Nausea and vomiting after eating may be caused by mental anxiety, gastritis, pyloric obstruction, etc., and need to be treated with drugs such as omeprazole, domperidone, etc. or surgery according to the specific disease.
1. Mental anxiety may increase the excitability of the parasympathetic nerves, causing gastrointestinal dysfunction, which in turn causes nausea and vomiting after eating. It is recommended to improve the mental state by listening to music and doing exercise, and if necessary, psychological counseling is needed.
2. Gastritis may lead to congestion and swelling of the gastric mucosa, causing nausea, vomiting, belching and other symptoms. It is recommended to take medicines to inhibit gastric acid (e.g., omeprazole, etc.) and to promote gastric motility (e.g., domperidone, etc.) under the guidance of the doctor for treatment.
3. Pyloric ulcer will cause edema and spasm of the pylorus, which will prolong the retention time of gastric contents in the stomach and lead to abdominal distension, nausea, vomiting, etc. If it is caused by ulcers, acid-suppressing medicines (e.g., omeprazole, etc.) need to be taken, and in severe cases, surgery is needed.
It is recommended to use medication under the guidance of a doctor and to follow the doctor’s instructions.
