Bloody Stool
Just like other conditions with your digestive system, another common sign of colitis is bloody. This disease would cause open ulcers or sores anywhere in the digestive tract. Unfortunately, these ulcers could bleed and lead to rectal bleeding. Blood or pus could appear on or in the stool, making it look like coffee grinds. In some cases, you might only pass blood. Since it is often a very serious sign, it is important to see your doctor or healthcare provider as soon as possible. This is especially true when the illness is followed by other symptoms mentioned above. [5]
