Peptic Ulcers: Symptoms, Irritation Triggers, and Awareness

A peptic ulcer is an open sore that forms in the lining of the stomach or the upper portion of the small intestine. Ulcers may be referred to as gastric or duodenal ulcers depending on their location. One known contributor to ulcer development is the bacterium Helicobacter pylori (H. pylori), though other factors may also play a role.

First Aid & Workplace Relevance (Canada)

Digestive discomfort can affect hydration, concentration, and mealtime routines—important considerations in workplaces with shift work, food service, or high stress. Awareness helps individuals recognize when persistent symptoms may require assessment from a healthcare professional.

Scenario (Mild & Realistic)

A retail worker noticed a burning stomach discomfort that came and went over several weeks, especially between meals. They started logging symptoms and shared their notes during a routine check-up.


Common Symptoms

Understanding peptic ulcers and their causesPeptic ulcers often cause a burning or gnawing sensation in the upper abdomen. Symptoms may:

  • Fluctuate across days or weeks

  • Appear between meals or at night

  • Temporarily improve after eating in some cases

Other digestive symptoms—such as bloating, burping, or early fullness—may also occur.


Potential Contributors

Several factors may contribute to ulcer formation or irritation, including:

  • H. pylori infection

  • Medications that affect the stomach lining

  • Smoking

  • Stress

  • Dietary patterns

  • Individual sensitivity to certain foods and drinks


Food and Irritation

Some people notice that certain foods feel more irritating during an ulcer flare-up, while others feel soothing. Irritation can vary widely between individuals, but commonly reported triggers include:

  • Highly acidic foods

  • Spicy dishes

  • Very fatty or fried items

  • Caffeine or alcohol

Others find that milder foods (such as bananas, oatmeal, or soft fruits) feel easier to tolerate. These observations are based on individual comfort rather than treatment.


Bacteria and the Digestive System

Interest in the role of bacteria—both harmful and beneficial—continues to grow in digestive research. Foods like yogurt and fermented products contain live cultures that contribute to discussions about the microbiome, though their role in ulcer management varies and remains individualized.


Hydration & Mealtimes

Drinking fluids and eating smaller, more frequent meals can help some individuals manage discomfort. Reactions to dairy, fruit, grains, or herbal products vary between people, and healthcare guidance is commonly used to avoid interactions with medications.
