Stomach gurgling is not necessarily an early reaction to cancer; in most cases, it is caused by other diseases. In most cases, stomach gurgling is caused by other diseases, such as excessive acidic food, indigestion, gastritis and enteritis. Patients with indigestion produce more gas in the gastrointestinal tract, and the symptoms of stomach gurgling are more pronounced after meals, and the bowel sounds are more than 5 times per minute. Stomach gurgling caused by acute gastroenteritis may be accompanied by severe diarrhea, abdominal pain and other symptoms. And in patients with gastrointestinal hemorrhage, the number of bowel sounds is about 10 times per minute and the loudness will become louder and louder. Usually patients with stomach cancer have no obvious symptoms in early stage, but some of them can also have indigestion symptoms, which may manifest as stomach rumbling. If patients are too worried and suspect that they have stomach cancer, they can go to the hospital to have a gastroscopy and have a blood test. If it is a case of indigestion or intestinal inflammation, you can follow medical advice to improve your lifestyle and take appropriate medication, so that even in case it is a case of cancer, it can be detected early and treated early.
