The feeling of blockage in the stomach after eating may be caused by functional dyspepsia, chronic gastritis, intestinal obstruction and other reasons. 1. Functional dyspepsia: Gastrointestinal dyskinesia, Helicobacter pylori infection, anxiety, depression and other causes can lead to functional dyspepsia, which is a group of clinical syndromes without organic diseases. The main symptoms are postprandial fullness, early satiety, middle and upper abdominal pain. 2. Chronic gastritis: Helicobacter pylori infection, autoimmunity, alcohol, NSAIDs and other factors can cause chronic inflammatory lesions of the gastric mucosa. Symptoms such as discomfort, fullness, dull pain in the upper and middle abdomen, lack of appetite, nausea, acidity and other dyspepsia may occur. 3. Intestinal obstruction: fecal mass, tumor, inflammatory stenosis, congenital malformation and other factors can cause obstacles to the passage of intestinal contents. There may be abdominal pain, abdominal distension, vomiting, stopping of defecation and other manifestations. These symptoms may be aggravated by the increase in intestinal contents after eating. If you have the above symptoms, you need to go to the hospital as soon as possible to clarify the cause, and the doctor will formulate an individualized diagnosis and treatment plan according to the specific condition, so as to avoid delaying the condition.
