High Blood Urea: Causes, Symptoms, and Treatments

The urea It is a by-product derived by the human body when the liver is assimilating proteins and nitrogen compounds. It was discovered in 1932 by HA Krebs Y K. Henseleit, who noted that when ornithine or arginine was added, the liver began to produce a greater amount of ammonia.

Its place of origin is the liver and is the result of a cycle known as the “urea cycle”. This substance is usually expelled from the body through urine, but when urea levels get too high in the blood It can bring terrible consequences such as kidney failure, liver failure, nervous system disorders, heart failure problems, among others.

What causes high blood urea?

To determine the levels of urea present in the body, doctors go to blood tests to know the levels of urea and creatinine, which allows them to know in what condition the kidneys are and if they are draining properly. Some other reasons that can cause it to increase can be:

  • A diet with too much protein
  • Dehydration problems
  • Bleeding in the gastrointestinal system
  • Exercising too hard and regularly
