Regurgitation and vomiting can be caused in two ways: 1. The condition of gastrointestinal dysfunction and digestive malfunction itself. This is common in cases of chronic gastritis, gastroesophageal reflux disease, gastric ulcer, etc. It is mostly related to inflammatory infections or irregular diet. In this case, it is necessary to give acid-suppressing drugs and symptomatic treatment with drugs that improve gastrointestinal dynamics. For example, omeprazole capsule, 2 capsules once, once a day; Mosapride citrate capsule, 2 capsules once, 3 times a day; Metoclopramide hydrochloride injection, 10mg once, 1-2 times a day. If oral medication is not relieved, intravenous fluid rehydration needs to be given to prevent electrolyte disorders. 2. Another aspect is recurrent nausea and vomiting, which cannot be completely ruled out for female patients with early pregnancy reactions. In this case, it is necessary to improve the HCG test of urine and blood to further exclude the diagnosis. Finally, symptoms of the digestive tract can be triggered by other aspects of the disease, such as intracranial hypertension, hypertensive disease, cerebral infarction, cervical spondylosis and other conditions, which can also present symptoms of nausea and vomiting, and need to be examined for correlation on a case-by-case basis and treated with symptomatic support after exclusion.
