Kidney health: 4 things to know

It’s important to live a healthy lifestyle to keep your kidneys going strong.

The kidney is the chemist of the body, said Dr. Brian Ewert, a Marshfield Clinic nephrologist. It keeps the body’s chemicals and fluid in balance and gets rid of waste products.

Discussing dialysis

Living a healthy lifestyle is important to maintaining kidney health. People who end up on dialysis, which is a treatment meant to mimic the function of the kidney, are often those with diabetes or high blood pressure.

“Most people with high blood pressure or diabetes won’t end up on dialysis,” Ewert said. “But most people on dialysis have one of those two diseases.”

Dialysis replaces kidney function but at only 10-15 percent of normal, Ewert said.

“The lifespan of a person on dialysis is half that of a person the same age who is not on dialysis,” Ewert said. “The survival rate of dialysis is worse than many cancers.”

Care of the kidney

Ewert said, once people have risk factors for kidney disease, they should eliminate red meat and salt from their diet as much as possible. A healthy, vegetable-based diet and regular exercise will help you avoid diabetes and high blood pressure, which in turn will help you avoid kidney disease.

Ewert said because of advances in medicine, the number of people with diabetes who get kidney disease has decreased dramatically over the years.

Alcohol does not cause kidney disease. Smoking may accelerate vascular disease, which can result in decreased blood flow to the kidney.

Defining kidney failure

Ewert said kidney failure occurs when the kidney falls to about 10 percent of its normal function. At about 60 percent of normal function, a person has chronic kidney disease.

“Kidneys are very quiet,” Ewert said. “People can get all the way to kidney failure, and they won’t have back pain, and they’ll still be passing urine. That can be confusing for people.”

Because kidneys are “quiet,” people who have risk factors for kidney disease should be seen by their primary care provider regularly.

“People can have a substantial loss of kidney function and not have any symptoms,” Ewert said.

Other kidney issues

Kidney stones, which are calcium buildups in the urinary tract, may be brought on by diets heavy in animal-based protein. Genetics also play a large role in determining who suffers from kidney stones. For those at risk, taking extra vitamin C or consuming foods high in oxalate also may play a role in forming stones.

Polycystic kidney disease occurs when multiple cysts develop inside the kidneys. This is a genetic disease. A person has a 50 percent chance of inheriting this disease if one parent has it, Ewert said. This disease may lead to kidney failure.

If you’re concerned about your risk for kidney disease, contact your primary care provider.
