Fart stinks. Why?

Feces accumulate in the intestine for a long time and cannot be discharged in time. Excessive fermentation will lead to fart odor. Intestinal bacterial infections and intestinal tumors can also cause fart odor symptoms. Garlic, leek, onion and meat foods can also cause fart odor. If accompanied by abdominal pain, diarrhea and other symptoms, you should seek medical examination in time.
