Gastric Ulcers
What is Gastric Ulcers?
Gastric ulcers are open sores that develop on the lining of your stomach. They form when the protective mucus layer breaks down and stomach acid damages the tissue beneath. These painful wounds can range from small to several centimeters wide.
Your stomach produces acid to digest food. Normally, a thick mucus layer protects your stomach walls from this acid. When this protection fails, acid eats away at the lining and creates an ulcer. Gastric ulcers are one type of peptic ulcer, which also includes ulcers in the upper part of your small intestine.
Most gastric ulcers heal with proper treatment. Without care, they can lead to serious problems like bleeding or holes in the stomach wall. The good news is that modern medicine understands the root causes and can address them directly.
Symptoms
- Burning or gnawing pain in the upper abdomen, often between meals or at night
- Nausea or vomiting
- Loss of appetite or feeling full quickly
- Bloating or belching
- Weight loss without trying
- Dark or black stools, which may indicate bleeding
- Vomiting blood or material that looks like coffee grounds
- Heartburn or acid reflux
Some people with gastric ulcers experience no symptoms at all, especially in the early stages. Others only notice mild discomfort that comes and goes. Pain often improves temporarily after eating or taking antacids.

Causes and risk factors
The two main causes of gastric ulcers are infection with Helicobacter pylori bacteria and long-term use of nonsteroidal anti-inflammatory drugs like ibuprofen or aspirin. H. pylori weakens the protective mucus layer, allowing acid to damage the stomach lining. NSAIDs reduce the production of protective substances in your stomach. Both create an environment where ulcers can form.
Other risk factors include smoking, which increases stomach acid production and slows healing. Excessive alcohol use irritates and erodes the stomach lining. Stress and spicy foods do not cause ulcers, but they can make symptoms worse. High gastrin levels can also contribute by stimulating too much stomach acid production. People over 50, those with a family history of ulcers, and individuals taking steroids or blood thinners face higher risk.
How it's diagnosed
Doctors diagnose gastric ulcers through several methods. The most common is an upper endoscopy, where a thin tube with a camera examines your stomach lining directly. During this procedure, doctors can take tissue samples to test for H. pylori bacteria. Other tests include breath tests, stool tests, or blood tests to detect H. pylori infection.
Blood tests can measure gastrin levels to check if excess stomach acid production may be contributing to ulcers. Elevated gastrin can indicate conditions like Zollinger-Ellison syndrome, which causes multiple or recurring ulcers. Your doctor may also order imaging tests like upper GI series with barium. Talk to a doctor about which tests are right for your situation and symptoms.
Treatment options
- Antibiotics to eliminate H. pylori infection if bacteria are present
- Proton pump inhibitors to reduce stomach acid production and promote healing
- H2 blockers to decrease acid production
- Antacids to neutralize existing stomach acid and provide quick relief
- Medications that protect the stomach lining
- Stopping NSAID use or switching to alternative pain relievers
- Eating smaller, more frequent meals to reduce acid buildup
- Avoiding foods that trigger symptoms or increase acid production
- Quitting smoking to improve healing and reduce recurrence
- Limiting alcohol consumption
- Managing stress through relaxation techniques and lifestyle changes
- Getting adequate sleep to support healing
Frequently asked questions
Gastric ulcers occur specifically in the stomach lining. Duodenal ulcers form in the upper part of the small intestine. Esophageal ulcers develop in the esophagus. All three are types of peptic ulcers caused by stomach acid damaging tissue.
Some small ulcers may heal temporarily without treatment, but they usually come back. Proper treatment addresses the root cause, such as H. pylori infection or NSAID use. Without treating the underlying problem, ulcers often recur and can lead to serious complications like bleeding or perforation.
Most gastric ulcers heal within 4 to 8 weeks with proper treatment. Larger ulcers or those caused by ongoing NSAID use may take longer. Your doctor may perform a follow-up endoscopy to confirm the ulcer has healed completely.
Yes, H. pylori can spread from person to person through saliva, vomit, or fecal matter. It may pass through contaminated food or water. Good hygiene, including handwashing before eating and after using the bathroom, can reduce transmission risk.
Avoid foods that increase acid production or irritate your stomach. Common triggers include spicy foods, citrus fruits, tomatoes, chocolate, caffeine, and alcohol. Fried and fatty foods can also worsen symptoms. Pay attention to your body and identify your personal triggers.
Stress does not directly cause gastric ulcers. However, it can increase stomach acid production and make existing ulcers worse. Chronic stress may also weaken your immune system, making H. pylori infection more likely to cause problems.
Gastrin is a hormone that signals your stomach to produce acid for digestion. High gastrin levels can lead to excess acid production, which damages the stomach lining. Testing gastrin levels helps identify if overproduction of stomach acid is contributing to ulcer formation.
See a doctor immediately if you have severe abdominal pain, bloody or black stools, or vomit blood. Also seek care for persistent stomach pain lasting more than a few days, unexplained weight loss, or difficulty swallowing. Early diagnosis prevents serious complications.
Talk to your doctor before taking any pain medication. If you need pain relief, acetaminophen is usually safer than NSAIDs for people with ulcer history. If NSAIDs are necessary, your doctor may prescribe protective medications to take alongside them.
H. pylori infection, which causes most ulcers, increases stomach cancer risk over time. However, most people with ulcers never develop cancer. Treating H. pylori infection and monitoring ulcers with endoscopy helps reduce this risk significantly.
