Importance of Proper Kidney Function

What does the kidney do?

Kidneys are abdominal organs that have some main maintenance functions of the human body. When kidneys are not functioning properly toxins begin to build inside the body because of the kidney’s filtering properties. 

Some of their functions include: 
  • Removes waste from the body and extra fluid
  • Helps control blood pressure
  • Produces red blood cells
  • Promotes bone health by producing Vitamin D
  • Helps maintain pH levels in the body by balancing acids


  • Symptoms of Kidney Problems or Failure
  • Common Kidney Diseases or Conditions
  • Risk Factors

Some symptoms that the kidneys are not functioning well are:  

  • Breathlessness
  • Breath smells
  • Confusion
  • Fatigue
  • Itchiness
  • Lack of appetite
  • Muscle cramping
  • Poor sleep
  • Swollen face and/or feet
  • Very dark, brown, or bloody urine
  • Acute and chronic kidney disease
  • Fluid and electrolyte abnormalities
  • Hematuria (blood in the urine)
  • High blood pressure
  • Kidney stones
  • Proteinuria (protein in the urine)
  • Urinary tract infections
  • Diabetes
  • Family history of kidney problems
  • Heart disease
  • High blood pressure


There are a few tests that a physician can use to determine the state of kidney function within an individual:  

  • Blood test – determines how well blood is being filtered in the kidneys. It is called glomerular filtration rate or GFR. A GFR of 60 or more is healthy, while less than 60 could be a sign of kidney disease. Less than 15 is diagnosed with kidney failure.
  • Imaging
  • Removing a piece of a kidney to test
  • Urine test – tests levels of protein in the urine. The test specifically looks for a protein called albumin, which is released into the kidneys when the kidney is not functioning. A level of 30 mg/g or less is healthy, while anything more can be a sign of kidney disease.


A starting point for treating kidney issues are trying to treat the cause of the problem. That may require lifestyle changes or medications to treat for:

  • Anemia
  • High blood pressure
  • Lower cholesterol
  • Strengthen bones
  • Swelling
For end-stage kidney disease, more advanced and immediate treatment may be needed, which includes:
  • Dialysis – dialysis involves either using a thin tube, or catheter, inserted into the abdomen to fill the body with a solution to absorb waste and excess fluid, which then later drains from the body, or using a machine to filter waste from the blood.
  • Kidney transplant – a healthy kidney is surgically placed inside the body after removing a damaged one. Medication will then need to be permanently taken in order for the body to not reject the donor kidney.
