Farting during exercise is not the breakdown of fat, it is caused by a problem with gastrointestinal peristalsis. Gas is retained in the body, and when the abdominal pressure rises during exercise, gastrointestinal peristalsis is accelerated, so the gas in the intestinal canal is discharged from the body, and the farting occurs. This phenomenon mostly indicates that patients usually have little exercise and weak body, especially poor gastrointestinal function, so they should try to do more exercise, which can improve the peristalsis of the stomach and intestines and reduce the accumulation of gas in the body. Ventilation itself is good for the body, so try not to hold it in. At the same time, we should also pay attention to the diet, and properly reduce the food that can easily cause bloating, such as groundnuts, carbonated drinks and soy products, etc., because these foods can easily cause exhaustion, especially when it comes to exercise.
