Intestinal tinnitus and farting is usually not a manifestation of intestinal cancer, but mostly due to other factors. It is mainly related to the rapid peristaltic movement of gastrointestinal tract or the recent consumption of too much food with high protein, such as eggs, refined meat and seafood, etc. The gas produced by the decomposition of such food is more, and the increased gas production can stimulate intestinal peristaltic movement, thus increasing the intestinal tones and exhaust. Secondly, dysbiosis of gastrointestinal flora may also lead to increased exhaust and foul smell. The most common symptom of bowel cancer is blood in the stool, which is darker and darker red in color. In addition, the change of stool habit, mainly the increase of stool frequency, and some patients may also have alternating constipation and diarrhea. Therefore, in daily life, one should develop good living habits, avoid staying up late, keep a happy mood, reduce the intake of spicy stimulating and greasy food, and appropriately supplement probiotics to regulate the intestinal flora environment.
