Patients with upper gastrointestinal bleeding are advised not to drink milk. Although milk can dilute gastric acid, it can stimulate the secretion of gastric acid, exacerbating symptoms of upper gastrointestinal bleeding. In severe cases, it can lead to a recurrence of upper gastrointestinal bleeding. Therefore, patients with upper gastrointestinal bleeding should avoid drinking milk during the acute phase. After the onset of upper gastrointestinal bleeding, it is recommended to visit the gastroenterology department of a formal hospital as soon as possible, and complete auxiliary examinations such as an electronic gastroscopy to clarify the diagnosis. Additionally, treatment for upper gastrointestinal bleeding can be carried out through relevant endoscopic therapies. Patients with upper gastrointestinal bleeding should consume easily digestible foods in their diet.
