The primary cause of Peptic Ulcer Disease in children is H. pylori infection. Helicobacter pylori is a type of bacteria that can infect the stomach lining and is known to contribute significantly to the development of peptic ulcers. Research indicates that these bacteria disrupt the protective mucous layer of the stomach, allowing gastric acid to damage the underlying tissue, which can lead to ulcer formation.

While stress, excessive consumption of spicy foods, and food allergies can influence gastrointestinal health and contribute to digestive discomfort, they are not the primary causes of peptic ulcers in the pediatric population. In fact, the role of stress in ulcer development is often overstated, and dietary factors alone, such as spicy foods, do not typically lead to the formation of ulcers unless an underlying condition, such as an H. pylori infection, is present. Understanding the correct primary cause is crucial for effective diagnosis and treatment, especially in school health settings, where early identification can lead to better health outcomes for children.
