Incessant farting is not necessarily rectal cancer. The increase of farting is actually mainly due to two factors: firstly, the intestines produce more gas and cannot be expelled; secondly, the intestinal peristalsis is accelerated, pushing the gas to be continuously expelled downward. The symptoms of farting are more often seen in: first, poor digestive function and increased gas production; second, abnormal gastrointestinal tract dysfunction; third, eating foods that are prone to gas production, or caused by drugs. Some common conditions of the intestinal tract, including inflammation, polyps and even tumors, as well as changes in physical state, diet structure, and the emergence of intestinal dysfunction or irritable bowel syndrome, may lead to corresponding intestinal symptoms, such as constipation, abdominal pain, diarrhea, and increased farting. In modern society, people live and work under great pressure, and irregular life and diet can easily lead to intestinal dysfunction. Dietary habits, living habits, environmental factors, and mental state can all affect the intestinal peristalsis. If there are changes in bowel habits or even mucus, bloody stools or mucopurulent stools, you need to go to the hospital for examination as soon as possible and do rectal finger examination and colonoscopy to exclude rectal cancer.
