Causes of stomach pain and vomiting include gastritis, gastric perforation and stomach cancer. The causes of the disease are different, and the treatment methods are also different. Commonly used treatments include medication, surgery, radiotherapy and so on. 1. Gastritis: Due to inflammation and infection in the stomach, inflammatory factors stimulate the gastric mucosa and trigger stomach spasm, thus causing patients to suffer from stomach pain, vomiting and other symptoms. You can choose medication, such as omeprazole, mosapride, penicillin, etc., to protect the gastric mucosa, stimulate gastrointestinal dynamics, control inflammation and infection, so as to improve the patient’s discomfort symptoms. 2. Gastric perforation: due to gastric ulcers, trauma and other factors, causing damage to the stomach wall, penetrating the abdominal cavity, resulting in the flow of gastric contents into the abdominal cavity, triggering the patient to experience stomach pain, vomiting symptoms. You can choose medication, such as omeprazole, aluminum magnesium carbonate chewable tablets, cefuroxime sodium, etc., to inhibit the secretion of gastric acid, protect the gastric mucosa, control the infection and improve the patient’s discomfort. If the degree of perforation is more serious, surgical treatment can also be chosen, such as major gastrectomy, perforation suture surgery and partial gastrectomy. 3. Gastric cancer: due to the cancerous transformation of cells in the stomach tissues. Clinically, according to the stage of gastric cancer, surgical treatment, such as partial gastrectomy and total gastrectomy, is the main treatment. It can also be combined with radiotherapy, chemotherapy, targeted therapy and other methods for comprehensive treatment to improve patients’ discomfort symptoms. If the patient has frequent stomach pain, vomiting and other symptoms, it is recommended that the patient go to the hospital in time. Improve the gastroscopy, CT and other tests to clarify the cause of the disease, and follow the doctor’s instructions for treatment, so as not to delay the condition. Drugs need to be used under the guidance of a professional physician, do not self-medicate.
