Kidney Failure Patients Appear High Blood Pressure During Dialysis

Some kidney failure patients always appear the high blood pressure during the dialysis. Is it a normal phenomenon? And why they can appear the high blood pressure?

Elevated blood pressure (BP), also known as hypertension, is common in modern day society. Approximately 30 percent of adult Americans are believed to have hypertension when defined as a blood pressure greater than 140 (systolic – the top number is the pressure when the heart pumps blood out) over 90 (diastolic – the bottom number is the pressure when the heart relaxes before the next beat). This definition of hypertension reading greater than 140/90 is based on two or more doctor’s office blood pressure measurements after an initial screening while a patient is off blood pressure medicine.

Defining when rising blood pressure becomes hypertension is important, because having this condition raises the risk of serious complications, such as strokes, heart attacks and premature death. Reducing blood pressure in patients with hypertension reduces the risks of such events.

High blood pressure is even more common in persons with chronic kidney disease (CKD), and can affect as many as 80 percent of patients. The reasons for this are complicated, and may depend on the underlying causes of the kidney disease. Activation of certain hormonal systems and parts of the central nervous system play a role in this. The retention of salt and fluids by the kidneys also is an important factor, and treatment is often directed at eliminating this excess salt and water through the use of diuretics, a medicine prescribed by a doctor. There are a variety of other medication categories used to lower blood pressure in kidney patients, since people with kidney disease seem to be at even higher risk of complications if high blood pressure is not properly treated.

Not only does kidney disease cause high blood pressure; high blood pressure can also cause or worsen kidney disease. This may be especially true in patients with diabetes and other specific disorders. Having high blood pressure can cause gradual injury to parts of the kidney that filter the blood, such as the glomeruli.
