The colon is part of the digestive system responsible in bringing waste materials from the small intestines to the rectum. It absorbs sodium and water from the waste after food passes through the intestines and then the waste is ready to be expulsed from your body. For the colon to perform its function effectively, it needs to be healthy otherwise negative impacts will be evident in food digestion and different other body processes that are essential. When toxins reach the colon from unhealthy drugs and foods, it may become clogged making it harder for it to function effectively. It is here that most people start experiencing bowel movement difficulties.
