Symptoms of an unhealthy colon include diarrhea, constipation and chronic flatulence, according to the Alive Publishing Group. Other symptoms that can signal an unhealthy colon include allergies, headaches, illnesses that recur and sudden breakouts.
The colon is not working correctly if some type of bowel movement does not occur about 18 hours after a meal, reports the Alive Publishing Group. The colon, also known as the large intestine, receives food matter that has been processed by the small intestine for the final part of the digestion and elimination process. A healthy colon requires good nerve and muscle tone and proper nutrition and hydration. If the colon is not healthy, it begins to slow down the process of digestion or fails to work.
Waste that remains in the body is toxic. Its reabsorption over long periods can have many deleterious effects on the body. A good portion of chronic and degenerative diseases are a result of a colon that is not functioning optimally. Such conditions include many forms of cancer, chronic fatigue syndrome, arthritis and many autoimmune diseases.
To maintain a healthy colon, an individual should consume a significant amount of fruits and vegetables, exercise regularly and keep properly hydrated at all times. If a person is experiencing symptoms that indicate an unhealthy colon, he should consult a medical professional.
