Streaks of blood in stool: Type of rectal bleeding

There are two possible sources of blood in the stool: the upper digestive tract (stomach and intestine hail) and the lower gastrointestinal tract (colon, rectum, and anus).

Hemorrhage of the top gastrointestinal tract usually causes black tarry stools.
Bleeding in the lower digestive tract is usually seen because stools are coated or mixed with bright red blood.

Some foods and medications can cause blood in the stool.
However, it is not always possible to know the origin or type of rectal bleeding by stool appearance.

Sometimes the amount of blood is small and can be seen only on toilet paper.
A physical examination and assessment by the doctor are necessary in most cases.
Sometimes, hemorrhages in the gastrointestinal tract may be too slow to cause rectal bleeding.

In these patients, the bleeding is occult (not visible to the naked eye). Blood is found only through stool analysis (fecal occult blood test) in the laboratory.
Occult bleeding has many causes similar to rectal bleeding and can cause the same symptoms. They have often associated anemia that is due to the loss of iron in the blood (iron deficiency anemia or iron deficiency anemia).
