It is recommended to check the stomach disease in the morning, not in the afternoon. Because a lot of tests for gastric disease need patients to fasting, such as doing Helicobacter pylori, for gastroscopy, gastrointestinal imaging and the corresponding CT of the stomach need patients to fasting to the hospital for further diagnosis and treatment. If you come in the afternoon, such as Helicobacter pylori is generally not tested, gastroscopy can be examined under special circumstances, the corresponding abdominal CT is also recommended to come in the morning. On the one hand, in the afternoon, the patient is hungry for a longer time, and may have an adverse reaction such as hypoglycemia due to hunger. On the other hand, many gastric examinations are not performed in the afternoon, so it is recommended that patients come to the hospital in the morning on an empty stomach to communicate with the gastroenterologist and have the appropriate diagnosis and treatment of gastric diseases.
