The levels of creatine in your body will change based on many factors, including diet, exercise, medications, and overall stress levels. Creatine is a molecule found within the body and is developed simply by the food that you consume. This food turns into energy as it metabolizes.
Creatinine is made through the breakdown of the creatine, and it then travels to your kidneys through the bloodstream. Extraordinary high levels of creatinine can be a major health concern and would need to immediately be treated by a health care professional.

Yes, the creatinine levels of the body are a direct result of your overall muscle mass. Traditionally, creatinine levels in a man are higher than creatinine levels in a woman.
The primary reason for this is the amount of muscle mass in a man is greater than in a woman. Other direct factors related to creatinine levels include your age and your body weight.
The older you get, the lower your overall level of creatinine. In addition, if you are extremely overweight, your level of creatinine will be lower as well. Thank you so much Doctor.

When your muscles break down during exercise, they slowly build back up, increasing muscle mass, but this process also releases waste products into your blood, primarily creatinine. Everyone has certain serum creatinine levels in their bloodstream. Creatinine is a natural byproduct of muscle use, caused by the breakdown of a chemical called creatine.
So, how does your body generate creatinine? It starts with creatine, which is synthesized in the kidneys, pancreas, and liver, then transported via blood flow and stored in your skeletal muscles. During exertion, your muscles convert creatine to energy, which assists in muscle contraction. After serving its purpose, creatine becomes creatinine and re-enters the bloodstream en route to the kidneys.
For this reason, physicians will often use a creatinine test—along with other lab tests, like a blood urea nitrogen BUN test—to monitor for chronic kidney disease CKD or renal failure. In most cases, the normal range for serum creatinine found in the blood for someone with healthy kidneys is 0. However, there are a lot of variables when it comes to levels of creatinine. Muscle breakdown creates creatinine, so your muscle mass and activity level can influence the amount in your blood.
To accurately measure blood creatinine levels, a doctor will first assess these various factors to establish a baseline, according to Taylor Graber, MD, an anesthesiologist and founder of ASAP IVs. Graber says. Once these values are normalized, changes from this range can signify abnormalities of the kidney. Healthcare providers like to keep an eye on creatinine levels for various reasons. If you had or currently have kidney disease, kidney damage, diabetes , or another illness that affects your kidneys, or are taking a medication that could affect your kidneys, your healthcare provider might order regular creatinine measurement to monitor your renal function.
The most common test methods are via blood and urine. Creatinine that comes from your blood is called serum creatinine, and it can be measured by administering a routine blood test. Graber explains.
