In upper digestive system bleeding, blood mixed with a pitch black stool called melena is seen. It smells very bad. However, sometimes abundant bleeding in the upper digestive tract may appear red from the anus. This severe bleeding passed directly through the intestines without being digested. This type of bleeding is accompanied by weakness, paleness of the face, darkening in the eyes and dizziness due to low blood pressure. The patient cannot stand. The shape and color of the bleeding in the digestive system at the level of the large intestine varies depending on the amount of bleeding. In moderate bleeding, the blood is either mixed with feces or pure blood. The blood is in the form of fresh blood and clotted. This situation generally occurs in tumor bleeding. Continuous bleeding causes anemia, weakness, fainting and palpitations in the patient. Such patients must be hospitalized, undergo endoscopy to find the focus of bleeding, and receive the necessary blood supplements.
The color of bleeding that occurs from the last part of the large intestine, just above the anus, is red. It is a bright red bleeding. It comes either mixed with the stool or in drops after defecation. It gets on your hands while you are urinating or on the napkin while you are drying yourself.
