Blood in Stools
In some severe cases, diverticulitis would lead to blood in the stool. When the tissues or walls around the colon are inflamed seriously, bleeding might occur in the bowel and make the stools look black or tarry. It is extremely important to visit your healthcare provider immediately as this is an advanced symptom that indicates the progression of bacteria to a larger area. Otherwise, the whole digestive system would be affected with more serious consequences. [2]
