High blood pressure can damage the kidneys, and kidney damage can increase blood pressure.

Your blood pressure and kidneys can affect each other. Because kidney disease can raise blood pressure, the greatest risk for people with kidney disease is not actually kidney failure, but rather developing it.heart diseaseoAVC. Watching your blood pressure helps keep your kidneys healthy.

What is kidney disease?

The term kidney disease describes a group of problems in which the kidneys do not work as well as they should. You may also hear it as chronic kidney disease (CKD). It is usually mild, has no symptoms, and can be treated by you and your doctor, but it rarely becomes more advanced, leading to kidney failure and other serious health problems.

What are the kidneys doing?
Your kidneys play an important role in removing waste from your body and controlling your blood pressure. They act as filters for the blood, filtering out excess water, waste, and toxins and removing them from the body with urine (urine). When your kidneys are not working properly, fluid and waste can build up in your body.

The kidneys help control blood pressure by removing water and salt from the blood and by producing hormones involved in blood pressure control.

The kidneys also produce other hormones involved in maintaining healthy red blood cells and bones, and kidney disease can lead to anemia and bone disease.

How does high blood pressure cause kidney disease?

Uncontrolled high blood pressure is addedtension in the blood vessels, and over time they can become narrower and stiffer. When the blood vessels to the kidneys are affected, not enough blood reaches the kidney cells, so they don't get enough oxygen and nutrients, leading to scarring of the kidney tissue. This means that the kidneys are less able to do their job.

As the kidneys sense that they need more blood and oxygen, they produce hormones that further increase blood pressure; this can become a vicious circle.

  • a blood test - to measure how much fluid your kidneys can filter in a minute - this is your GFR, or glomerular filtration rate. A low GFR means that your kidneys are not working properly.

If these tests show signs of kidney damage, you may have other tests to see where and how much damage is present. For example, an ultrasound to get a picture of your kidneys or a biopsy, which takes a small sample and looks at it under a microscope.

Chronic kidney disease (CKD) is divided into stages 1-5, with stage 5 being the most advanced. Stage 3 CKD is considered a moderate disease and this is where your doctor will want to monitor you more closely.
