Zwölffingerdarmgeschwür

A duodenal ulcer is usually caused by an infection with a germ (bacterium) called Helicobacter pylori (H. pylori). A 4- to 8-week course of acid-suppressing medication will allow the ulcer to heal. In addition, a one-week course of two antibiotics plus an acid-suppressing medicine will usually clear the H. pylori infection. This usually prevents the ulcer from coming back. Anti-inflammatory medicines used to treat conditions such as arthritis sometimes cause duodenal ulcers. It would be very unusual for a person with a known duodenal ulcer to be given anti-inflammatory medication, but if there is absolutely no alternative then it may be given with long-term acid-suppressing medication.

Auf einen Blick

  • A duodenal ulcer is a sore in the lining of the small intestine just beyond the stomach.

  • Most duodenal ulcers are caused by H. pylori infection or anti-inflammatory medicines.

  • Common symptoms include upper tummy pain, bloating, and feeling sick.

  • You may also feel particularly full after a meal.

  • A gastroscopy can confirm a duodenal ulcer.

  • Treatment involves addressing the cause and reducing stomach acid.

  • Seek urgent medical help if you have sudden severe tummy pain.

What is a duodenal ulcer?

A duodenal ulcer is an ulcer that occurs in the lining in the part of the small intestine just beyond the stomach (the duodenum). An ulcer in the lining of the stomach is called a gastric ulcer. The term 'peptic ulcer' is an umbrella term which includes both gastric and duodenal ulcers.

There are separate leaflets called Non-ulcer Dyspepsia (Functional Dyspepsia), Magengeschwür (Gastrisches Geschwür) und Säure-Reflux und Ösophagitis.

How do duodenal ulcers form?

Duodenal ulcers form when there is a break in the lining (epithelium) of the duodenum (part of the small intestine within the digestive system).

What causes duodenal ulcers?

There is normally a balance between the amount of acid that you make and the mucous defence barrier. An ulcer may develop if there is an alteration in this balance, allowing the acid to damage the lining of the stomach or duodenum. Causes of peptic ulcers include the following:

Infection with H. pylori

Infektion mit H. pylori bacteria is the cause in about 19 in 20 cases of duodenal ulcer. More than 1 in 4 people in the UK become infected with H. pylori at some stage in their lives. See the separate leaflet called Helicobacter Pylori for more information.

Anti-inflammatory medicines - including aspirin

Entzündungshemmende Medikamente are sometimes called non-steroidal anti-inflammatory drugs (NSAIDs). These medicines sometimes affect the mucous barrier of the duodenum and allow acid to cause an ulcer.

Other causes and factors

Other causes are rare. For example, the Zollinger-Ellison syndrome. In this rare condition, much more acid than usual is made by the stomach.

Other factors such as rauchen, stress and drinking heavily may possibly increase the risk of having a duodenal ulcer. However, these are not usually the underlying cause of duodenal ulcers.

Duodenal ulcer symptoms

  • Schmerzen in the upper tummy (abdomen) just below the breastbone (sternum) is the common symptom. It usually comes and goes. It may occur most before meals, or when you are hungry. It may be eased if you eat food, or take antacid tablets. The pain may wake you from sleep.

  • Andere Symptome which may occur include Blähungen, retching and feeling sick. You may feel particularly full after a meal. Sometimes food makes the pain worse.

  • Komplikationen occur in some cases and can be serious. These include:

    • Bleeding ulcer. This can range from a trickle to a life-threatening bleed.

    • Perforation. The ulcer goes right through (perforates) the wall of the first part of the small intestine (duodenum). Food and acid in the duodenum then leak into the abdominal cavity. This usually causes severe pain and is a medical emergency requiring surgery.

What are the treatments for a duodenal ulcer?

Allgemeine Ratschläge

Lifestyle measures can improve symptoms, such as:

Medikamente zur Magensäurehemmung

The most commonly used medicine is a proton pump inhibitor (PPI) to reduce the amount of acid in your stomach. Siehe die separate Broschüre mit dem Titel Verdauungsmedikamente für weitere Informationen.

Hinweis: there have been studies recently questioning whether long-term PPI use may have an association with stomach cancer. As more research needs to be carried out, current advice is that PPIs should be taken at the lowest dose and for the shortest length of time. You may find you are able to take PPIs just occasionally rather than daily. However, if you find that other medicines haven't helped and you have symptoms which are persisting, you are currently advised to carry on taking your PPI medication until advised otherwise by your doctor.

If your ulcer was caused by H. pylori

Nearly all duodenal ulcers are caused by infection with H. pylori. See the separate leaflet called Helicobacter Pylori for more information.

If your ulcer was caused by an anti-inflammatory medicine

If possible, you should stop the anti-inflammatory medicine. This allows the ulcer to heal. You will also normally be prescribed an acid-suppressing medicine for several weeks (see above).

Operation

Surgery is now usually only needed if a complication of a duodenal ulcer develops, such as severe bleeding or a hole (perforation).

Are duodenal ulcers dangerous?

Yes - they can be if they burst (perforate) - this needs emergency surgery and can be life-threatening.

Häufig gestellte Fragen

Are duodenal ulcers painful?

Yes, pain in the upper tummy (abdomen) just below the breastbone is a common symptom. This pain tends to come and go and may be most noticeable before meals or when you are hungry. Eating food or taking antacid tablets can sometimes ease the pain, which may even be severe enough to wake you from sleep.

Can duodenal ulcers cause constipation?

The article mentions other possible symptoms such as bloating, retching, and feeling sick, as well as feeling particularly full after a meal. However, constipation is not listed as a direct symptom or complication of a duodenal ulcer in the information provided.

Do duodenal ulcers heal?

Yes, duodenal ulcers can heal, particularly with treatment. If the ulcer is caused by H. pylori infection, targeted treatment can eradicate the bacteria. If it's due to anti-inflammatory medicines, stopping these medications often allows the ulcer to heal. Acid-suppressing medicines are also commonly prescribed to aid healing by reducing stomach acid.

What is a duodenum?

The duodenum is the first part of the small intestine, located just beyond the stomach. It's where a duodenal ulcer forms when there's a break in its lining.

What is the most common cause of duodenal ulcer?

Infection with H. pylori bacteria is the most common cause of duodenal ulcers, accounting for approximately 19 out of 20 cases.
