Studies show serum creatinine concentrations can steadily increase with age, particularly after age 60 for men and age 40 for women. But what does this mean for your health? This guide explores the question: Does creatinine get higher with age?
According to the Lifespan Research Institute, plasma urea concentrations typically increase by about 60% between the ages of 20 and 80. This natural, gradual rise is a common physiological change, but understanding **why does urea concentration increase with age** is crucial for distinguishing normal aging from potential health issues.
As the body ages, changes in muscle mass and kidney function affect lab results, including creatinine. For a 70-year-old, a normal creatinine level is often viewed differently than in a younger adult, and relying on population-wide norms can be misleading without proper context.
