High or Elevated Creatinine: Causes, Symptoms, Side Effects, Diagnosis, Treatment and Preventive Tips

It is known as an end product of metabolism, which is a chemical waste created by the metabolic activities of the muscles.

The primary source of creatinine is creatine, an important molecule that helps produce energy for muscles.

About 2% of the creatine in your body is converted to creatinine daily and transported to the kidneys through the bloodstream. And your kidneys filter most of the creatinine and remove it from your body through your urine.

Remember, a low urine creatinine level can indicate high blood creatinine levels, but it is not of great concern in most cases.

Below is a creatinine level chart that reveals normal and abnormal creatinine ranges based on age, gender, muscle mass, etc.

Creatinine levels graph

Creatinine levels in your body generally depend on muscle mass, gender, age, and other health factors. They are often measured in milligrams per deciliter:


Adult men 0.6 a 1.2 mg / dl

Adult women 0.5 a 1.1 mg / dl

Infants 0.2 mg / dl

For individuals with only one kidney, 1.8 a 1.9 mg/dl

Older people have lower creatinine levels than average adults, and bodybuilders can have higher creatinine levels than most adults.


Older people have diminished muscles, while bodybuilders have more power than ordinary people.

Additionally, people with muscle-related disorders may have creatinine levels significantly lower than those indicated for their age and gender.

What Causes Elevated Creatinine?

If your kidney function is disrupted or impaired by a condition, it can cause your creatinine levels to rise.

Some of the more common causes of chronic kidney disease or elevated creatinine levels in adults include:

  • High blood pressure
  • Urinary tract infections
  • Kidney infections
  • Abnormal muscle destruction as a result of rhabdomyolysis.
  • Drugs such as cimetidine.
  • Consume large amounts of dietary meat.

What are the symptoms of high creatinine?

Symptoms of high blood creatinine levels and kidney dysfunction often vary widely and may not be correlated with each other.

Some people may have severe kidney disease and elevated creatinine levels without showing any symptoms, while others often develop symptoms such as:

  • Swelling or edema
  • Short of breath.
  • Dehydration
  • Nausea and vomiting
  • Confusion.

It is essential to diagnose your kidneys periodically if you have high creatinine levels.


If your blood test reveals that you have elevated creatinine levels, you may undergo the following tests:

  • Blood urea nitrogen test: This test checks how well your kidneys work by measuring the amount of urea nitrogen in your blood. Too much or too little urea nitrogen often hints at kidney problems.
  • Basic Metabolic Panel Test – This is a combination of tests that assess essential bodily functions.
  • Complete Metabolic Panel Test: This test is a neat panel of 14 trials, giving your doctor important information about the health of the kidneys, liver, electrolyte and acid/base balance, etc.

These are some standard tests to diagnose high blood creatinine levels.

Side effects of elevated creatinine

High blood creatinine can pose the following dangers:

  • It causes more damage to your kidneys.
  • It increases your risk of developing cardiovascular disease.
  • It leads to digestive and respiratory system disorders.
  • It causes problems with your nervous system.

If left unattended, high creatinine levels can threaten your overall health. Therefore, it is important to test regularly to nip the problem in the bud.

Although all the remedies mentioned in this article are pretty helpful in reducing high blood creatinine levels, it is best to consult your doctor before trying any of them.
