The reason for high urea nitrogen content

The products of protein metabolism in the human body also include urea nitrogen. Generally speaking, when people go to the hospital to check their kidney function, they should also pay attention to various indicators in the body. Among them, blood urea nitrogen is also one of the main indicators for checking kidney function. When urea nitrogen is too high, it will also have an impact on people's health. The reasons for high urea nitrogen are also quite complicated, so you should pay attention to understand them.

1. Reasons

High renal level is seen in renal dysfunction caused by acute nephritis, chronic nephritis, toxic nephritis, severe pyelonephritis, renal tuberculosis, renal vascular sclerosis, congenital polycystic kidney and renal tumors. Prerenal elevation is seen in congestive heart failure, severe burns, shock, massive gastrointestinal bleeding, dehydration, severe infection, diabetic acidosis, adrenal cortex insufficiency, hepatorenal syndrome, etc. Postrenal hyperplasia is seen when urinary tract obstruction increases renal tissue pressure. Therefore, in order to clarify the cause of the disease, it is best to consult a doctor before deciding on treatment.

2. Symptoms

Postrenal hypertension occurs when urinary tract obstruction increases renal tissue pressure, thereby reducing glomerular filtration pressure, such as prostate hypertrophy, urethral obstruction caused by tumor compression, or bilateral ureteral stones. A simple increase in urea nitrogen can be caused by consuming too much protein in the diet. By changing the dietary structure and balancing the combination of protein, sugary foods and vegetables, the level can quickly return to normal.

3. Note

Reduce the total calories of food. Eat in moderation to prevent obesity, pay attention to your diet and eat some fresh vegetables and fruits to supplement high-quality protein. Limit purine intake and eat less animal offal, seafood, meat, lentils, peanuts, spinach, etc. Properly control protein supplementation. One cup of milk, one egg and two taels of lean meat every day can basically meet the body's needs for protein. Fat can inhibit the excretion of uric acid, so it should be eaten less, especially animal fat.
