Preventing Kidney Disease is in Our Blood

Early symptoms and hints about kidney health often get overlooked, even though more than 26 million Americans have chronic kidney disease. Kidney damage typically occurs slowly over many years, often due to diabetes or high blood pressure and advancing age. Secondary risks include obesity, autoimmune diseases, urinary tract infections, and systemic infections. Like with most health issues and chronic diseases, awareness and early intervention are critical.

Our kidneys filter extra water and wastes out of our blood, and make urine. Kidneys also help control blood pressure, make red blood cells, help bone health, and create hormones that bodies need to stay healthy. Kidney disease means that the kidneys are damaged and can’t filter blood like they should. This damage can cause wastes to build up in the body and also cause other problems that can harm our health.

When it occurs slowly, damage to the kidneys is called chronic kidney disease. When someone has a sudden change in kidney function — because of illness, or injury, or because they have taken certain medications that may have harmed them — this is called acute kidney injury. It can occur in a person with normal kidneys or in someone who already has kidney problems.

Anyone can develop kidney disease, regardless of age or race. The main risk factors for developing kidney disease are:

  • Diabetes
  • High blood pressure
  • Cardiovascular (heart and blood vessel) disease
  • A family history of kidney problems

Early detection is very important, especially since you may not feel any different until your kidney disease is very advanced. Blood and urine tests are the only way to know if you have kidney disease. A blood test checks your glomerular filtration rate (GFR), which tells how well your kidneys are filtering. A urine test checks for protein in your urine. Both are simple tests your doctor can conduct or coordinate.

The sooner you know you have kidney disease, the sooner you can get treatment to help delay or prevent kidney failure. Treatment may include taking medicines called ACE inhibitors or ARBs to manage high blood pressure and keep your kidneys healthier longer. Treating kidney disease may also help prevent heart disease, since people with kidney disease are more likely to have a stroke or heart attack.

Kidney disease usually does not go away. Instead, it may get worse over time and can lead to kidney failure. If the kidneys fail, treatment with dialysis or a kidney transplant is necessary.

Here are 10 ways to help keep your kidneys healthy.

  • Exercise regularly or remain physically active as much as possible
  • Don’t overuse over-the-counter painkillers (NSAIDs such as ibuprofen and aspirin)
  • Cut back on salt;  read labels carefully and aim for less than 1,500 milligrams of sodium each day
  • Get an annual physical
  • Control your weight by following a healthful diet, and choose foods that are heart healthy, including fresh or frozen fruit and vegetables, whole grains, and low-fat dairy products
  • Know your family’s medical history
  • Monitor blood pressure, sugar, and cholesterol levels
  • Learn about kidney disease
  • Don’t smoke tobacco products or abuse alcohol — both can make kidney damage worse
  • Talk to your doctor about getting tested if you’re at risk for kidney disease
