What is the normal value of blood urea?

The normal value of blood urea is very important for evaluating kidney function and body metabolism. Generally, the normal range of blood urea nitrogen (BUN) is 7 to 20 milligrams per deciliter (mg/dL). However, this range may vary slightly from laboratory to laboratory, so doctors usually combine other indicators to fully evaluate health status.

Knowing the normal value of blood urea can help us pay attention to our own health. Urea is a product of protein metabolism, mainly produced by the liver and excreted from the body through the kidneys. If the blood urea level is too high, it may mean that the kidneys cannot effectively excrete urea from the body. This situation may be related to factors such as impaired kidney function, dehydration, heart failure, etc. Sometimes, excessive protein intake in the diet can also lead to increased blood urea. On the contrary, if the blood urea level is too low, it may be caused by impaired liver function, malnutrition or overhydration.

In daily life, we can maintain blood urea within the normal range in some simple ways. Maintain a balanced diet, consume protein in moderation, and avoid excessive consumption of high-protein foods. Pay attention to replenishing enough water to help the kidneys effectively eliminate metabolic waste. Have regular physical examinations to keep abreast of your blood urea levels and kidney function status so that you can take measures as soon as possible when abnormalities occur.

Changes in blood urea levels may be related to a variety of factors, so when interpreting blood urea test results, other clinical indicators and personal health conditions should be considered. It is recommended that you communicate with your doctor after the physical examination to understand the specific meaning of the test results. If you find that your blood urea level is abnormal, don't panic. The doctor will give you reasonable advice and treatment plans based on the specific situation.

Understanding the normal value and influencing factors of blood urea can help us pay more attention to our own health. Through a reasonable lifestyle and regular physical examinations, we can effectively maintain kidney health and ensure the normal functioning of various body functions. I hope this article can provide you with useful information and help you better understand the importance of blood urea testing.
