High Creatinine Levels What They Mean and When to See a Nephrologist

Creatinine is a by-product of protein digestion and muscle metabolism and needs to be excreted from the body, via urine. High levels of creatinine are hence a tell tale sign of the kidneys not working normally. This is because its levels are usually maintained within a very narrow biological range. But, it is also important to understand that having higher than usual levels of creatinine does not always mean you have kidney damage. It may be due to some other cause altogether too.

If you notice signs like fluid retention, excessive fatigue along with poor creatinine level management, you should consult a renal function specialist at KIMS Sunshine Hospital right away!

Causes For High Creatinine Levels-

These are some well known elevated creatinine causes-

If you suffer from chronic kidney disease, kidney injury or glomerulonephritis or some other infection- all of which can negatively impact kidney function.
If you eat high amounts of protein rich foods, then your creatinine levels will be higher, but this is temporary for the most part.
If you don’t drink enough water.
If you use medications like NSAIDs, antibiotics or others which can affect kidney function.
If you suffer from diabetes, chronic hypertension or any vascular condition that can affect the blood vessels in the kidneys.

Symptoms Of High Creatinine Levels-

The following symptoms along with chronically high levels of creatinine in blood serum can point to kidney disease or some underlying condition that needs to be diagnosed and managed. This is also when you should go in for chronic kidney disease evaluation, sooner rather than later.

Swelling due to fluid retention or edema in the extremities is a common issue- and it normally affects the region around the eyes, face, ankles and legs.
You may feel very tired all the time.
You may feel like peeing more often, while the urine may seem foamy or smell different. It may be darker in colour than usual too.
You may feel more confused than usual- this is due to the accumulation of toxins, which can alter brain function.
You may not have much of an appetite and may feel nauseous.
You may feel itchy or observe dry skin.

Diagnosis and Treatment For High Creatinine Levels-

Blood tests are routinely used to check for creatinine levels in serum. Creatinine clearance test is a specialized test that is used to check how much creatine is broken down to form creatinine, in 24 hours. Both urine and blood samples are hence taken within this window. But, it can be inconvenient to collect so many samples over a day’s time, so doctors don’t recommend this test as often these days.

An eGFR test is just as useful and can help determine the glomerular filtration rate per minute of the kidney. Any value below 30 can mean you will need definite intervention in the form of medications and dialysis. A value of 99 and above is normal. Any lower, and doctors will begin to use a grading system to check how much damage your kidney has sustained.

In very rare cases, doctors may ask for a kidney biopsy done.

Treatment includes managing blood pressure properly, eating a low protein and low sodium diet, drinking enough water and eating a balanced diet and getting dialysis to help reduce load on the kidneys respectively. If your eGFR value is below 15, then it is kidney failure and you may need to consider getting a transplant.

Conclusion

if you have any of the abovementioned symptoms or suffer from chronic diabetes and hypertension, please make sure to take good care of your kidneys and heart. When your kidneys are no longer able to support you well, please consider talking to a dialysis consultation nephrologist from KIMS Sunshine Hospital, as we have the best specialists in the city.

Frequently Asked Questions

When should high creatinine levels be evaluated by a nephrologist?

High creatinine levels should be evaluated if they remain persistently elevated, worsen over time, or are associated with symptoms such as swelling, fatigue, reduced urine output, high blood pressure, or shortness of breath. Early nephrology evaluation helps identify kidney dysfunction and prevent further complications.

Which tests are done to assess kidney function?

Doctors may recommend serum creatinine testing, blood urea levels, estimated glomerular filtration rate (eGFR), urine analysis, kidney ultrasound, electrolyte testing, and sometimes kidney biopsy to evaluate kidney function and identify underlying kidney disease.

Does high creatinine always indicate kidney failure?

No, high creatinine does not always indicate kidney failure. Elevated creatinine levels may occur due to dehydration, certain medications, muscle injury, urinary obstruction, or temporary kidney stress. However, persistent elevation requires medical evaluation to rule out chronic kidney disease or significant kidney dysfunction.

When is dialysis required for kidney disease?

Dialysis may be required when kidney function becomes severely impaired and the kidneys can no longer effectively remove waste products and excess fluid from the body. It is commonly recommended in advanced kidney failure, severe electrolyte imbalance, fluid overload, or life-threatening complications of kidney disease.

Can uncontrolled diabetes or blood pressure increase creatinine levels?

Yes, uncontrolled diabetes and high blood pressure are major causes of kidney damage and can lead to elevated creatinine levels over time. Proper management of blood sugar and blood pressure helps protect kidney function and reduces the risk of chronic kidney disease progression.
