The desire for nausea and vomiting after eating may be related to psychosomatic factors, poor dietary habits, pregnancy or gastritis, gastric ulcer and other factors, which can be dealt with according to different triggers. I. Non-organic lesions 1. Psychosomatic factors: If you are in a long-term anxiety, tension, worry, mental stress, so that the excitability of the parasympathetic nerve increases, resulting in gastrointestinal tract dysfunction, easily triggering nausea and vomiting after eating. You can divert your attention and relax your mind by listening to music, chatting and walking, which can gradually relieve the symptoms; 2. Bad dietary habits: Patients eating unclean food or unreasonable dietary structure may cause inflammation of the gastrointestinal tract, so that the peristaltic capacity of the gastrointestinal tract decreases and the lack of gastric power leads to the accumulation of food, which may cause nausea and vomiting after eating. Therefore, pay attention to dietary hygiene, do not eat spoiled and contaminated food, avoid excessive intake of greasy, cold, spicy and stimulating food, can eat light, easy to digest food, do not overeat, while reducing the intake of coffee, strong tea and other stimulating drinks; 3, pregnancy: women of childbearing age after sex if nausea, vomiting and other performance, may be due to changes in hormone levels in the body after pregnancy caused by the gastrointestinal reaction, i.e. early pregnancy reaction. It can be clarified by ultrasound examination or blood test for HCG, adjusting the diet and lifestyle, eating more fresh fruits and vegetables, eating less and more meals, and the symptoms can be gradually relieved after 12 weeks of pregnancy. Second, organic diseases 1, gastritis: inflammation leads to gastric mucosa congestion, edema, injury, promote gastric acid secretion after eating, gastric acid stimulation of gastric mucosa can cause epigastric discomfort, belching, nausea, acid reflux, vomiting performance. It is usually necessary to apply omeprazole and ranitidine to inhibit gastric acid secretion, domperidone and mosapride to promote gastric motility, digestive enzymes to improve gastrointestinal digestive function, and quadruple therapy to eradicate H. pylori if necessary. 2. Gastric ulcer: ulcer surface appears in the broken mucosa of the stomach lining, and food stimulation after eating can easily cause stomach discomfort, accompanied by abdominal distension, belching, nausea, and vomiting. Under the guidance of the doctor, the application of rabeprazole, pantoprazole to inhibit gastric acid secretion, bismuth potassium citrate, aluminum thioglycollate and other drugs to protect the gastric mucosa, thereby reducing discomfort; 3, pyloric obstruction: pyloric ulcer in the anterior pyloric region leads to pyloric edema, spasm, stenosis, the inability to pass the stomach contents after eating, delayed gastric emptying triggers epigastric distension, while nausea, vomiting symptoms can occur. Patients with obstruction need to fast from food and water, continuous gastrointestinal decompression, and rehydration to correct water-electrolyte disturbance. If the symptoms are more serious, gastrojejunostomy and gastrectomy are needed to relieve the obstruction and relieve the symptoms. 4. Gastric cancer: Cancer cells invade the blood vessels and tissues of the stomach, resulting in abnormal digestive system. Usually, radical surgery should be applied to remove the lesion and nearby lymph nodes, and adjuvant chemotherapy should be applied to alleviate the digestive tract symptoms.
