The majority of people with significant rectal bleeding are elderly. Members of this population commonly have many other medical problems. As a result, they tend to suffer increased rates of illness and death.
In recent years, death from rectal bleeding has significantly decreased. This reduction is due to more efficient emergency departments, recent advances in procedures, and evolving surgical management.
The majority of complications from rectal bleeding occur when large amounts of blood have been lost.
The areas causing acute rectal bleeding
may rebleed. This underscores the need for making a definitive diagnosis and in discovering the source of the bleeding so that the corrective actions may be made.
Rectal bleeding with symptoms of weakness, dizziness,
or fainting is associated with at least 1 liter (2 pints) of blood lost
is a medical emergency. Seek medical care
immediately. Sudden loss of 2 liters (4.2
pints) or more of blood can be dangerous, if not fatal.
