Bile reflux is not normal in young people. Bile reflux is the retrograde movement of bile into the stomach, or the lower part of the esophagus. Patients should visit a hospital to avoid delaying treatment and worsening the condition. Normal peristalsis of the digestive tract, including the secretion and outflow of bile, is carried in the inherent direction, under the control of the smooth muscle and sphincter of the digestive tract, with the gastrointestinal tract to the distal end. Bile reflux indicates that the function of the pylorus and cardia of the stomach has decreased to a certain extent and cannot control bile reflux. In this case, the patient needs to follow the doctor’s prescription for treatment, and if necessary, to cooperate with the doctor to apply medication, such as aluminum thioglycollate, misoprostol and other gastric mucosal protective agents to protect the gastric mucosa from damage. Gastric motility drugs such as domperidone and etopride can also be applied as prescribed by the doctor to make the digestive juices run distally. If patients have stronger discomfort such as acid reflux, nausea and vomiting, they can also apply drugs that inhibit gastric acid such as omeprazole and rabeprazole to improve the discomfort under the guidance of doctors. In case of repeated bile reflux, it will cause irritation to gastric mucosa and esophageal mucosa, which may cause gastritis, esophageal stricture and other lesions, and patients should pay attention to it. Patients with bile reflux should pay attention to a balanced diet, and can eat more fresh vegetables and fruits appropriately, and avoid spicy and stimulating foods to facilitate the recovery of the disease.
