What Creatinine Level Signals Kidney Failure?

 

Every human being has creatinine in the blood, which is a body waste that comes from protein and muscle breakdown. It is removed through the kidneys. High amounts of creatinine may indicate issues in your kidneys. Let us know what level of creatinine affects your kidneys and leads to their failure.

 

How Much Creatinine is Bad for Your Kidney?

 

Low amounts of creatinine can be caused by poor muscle mass, whereas high levels in the blood may be a sign of renal dysfunction or kidney failure. The average creatinine levels in people can differ according to an individual's muscular mass, age, and sex. However, the average ranges for males are 0.7 to 1.2 milligrams per decilitre (mg/dL). The normal range of creatinine levels for females is also between 0.5 and 1.0. You can see the average normal range of creatinine in the table below:

 

LevelsAdult males (mg/dL)Adult females (mg/dL)
Low0.5 to 0.80.4 to 0.7
Average0.7 to 1.20.5 to 1.0
HighAbove 1.4Above 1.2

 

If the normal level of creatinine exceeds 1.4 in males and 1.2 in females in the test, it may indicate impaired kidney function. Similarly, if it goes below 0.8 and 0.7 in males and females, respectively, it is considered a low level, and the person is dealing with low muscle mass, liver disease and pregnancy. 

 

What are the Causes of High Creatinine Levels?

 

High creatinine levels signify that the kidneys are not functioning properly. Below are some of the main causes of high creatinine levels:

 

  • High Consumption of Protein : Creatinine is found in proteins and cooked meat, which can cause elevated creatinine levels after meals.
  • Chronic Kidney Disease : Creatinine levels rise when kidney disease occurs because the kidneys struggle to remove it from the blood.
  • Diabetes : High blood sugar levels can result in kidney disease and reduce their functioning capability.
  • Glomerulonephritis : It is a disease that causes inflammation in the kidney structures and stops the filtering of blood.
  • High Blood Pressure : High blood pressure can harm the blood arteries that supply the kidneys, which can impair kidney function and raise creatinine levels.

 

Treatment and Preventive Measures to Reduce Creatinine Levels

 

Depending on the cause of high creatinine, doctors can recommend taking certain medications and implementing changes to everyday habits. Below are some of the preventive measures that you must implement to stay away from renal dysfunction:

 

  • Exercise regularly.
  • Maintain a healthy diet with low fat and salt.
  • Avoid smoking.
  • Control your blood sugar levels.
  • Limit your alcohol intake.
  • Stay hydrated.

The serum creatinine test is conducted to check the filtration of the kidneys. If they are not functioning well, it may indicate higher levels of creatinine in the blood. Factors like high blood pressure, high blood sugar levels, high consumption of protein, and other chronic diseases can lead to high creatinine levels. Anyone who finds any symptoms related to this can seek medical advice.
