Pathological factors: if the patient suffers from gastroenteritis, dyspepsia, intestinal flora imbalance and other gastrointestinal diseases, it will lead to an increase in the decomposition of food in the gastrointestinal gas (especially sulfur-containing or nitrogen-containing gases), and the gastrointestinal peristalsis speeds up after the exercise so as to discharged the gas, resulting in more farting and stinking after the exercise.
