High creatinine levels can indicate, in fact, a range of underlying health conditions, including, for example, kidney infection and kidney failure. Doctors typically consider high creatinine levels to be, specifically, above 1.2 milligrams per deciliter (mg/dL) for males and 1.0 mg/dL for females.

Creatinine is, in essence, a waste product of the muscles. In a healthy body, the kidneys filter creatinine from the blood and, consequently, excrete it through the urine. Therefore, high levels of creatinine can indicate kidney issues.

Moreover, it is important to note that creatinine is a by product of normal muscle function. In particular, it is a metabolite of creatine phosphate, which the muscles use as an energy source.

Furthermore, the greater someone’s muscle mass, the higher, naturally, their creatinine levels. For this reason, males tend to have, on average, higher creatinine levels than females.

The primary way in which the body removes creatinine from the blood is, ultimately, by filtration through the kidneys and then excretion in the urine.

What is Creatinine? Causes and Symptoms

What are Normal and High Creatinine Levels?

The creatinine levels that experts consider to be normal may vary, indeed, among different hospitals and laboratories.

According to the British Medical Journal, the usual reference range for serum creatinine is, generally speaking, 60–110 micromoles per liter (mcmol/l), or 0.7–1.2 milligrams per deciliter (mg/dl), for males and 45–90 mcmol/l (0.5–1.0 mg/dl) for females.

If creatinine is above these levels, doctors may consider it high.

However, their decision will depend on someone’s muscle mass and certain other factors, such as age, sex, and hydration levels.

Creatinine Level Tests

Doctors take a blood sample to test creatinine levels. They then use a formula to estimate creatinine clearance.

In some cases, however, they may also request that the individual collects all of their urine over 24 hours and brings it to the laboratory.

Consequently, the doctor can then compare the urinary creatinine level with that of the blood. These results, therefore, show how much creatinine the kidneys are filtering out of the body and how well they are functioning.

Causes of High Creatinine Levels

High creatinine levels usually indicate that the kidneys are not working as they should. Specifically, possible causes of this dysfunction include:

Additionally, outside of kidney function, several other factors can temporarily raise creatinine levels above normal. For instance, these include pregnancydehydration and consuming large amounts of protein, either through food sources or nutritional supplements.

Moreover, high-intensity exercise can also increase certain blood biomarkers, including creatinine.

Finally, a person undergoing a creatinine test should let the doctor know if they are taking any medications, fasting, or adhering to a protein-rich diet.

Certain medicines can cause a temporary increase in serum creatinine levels or damage the kidneys.

Some health conditions can also damage these organs, leading to increased creatinine levels. These conditions include:

Symptoms

People with high creatinine levels may experience different symptoms. However, these symptoms depend on the cause.

Drug Toxicity

For instance, antibiotics, cardiovascular drugs, diuretics, and some other medications can cause kidney damage and affect how well the kidneys function.

Consequently, the symptoms include:

Kidney infection (pyelonephritis)

Moreover, an untreated kidney infection can damage the kidneys; in extreme cases, it can even cause kidney failure.

As a result, people may experience the following symptoms:

  • First, fever or chills
  • Second, pain in the back, side, or groin
  • Moreover, cloudy, dark, bloody, or foul-smelling urine
  • Furthermore, frequent, painful urination
  • Finally nausea and vomiting

Glomerulonephritis

In addition, lupus, Goodpasture’s syndrome, and infections can cause glomerulonephritis, which can lead to kidney damage and failure.

Thus, Possible symptoms include:

  • First, high blood pressure
  • Second, decreased urine output
  • Moreover, flank pain
  • Furthermore, blood or protein in urine (proteinuria)
  • In addition, bubbly or foamy urine due to high levels of protein
  • Lastly, swelling of the ankles and face

Diabetes

“In people with diabetes, blood sugar levels can become too high, leading to health problems, including kidney disease.

Furthermore, the symptoms of type 1 diabetes may develop suddenly; however, the symptoms of type 2 diabetes tend to present more gradually.

In both types of diabetes, symptoms may include:

High blood pressure

In fact, high blood pressure measurements show that the force of blood against the walls of the arteries is too high.

Moreover, high blood pressure can damage the blood vessels that perfuse the kidneys, affecting kidney function and, in turn, causing high creatinine.

Notably, many people with high blood pressure experience no symptoms; thus, doctors may only detect the issue during a regular health screening.

Heart disease

Additionally, heart disease is another concern.

Specifically, atherosclerosis, congestive heart failure, and other conditions that affect the heart can also affect kidney function.

The symptoms of heart disease depend on the specific type of this condition; however, they may include:

Atherosclerosis, congestive heart failure, and other conditions that affect the heart can also affect kidney function.

The symptoms of heart disease depend on the specific type of this condition, but they may include:

  • First, chest pain (angina)
  • Second, shortness of breath
  • Also, nausea
  • In addition, fatigue and weakness
  • Likewise, irregular heartbeat (arrhythmia)
  • Swelling, in the legs or feet

Urinary Tract Blockage

If the urinary tract becomes blocked by kidney stones, tumors, or an enlarged prostate, urine can accumulate in the kidneys; consequently, this leads to hydronephrosis.

Symptoms can include, for example:

  • First, pain in the back or side
  • Moreover, nausea and vomiting
  • Furthermore, painful urination
  • Also, blood in the urine
  • Next, fever

Kidney failure

Kidney failure, in other words, means that the kidneys have stopped working. It can be either acute, with symptoms that come on quickly, or chronic, with symptoms developing over time.

Therefore, people should watch for these symptoms, which could indicate acute kidney failure:

 
  • First, swelling in the feet and ankles
  • Second, too much or too little urine
  • Third, breathing problems
  • Also, nausea and vomiting
  • Moreover irregular heartbeat
  • Furthermore, confusion
  • Finally, weakness

On the other hand, the following symptoms may be present if kidney failure is chronic:

Treatment

Anyone experiencing any new and unexplained symptoms should consult a medical professional. Moreover, it is particularly important to seek advice if the symptoms indicate kidney disease, diabetes, or heart problems.

In addition, seeking prompt medical advice and treatment can prevent a health issue from becoming more severe.

Furthermore, the treatment for high creatinine levels depends on the underlying cause.

For instance, when a kidney infection is responsible for high creatinine levels, treatment with an antibiotic should return them to normal.

Likewise, if the increased creatinine levels are due to high blood pressure, taking medication to treat this should also lower creatinine levels.

Additionally, depending on the cause, doctors may also recommend making changes to everyday habits, such as reducing protein intake and increasing dietary fiber. Consequently, such adjustments may help someone manage their creatinine levels.

Outlook

The outlook for people with high creatinine levels varies depending on the cause.

In particular, for those experiencing a temporary increase in creatinine levels, any symptoms should usually resolve quickly after suitable treatment of the underlying condition.

Furthermore, individuals who can successfully control their diabetes or high blood pressure should also notice a positive effect on their kidney health and creatinine levels.

On the other hand, if someone has kidney failure, they may need medications and dialysis treatments to filter toxins and waste products from the blood. Ultimately, if end stage renal disease occurs, a doctor may also recommend a kidney transplant.
