Bowel movement is the term used for discharge of feces from the large intestine. The act of expelling the waste particles through the rectum is known as bowel movement or defecation. Under normal conditions the color of the bowel would be in varying levels of brown.
Why The Feces Are Brown?
Our feces are brown in color due to the presence of leftover red blood cells and plenty of bacteria in it. Formation of bilirubin pigment in the liver and further breaking down process of this pigment where bacteria feed on them gives brown color to the fecal particles. Bile is normally yellow or yellowish green in color but bacteria works on it to convert it into brown. Feces would be dark brown if you are taking iron supplement or folic acid daily.
Green Bowel :
Any change in the normal bowel color is not a matter of concern all the time. Most of the time, it is your diet that changes the bowel color. If you have taken plenty of greens, leafy vegetables and flavored drink or ice pops then you may get green bowel movement for sure. Sometimes there may not be enough time given for the intestine for absorption of nutrients fully in the large intestine. Here bile secreted from the liver may not have sufficient time to completely break-down food particles causing green bowel movement.
Color Of Bowel Movement :
Feces can be of many different colors like black, red, brown, yellow, green and more. When you have diarrhea the color and texture of the stool would be totally different. You will have loose watery stool green or yellowish green color. The reason is simple. As said already food particles would pass through the intestine without full absorption. Bile needs quality time for acting on food molecules for breaking it down. Often the stool color would change if you have taken any new item in the restaurant. The food particles can take 1-3 days for complete absorption. Till that time part of food particles would remain in your intestine undergoing process of digestion. Sometimes there may not be any absorption in the intestine resulting in green bowel movement.
