A peptic ulcer is a sore in the lining of your stomach or in the first part of your small intestine (duodenum). It can cause belly (abdominal) pain and other symptoms. In some cases, a peptic ulcer may get worse. This can lead to serious problems such as bleeding or a hole (perforation) in the stomach or duodenum. Treatment is needed to prevent these complications. With treatment, most people fully recover.
Common causes of a peptic ulcer
A peptic ulcer can be caused by:
Infection from H. pylori (Helicobacter pylori) bacteria
Long-term use of pain medicines called non-steroidal anti-inflammatory drugs (NSAIDs), such as aspirin and ibuprofen
Physical stress such as burns, head injuries, needing a breathing tube, or being on blood- thinning medicine
Other rare causes
How a peptic ulcer forms
The lining of your stomach and duodenum is coated with a thick mucus layer. This helps protect the stomach and duodenum from the acids and enzymes they make to help break down the food you eat. When H. pylori is present, it can weaken the mucus layer and irritate the lining underneath. Acid may pass through the weakened mucus layer and cause an ulcer to form. Overuse of NSAIDs can also damage the mucus layer, leading to ulcers.
Symptoms of a peptic ulcer
Peptic ulcers may or may not cause symptoms. If you do have symptoms, they may come and go. They may also range from mild to severe. Common symptoms include:
Burning, cramping, or hunger-like pain in the stomach area (often 1 to 3 hours after a meal, or in the middle of the night)
Pain that gets better or worse with eating
Loss of appetite
Nausea or vomiting (vomit may be bloody or look like coffee grounds)
Black, tarry, or bloody stools (this means the ulcer is bleeding)
Diagnosing a peptic ulcer
Your healthcare provider will ask about your symptoms and health history. You’ll also have a physical exam. In addition, tests will be done to confirm the problem. These tests also help determine if an ulcer is caused by H. pylori. Tests can include:
Blood, stool, or breath tests. These are done to check for H. pylori and other problems. For blood and stool tests, small samples of your blood and stool are taken. The samples are sent to a lab for exam. For a breath test, you'll drink a liquid that contains a harmless compound. H pylori causes the compound to break down and release carbon dioxide gas. By testing the air you breathe out after you drink the liquid, the doctor can tell if the bacteria are present.
Upper endoscopy. This test is done to see inside the stomach and duodenum. This lets your provider check for ulcers. During the test, an endoscope (scope) is used. This is a thin, flexible tube with a tiny camera on the end. The scope is inserted through your mouth. It is then guided down into your stomach or duodenum. If needed, tiny tools may be passed through the scope to take tissue samples (biopsy). Treatment can also be done at the same time if bleeding or other problems are found.
Upper gastrointestinal (GI) series. This test is done to take X-rays of your upper digestive tract from your mouth to the small intestine. This lets your provider check for ulcers. For this test, you’ll drink a milky liquid that has a substance called barium. The barium coats your upper digestive tract so that it will show up clearly on X-rays.
Treating a peptic ulcer
Medicines are the most common treatment for peptic ulcers. They include:
Antibiotics. These kill H. pylori bacteria. In many cases, you’ll need to take at least 2 types of antibiotics.
Proton pump inhibitors. These block your stomach from making any acid.
H2 blockers. These reduce the amount of acid your stomach makes.
Bismuth subsalicylate. This helps protect the lining of your stomach and duodenum from acid.
Be sure to take all of the medicines that you’re prescribed exactly as instructed. Don’t stop taking the medicines, even if you are feeling better. The medicines may cause side effects. Your healthcare provider will tell you more about these based on which medicines you are prescribed. During treatment, avoid taking aspirin and other NSAIDs. You may also be told to avoid cigarettes, alcohol, and caffeine. These may worsen your symptoms or affect how well your ulcer heals. If your stress level is high, reducing stress may help.
In severe cases, other treatments will likely be done. These may include procedures with an endoscope or surgery. Your provider will tell you more about these treatments, if needed.
When to call your healthcare provider
Call your provider right away if you have any of the following:
Fever of 100.4°F (38°C) or higher, or as advised by your provider
Frequent vomiting, blood in your vomit, or coffee ground-like substance in your vomit
Sudden or severe abdominal pain
Dark, tarry, or bloody stools
Pain that doesn't get better, even with treatment
Preventing a peptic ulcer
Take the following steps to help prevent a peptic ulcer:
Reduce your risk of H. pylori infection. Most experts think that H. pylori can be passed through food or water that is contaminated by an infected person. For your safety, the CDC recommends following basic hygiene. For instance, always wash your hands with warm water and soap after using the bathroom. Also wash your hands before preparing and handling food. And only drink water from safe sources.
Limit the use of aspirin and NSAIDs. Work with your provider to change your medicine or to reduce the amount of NSAIDs you take. If you must take aspirin or NSAIDs, ask your provider about other pain medicines you can take to help protect your stomach and duodenum. Sometimes other pain medicines can be used instead. But if you take aspirin because of a heart condition, blood clot, or stroke, talk with your healthcare provider first before you stop taking aspirin.
Quit smoking. Quit other forms of tobacco too.
What is a peptic ulcer?
A peptic ulcer is a sore on the lining of your stomach or the first part of your small intestine (duodenum). If the ulcer is in your stomach, it is called a gastric ulcer. If the ulcer is in your duodenum, it is called a duodenal ulcer.
Ulcers are fairly common.
What causes peptic ulcers?
In the past, experts thought lifestyle factors such as stress and diet caused ulcers. Today we know that stomach acids and other digestive juices help create ulcers. These fluids burn the linings of your organs.
Causes of peptic ulcers include:
- H. pylori bacteria (Helicobacter pylori). Most ulcers are caused by an infection from a bacteria or germ called H. pylori. This bacteria hurts the mucus that protects the lining of your stomach and the first part of your small intestine (the duodenum). Stomach acid then gets through to the lining.
- NSAIDs (nonsteroidal anti-inflammatory drugs). These are over-the-counter pain and fever medicines such as aspirin, ibuprofen, and naproxen. Over time they can damage the mucus that protects the lining of your stomach.
What are the symptoms of peptic ulcers?
Each person’s symptoms may vary. In some cases ulcers don’t cause any symptoms.
The most common ulcer symptom is a dull or burning pain in your belly between your breastbone and your belly button (navel). This pain often occurs around meal times and may wake you up at night. It can last from a few minutes to a few hours.
Less common ulcer symptoms may include:
- Feeling full after eating a small amount of food
- Not feeling hungry
- Losing weight without trying
- Bloody or black stool
- Vomiting blood
Peptic ulcer symptoms may look like other health problems. Always see your healthcare provider to be sure.
How are peptic ulcers diagnosed?
Your healthcare provider will look at your past health and give you a physical exam. You may also have some tests.
Imaging tests used to diagnose ulcers include:
- Upper GI (gastrointestinal) series or barium swallow. This test looks at the organs of the top part of your digestive system. It checks your food pipe (esophagus), stomach, and the first part of the small intestine (the duodenum). You will swallow a metallic fluid called barium. Barium coats the organs so that they can be seen on an X-ray.
- Upper endoscopy or EGD (esophagogastroduodenoscopy). This test looks at the lining of your esophagus, stomach, and duodenum. It uses a thin lighted tube called an endoscope. The tube has a camera at one end. The tube is put into your mouth and throat. Then it goes into your esophagus, stomach, and duodenum. Your health care provider can see the inside of these organs. A small tissue sample (biopsy) can be taken. This can be checked for H. pylori.
You may also have the following lab tests to see if you have an H. pylori infection:
- Blood tests. These check for infection-fighting cells (antibodies) that mean you have H. pylori.
- Stool culture. A small sample of your stool is collected and sent to a lab. In 2 or 3 days, the test will show if you have H. pylori.
- Urea breath test. This checks to see how much carbon dioxide is in your breath when you exhale. You will swallow a urea pill that has carbon molecules. If you have H. pylori, the urea will break down and become carbon dioxide. You will have a sample taken of your breath by breathing into a bag. It will be sent to a lab. If your sample shows higher than normal amounts of carbon dioxide, you have H. pylori.
How are peptic ulcers treated?
Treatment will depend on the type of ulcer you have. Your healthcare provider will create a care plan for you based on what is causing your ulcer.
Treatment can include making lifestyle changes, taking medicines, or in some cases having surgery.
Lifestyle changes may include:
- Not eating certain foods. Avoid any foods that make your symptoms worse.
- Quitting smoking. Smoking can keep your ulcer from healing. It is also linked to ulcers coming back after treatment.
- Limiting alcohol and caffeine. They can make your symptoms worse.
- Not using NSAIDs (non-steroidal anti-inflammatory medicines). These include aspirin and ibuprofen.
Medicines to treat ulcers may include:
- Antibiotics. These bacteria-fighting medicines are used to kill the H. pylori bacteria. Often a mix of antibiotics and other medicines is used to cure the ulcer and get rid of the infection.
- H2-blockers (histamine receptor blockers). These reduce the amount of acid your stomach makes by blocking the hormone histamine. Histamine helps to make acid.
- Proton pump inhibitors or PPIs. These lower stomach acid levels and protect the lining of your stomach and duodenum.
- Mucosal protective agents. These medicines protect the stomach's mucus lining from acid damage so that it can heal.
- Antacids. These quickly weaken or neutralize stomach acid to ease your symptoms.
In most cases, medicines can heal ulcers quickly. Once the H. pylori bacteria is removed, most ulcers do not come back.
In rare cases, surgery may be needed if medicines don’t help. You may also need surgery if your ulcer causes other medical problems.
What are the complications of peptic ulcers?
Ulcers can cause serious problems if you don’t get treatment.
The most common problems include:
- Bleeding. As an ulcer wears away the muscles of the stomach or duodenal wall, blood vessels may be hurt. This causes bleeding.
- Hole (perforation). Sometimes an ulcer makes a hole in the wall of your stomach or duodenum. When this happens, bacteria and partly digested food can get in. This causes infection and redness or swelling (inflammation).
- Narrowing and blockage (obstruction). Ulcers that are found where the duodenum joins the stomach can cause swelling and scarring. This can narrow or even block the opening to the duodenum. Food can’t leave your stomach and go into your small intestine. This causes vomiting. You can’t eat properly.
When should I call my healthcare provider?
See your healthcare provider right away if you have any of these symptoms:
- Vomiting blood or dark material that looks like coffee grounds
- Extreme weakness or dizziness
- Blood in your stools (your stools may look black or like tar)
- Nausea or vomiting that doesn’t get better, or gets worse
- A sudden, severe pain that may spread to your back
- Losing weight without even trying
Untreated peptic ulcers may cause other health problems. Sometimes they bleed. If they become too deep, they can break through your stomach.
Ulcers can also keep food from going through your stomach.
- These ulcers are sores on the lining of your stomach or the first part of your small intestine (the duodenum).
- Stomach acids and other digestive juices help to make ulcers by burning the linings of these organs.
- Most ulcers are caused by infection from a bacteria or germ called H. pylori (Helicobacter pylori) or from using pain killers called NSAIDs.
- The most common symptom is a dull or burning pain in the belly between the breastbone and the belly button.
- Ulcers can be treated with a mix of lifestyle changes and medicines. In rare cases, surgery is needed.
