Farting and gurgling all day long may not necessarily be bowel cancer, but may also be caused by irritable bowel syndrome, gastrointestinal bleeding and catching cold. Early stage of bowel cancer usually has no obvious symptoms, only manifested as abdominal discomfort, indigestion, occult blood in stool, etc., which may be accompanied by anal discharge, and in the later stage, there will be abdominal pain, abdominal mass, blood in stool, and increase in the number of stools. Irritable bowel syndrome, i.e., functional disorders of the intestines, usually accompanied by abdominal pain, abdominal distension, gas, change of stool shape and other symptoms; gastrointestinal bleeding, intestinal sounds are particularly active, and then gastroenterologists usually determine whether the bleeding stops based on whether the intestinal sounds are active or not. In addition, when the abdomen is cold, it can also cause intestinal hyperfunction, which will result in stomach growling and increased exhaust, therefore, farting and stomach growling all day long may not necessarily be bowel cancer. Generally, increased exhaust and stomach grumbling can be recovered by themselves. If the symptoms are not relieved for a long time, patients should go to gastroenterology and other related departments in time to clarify the cause of the disease and get symptomatic treatment.
