Urea nitrogen can be seen in physiological conditions such as high protein diet, which is generally not harmful to the body; other pathological conditions such as renal disease, gastrointestinal bleeding, hyperthyroidism, etc., when nausea, vomiting, breathlessness, hypertension, infection, hyperthyroidism heart disease, and so on, and even endangered life.
Urea nitrogen is the end product of protein metabolism in the body, and the glomerular filtration function can be judged clinically by this test. Elevated urea nitrogen can be seen in physiological conditions such as high protein diet, usually is not harmful, can be normalized by itself, no need to worry too much, pay attention to regular medical monitoring can be.
In addition to physiological factors, some people with high urea nitrogen need to be alerted to kidney diseases, such as glomerulonephritis, pyelonephritis, polycystic kidney, and so on. When renal disease, can lead to a decrease in glomerular filtration rate, resulting in increased urea nitrogen, which may be nausea, vomiting, swelling of the limbs, breathlessness, anemia, hypertension, etc., and may even lead to death.
Some patients with gastrointestinal bleeding and hyperthyroidism may also have high urea nitrogen, and hemorrhagic shock, infection, and hyperthyroidism may occur.
For high urea nitrogen, should be actively regular hospitals, with the doctor to further do other tests, in order to confirm the diagnosis of the disease after the treatment prescribed by the doctor, to reduce the harm caused to the organism.
