Kidney Disease Induced by High Blood Pressure

Pathophysiology

Structure of the Kidneys

The kidneys are two bean-shaped organs located on either side of the spine. They contain tiny structures called nephrons? that filter blood. Each kidney has about a million nephrons.

Blood Supply

Blood enters the kidneys through the renal? arteries? and exits through the renal veins?. The blood vessels within the kidneys help regulate blood pressure and filter waste.

Nerve Supply

The kidneys receive nerve signals that help control blood flow and filtration. These nerves play a role in regulating blood pressure and kidney function.

Types of Kidney Disease Induced by High Blood Pressure

1. Chronic Kidney Disease? (CKD?): Gradual loss of kidney function over time.
2. Acute Kidney Injury? (AKI?): Sudden and often reversible loss of kidney function.
3. Hypertensive Nephrosclerosis: Hardening of the small blood vessels in the kidneys due to high blood pressure.
4. Diabetic Nephropathy: Kidney damage caused by diabetes?, often linked with hypertension.
5. Renal Artery? Stenosis?: Narrowing of the arteries that supply blood to the kidneys, often due to high blood pressure.
