Why does it always stink?

Farting odor may be related to daily diet. After ingesting a large amount of animal protein and fat, it will show this kind of farting odor after fermentation by human body. If constipation lasts for a long time, feces will accumulate in the intestinal tract for a long time, and the intestinal tract will nourish bacteria, showing that farting is more smelly. It is also likely caused by intestinal diseases, such as acute enteritis, chronic cholecystitis, chronic pancreatitis, etc.
