Key Takeaways
Gastric ulcers are painful sores that form on the inner lining of the stomach
Most ulcers are caused by H. pylori bacteria or long-term use of NSAIDs
Burning or gnawing upper-abdominal pain is a common symptom, but the timing of pain in relation to meals varies and some people have no symptoms.
Treatment typically involves antibiotics for H. pylori or acid-reducing medications
With proper treatment, most gastric ulcers heal completely within 4-8 weeks
Overview
A gastric ulcer is an open sore that develops on the inner lining of your stomach. These painful wounds form when stomach acid and digestive juices damage the protective mucus layer. Gastric ulcers are one type of peptic ulcer, which can occur in your stomach or the upper part of your small intestine.
About 4 million Americans develop peptic ulcers each year. Gastric ulcers affect people of all ages but are most common in adults over 40. Men and women get ulcers at similar rates. Without treatment, ulcers can cause serious complications like bleeding or perforation.
The good news is that gastric ulcers are very treatable. Once doctors identify the cause, most ulcers heal completely with medication. Understanding the symptoms and causes helps you get treatment early and prevent complications. Your stomach has a special lining that protects it from acid, but when this protection breaks down, ulcers can form. Early detection and treatment mean you can feel better faster and avoid serious problems.
Symptoms & Signs
Gastric ulcer symptoms can range from mild discomfort to severe pain. The intensity often depends on the size and location of the ulcer. Some people have no symptoms at all, especially in the early stages. It's important to pay attention to how your stomach feels over time. Changes in your symptoms can tell you important things about your health.
Primary Symptoms
Burning stomach pain - Usually occurs between meals or at night when your stomach is empty
Nausea and vomiting - May include blood that looks like coffee grounds
Loss of appetite - Food may seem unappealing or cause discomfort
Bloating and feeling full - Even after eating small amounts of food
When to Seek Care
Watch for signs of bleeding like black, tarry stools or vomit that contains blood. Severe, sudden stomach pain could mean the ulcer has created a hole in your stomach wall. If you experience these symptoms, you need immediate medical care. Dizziness or feeling faint along with stomach pain is also a warning sign. Learn more about when to go to the ER for stomach pain.
When to Seek Immediate Care
Contact your doctor if you have persistent stomach pain, especially if it interferes with sleep or daily activities.
Causes & Risk Factors
Most gastric ulcers have two main causes. Understanding these causes helps doctors choose the right treatment approach for your specific situation. Knowing what caused your ulcer helps prevent it from happening again in the future.
Age
Adults over 40 have higher risk, especially those over 60
Genetics
Family history of ulcers increases your likelihood
Lifestyle
Smoking, excessive alcohol, and high stress levels
Other Conditions
Zollinger-Ellison syndrome, Crohn's disease, liver disease

Diagnosis
Getting an accurate diagnosis is the first step toward healing your gastric ulcer. Your doctor will use several methods to confirm the presence of an ulcer and identify its cause.
Medical History & Physical Examination
Your doctor will ask about your symptoms, including when pain occurs and what makes it better or worse. They'll review your medications, especially any NSAIDs you take regularly. During the physical exam, your doctor will gently press on your abdomen to check for tenderness or swelling. They'll also listen to your stomach with a stethoscope.
Diagnostic Testing
Blood tests may check for anemia from bleeding. Tests for active H. pylori infection commonly include a breath test, stool test, or testing a biopsy sample during endoscopy.
Stool tests - Look for H. pylori bacteria and hidden blood
Upper endoscopy - A thin, flexible tube with a camera examines your stomach lining directly
Upper GI series - You drink a chalky liquid before X-rays to highlight ulcers
CT scan - May be used if complications like perforation are suspected

Treatment Options
Treatment focuses on healing the ulcer and preventing it from coming back. The approach depends on what caused your ulcer in the first place. Your doctor will create a treatment plan just for your specific situation based on test results.
Conservative Treatments
Proton pump inhibitors (PPIs) - Reduce stomach acid production to allow healing
H2 receptor blockers - Another type of acid-reducing medication
Antacids - Provide temporary relief by neutralizing existing stomach acid
Antibiotics - Kill H. pylori bacteria when present, usually a combination of two or three drugs
Advanced Treatments
Surgery - Rarely needed, only for complications like bleeding that won't stop or perforation
Endoscopic therapy - Uses special tools during endoscopy to stop bleeding ulcers
Most people respond well to medication within the first few weeks of treatment. Your doctor will want to see you again after a few weeks to make sure the ulcer is healing properly. It's very important to take all medications as prescribed, even if you feel better before finishing the course.
Living with the Condition
Managing a gastric ulcer involves both medical treatment and lifestyle changes. These strategies help your ulcer heal faster and prevent future problems. Small daily choices add up to make a big difference in your recovery.
Daily Management Strategies
Take medications exactly as prescribed, even if you start feeling better. Eat smaller, more frequent meals to avoid overwhelming your stomach. Avoid foods that trigger your symptoms, which often include spicy, acidic, or fried foods. If you experience nausea, consider learning about what foods help with nausea. Stay hydrated, as dehydration can cause stomach pain and worsen symptoms. Keep a food diary to track which foods make your pain better or worse.
Exercise & Movement
Gentle exercise like walking can help reduce stress and improve digestion. Avoid intense physical activity immediately after eating. Stress-reduction techniques and adequate sleep may support overall well-being and help some people manage symptoms, but they do not replace treatment for H. pylori infection or NSAID-related ulcers. Try to eat meals at the same time each day to help your stomach prepare for food.
Prevention
Stop smoking, as tobacco increases stomach acid and slows ulcer healing
Limit alcohol consumption, which can irritate your stomach lining
Avoid NSAIDs unless a clinician says they are appropriate. Taking them with food may reduce stomach upset but does not prevent ulcers; ask your clinician about safer options or protective treatment if you need an NSAID.
Manage stress through regular exercise, adequate sleep, and relaxation techniques
Practice good hygiene to reduce H. pylori transmission risk
Wash your hands frequently and use clean drinking water to avoid H. pylori bacteria
If someone in your family has had an ulcer or H. pylori, talk to your doctor about testing
Frequently Asked Questions
Small ulcers might improve with dietary changes, but most need medical treatment. Without proper treatment, ulcers often get worse and can cause serious complications like bleeding or perforation.
Most ulcers heal within 4-8 weeks with proper treatment. H. pylori treatment usually includes a short course of combination antibiotics plus acid-reducing medicine. Your clinician will tell you how long to continue each medicine and may arrange testing to confirm the infection is gone.
No, gastric ulcers are benign sores while stomach cancer involves malignant cells. However, some stomach cancers can look like ulcers, which is why your doctor may take a tissue sample during diagnosis.
Spicy foods and coffee don't directly cause ulcers, but they can worsen symptoms. The main causes are H. pylori bacteria and NSAID medications, not specific foods.
With proper treatment, especially for H. pylori infections, recurrence is uncommon. However, continuing to use NSAIDs or smoking increases your risk of developing new ulcers.
