Feeling confused by your recent lab results? You're not alone! BUN (Blood Urea Nitrogen) and creatinine levels are common tests to assess kidney function, but understanding what they signify can be tricky.
Think of your kidneys as your body's waste filtration system. BUN is a waste product from protein breakdown, while creatinine is a waste product from muscle metabolism. Elevated levels of either can indicate your kidneys aren't filtering waste as efficiently as they should.
High BUN/creatinine levels can be caused by various factors, including dehydration, certain medications, kidney disease, or even a diet high in protein. Conversely, low levels are less common but can be linked to liver disease or malnutrition.
It's important to remember that BUN/creatinine levels are just one piece of the puzzle. A single abnormal result doesn't automatically mean you have kidney disease. Your doctor will consider these results alongside your medical history, symptoms, and other tests to determine the best course of action. If you have concerns, always discuss your results with a healthcare professional for personalized advice.
