There are many reasons for farting, as follows: first of all, it is likely that due to their poor diet, eat more indigestible food. This makes too much gas inside the intestines and stomach, and the bacteria inside the intestines will produce smelly gas after decomposing the food, thus causing the phenomenon of farting. Secondly, it is likely that you have eaten high-protein foods, such as eggs. High-protein foods produce smelly gas after digestion and absorption in the intestines. Once again, it is likely that the patient’s intestines have caught a chill, which has slowed down the peristalsis of the intestines and caused the food to remain in the body for a longer period of time, thus producing smelly farts. If there is a fart situation, it is recommended that patients should pay more attention to their dietary habits, eat more fruits and vegetables, avoid eating spicy, stimulating and cold foods, and eat a light diet.
