Stomach ulcers

Stomach ulcers occur in the lining of your stomach. Although they are common and can be treated, it's important to be aware of the symptoms and get diagnosed early. If left untreated, stomach ulcers can lead to more serious complications.

What are stomach ulcers?

Stomach ulcers are open, inflamed sores in the lining of your stomach. They are also known as gastric ulcers. You can also get ulcers in the upper part of your small intestine – these are known as duodenal ulcers.

The most common causes of stomach ulcers are:

Spicy foods don’t cause stomach ulcers, but they can worsen the symptoms.

Stomach ulcer symptoms

Most people with a stomach ulcer don’t experience any symptoms. The most common symptom is burning pain in the upper abdomen. The pain can travel to your chest and neck, bellybutton, or back.

Other less common symptoms include:

  • indigestion (heartburn)
  • loss of appetite
  • vomiting
  • feeling full and bloated, or belching
  • not being able to tolerate fatty foods
  • nausea.

Sometimes, stomach ulcers can lead to more serious symptoms, such as:

  • a sudden sharp pain in your stomach that gets worse
  • vomiting blood
  • blood in your stool (poo) or black stools.

If you have any of these symptoms, see a doctor immediately.

How are stomach ulcers diagnosed?

Stomach ulcers are most commonly diagnosed by endoscopy – using a flexible tube with a tiny camera that’s passed into your mouth and down to your stomach. This procedure is done under general anaesthetic.

You’re also likely to have tests to check for Helicobacter pylori infection. Usually this involves a breath test, or a test of the stomach lining during endoscopy.

Stomach ulcer treatments

If you have a stomach ulcer, you may be given:

  • a combination of antibiotic medicines to kill the Helicobacter pylori bacteria if it is present
  • medicines that reduce the amount of acid your stomach produces, such as proton pump inhibitors.

Some people have one of these treatments, while some have both.

If you think you may have a stomach ulcer, see your doctor immediately.

Peptic ulcer - Lab Tests Online AU

Peptic ulcers are holes in the lining of the stomach and duodenum (upper part of the small intestine), usually caused by a bacterial infection with Helicobacter pylori (H. pylori). The stomach produces hydrochloric acid and enzymes, including pepsin, that break down and digest food. A mucus layer coats the stomach and protects it from the acid. Prostaglandins also aid in protecting the lining.
