Understanding Perforated Ulcers

A peptic ulcer is an open sore in the stomach lining or the upper part of the small intestine (duodenum). An ulcer can go through all the layers of the digestive tract and form a hole (perforation). This is called a perforated ulcer. A perforated ulcer allows food and digestive juices to get out of the digestive tract. This is a serious health problem that needs urgent medical attention.

What causes perforated ulcers?

A hole will form if peptic ulcers go untreated. To find the cause of your ulcer, your healthcare provider will give you an exam and take your health history. He or she may also order tests. The main causes of peptic ulcers include:

  • Infection with the H. pylori (Helicobacter pylori) bacteria. This damages the stomach lining. Digestive juices can then harm the digestive tract.

  • Long-term use of some over-the-counter pain medicines. This makes stomach or intestinal damage more likely.

Symptoms of a perforated ulcer

Symptoms of a perforated ulcer may include:

  • Sudden, severe pain in the belly (abdomen)

  • Pain spreading to the back or shoulder

  • Upset stomach (nausea) or vomiting

  • Lack of appetite

  • Swollen belly

Treatment for a perforated ulcer

Treatment for a perforated ulcer starts with fixing the hole in your digestive tract. This may be done with surgery.

Other treatments are aimed at easing pain and removing the cause of the ulcer. Prescription medicines may help with the following:

  • Reducing the amount of acid the stomach makes

  • Coating the lining of the stomach and the duodenum

  • Treating infections

Your provider may also give you different medicines if your ulcer was caused by over-the-counter pain medicines. In some cases, these medicines can’t be avoided. Check with your healthcare provider to see what is best for you. 

Possible complications of a perforated ulcer

Perforated ulcers can have serious complications. These include:

  • Infection of the lining of the abdomen

  • Bloodstream infection

  • Death
