The causes of gastrointestinal bleeding vary by age. Objectives: To describe the clinical, subclinical and common causes of non-infectious gastrointestinal bleeding in children. Subjects and methods: Patients from 2 months to 15 years old admitted to Pediatrics Department I, Pediatric Center, Hue Central Hospital from February 2020 to February 2021 with a diagnosis of gastrointestinal bleeding.

The mean age was 7.6 ± 4.6. Peptic ulcer disease is the most common cause of GI bleeding, accounting for 37%; 12.9% cases unknown cause. Most of the patients had mild and moderate GI bleeding, about 60.3% and 23.3%; severe bleeding 8.6% and very severe 7.8%.
