Peptic ulcers are open sores that develop on the inner lining of the digestive tract, specifically in the stomach or the upper part of the small intestine. While they share a similar biological cause, they are named based on their specific anatomical location. A sore located in the stomach is referred to as a gastric ulcer, whereas one located in the first section of the small intestine is known as a duodenal ulcer. Both conditions are heavily influenced by the presence of stomach acid and the breakdown of the protective mucosal barrier. Understanding these distinctions is vital for clinical management in the United Kingdom, as the timing of symptoms and the approach to diagnosis can vary slightly depending on where the ulcer is situated.

Stomach ulcers and intestinal ulcers are both types of peptic ulcers but occur in different parts of the digestive system
While the term peptic ulcer covers both conditions, a stomach ulcer occurs on the stomach lining, and an intestinal ulcer occurs in the duodenum. Stomach ulcers are open sores that develop on the lining of the stomach or the part of the small intestine just beyond it. These sores form when the protective mucus layer that prevents acid damage becomes compromised, allowing gastric juices to erode the underlying tissue. Although the biological mechanism of injury is nearly identical, the specific location of the sore can influence how a patient experiences pain and how a healthcare professional prioritises investigative tests.
Key differences in symptoms and timing of pain
One of the most significant ways to distinguish between these two types of ulcers is by observing when the pain occurs in relation to eating. Gastric ulcers often cause pain shortly after eating, as the stomach produces more acid to digest the food, which then irritates the open sore. In contrast, duodenal ulcers frequently cause pain several hours after a meal or during the night when the stomach is empty. The most common symptom of a stomach ulcer is a burning or gnawing pain in the centre of the tummy, which may feel different depending on whether the sore is in the stomach or the intestine. Some individuals with duodenal ulcers find that eating actually temporarily relieves their discomfort, whereas those with gastric ulcers may find eating makes it worse.
Shared causes: H. pylori and NSAID use
Despite their different locations, both types of ulcers are primarily caused by the same two triggers: an infection with Helicobacter pylori (H. pylori) bacteria or the use of specific anti-inflammatory drugs. H. pylori bacteria weaken the protective coating of the stomach and duodenum, making them vulnerable to acid. According to the National Institute for Health and Care Excellence, H. pylori infection and the use of NSAIDs are the two main causes of peptic ulcers. Medications like ibuprofen and aspirin can inhibit the chemicals that maintain the mucosal barrier. In the UK, identifying these triggers through breath, stool, or blood tests is a standard part of the clinical pathway for any suspected peptic ulcer.
Comparison of Peptic Ulcer Types
| Feature | Gastric (Stomach) Ulcer | Duodenal (Intestinal) Ulcer |
| Location | Stomach lining | First part of small intestine |
| Pain Timing | Often occurs soon after eating | Often occurs hours after eating or when empty |
| Effect of Food | May worsen the pain | May temporarily relieve the pain |
| Common Cause | H. pylori or NSAID use | H. pylori or NSAID use |
Diagnostic and treatment pathways in the UK
The medical approach to treating both gastric and duodenal ulcers is largely the same, focusing on reducing stomach acid and eliminating any underlying infection. Treatment for stomach ulcers involves taking medicines to reduce the amount of acid the stomach produces such as proton pump inhibitors (PPIs). If an H. pylori infection is confirmed, a combination of antibiotics is prescribed to clear the bacteria. A gastroscopy, where a camera is used to view the lining of the digestive tract, is the most definitive way to determine the exact location and severity of the ulcer. Following the full course of prescribed medication is essential to ensure the tissue heals completely and to prevent the sore from returning.
Conclusion
A stomach ulcer and an intestinal ulcer are both peptic ulcers, but they are distinguished by their specific location within the digestive tract. While they share common causes like H. pylori and NSAID use, they may present with different patterns of abdominal pain. Accurate diagnosis through clinical testing is necessary to provide the correct treatment and support full healing of the digestive lining. If you experience severe, sudden, or worsening symptoms, call 999 immediately.
Can I have both types of ulcers at the same time?
Yes, it is possible for some individuals to develop sores in both the stomach and the duodenum simultaneously.
Which type of ulcer is more common in the UK?
Duodenal ulcers are generally considered more common than gastric ulcers, though both are frequently diagnosed in primary care.
Is the treatment different for an intestinal ulcer?
The core treatment remains the same for both, involving acid suppressants and antibiotics if a bacterial infection is present.
Does smoking affect both types of ulcers?
Yes, smoking increases the risk for both gastric and duodenal ulcers and can significantly slow down the healing process.
Can an intestinal ulcer cause back pain?
In some cases, the pain from a duodenal ulcer can radiate toward the back, though this requires medical investigation to rule out other issues.
Are these ulcers caused by spicy food?
Spicy food does not cause ulcers in either location, but it can irritate an existing sore and make symptoms more noticeable.
How do I know if my ulcer is bleeding?
Signs of a bleeding ulcer include dark, tarry stools or vomit that looks like coffee grounds, both of which require urgent medical care.
