How Serious Is a Bleeding Stomach Ulcer
A bleeding stomach ulcer can be life-threatening if left untreated

Bleeding is one of the most common complications of a stomach ulcer. Excessive or rapid bleeding from a stomach ulcer can be life-threatening. 

Severe blood loss from a bleeding ulcer can cause black or bloody vomit, tarry stools, and low blood pressure and may require urgent hospitalization and a blood transfusion.

Gradual, mild bleeding from a stomach ulcer may go unnoticed. If left untreated, however, it can cause anemia which may lead to:

Consult your doctor if you have any of the above symptoms. Untreated bleeding in the gut can cause serious consequences in the long run.

What is a stomach ulcer?

The inner lining of the stomach is made up of protective tissue called the mucosa, which protects the underlying tissues from acidic stomach contents. Any break or sore in this mucus membrane layer is called a stomach ulcer or peptic ulcer

  • Duodenal ulcers: Ulcers in the first part of the small bowel (duodenum)
  • Esophageal ulcers: Ulcers that develop in the esophagus (the tube that connects the mouth with the stomach)

What are the symptoms of a stomach ulcer?

Symptoms of a stomach ulcer vary from person to person and may range from mild to severe. However, some people may not have any symptoms, particularly in the initial stages of the disease. 

The most typical symptom of a stomach ulcer is a dull, burning pain in the upper part of the abdomen (epigastric pain). This pain particularly occurs after eating fatty or spicy foods or when the stomach is empty (between meals). It may even wake you up from sleep. The pain may last from a few minutes to a few hours and may be relieved by eating certain foods that buffer stomach acidity (such as milk or bananas) or taking antacids or acid-reducing medications.

Common symptoms of a stomach ulcer may include:

What causes stomach ulcers?

Stomach ulcers may result from any or a combination of the following factors:

  • H. pylori infection: This bacterium causes inflammation in the stomach lining leading to ulcer formation. The risk is even higher when the infection is present in people who smoke.
  • Prolonged use of nonsteroidal anti-inflammatory drugs: These include aspirin, ibuprofen, ketoprofen, and naproxen.
  • Zollinger-Ellison syndrome: Zollinger-Ellison syndrome is a rare condition that causes the formation of one or more tumors (cancerous or noncancerous) in your pancreas or duodenum. Gastrin, a hormone secreted by these tumors, causes an increase in stomach acid production and the development of ulcers. 

Other factors that may increase the risk of stomach ulcers include:


Pancreatitis is inflammation of an organ in the abdomen called the pancreas. See Answer

How is a bleeding stomach ulcer treated?

Treatment for a bleeding stomach ulcer varies depending on the severity of the bleeding. You may require a blood transfusion to make up for the blood loss. The bleeding vessel may need to be repaired through endoscopic surgery. If there is a perforation or hole in the stomach lining, urgent surgery may be required.

Your doctor may also prescribe medications and suggest lifestyle modifications. Medications may include:

  • Antibiotics to treat H. pylori infection
  • Antacids or medications that neutralize stomach acids
  • Proton pump inhibitors and H2 blockers (medications that reduce stomach acid secretion)
  • Cytoprotective agents or medications that protect the stomach lining

Lifestyle modifications may include:

  • Quitting smoking
  • Avoiding alcohol 
  • Avoiding spicy and fatty foods
  • Eating a healthy diet rich in vegetables and fruits
