High Blood Pressure & Kidneys


There are five stages of kidney disease. They are shown in the table below. Your treatment is based on your stage of kidney disease. Speak to your healthcare provider if you have any questions about your stage of kidney disease  or your treatment.



Glomular Filtration Rate (GFR)


Kidney damage (e.g., protein in the urine) with normal

90 or above


Kidney damage with mild decrease in GFR

60 to 89



Moderate decrease in GFR

30 to 59



Severe reduction in GFR

15 to 29



Kidney failure

Less than 15

There are usually no signs or symptoms that your blood pressure is too high. It is important to have your blood
pressure checked on a regular basis, especially if you have a family history of the disease or are at risk for other

Facts About High Blood Pressure?

It is called a “silent killer” because you can have it for years without knowing it.

It is a leading cause of heart attacks, strokes, and chronic kidney disease.

Controlling high blood pressure reduces the risk.

High blood pressure can often be controlled by losing excess weight, exercising more, not smoking, and cutting down on salt.

Blood pressure is measured with a blood pressure cuff that is wrapped around your upper arm. The person taking your blood pressure (you can learn to do it yourself) pumps air into the cuff and then slowly lets it out while listening for the sound of your pulse. The top number in your blood pressure reading is called the systolic pressure and the bottom number is called the diastolic pressure. For example, a reading might be 120/80, which is said as “120 over 80.” The top number is the pressure when your heart beats. The bottom number is the pressure when your heart rests between beats.

High blood pressure (hypertension) occurs when the force of your blood against your artery walls increases
enough to cause damage. A diagnosis of high blood pressure should always be confirmed on followup visits to
your healthcare provider.

What causes high blood pressure?

The exact causes of high blood pressure are not known in most cases. However, your chances of developing high blood pressure may be increased if you

Have a family history of high blood pressure

Have chronic kidney disease

Are overweight

Use a lot of table salt; eat a lot of packaged and fast foods

Use birth control pills

Have diabetes

Use illegal drugs

Drink large amounts of alcohol (beer, wine, or liquor)

How Can High Blood Pressure Hurt My Body?

Untreated high blood pressure can damage your heart, brain, eyes, and kidneys. This damage can lead to heart attacks, strokes, and kidney failure. If you also have diabetes, your chance of developing these other conditions is even greater. For this reason, it is important to keep your blood sugar under control and follow your healthcare provider’s advice carefully.

How Are High Blood Pressure And Kidney Disease Related?

Some types of kidney disease may cause high blood pressure. More often, it is high blood pressure that causes
kidney disease. In addition, high blood pressure speeds up the loss of kidney function in people with kidney disease. Because people with high blood pressure are at increased risk for developing chronic kidney disease, they should be tested for kidney disease.

These tests should include:

A test for protein in the Urine

Protein is an important building block that keeps your body strong and healthy. When your kidneys are working properly, they keep protein inside your body. However, when the kidneys are damaged, protein leaks into the urine.

A blood test for Creatinine

Which is a waste product from muscle activity. The results of this test can be used to estimate your glomerular  filtration rate (GFR), which tells your healthcare provider how well your kidneys are working.
