Gastritis can cause symptoms of nausea and vomiting, or the appearance of nausea and desire to vomit but not vomiting, commonly in patients with acute gastritis, chronic gastritis, peptic ulcer, and also gastroesophageal reflux disease, and also in patients with gastric cancer. When patients experience nausea and desire to vomit, if it is clear that it is due to gastritis, such as acute or chronic gastritis, they can be treated with self-administered acid suppressants, and can take proton pump inhibitors such as oral omeprazole or lansoprazole. If the patient is not completely clear that the vomiting is caused by diseases of the stomach, you need to go to the hospital and cooperate with the doctor to improve the relevant tests, such as checking the abdominal ultrasound, electronic gastroscopy, etc., and give specific medication after the clear examination. It should be reminded that women of childbearing age must pay attention to the exclusion of early pregnancy reaction, because the symptoms of nausea and vomiting can also occur during early pregnancy reaction.
