AIDS phobia is loosely defined as the irrational fear of getting infected with HIV or the fear you have already been infected despite evidence to the contrary. 1  it's condition that may be easy to dismiss or denigrate, but one that a person rarely gets over without some sort of focused intervention.
Urea, also called carbamide, is an organic chemical compound, and is essentially the waste produced by the body after metabolizing protein. Naturally, the compound is produced when the liver breaks down protein or amino acids, and ammonia; the kidneys then transfer the urea from the blood to the urine.
Urea nitrogen is a normal waste product that your body creates after you eat. Your liver breaks down the proteins in your food -- and while it does that, it creates blood urea nitrogen, also known as BUN. Your liver releases the substance into the blood, and it eventually ends up in your kidneys. When your kidneys are healthy, they remove the BUN, usually leaving a small amount of it in the blood.
