Fart odor is not necessarily a clinical manifestation caused by taking probiotics, and it is likely to have a lot to do with itself. Fart stinks because food stays in the intestine for a long time, and food is a clinical symptom caused by incomplete fermentation. Probiotics can promote the digestion and absorption of food, so it is recommended to continue to use them, and at the same time, they can be treated with some digestive drugs.
