High Urea In Blood Test
High urea is a common symptom in patients with kidney disease, while patients may be curious about what they can know from their high urea. It is necessary for patients to have a better understanding about this aspect.
What is blood urea?
Urea is the metabolic waste of protein, and it is mainly excreted out by kidneys. While when urea is passing through kidney tubules, the kidney tubules will reabsorb the urea. But if the higher the urine flow rate is, the more urea will be excreted. In normal condition, the level of blood urea changes in a stable range, which is 3.2~7.1mmol/L.
Why patients have high blood urea?
When the value of urea in blood is higher than its normal range, we called it high blood urea.
In fact, high blood urea can be caused by many reasons. For example, if people have too much protein, they will have high urea. If people in the state of high catabolism, they may also have high urea in their blood. Besides, when people in the condition of severe dehydration, acute infection, bleeding in upper gastrointestinal tract, etc, people will also have high urea in their blood. In these conditions, the high level of urea will not stay long.
On the other hand, high urea can also be caused by kidney damage, and the level of urea in blood is also a common standard to judge patients’ kidney condition.
As we know, urea is the metabolic waste of protein, and it is mainly excreted out by kidneys. In fact, our kidneys have strong compensation, and as long as more than half kidney function is normal, there will not be any health problem caused by kidney disease. So when patients find they have continuously high urea in blood, it means patients already have severe kidney insufficiency. What’s more, it is worth mentioning that patients will not have obvious symptom until more than three fourths kidney function is damaged.
Thereby, if patients who have kidney disease find they have continuous high urea in blood test, they should take measures as soon as possible, and they should follow their doctor’s advice in their lifestyle and cooperate with their doctor’s arrangement in their treatment.
