What is the harm of urea high?

Urea generally refers to urea nitrogen, urea nitrogen elevation is generally caused by kidney disease. The harm of urea nitrogen elevation includes causing hyperkalemia, renal hypertension, metabolic acidosis and other diseases.

1, hyperkalemia

Kidney function decline can lead to urea nitrogen elevation, kidney function decline potassium excretion capacity will be affected to a certain extent, a large amount of potassium accumulation in the body to form hyperkalemia.

2, renal hypertension

due to kidney disease for a long time not cured caused by renal dysfunction, urea nitrogen in the blood will be significantly increased. Renal dysfunction may lead to kidney drainage, sodium excretion difficulties, easy to form water and sodium retention, thus causing hypertension, patients may appear renal hypertension.

3. metabolic acidosis Increased

urea nitrogen indicates that renal function may be impaired. When the function of renal acid excretion and alkali preservation decreases, it is difficult to discharge acidic substances in the body, which is easy to cause metabolic acidosis.

Patients with elevated urea nitrogen need to check renal function regularly, pay more attention to rest at ordinary times, and try to take a low-salt and low-protein diet as the main diet.
