Stomach pain when hungry is not necessarily due to stomach cancer, but mostly due to chronic gastritis or peptic ulcers such as duodenal ulcers. In the case of chronic gastritis, there are usually symptoms such as upper abdominal fullness, acid reflux and heartburn; in the case of duodenal ulcer, there is usually a dull pain in the upper abdomen, and it usually occurs between meals, before meals and at night, with a certain periodicity. In the case of stomach cancer, it is more typical to have symptoms such as nausea and stomach pain more obvious after eating, loss of appetite, emaciation, nausea and vomiting, but since the early symptoms are not specific, they are not easily distinguished from diseases such as indigestion. If you have stomach pain when you are hungry, you can go to the gastroenterology department for gastroscopy to clarify the cause so as not to delay the disease. It is important to eat foods that are easy to digest in daily life instead of stimulating foods such as spicy, raw and cold, and too acidic.
