Nobody like likes to talk about it, but the fact remains that a large, healthy bowel movement is highly satisfying as well as important for your health. In case you don’t have regular bowel movements, or in case your stools are hard, odd colored, or it is difficult to pass them, it means that your colon is unhealthy. Other facts are that constipation, gas, diarrhea, bloating, as well as a large belly and bad breath are signs of a unhealthy colon. Then there are the less obvious signs of a distressed colon such as tiredness, problem in concentrating, headaches, varicose veins, hemorrhoids as well as bloodshot eyes.
