What are the complications of internal bleeding?

Where and How bad? The answer to this could be anything from no complications to death. Blood within the vascular system is the lifeline for every cell in the body. Anytime you are losing more blood than your body can manufacture you become anemic (low red blood cells). Once your blood counts get down to 1/4 to 1/3 of normal you are at great risk of high output heart failure, under-perfused organs, shock, and death.
