Our body is rich in colors and shades, both inside and outside. These colors act as health indicators that allow physicians to detect any health problems. Stool color, for example, is one of the most revealing aspects of what is happening inside our body.
How is stool created?
By eating foods we bring to our body a significant amount of nutrients needed for proper operation, water, and other substances found in food products such as additives and dyes. In making their journey through the digestive system, these foods are broken down and digested to extract the contents our body needs, and the rest is directed to the intestines and into the rectum to be expelled out of the body: that is a stool.
Composition of stools
When they are normal, stools are composed of 75% water and 25% solids. These are divided into three equal parts: bacteria, non-digestible fiber and other waste that the body eliminates.
In case of diarrhea or constipation, stool composition and consistency change, with higher water content for the first case (loose stools), and a harder consistency with difficulty of evacuation for the second.
The color of the stool
Stool color is one of the most important indicators of the health of our digestive system and our body.
The brown color of a stool is the most natural. It is caused by bile. This green liquor is produced by the liver and stored in the gallbladder, before being released in the small intestine where it contributes to the absorption of fats and vitamins, as well as softens the stool to facilitate their evacuation. Circulating in the intestines, bile color changes due to the action of bacteria of the intestinal flora, from green, to yellow and finally brown and gives the color of the stool.
