally disturbing circumstances or events, surgery, or a physical injury, such as a severe burn. Stress ulcers can occur as a result of the stress of severe illness, skin burns, or trauma. Stress ulcers occur in the stomach and the duodenum.
  • Other conditions: Achalasia is a rare disease of a muscle of the esophagus, the body's swallowing tube. The term achalasia means "failure to relax" and refers to the inability of a ring of muscle between the lower esophagus and the stomach called the esophageal sphincter to open and let food pass into the stomach. As a result, patients with achalasia have difficulty swallowing food. Gastroesophageal reflux disease (GERD) can develop as a result.
Signs and Symptoms
  • Burning pain is the most common peptic ulcer symptom. The pain is caused by the ulcer and is aggravated by stomach acid coming in contact with the ulcerated area. The pain typically may be felt anywhere from the navel to the breastbone. The pain may last from a few minutes to many hours and may flare up a night. Peptic ulcers also tend to be worse when the stomach is empty. Ulcers are often temporarily relieved by eating certain foods that buffer stomach acid, such as milk, or by taking acid-reducing medications, such as calcium carbonate (Tums®). Burning pain may come and go for a few days or weeks. Ulcer pain may also return after years of absence.
  • Less often, ulcers may cause severe signs or symptoms, such as the vomiting of blood (which may appear red or black) and dark blood in stools or stools that are black or tarry. Other severe signs of an ulcer include nausea or vomiting, unexplained weight loss, and chest pain.
  • An ulcer is not generally something that should be treated at home. A doctor can help with prescribed medications or advise the individual the over-the-counter (OTC) medications that may be best. OTC antacids and acid blockers may relieve the burning pain, but the relief is usually temporary. When signs or symptoms of a peptic ulcer exist, a doctor should perform a physical examination to determine if a peptic ulcer exists.
Diagnosis
  • Upper gastrointestinal (upper GI) X-ray: If an individual has signs and symptoms of a peptic ulcer, the doctor may begin with an upper gastrointestinal x-ray, also known as an upper GI. An upper GI allows the doctor to visualize the esophagus, stomach, and duodenum. During the x-ray, the individual swallows a white, metallic liquid (containing barium) that coats the digestive tract and makes an ulcer more visible. An upper GI x-ray can detect some ulcers, but not all.
  • Endoscopy: An endoscopy may follow an upper GI X-ray if the x-ray suggests a possible ulcer. Doctors also may use the endoscopy as the first choice of diagnosis. In this more sensitive procedure, a long, narrow tube with a small attached camera is threaded down the throat and esophagus into the stomach and duodenum. With this instrument, the doctor can view the upper digestive tract and identify an ulcer. If the doctor detects an ulcer, they may remove small tissue samples near the ulcer. These samples are examined under a microscope to rule out cancer. A biopsy can also identify the presence of H. pylori in the stomach lining by using laboratory tests. Depending on where the ulcer is found, the doctor may recommend a repeat endoscopy after two to three months to confirm that the ulcer is healing. Possible complications of upper endoscopy include bleeding and puncture of the stomach lining. However, such complications are rare. Most people will probably have nothing more than a mild sore throat after the procedure. The procedure takes 20-30 minutes. Because the individual will be sedated, they will need to rest at the endoscopy facility for one to two hours until the medication wears off. It is recommended to have a friend or loved one drive.
  • Blood test: A blood test can check for the presence of H. pylori antibodies. The body's immune system produces antibodies specific for H. pylori when the bacteria exists in the body. A disadvantage of this test is that it sometimes cannot determine if the antibodies are from a past exposure to H. Pylori bacteria or a current infection. After H. pylori bacteria have been destroyed, the individual may still have a positive test result for many months.
  • Breath test: A breath test uses a harmless radioactive carbon atom to detect H. pylori. First, the individual blows into a small plastic bag, which is then sealed. Then, the person drinks a small glass of clear, tasteless liquid. The liquid contains radioactive carbon mixed with urea. This combination will be broken down by H. pylori if it is present in the body. Thirty minutes later, the person blows into a second bag, which is then also sealed. If the individual is infected with H. pylori, the second breath sample will contain the radioactive carbon in the form of carbon dioxide.
  • The advantage of the breath test is that it can monitor the effectiveness of treatment, such as antibiotics, used to eradicate H. pylori, detecting when the bacteria have been killed. With the blood test, H. pylori antibodies may sometimes still be present a year or more after the infection is gone.
  • Stool antigen test: The stool antigen test checks for H. pylori in stool samples. This test is useful both in helping to diagnose H. pylori infection and in monitoring the success of treatment.
Complications
  • Most ulcers can be cured without complications. However, in some rare cases, peptic ulcers can develop potentially life-threatening complications, such as penetration, perforation (holes), bleeding (hemorrhage), and obstruction. Depending upon the individual, life-threatening complications usually develop over time.
  • Penetration: An ulcer can penetrate (go through) the muscular wall of the stomach or duodenum and continue into a nearby organ, such as the liver or pancreas. This penetration causes an intense, piercing, persistent pain, which may be felt outside of the area involved. Sometimes the back may hurt when a duodenal ulcer penetrates the pancreas. The pain may intensify when the person changes position. If drugs do not heal the ulcer, surgery may be needed.
  • Perforation: Ulcers on the front surface of the duodenum, or less commonly the stomach, can perforate or go through the wall of the organ. Perforating ulcers create an opening to the free space in the abdominal cavity. The pain resulting from this perforation is sudden, intense, and steady, and rapidly spreads throughout the abdomen. The individual may also feel pain in one or both shoulders, which may intensify with deep breathing. Changing position worsens the pain, so the person often tries to lie very still. The abdomen is tender when touched, and the tenderness worsens if a doctor presses deeply and then suddenly releases the pressure. Symptoms may be less intense in older individuals, in individuals taking corticosteroids, or in very ill individuals. A fever indicates an infection in the abdomen. If the condition is not treated, shock may develop. This emergency situation requires immediate surgery and intravenous (IV) antibiotics.
  • Hemorrhage: Hemorrhage (bleeding) is a common complication of ulcers, even when they are not painful. Symptoms of a bleeding ulcer may include vomiting bright red blood or reddish brown clumps of partially digested blood that look like coffee grounds. Small amounts of blood in the stool may not be noticeable but, if persistent, can still lead to anemia, or the deficiency of hemoglobin (the oxygen-carrying component of the blood). Bleeding may result from other digestive conditions as well, but doctors begin their investigation by looking for the source of bleeding in the stomach and duodenum. Unless bleeding is massive, a doctor performs a procedure called an endoscopy. An endoscopy is an examination using a flexible viewing tube. If a bleeding ulcer is seen, the endoscope can be used to cauterize, which is the use of heat to close the bleeding opening. A doctor may also use the endoscope to inject a material that causes a bleeding ulcer to clot. If the source cannot be found and the bleeding is not severe, treatments include taking ulcer drugs, such as cimetidine (Tagamet®) or omeprazole (Prilosec®). The individual also receives intravenous (IV) fluids and takes nothing by mouth, so the digestive tract can rest. If these measures fail, surgery is needed.
  • Obstruction: Swelling of inflamed tissues around an ulcer or scarring from previous ulcer flare-ups can narrow some parts of the duodenum. An individual with this type of obstruction may vomit repeatedly, often regurgitating large volumes of food eaten hours earlier. A feeling of being unusually full after eating, being bloated, and a lack of appetite are symptoms of obstruction. Over time, vomiting may cause weight loss and dehydration. Treating the ulcers relieves the obstruction in most cases, but severe obstructions may require endoscopy or surgery.
  • Enteritis: Enteritis is an inflammation of the small intestine caused by a bacterial or viral infection. H. pylori infections can cause enteritis with symptoms including gas, bloating, and pain.
  • Zollinger-Ellison syndrome: Zollinger-Ellison syndrome (ZES) is a rare disorder that causes tumors in the pancreas and duodenum. ZES may also cause ulcers in the stomach and duodenum. The pancreas is a gland located behind the stomach. It produces enzymes that break down fat, protein, and carbohydrates from food and hormones such as insulin that break down sugar. The duodenum is the first part of the small intestine. ZES can occur sporadically or may be genetic. The tumors secrete a hormone called gastrin that causes the stomach to produce too much acid, which in turn causes peptic ulcers in the stomach and duodenum. The ulcers caused by ZES are less responsive to treatment than ordinary peptic ulcers. What causes people with ZES to develop tumors is unknown, but approximately 25% of ZES cases are associated with a genetic disorder called multiple endocrine neoplasia type 1. The symptoms of ZES include signs of peptic ulcers, including gnawing, burning pain in the abdomen, diarrhea, nausea, vomiting, fatigue (extreme tiredness), weakness, weight loss, and bleeding. Doctors diagnose ZES through blood tests to measure levels of gastrin and gastric acid secretion. They may check for ulcers by performing an endoscopy, which involves looking at the lining of the stomach and duodenum through a lighted tube.
  • Cancer: Individuals with ulcers caused by H. pylori have three to six times the chance of developing stomach cancer later in life. There is no increased risk of developing cancer from ulcers that have other causes. Some evidence also links H. pylori infection to gastric cancer, gastric mucosa-associated lymphoid tissue (MALT) lymphoma, and perhaps pancreatic cancer and cardiovascular disease.
Treatment
  • Because many ulcers stem from H. pylori bacteria, doctors use an approach to peptic ulcer treatment that kills or eradicates the bacteria and reduces the level of acid in the digestive system. The result of the treatment is pain relief and ulcer healing.
  • Antibiotic medications: Doctors use combinations of antibiotics to treat H. pylori infections because one antibiotic alone is not usually sufficient to kill the organism. For the treatment to work, it is essential that the individual follows the doctor's instructions on the medicine bottle precisely. Antibiotics commonly prescribed for treatment of H. pylori include amoxicillin (Amoxil®), clarithromycin (Biaxin®), and metronidazole (Flagyl®). Some companies package a combination of two antibiotics together, with an acid suppressor or cytoprotective agent specifically for treatment of H. pylori infection. These combination treatments are sold under the names Prevpac® and Helidac®. The individual will likely need to take antibiotics for two weeks, depending on the type prescribed. Antibiotics may cause diarrhea and upset the balance of natural bacteria (including Lactobacillus acidophilus) in the gastrointestinal tract. A healthcare provider may recommend taking probiotic supplements after treatment with antibiotics.
  • Acid blockers: Acid blockers, also called histamine or H2 blockers, reduce the amount of hydrochloric acid released into the digestive tract. This decrease in acid helps relieve ulcer pain and encourages healing. Acid blockers work by keeping histamine from reaching histamine receptors. Histamine is a substance normally present in the body. When it reacts with histamine receptors, the receptors signal acid-secreting cells in the stomach to release hydrochloric acid. Available by prescription or over-the-counter (OTC), acid blockers include the medications ranitidine (Zantac®), famotidine (Pepcid®), cimetidine (Tagamet®), and nizatidine (Axid®).
  • Antacids: A doctor may include an antacid in the drug therapy. An antacid may be taken in addition to an acid blocker or in place of one. Instead of reducing acid secretion, antacids neutralize existing stomach acid and can provide rapid pain relief. Antacids include calcium carbonate (Tums®, Titralac®), aluminum hydroxide and magnesium hydroxide combinations (Mylanta®, Maalox®), and aluminum hydroxide alone (Alternagel®). Antacids should be taken one hour before or two hours after taking other prescribed medications.
  • Proton pump inhibitors: Another way to reduce stomach acid is to shut down the "pumps" within acid-secreting cells. Proton pump inhibitors reduce acid by blocking the action of these tiny pumps. These drugs include the prescription medications omeprazole (Prilosec®), lansoprazole (Prevacid®), rabeprazole (Aciphex®), and esomeprazole (Nexium®). The drug pantoprozole (Protonix®) can be taken orally or administered intravenously (IV) in the hospital. Proton pump inhibitors are frequently prescribed to promote the healing of peptic ulcers. Proton pump inhibitors also appear to inhibit H. pylori. However, long-term use of proton pump inhibitors, particularly at high doses, may increase the risk of hip fracture. The risk was 2.6 times higher for long-term users of proton pump inhibitors at high doses.
  • Cytoprotective agents: In some cases, the doctor may prescribe cytoprotective medications that help protect the tissues that line the stomach and small intestine. They include the prescription medications sucralfate (Carafate®) and misoprostol (Cytotec®). Another non-prescription cytoprotective agent is bismuth subsalicylate (Pepto-Bismol®). In addition to protecting the lining of the stomach and intestines, bismuth preparations appear to inhibit H. pylori activity.
Prevention
  • Smoking: Smoking may interfere with the protective lining of the stomach making the stomach more susceptible to the development of an ulcer. Smoking also increases stomach acid. Stopping smoking may help reduce the symptoms and causes of peptic ulcers.
  • Alcohol: Excessive use of alcohol can irritate and erode the mucous lining in the stomach and intestines, causing inflammation and bleeding. Decreasing consumption of alcohol may help reduce the symptoms and causes of peptic ulcers.
  • Nonsteroidal anti-inflammatory drugs (NSAIDs): If pain relievers are used regularly, such as aspirin or nonsteroidal anti-inflammatory drugs (including ibuprofen or Advil®), acetaminophen (Tylenol®) can be used instead. Acetaminophen may offer pain relief without damaging the gastrointestinal lining, which results in ulcers.
  • Acid reflux: Controlling acid reflux, if an esophageal ulcer is present, is important. Several steps to help manage acid reflux can be taken including avoiding spicy and fatty foods, avoiding reclining after meals for at least three hours, raising the head of the bed, and reducing weight. Avoiding smoking, alcohol, and NSAIDs also may help to control acid reflux.
  • Diet: Some individuals with peptic ulcers can eat whatever they want with no problems. For many others, however, eating certain foods can cause irritation, excessive acid production, and heartburn. These individuals need to know what foods are safe and what foods to avoid. It is recommended by healthcare professionals that individuals with an ulcer make dietary changes, including eating more whole grains, fresh fruits and vegetables and less red meats and fatty foods, such as fried foods and baked goods. It is best to avoid spicy foods.
