ALL YOU NEED TO KNOW ABOUT HYPERTENSION & CHRONIC KIDNEY DISEASES

Hypertension, better known as high blood pressure, has been called a silent killer because most people don’t recognize they have it, since there are generally no symptoms or warning signs.  Blood pressure is a measure of how hard the blood pushes against the walls of your arteries as it moves through your body. Any factor that increases pressure against the artery walls can lead to elevated blood pressure. The build-up of fatty deposits in your arteries (atherosclerosis) can lead to high blood pressure. When blood pressure is high, it starts to damage the blood vessels, heart and kidneys, which can lead to stroke, heart attack and kidney failure. It’s estimated that 1 in 3 adults has high blood pressure. And most of the time, the cause is unknown and often referred to as essential hypertension or primary hypertension.

CORRELATION OF HIGH BLOOD PRESSURE AND KIDNEY DISEASE

  1. High blood pressure is one of the leading causes of CKD. Over time, high blood pressure can damage blood vessels throughout your body. This can reduce the blood supply to important organs like kidneys. It damages the tiny filtering units in your kidneys. As a result, the kidneys may stop removing wastes and extra fluid from your blood. The extra fluid in your blood vessels may build up and raise blood pressure even more.
  2. High blood pressure can also be a complication of CKD. Kidneys play an important role in keeping your blood pressure in a healthy range. Diseased kidneys are less likely to help regulate your blood pressure; Hence, it can implicitly lead to Hypertension.

KIDNEY DISEASES WHICH CAN CAUSE HYPERTENSION

  • Diabetic Kidney Disease
  • Polycystic Kidney Disease
  • Glomerular Disease
  • Renovascular Hypertension
  • Renal Calculus Disease

Chronic kidney disease (CKD) is both a common cause of hypertension and CKD is also a complication of uncontrolled hypertension. Any person diagnosed with hypertension need to be evaluated for kidney disease with complete urine exam and serum creatinine to asses kidney function (GFR).

It is important to screen for hypertension in all adults and recognise the cause of hypertension and treat them as it significantly reduces complications. Blood pressure is usually checked by using a blood pressure cuff around your arm. It should be checked every time you visit your doctor or clinic. You may also be taught to check your own blood pressure at home. In addition to home BP monitoring, it is advisable to check 24-Hour Ambulatory BP monitoring (ABPM) which allows better assessment of the diurnal variation in BP. Controlling hypertension in those with chronic kidney disease (CKD) not only slows progression of renal damage but reduces the risk of cardiovascular disease. Blood Pressure (BP) control in CKD can be achieved with a combination of antihypertensive medications as well as lifestyle modifications such as dietary salt restriction and weight loss.
