11). Clinicаl: Gаstrоintestinаl bleeding during infancy and childhооd is a prevalent condition, accounting for 6–20% of the pediatric population in pediatric intensive care units. Upper gastrointestinal bleeding (UGIB) encompasses bleeding originating from the gastrointestinal tract proximal to the ligament of Treitz. It typically manifests as hematemesis (vomiting of blood), melena (black, tarry stools), or hematochezia (passage of fresh blood per rectum). UGIB in children presents unique diagnostic and therapeutic challenges, making it a focal point of pediatric gastroenterology. Among the numerous etiological factors, Helicobacter pylori (H. pylori) infection and non-steroidal anti-inflammatory drug (NSAID) usage are particularly notable. These factors are common in children and are well-established risk factors for gastrointestinal mucosal injuries. A very acidic diet does not directly cause H. pylori infection, but it can worsen the symptoms of an existing infection and increase the risk of ulcer development. Diets high in salt, processed foods, and very acidic items can create a more favorable environment for the bacteria and accelerate damage to the stomach membrane. To prevent worsening of symptoms, it is recommended to consume spicy foods, alcohol, coffee, acidic items and citrus fruits.
