A decrease in creatinine levels is generally indicative of an improvement in kidney function. Creatinine is a byproduct of muscle metabolism that is typically removed from the body through the kidneys.
If the kidneys are not functioning properly, then creatinine will not be removed efficiently, leading to high levels of creatinine in the blood. A decrease in creatinine would then reflect the kidneys’ improved ability to filter creatinine from the bloodstream, which is a positive sign of increased kidney functioning.
However, it is important to note that a decrease in creatinine levels is not always indicative of improved kidney functioning, and should be monitored by a physician to ensure that the kidneys are indeed functioning correctly.
In some cases, a decrease in creatinine can occur as a result of decreased muscle mass or an increased amount of water in the body, as both of which can cause an artificial decrease in creatinine levels in the blood.
Dehydration can also cause a decrease in creatinine, as the body retains water in order to balance things out if there is not enough water in the system. Therefore, it is always important to monitor creatinine levels in order to ensure that the body is functioning properly.
Should I worry if my creatinine is low?
It depends. Low creatinine can be normal or it can be an indication of an underlying health issue. If the person is an athlete who participates in activities such as weightlifting, the creatinine concentration in the blood may be lower than normal due to the athlete’s increased muscle mass.
Creatinine levels below the normal range may also be seen in vegetarians or in people with liver disease, kidney disease, or malnutrition. If you’re experiencing symptoms such as fatigue, muscle weakness or cramping, or enlarged muscles, your creatinine levels should be checked.
Consulting with a healthcare provider is important to determine if the levels are lower due to normal hormonal action or if there is an underlying health concern. Your healthcare provider will be able to provide you with further guidance on how to address the issue.
What level of creatinine indicates kidney failure?
A creatinine level of 2.0 mg/dL or higher indicates kidney failure. When creatinine levels increase above 2.0 mg/dL it is a sign that the kidneys are unable to efficiently filter toxins, waste and other metabolic byproducts from the body.
Generally once creatinine is elevated to this level an individual will be referred to a nephrologist for further assessment. Other tests, such as a urine analysis, CT scan or ultrasound may be ordered to determine the underlying cause of kidney failure.
Treatment options may vary depending on what is causing the creatinine levels to rise and could include dialysis, medications and/or lifestyle changes.
