The liver produces bile juice that is bright green in color. It is stored in the gallbladder from where it passes down to the intestinal tract. When it travels down the intestine, the color changes from bright green to brown. During normal digestion, the process takes enough time for the bile to change color. However, when bile reaches the intestine faster than normal time, it gets mixed up with the stools without change in color. This is called 'rapid transit' or 'decrease colonic time'.
For stool to pass properly through the bowels, fiber is needed. Fiber gives the stool its bulk and helps its movement through the intestines. When the fiber content is less, the stool has less bulk and becomes hard, dry and is more difficult to pass out. This leads to constipation, bloating and even rectal bleeding at times. Thus, it is important to consume high-fiber foods like fruits and vegetables. Including whole grains to the diet is also helpful. People with mild constipation problems can obtain relief just by consuming a high-fiber diet. Moreover, this a good stool softener for children.
As far as normal bowel movement is concerned, there is no specific definition as it depends on several criteria. However, according to the health experts, a medial brown colored stool (or any shade of brown) is considered normal. Occasional yellow stool also signifies normal bowel movement. Other factors that signify healthy digestive system are toothpaste like consistency, sinking in water, presence of little gas, and smooth passing of stool without straining.
In order to comprehend why the stool color in adults, sometimes changes to green, one needs to focus on how the digestive system functions. The liver is responsible for producing bile. Bile is a fluid that aids in fat absorption and fat-soluble vitamins. The bile once secreted, divulges into the small intestine or in the bladder. Bile plays a major role in deciding the color of the stool and the consistency as well. The stool being thick, slim or watery, and the color being white, brown or green, depends upon the way the bile fluid functions and gets secreted. In a normal healthy stool, the bile color changes from green, progressing to yellow and finally brown. Thus, it could be concluded that the cause of green poop in adults may be due to the fact that the feces has not passed through the intestine at a normal pace, hence leaving the color unchanged. This is a malfunction of the bowel movement and is termed decreased bowel transit. Another factor contributing to the causes of green stool is the presence of mucus in the intestine. This may cause its color and the consistency to change.
