What Are Renal Complications?

Renal refers to anything involving, relating to or located in the region of the kidneys. Renal complications are a diminished function of the kidneys, up to and including renal failure (known as kidney failure).


According to the National Kidney Foundation, there are five stages of renal complications, ranging from kidney damage (when the kidneys function at or above 90 percent) to kidney failure (when they function is less than 15 percent).


Without fully functioning kidneys to rid the body of waste, toxins build up in a person’s blood, causing other organs to fail.

Detecting Renal Complications


One-third of all American adults are at risk for kidney disease, according to the National Kidney Foundation. However, early detection and treatment can slow renal complications.


Your body experiences problems from the early stages of renal complications, even if you are not experiencing nausea, vomiting, swelling and fatigue generally associated with kidney failure. A simple urine test can reveal the state of your kidneys.


Protect yourself by learning the indicators of renal complications.

People with a Higher Risk

Family history, diabetes, high blood pressure and age (60 years and above) can increase your risk of renal complications. If you fall into any of these categories, speak with your doctor about your renal health.

Know Your Family History

The biggest indicator of kidney disease is a genetic predisposition. If you have a family history of renal complications, make sure you receive regular checkups from a doctor who is aware of your history.

Monitor Your Blood Pressure

If you suffer from high blood pressure, monitor it closely. To reduce the chance that your blood pressure will negatively affect your kidneys, speak to your doctor about adjusting your diet. Doctors usually recommend a low sodium, low-protein diet and high water intake.

Other Indicators

When you see a doctor to test for renal complications, they will test for protein in your urine as this is a sign of diminished kidney function. Foamy urine is an indicator of protein in your urine. Repeat urinary tract infections or a history of renal stones can also indicate poor kidney function.

Disease Associated with Renal Complications

Lupus, sarcoidosis, rheumatoid arthritis, gout, hepatitis B and hepatitis C are all diseases associated with renal compilations. If you suffer from any of these diseases or suffer from malignant diseases in the renal area, have your renal health monitored regularly.
