Why would your BUN level increase when you have a disease?

Select one of the following:

Because the kidneys are not functioning at full capacity and are unable to clear the nitrogen from your system properly
during a disease there is a significant number of cells that are damaged and dying. They are made up of proteins which is a nitrogenous waste and thus your BUN will rise.
during the disease process the inflammatory process produces greater amounts of nitrogen therefor increase blood nitrogen levels.
your BUN will not increase when you have a disease.
