Which of the following factors is linked to the development of peptic ulcers?

The development of peptic ulcers is closely associated with an infection by Helicobacter pylori (H. pylori). This bacteria is known to colonize the stomach lining, leading to inflammation and damage to the protective mucosal barrier. When this barrier is compromised, gastric acid can erode the tissue more easily, resulting in the formation of ulcers.

Studies have shown that H. pylori infection is a primary causal factor in both gastric and duodenal ulcers. Treatment typically involves a combination of antibiotics and acid-reducing medications to eliminate the bacteria and allow for healing of the ulcerated area.

Other factors like lack of hydration, a high fiber diet, and frequent exercise do not have a direct role in ulcer formation. While these factors can influence overall gut health and digestion, they are not linked in the same way as H. pylori to the specific pathological process that leads to peptic ulcers.
