What is one potential consequence of H. pylori overgrowth?

H. pylori overgrowth has been closely linked to several gastrointestinal conditions, particularly the development of ulcers and associated stomach pain. This bacterium resides in the stomach lining and can erode the protective mucus barrier, leading to inflammation and the formation of ulcers. These ulcers can manifest as abdominal pain, discomfort, and sometimes more severe complications. The relationship between H. pylori and these conditions is well documented, making ulcers or stomach pain a recognized consequence of its overgrowth.

In the context of the other choices, the increase in digestive enzyme production is not a direct effect of H. pylori, and while some digestive enzymes may be produced, the overall effect of the bacteria is detrimental. Improved gut flora balance is unlikely, as H. pylori contributes to dysbiosis rather than a healthy balance of gut microbiota. Lastly, enhanced absorption of vitamins is also not associated with H. pylori, since the inflammation and damage caused by its presence often lead to gastrointestinal issues that can impair nutrient absorption.
