Farting is not necessarily bowel cancer, you can’t diagnose bowel cancer solely on the basis of the symptom of farting, it may also be caused by normal physiological phenomenon or gastrointestinal dysfunction. 1. Pathological phenomenon: (1) Bowel cancer: when the patient suffers from bowel cancer, the tumor will press the intestinal tract and block the intestinal tract, and the intestinal contents will produce more gases under the action of intestinal fluids and bacteria, and thus “farting a lot” may appear. (2) Gastrointestinal dysfunction: When patients suffer from enteritis and other intestinal diseases, due to gastrointestinal dysfunction, the frequency of farting will usually increase, accompanied by indigestion. 2. Physiological phenomenon: If patients often eat potatoes, soybeans, fava beans, sweet potatoes and other foods that produce more gas in the intestines, they will also have farting symptoms, which will be alleviated when they reduce the consumption of these foods. It is recommended that when patients have farting symptoms, they can go to the hospital for consultation after eliminating physiological factors, so as to clarify the cause of the disease and carry out treatment under the guidance of the doctor.
