What Causes Uremia?

Uremia is a condition in which a person has urea, one of the main components of urine, in their blood. This occurs when an excess of amino acids and the end products of protein metabolism enter the bloodstream instead of being excreted in the urine, as would happen normally. Uremia occurs when the kidneys have experienced damage. While they are generally responsible for filtering out toxins and bodily waste, malfunctioning or failing kidneys aren't able to accomplish this. The result is these products end up back in the bloodstream, which is damaging and potentially very dangerous for the body.
