The kidney has a major role in the maintenance of blood pressure. Kidney disease may affect the functions of the kidneys to the point that impairs this homeostasis (control), resulting in elevation of blood pressure. Vice-versa, high blood pressure / hypertension can lead to kidney failure. It is one of the leading causes of kidney failure in many countries. It occurs after prolonged periods of poorly controlled blood pressure.High blood pressure / Hypertension can lead to kidney failure or may worsen existing kidney diseases.
If blood pressure is uncontrolled, the progression to end-stage kidney failure is much earlier. High blood pressure / Hypertension also affects the cardiovascular system significantly and causes narrowing and thickening of the blood vessels. It also enlarges the heart and causes it to weaken in the chronic state. Essential hypertension is fairly common and may not present symptoms for a long time. Its cause is not defined but is certainly multifactorial.
