What is Dialysis and Chronic Kidney Disease

It is estimated that more than 31 million American adults have chronic kidney disease (CKD). However, a survey done by the National Medical Association and Amgen shows that most adults know very little about the symptoms or treatment of the disease.

How can people be so unaware of a disease that affects so many? Like diabetes and high blood pressure, chronic kidney disease is called a “silent killer” because there are few symptoms and by the time a person realizes they have a problem, much damage has already been done.

By sharing information you can help save lives. Because chronic kidney disease happens over time, creating awareness and encouraging people to get their kidney function checked regularly may give them the opportunity to slow the progression of the disease and perhaps even prevent kidney failure. It’s time to spread the word about kidney disease.

How do normal kidneys function?


To understand how chronic kidney disease can go unnoticed, let’s take a look at how normal kidneys function and then learn how efficiently they can work even when they are damaged.

Most people are born with two kidneys. The kidneys are about the size of a closed fist. They are located in the middle back above the waist, with one on each side of the spine. The right kidney is a little lower and smaller to make room for the liver.

Most people think that the kidneys are only responsible for making urine, but there are more functions of the kidneys that affects many areas of the body.

A health kidney is responsible for:

cleaning the blood

producing urine

regulating blood pressure

balancing fluids, minerals and chemicals in the body

signaling the bones to make red blood cells

Healthy kidneys process all of the body’s blood supply every five minutes. On a daily basis healthy kidneys filter the blood, removing toxins from the bloodstream and turning it into urine that will be excreted from the body. In addition, the kidneys release renin, which is an enzyme that regulates blood pressure. The kidneys also decide when to hold on to or delete fluids, minerals and chemicals in the body to keep levels balanced and healthy. Another task of the kidneys is to signal the release of erythropoietin, a hormone that tells the bones to create red blood cells.
