Feeling something blocked in the stomach all the time may not necessarily be stomach cancer, but may also be caused by other digestive system diseases, which should be analyzed on a case-by-case basis. Stomach feeling blocked by something may be a manifestation of gastric distension, which is mostly caused by irregular diet, not stomach cancer. If stomach distension is only occasional, it can be regulated by paying attention to diet, such as 7-8 minutes full, less spicy and fried food, and taking oral Chinese medicine. If the stomach is bloated repeatedly or for a long time, accompanied by nausea and vomiting, chronic gastritis, gastric ulcer, gastric cancer and other related diseases should be considered, and gastroscopy is recommended in the gastroenterology department of the hospital. Stomach cancer can also cause the feeling of something blocking the stomach. Patients are usually advised to develop good eating habits, not to lie down immediately after meals, to help gastrointestinal digestion by taking a walk and to maintain a relaxed mood.
