It is a test in which the waste products formed during the breakdown of proteins in the body accumulate in the blood as a result of processing by the kidneys. Blood urea nitrogen (BUN) is formed through the conversion of ammonia produced by the liver into urea, which is produced by the kidneys.
Blood urea nitrogen The test is used to evaluate kidney functions, monitor electrolyte balance and determine the functional capacity of the kidneys.
However, there are many conditions that cannot be diagnosed with the BUN test alone, and therefore physicians make a diagnosis by evaluating the patients' clinical picture and other test results.
Although normal BUN levels vary by laboratory, they are generally between 7-20 mg/dL.
Low BUN levels may indicate liver function problems, excessive fluid intake, pregnancy, some chronic liver diseases, nutritional deficiencies, or chronic kidney diseases. Blood urea nitrogen Low BUN is not usually considered a serious health problem, but underlying causes may need to be treated.
Treatment may vary depending on the underlying cause, and lifestyle changes or medications may be recommended based on your doctor's recommendations. People with low BUN are advised to follow up regularly with their doctor.
High BUN levels can indicate kidney function problems, dehydration, kidney infections, urinary tract obstructions, heart failure, and side effects of certain medications. It can often occur for a variety of reasons, including kidney disease, heart failure, dehydration, urinary tract infections, medication side effects, or nutritional deficiencies.
Treatment for elevated BUN levels begins with identifying and treating the underlying cause. For example, if elevated BUN levels are caused by kidney disease, the cause of the kidney disease must first be determined and then appropriate treatment methods implemented. Treatment may include a variety of methods, including dialysis, medication, dietary changes, or surgery.
Elevated BUN due to dehydration is usually treated with simple treatments such as increasing fluid intake or giving intravenous fluids.
Additionally, if BUN is elevated due to side effects of medications, the medication dosage may be adjusted or the medication may be replaced entirely.
Elevated BUN levels due to nutritional deficiencies can be treated with a suitable diet program or support from a dietitian. This can include making changes such as avoiding high-protein foods or limiting protein intake.
As a result, treatment, blood urea nitrogen It aims to protect the healthy functions of the kidneys, heart and other organs by ensuring that (BUN) levels fall to normal levels.
