Reflux gastritis is also known as bile reflux gastritis and there is no substantial difference. Bile reflux gastritis is often referred to as reflux gastritis, also called alkaline reflux gastritis. It is an inflammation due to the dysfunction of the pyloric sphincter, or the flow of bile, pancreatic fluid and other duodenal contents into the stomach caused by gastric pylorus surgery, and damage to the gastric mucosa, resulting in inflammation. Patients will experience a more pronounced heartburn, bloating, vomiting, and in severe cases, bleeding. Diagnosis of this disease needs to go to the hospital gastroenterology department for gastroscopy, through gastroscopy to observe the degree of damage to the esophagogastric mucosa, to further understand the degree of reflux. It is recommended to go to the gastroenterology department of the hospital in time, complete the relevant examinations under the guidance of the doctor, standardize the treatment, and eat a light diet in daily life, do not eat greasy and stimulating food to avoid aggravation of the condition.
