The reason for bloating after eating is usually due to swallowing too much air when eating, or eating cold, indigestible food that slows down intestinal peristalsis, thus causing abdominal distension. After a period of time, if there is still bloating, it is necessary to consider that it may be caused by disease factors, such as chronic gastric disease, intestinal obstruction, stomach tumors, irritable bowel syndrome, etc., can be clarified after the cause of symptomatic treatment: 1, chronic gastric disease: from the prolonged acute gastritis, excessive smoking and irregular diet, long-term use of drugs that damage the gastric mucosa, triggering the symptoms of chronic gastric disease, can be manifested as fasting epigastric fullness and discomfort; 2, intestinal obstruction: when intestinal obstruction occurs, it can lead to symptoms such as abdominal distension and abdominal pain when the patient has not eaten; 3, irritable bowel syndrome: patients with irritable bowel syndrome have visceral hypersensitivity, and the pain threshold for colorectal dilatation is significantly lower than normal, which is more likely to produce symptoms such as abdominal distension and abdominal pain; 4, stomach tumors: common ones are cysts, adenomas, smooth muscle tumors, malignant tumors including Stomach cancer and mesenchymal tumor, etc., can cause abdominal fullness and discomfort. In addition, gallstones, cholecystitis and other hepatobiliary diseases can also affect normal digestion due to spasm of the biliary sphincter, resulting in symptoms such as upper abdominal discomfort and inflation. Patients need to seek timely medical attention to improve the diagnosis after examination and then carry out symptomatic treatment.
