9Signs That Your Kidneys Aren’t Working Properly

9. High Blood Pressure

For your body to work just fine, your kidneys and circulatory system form a symbiotic relationship (9). This means when your kidneys are damaged, you can expect your blood pressure to shoot up. To explain this further, the kidneys are made up of nephrons, which are responsible for filtering away waste materials and excess fluid from your blood. However, when your blood vessels get damaged, your nephrons are unable to get adequate nutrients and oxygen, leading to a rise in blood pressure.
