What Are Stomach Ulcers?

Stomach ulcers, also called peptic ulcers, are open sores that form on the inner lining of your stomach or the upper part of your small intestine. They develop when stomach acid damages this protective lining.

Here’s a quick breakdown of the types of ulcers:

      • Gastric Ulcers – These occur in the stomach lining.
      • Duodenal Ulcers – These form in the lining of the upper part of the small intestine (duodenum).

→ Common Causes of Stomach Ulcers

      • H. Pylori Bacteria – A common bacterial infection that inflames and weakens the stomach lining.
      • NSAID Overuse – Regular use of nonsteroidal anti-inflammatory drugs like ibuprofen or aspirin can erode the stomach lining.
      • Excess Acid Production – Conditions like Zollinger-Ellison syndrome increase stomach acid, making ulcers more likely.
      • Lifestyle Factors – Smoking, high alcohol intake, and stress may aggravate symptoms or delay healing but are not direct causes.

Can Stomach Ulcers Lead to Cancer?

Here’s the important part—stomach ulcers themselves don’t turn into cancer. However, the underlying issues that cause ulcers can raise your stomach cancer risk.

→ Key Risk Factors

    • H. Pylori Infection
      Often linked to peptic ulcers, this bacterium causes chronic inflammation, which can damage cells and eventually lead to stomach cancer.
    • Chronic Untreated Ulcers
      Long-lasting damage increases the chances of precancerous changes, such as intestinal metaplasia or dysplasia.
    • Long-Term NSAID Use
      Prolonged use of these drugs weakens the stomach lining, increasing ulcer recurrence and the risk of complications.
    • Smoking and Alcohol
      Both irritate the stomach lining and worsen inflammation.

H. Pylori – The Link Between Stomach Ulcers & Cancer

Helicobacter pylori, or H. pylori, is one of the most significant factors connecting stomach ulcers to cancer. This bacteria infects the stomach lining, leading to inflammation (gastritis) that can last for years if untreated.

    • Chronic inflammation caused by H. pylori can cause DNA damage, increasing your risk of gastric cancer over time.
    • Studies show that eliminating H. pylori reduces the risk of stomach cancer, even in people with precancerous changes.

Should You Get Tested for H. Pylori?

Yes, especially if you have symptoms like persistent pain, bloating, or a history of ulcers. Tests include a breath test, stool test, or endoscopic biopsy.

Not always, but long-term infection increases the likelihood, especially if untreated.

4️⃣ What foods should I avoid with ulcers?

Spicy foods, acidic beverages, alcohol, and processed meats can irritate the stomach lining.
