BUN Full Form

Full Form of BUN

Blood urea nitrogen (BUN) measures the amount of urea in the blood. Urea is a waste product produced when the body breaks down protein. BUN measures how well the kidneys are working to remove waste from the blood.

A high BUN level may indicate that the kidneys are not working well. A low BUN level may indicate that the kidneys are not working well or that the person is not eating enough protein.

    Causes for the Increase in BUN:

    There are many potential causes for increased blood urea nitrogen (BUN). Some of the most common causes include dehydration, renal failure, and congestive heart failure.

    Dehydration can be caused by many things, including excessive exercise, vomiting, and diarrhea. When the body becomes dehydrated, it signals the kidneys to conserve water. As a result, the kidneys produce less urine, and the BUN level rises.

    Renal failure is a condition in which the kidneys no longer function properly. This can be caused by many things, including kidney disease, high blood pressure, and diabetes. When the kidneys fail, they can no longer remove waste products from the blood. As a result, the BUN level rises.

    Congestive heart failure is a condition in which the heart cannot pump enough blood to meet the body’s needs. This can be caused by many things, including coronary artery disease, heart attack, and high blood pressure. When the heart fails, the body becomes congested. This congestion can cause the BUN level to rise.
