You keep getting a gnawing, burning ache in your upper belly, and you're starting to wonder if it's something more than indigestion. A stomach ulcer is a real possibility, and the good news is that ulcers are very treatable once they're identified. Knowing the symptoms helps you decide when to wait it out and when to call a clinician.
Here's the catch: some people have textbook ulcer pain, while others feel almost nothing until a complication forces the issue. This guide walks through what stomach ulcer symptoms actually feel like, what causes them, and the warning signs that mean you should get care right away.
What is a stomach ulcer?
A stomach ulcer, also called a gastric ulcer, is an open sore on the inner lining of the stomach. It belongs to a group of conditions called peptic ulcer disease, which also includes duodenal ulcers in the first part of the small intestine. These sores form when the protective lining that shields your gut from stomach acid is worn down or damaged.
Peptic ulcers are common over a lifetime. The lifetime prevalence of peptic ulcer disease in the general population is roughly 10%, though the number of new cases each year is much smaller, at about 0.1% to 0.2%. Thanks to better treatment, ulcers are diagnosed and resolved far more often than in past decades.
What are the symptoms of a stomach ulcer?
The most common symptom of a stomach ulcer is a dull or burning pain in the upper abdomen. Per the Mayo Clinic, this pain often feels worse when the stomach is empty. The discomfort tends to come and go over time rather than staying constant.
Beyond the classic pain, ulcers can cause a range of digestive symptoms. Importantly, many people with peptic ulcers have no symptoms at all and may not notice anything until a complication develops, so a quiet stomach does not always mean a healthy one.
- Dull or burning pain in the upper abdomen, often worse on an empty stomach
- Feeling full too soon, or uncomfortably full after a meal
- Nausea or an upset stomach
- Bloating and frequent burping or belching
- Loss of appetite, and sometimes unintended weight loss
What causes stomach ulcers?
Two causes drive most ulcers. The first is a bacterial infection called Helicobacter pylori (H. pylori), which damages the stomach lining. H. pylori infection is present in roughly 42% of patients with peptic ulcer disease, and it is responsible for approximately 90% of duodenal ulcers and 70% to 90% of gastric ulcers.
The second major cause is regular use of pain relievers known as NSAIDs, such as aspirin and ibuprofen. Aspirin or NSAID use is an etiologic factor in about 36% of peptic ulcer cases. These medications can wear down the stomach's protective barrier, especially with frequent or long-term use. If you take these regularly and have ulcer-like symptoms, mention it to your clinician.
Does the timing of the pain matter?
It can. The timing of pain sometimes hints at where an ulcer sits. Duodenal ulcer pain typically comes on about 2 to 5 hours after meals, when the stomach is empty, and may even wake you at night. Gastric (stomach) ulcer pain, by contrast, often occurs promptly after eating.
These patterns are clues, not a diagnosis. Plenty of people don't fit them neatly, and only testing, such as an endoscopy or an H. pylori test, can confirm an ulcer and pinpoint its location. Use the timing as one piece of information to share with your clinician rather than a way to self-diagnose.
When should you see a doctor?
Persistent or recurring upper-belly pain, especially with nausea, bloating, or early fullness, is worth a medical visit even if it feels manageable. Ulcers usually respond well to treatment, and getting tested for H. pylori or reviewing your pain-reliever use can resolve the problem and prevent complications.
Some symptoms are emergencies. The signs below can mean an ulcer is bleeding or has perforated the stomach wall, and they require immediate care. Do not wait to see if they pass.
- Black or tarry stools, or visible blood in your stool
- Vomiting blood, or vomit that looks like coffee grounds
- Sudden, sharp, severe abdominal pain
- Feeling faint, dizzy, or short of breath alongside any of the above
How are stomach ulcers treated?
Treatment targets the cause. If H. pylori is found, clinicians treat it with a course of antibiotics combined with acid-reducing medication. If NSAIDs are the trigger, the plan usually involves stopping or changing those medications and using a proton-pump inhibitor (a strong acid blocker) to let the lining heal.
These approaches work. Widespread H. pylori eradication therapy and proton-pump inhibitor use have driven a sharp decline in ulcer cases, hospital admissions, and deaths over recent decades. The takeaway: an ulcer is a very fixable problem once a clinician identifies what's behind it. Avoid guessing at doses on your own, and let a professional tailor the plan to you.
