Can constipation be a warning sign of a more serious condition?
Very rarely, constipation is a sign of a more serious condition. Constipation with pain or bleeding when passing a stool could be a warning sign of colon cancer, especially in people over 50 years of age, but it is also a sign of having haemorrhoids (piles). Being unable to pass a stool or gas, with cramping pain, may be a sign of an intestinal obstruction. Always tell your doctor about any pain, bleeding or bloating, especially if it lasts for more than two weeks.
