Urea nitrogen is too high, what to do, what is the matter with high urea nitrogen

In the early stages of renal impairment, blood urea nitrogen can be in the normal range. When the glomerular filtration rate drops below 50% of normal, the concentration of blood urea nitrogen rises rapidly Diet: 1

Renal insufficiency decompensated CCR 20-50 ml minThe protein should be controlled at 45-50g, and the protein should be of high quality. Vegetable protein should be eaten as little as possible, because it contains more non-essential amino acids, and it is best to remove the vegetable protein contained in rice and noodles.

To use foods that contain high-quality protein, such as lean meats, fish, eggs, etc. 2.Guaranteed co-supply of heat to the thermal components to reduce the depletion of the body's protein pool.

It is advisable to have 30kca kg of body weight per day, mainly supplied by carbohydrates and fats. Patients with poor diet can be given the preface Chinese medicine Erchen decoction (Banxia, Poria cocos, tangerine peel, licorice) and add anti-conduction drugs such as grain buds and Shenqu. Foods should be given foods rich in B vitamins and vitamin C.

The general hospital for urea nitrogen test method is a two-point quantitative method, the normal range is 4-10, according to your situation, it can be considered that the concentration of body liquid nitrogen is too large, drink more water to promote nitrogen excretion, no special **.

The detection of urea nitrogen is greatly affected by diet and physiological state, you have no problem in this situation, just drink more water, sometimes excessive exercise, eating more meat products before the test will also be like this, don't worry.

If you have a light diet and look at it again and again, the impact of diet on urea nitrogen is relatively large.

It may also be a test error, and the test report indicators that may be diseases need to be rechecked with caution, and they need to be checked again every once in a while, and the cost of blood test is not high. Or go to a better first-level hospital for a follow-up. It doesn't hurt to be careful.

But the urinary nitrogen is high and has no clinical significance! May be related to a high-protein diet! In the future, the re-examination is estimated to come down!

A full re-examination of renal function and a B-ultrasound examination of the kidneys.

Daily life with high urea nitrogen should pay attention to diet, and the specific precautions are as follows:

1. Limit the intake of purines and eat less offal, seafood, meat, lentils, peanuts, spinach, etc.

2. Reduce the total calories of food. Eat in moderation to prevent overweight.

3. Carbohydrates can promote the excretion of uric acid, so we should eat more rice, flour and cereals.

4. Maintain adequate vitamin B and vitamin C, eat more green leafy vegetables, and eat more oranges and apples.

5. Protein intake should be limited. A glass of milk, an egg and two pairs of clenbuterol can basically meet the body's protein needs.

6. Fat can inhibit the excretion of uric acid, so you should eat less, especially animal fat.

7. Drink more water 2000 to 3000 ml a day to increase urine output and promote uric acid excretion.

8. Do not use drugs that inhibit uric acid excretion, such as some antihypertensive drugs.

High urea krypton often means that there is a problem with our kidneys, and various renal parenchymal lesions will lead to elevation, such as the commonly used glomerulitis, membranous nephritis, renal insufficiency, acute and chronic renal failure, and intrarenal space-occupying lesions can increase urea nitrogen.

All kinds of renal parenchymal lesions can cause high urea nitrogen, and it is necessary to go to a regular hospital to find out the cause and symptoms**.

Eat more vegetables and fruits, and keep your mouth shut. Eat only seven minutes full. The body will definitely return to its normal state.

Daily life with high urea nitrogen should pay attention to diet, and the specific precautions are as follows:

1. Limit purine intake, eat less animal offal, seafood, meat, lentils, peanuts, spinach, etc.;

2. Reduce the total calories of food. Moderate your diet to prevent obesity;

3. Carbohydrates can promote the excretion of uric acid, so it is advisable to eat more rice, noodles and cereals;

4. Maintain sufficient vitamin B and vitamin C, eat more green leafy vegetables, citrus and apples;

5. Limit protein intake appropriately. 1 cup of milk, 1 egg, and 2 taels of lean meat a day can basically meet the body's protein needs;

6. Fat can inhibit the excretion of uric acid, so you should eat less, especially animal fat;

7. Drink a large amount of water 2000-3000 ml every day to increase urine output and promote uric acid discharge;

8. It is not advisable to use drugs that inhibit the excretion of uric acid, such as some antihypertensive drugs, diuretics, salicylic acid and other drugs; If you have a meal with family or friends, eat more meat and seafood, and take sodium bicarbonate in time after returning home, you can prevent or reduce the attack;

9. Avoid predisposing factors such as overwork, tension, cold, dampness and joint damage;

10. Eat more alkaline foods, such as cabbage, radish, carrots, potatoes, bananas, apples, melons, soda crackers, etc., and take sodium bicarbonate if necessary to alkalize urine and prevent urinary tract stones; Eat more whole grains and potatoes on the diet: eat more red foods, the well-known foods such as wolfberry, cherry, strawberry, pomegranate pumpkin, carrot and other foods have good antioxidant properties, all of which are beneficial to cardiovascular food, and eat them for a long time;

11. Avoid alcohol, especially beer, because alcohol is easy to accumulate lactic acid in the body and induce gout.

High urea nitrogen levels indicate that there is a problem with the kidneys in the body, and you need to go to the hospital for further examination.

1) Renal hypersensitivity 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. In particular, it has special value for the diagnosis of uremia, and its increase is directly proportional to the severity of the disease, such as more than 9 mmol L in the azotemia stage, and more than 20 mmol L in the uremia stage, which is helpful for the estimation of the disease.

2) Prerenal hypersensitivity is seen in congestive heart failure, severe burns, shock, gastrointestinal hemorrhage, dehydration, severe infection, diabetic acidosis, adrenal insufficiency, hepatorenal syndrome, etc.

3) Postrenal hypersensitivity is seen when the pressure of renal tissue is increased due to urinary tract obstruction, which reduces the glomerular filtration pressure, such as prostatic hypertrophy, urethral obstruction caused by tumor compression, or ureteral stones on both sides. pa。。wa

If you don't have kidney disease, you will have a high level of protein (meat) if you eat a lot of it.

Urea nitrogen is a metabolite of proteins and amino acids broken down by the body, a process that is carried out by the liver and then excreted by the kidneys. Elevated urea nitrogen can be seen in excessive intake of protein or amino acids, or abnormal liver function, but it is often associated with elevated liver enzymes.

In addition, it can be seen in renal insufficiency, which is caused by the decrease in the excretion of urea nitrogen by the kidneys. Therefore, it is necessary to check the blood routine, biochemistry and urine routine to conduct a preliminary screening for some of the above possibilities, and then go to the gastroenterology and nephrology departments for further consultation according to the results.

Urea nitrogen and blood creatinine are the two most important indicators of kidney function, and the high and low values of urea nitrogen reflect the good or bad kidney function. A higher than normal urea nitrogen value indicates that the urea nitrogen is high.

Acute and chronic nephritis, pyelonephritis, gout and other diseases, these diseases will cause high urea nitrogen, in addition, if you eat too much protein for a while, blood urea nitrogen will also be high, so you must combine a comprehensive analysis of clinical symptoms, the normal value of fasting blood sugar is <6, you are also higher than the normal value, whether there are diabetes symptoms such as polydipsia, polyuria, and weight loss, so please recheck again, and do a two-hour postprandial blood glucose or glucose tolerance test to rule out diabetes.

To see what causes it, you can recheck your kidney function with a vegetarian diet for 3 days or a week, and you need to find out the cause and syndrome**.
