It is mostly caused by weak intestinal peristalsis and indigestion.

Bad odor in stool indicates deterioration of the intestinal environment. The odor in stool comes from indole and skatole, which are substances formed by protein decomposition by intestinal bacteria.

People with European and American eating habits who consume a large amount of high-protein and high-fat foods every day will have foul-smelling stools.

On the contrary, people who eat more fiber have better stool smell.

The bad smell of stool is evidence of the deterioration of the intestinal environment, indicating that the number of putrefactive bacteria in the intestines has increased. The aging and deterioration of the intestinal environment will promote aging and disease in the human body.

For symptoms of indigestion, be careful not to eat too much at each meal, especially dinner. Just take some medicine to help digestion, such as Baohe Pills, Muxiang Shunqi Pills, Hawthorn Pills, etc. The composition of feces: food residues in the large intestine

In the intestine, part of the water and electrolytes are absorbed by the mucosa of the large intestine, and after bacterial fermentation and putrefaction, they become feces and are excreted.

Feces contains undigested cellulose from food, shed epithelial cells from the digestive tract, mucosal fragments and a large number of bacteria, as well as unabsorbed digestive tract secretions such as mucus, bile pigments, mucin and digestive juices.
