If my stomach hurts when I stand but not when I lie down, could it be stomach cancer?

If your stomach hurts when you stand but not when you lie down, it may be due to non-disease factors such as improper diet and chronic superficial gastritis. However, it does not rule out Helicobacter pylori infection, gastric ulcer or gastroesophageal reflux disease.

1. Non-disease factors:

1. Improper diet: Eating too much spicy food may damage the gastrointestinal mucosa and cause pain and discomfort. When standing, the abdominal pressure increases, which may aggravate the phenomenon.

2. Other situations: The above symptoms may also occur after the abdomen is exposed to cold, accompanied by diarrhea and other symptoms. It may also be related to factors such as mental stress. It is recommended that patients go to the hospital in time for treatment and complete examinations to confirm the diagnosis.

1. Helicobacter pylori infection: It is often caused by long-term neglect of personal hygiene and cleanliness, and is often manifested by upper abdominal pain, fullness before meals, and belching. During X-ray barium contrast examination, niche-like filling defects can be seen. At this time, you need to take omeprazole enteric-coated capsules, amoxicillin clavulanate potassium tablets and other drugs as prescribed by the doctor;

2. Gastric ulcer: usually refers to a digestive ulcer disease that occurs in the gastric angle, gastric antrum and cardia, which is mainly considered to be related to Helicobacter pylori infection and autoimmune abnormalities. The typical clinical feature is periodic rhythmic upper abdominal pain, and most of them will occur about half an hour after a meal, so the above situation will occur. Generally, it can be relieved under the guidance of a doctor with drugs such as rabeprazole sodium enteric-coated tablets and bismuth potassium citrate granules;

3. Gastroesophageal reflux disease: usually due to decreased anti-reflux function or decreased esophageal clearance, which causes food to enter the throat through the lower end of the esophagus, causing heartburn and dysphagia. If the condition is more serious, it will also be accompanied by nausea and vomiting, and may even cause a burning or tingling sensation behind the sternum. It is necessary to cooperate with the doctor to take oral drugs that inhibit gastric acid secretion to improve, such as famotidine dispersible tablets, ranitidine hydrochloride capsules, etc.

In addition to the above common causes, it may also be caused by a variety of diseases such as duodenal gastric ulcers, pancreatic tumors, etc. It is recommended to develop good living habits in daily life, avoid overeating, and exercise appropriately to enhance physical fitness.
