Some strains of E. Coli are particularly aggressive – they cause the destruction and bleeding of the colon lining. As a result, there are traces of blood in the stool. The destruction of the lining opens a whole new world of problems for the patient; bacteria can break into the blood causing septicemia and sepsis. Besides severe water loss, the patient now faces blood loss as well.
Infections from such strains have a potential to trigger severe and even life-threatening complications, so if you have bloody stools it’s recommended to seek immediate attention of trained health professionals to find out the cause.
