Creatinine 459 urea nitrogen 20, what can you eat high?

The dietary attention of patients with high urea nitrogen includes: eating more alkaline food, drinking plenty of water, avoiding alcohol and other problems. Alkaline foods include:

cabbage, radish, carrots, potatoes, bananas, apples, melons, soda crackers, etc., sodium bicarbonate can be taken if necessary to alkalize urine and prevent urinary tract stones;

Avoid alcohol, especially beer, because alcohol tends to accumulate lactic acid in the body and induce gout;

Avoid triggers such as overwork, stress, cold, dampness and joint damage;

Drink a large amount of water 2000-3000 ml a day to increase urine output and promote uric acid excretion; Drugs that inhibit uric acid excretion should not be used, 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. High urea nitrogen nephrogenic disease is seen in renal dysfunction caused by acute nephritis, chronic nephritis, toxic nephritis, severe pyelonephritis, renal tuberculosis, renal vascular sclerosis, congenital polycystic kidney disease, and renal tumors.

Urea nitrogen is one of the main biochemical tests that reflect the status of renal function. However, renal insufficiency is not diagnosed in all patients with elevated blood urea nitrogen. Urea nitrogen is a product of protein metabolism in the body, when the human body ingests a large amount of protein, it can produce more urea nitrogen after metabolism, and there is a transient increase in urea nitrogen.

By dilating blood vessels, miniaturized Chinese medicine infiltrates **, improves renal microcirculation, reduces glomerular pressure, promotes glomerular repair, changes in the structure of damaged diseased tissues, and restores function, and excretes urea nitrogen.

For patients with high creatinine, the diet requires low salt, moderate amount of high-quality protein, low fat, low potassium, and also needs to reduce the intake of phosphorus-containing foods and high-purine foods.

Creatinine reflects the function of glomerular filtration in the body. Under normal circumstances, the human body will metabolize and produce creatinine, which is excreted from the body through the kidneys, so normal human creatinine can be maintained at a relatively low level. If there is a problem with the kidneys, creatinine cannot be excreted through the kidneys, and creatinine accumulates in the blood, and an elevated creatinine often indicates that the patient may have renal insufficiency.

For patients with high creatinine, the daily salt intake should be controlled within 3g, and the consumption of monosodium glutamate, soy sauce, pickles, etc. should be reduced or prohibited, and pickled products should not be eaten; Protein intake should be controlled per kilogram of body weight, mainly animal protein, such as eggs, milk, lean meat, etc., and plant protein intake, such as beans and soy products, should also be reduced; Try to choose vegetable oils for cooking, such as corn oil, canola oil, olive oil, etc.; At the same time, the body's potassium excretion will be hindered after renal insufficiency, so it is necessary to have a low-potassium diet and do not eat foods with high potassium content such as bananas, seaweed, leeks, etc.; It is also necessary to reduce the intake of phosphorus-containing foods as much as possible, such as purple rice, sorghum, black rice, etc., as foods with high phosphorus content may increase the risk of hyperphosphatemia; High creatinine may also be complicated by hyperuricemia, so it is necessary to abstain from high-purine foods such as pig liver, pig lungs, and oysters.

Hello creatinine and urea nitrogen are commonly used indicators to measure kidney function, so higher than normal will naturally think about whether there is a problem with the kidneys. In fact, for laboratory results must be combined with comprehensive clinical analysis, the following recommendations are recommended;

1. First of all, rule out whether you have any manifestations and history of kidney disease? Such as edema, high blood pressure, proteinuria, etc. Because creatinine and other kidney function indicators do not appear until the kidneys have been damaged by more than 50%.

The easiest way is to check the urine and do a kidney ultrasound, if it is all normal, and there is no history of kidney disease in the past, it means that the kidney is not diseased, if the kidney is not diseased, the kidney is not damaged, and the kidney function must be normal.

2. If there is no kidney disease, why are creatinine and urea nitrogen higher than normal? This requires some understanding of the principle.

Creatinine is a metabolite of creatine in the human body, and the amount of creatine is directly proportional to the amount of muscle, so the creatinine value of adult men is higher than that of women, and the creatinine value is lower when there is less muscle in old age. In general, the normal value refers to the average value examined by many normal people, and there is also the concept of standard deviation in statistics, that is, the mean represents 95% confidence, and the standard deviation is added to reach 100%, that is, 5% of people are above or below the mean, and it is still normal. Therefore, you may have high indicators, but it is not necessarily due to kidney disease.

The conjecture and interpretation according to the above principle is; You may belong to the tall, muscular male. For a more accurate judgment, creatinine clearance can be done.

Blood urea nitrogen is the end product of human protein metabolism, and its production depends on the intake of protein in the diet, tissue protein catabolism and liver function.

3. It should be pointed out that some drugs (including Chinese and Western medicines) can affect kidney function, it is worth noting and please check if there are any suspicious drugs.

In short, a single indicator is high, not necessarily caused by a certain disease, do not need to be nervous, do more understanding and analysis and regular review before drawing conclusions, it is beneficial to health.

Analysis: Serum creatinine and urea nitrogen are nitrogen-containing metabolic wastes in the body. It is mainly metabolized by the kidneys and excreted from the body.

It should be a problem with kidney disease. High urea nitrogen: indicates that kidney function is declining; Creatinine high:

It means that the kidneys are damaged, so be careful of kidney failure, but there is no need to worry about uremia.

Guidance: It is recommended to recheck renal function and do renal puncture if necessary to determine the pathological type. Take a break for a while and recheck. If it is high, go to the hospital for further examination, and if it recovers, you can follow up.

First of all, change your eating habits, eat light and low protein, try to eat less meat, many people say I often exercise, why do I still get sick, in fact, animal protein can cause a lot of diseases people often ignore, eat more vitamin-rich foods to improve resistance, in addition you have to rest more, if the kidneys are not good, exercise gently, more go out to breathe is good, you say you don't drink water, in fact, drinking water is very good for detoxification, drink more water, but pay attention to whether people have edema, edema don't drink more water, The creatinine standard in our hospital (Second Military University) is 55-110, you don't care too much, it's not good for your health, you can find a good Chinese medicine for conditioning, remember to be a good Chinese medicine, Chinese medicine who doesn't know how to treat diseases can only increase the burden, Chinese medicine cheats money a lot, and eating more grapes and dark foods (Bolin and the like) is good for the kidneys, black into the kidneys, that's all I think of, relax, I wish you health.

Most people know that high creatinine uric acid means that there is a problem with the kidneys, so do you know what is the cause of low creatinine? What is low blood creatinine? Urea nitrogen and creatinine below normal values on renal function tests are generally not clinically significant.

There are many causes of low creatinine and can be related to diseases such as anemia, muscular dystrophy, amyotrophy, leukemia, diabetes insipidus, etc. If the creatinine measurement is slightly lower than the normal creatinine value, it can be retested.

For example, urea nitrogen and creatinine values are elevated, and urea nitrogen.

A low creatinine ratio, which is the cause of low creatinine, suggests the possibility of parenchymal renal damage.

Ratio of urea nitrogen creatinine, normal. 00

Its significance is mainly when an increase in urea nitrogen or creatinine is found to be a judgment that distinguishes between renal or prerenal (extrarenal) causes. If urea nitrogen.

A creatinine ratio of less than 20 is associated with a higher chance of renal disease, such as urea nitrogen.

A creatinine ratio greater than 20 is associated with a higher risk of prerenal causes.

There are many reasons for low creatinine, the value of urea nitrogen is easily affected by many other factors, so it cannot simply reflect kidney function, after clarifying what is going on with low blood creatinine, we also know that the value of creatinine in the absence of muscle disease, it is relatively simple, and can rise and fall synchronously with kidney function. So when the kidneys themselves have lesions, urea nitrogen and creatinine rise synchronously, so urea nitrogen.

The creatinine ratio falls within a certain range (less than 20). If it is a prerenal factor, often urea nitrogen will rise more, so urea nitrogen.

The creatinine value will be higher (greater than 20).

The above is a detailed description of what is going on with low blood creatinine, experts said that low creatinine is not a big deal, first of all, we must clarify the cause of low creatinine, the main may be malnutrition, if creatinine is high, it should be taken in time, so as not to harm the kidneys and develop uremia.

Creatinine: Creatinine is a product of muscle metabolism that is normally excreted in the urine. High creatinine is the damage to the inherent cells of the kidney, the metabolic function of the kidney is abnormal, and the toxins such as creatinine cannot be filtered normally, so that they accumulate in the body, and the increase in blood creatinine is the external manifestation of the decline in kidney function, if the blood creatinine level continues to rise, it will develop to end-stage uremia, which is life-threatening.

How to lower blood creatinine? The key to lowering blood creatinine is to repair the damaged kidney inherents according to the cause of blood creatinine.

Urea nitrogen: Urea nitrogen is a type of nitrogenous compound other than plasma protein nitrogen. Under normal circumstances, urea nitrogen in the blood is mainly excreted in the urine through glomerular filtration. When glomerular filtration fails, the concentration of urea nitrogen in the blood increases.

Therefore, measurement of blood urea nitrogen content can provide a rough estimate of glomerular filtration function. Blood urea nitrogen is mainly derived from the protein of food.

Hello WYQ 356, your question is as follows:

1. This is a manifestation of mild kidney damage in diabetes, which belongs to the early stage of diabetic nephropathy;

2. The key is to control blood sugar and prevent further aggravation of kidney damage; In addition, drugs that remove creatinine and urea nitrogen can be used, such as Kaitong, activated carbon (Acete), etc.

3. The tests that need to be done include kidney ultrasound, blood glucose, urinalysis, etc.

4. Usually pay attention not to use drugs that damage the kidneys (see drug description), do not exercise too much, eat a low-sugar and low-fat diet, and eat less animal offal.

Hope you are satisfied!

If there is a sudden and large increase in blood urea nitrogen levels, there must be some kind of trigger.

1) Consume too much protein. Proteins are metabolically broken down in the body to produce large amounts of urea nitrogen.

2) Sudden and noticeable fluctuations in blood pressure.

3) Infection. Both viral and bacterial infections can accelerate the deterioration of kidney function. At the same time, due to infection and fever, the breakdown of body proteins increases, resulting in an increase in blood urea nitrogen.

4) Dry stools. As part of the urea nitrogen in the body is excreted through the stool.

Both of these are indicators of kidney function tests, and if they are exceeded, they usually indicate renal insufficiency.

Due to the strong compensatory nature of the kidneys, mild kidney damage generally does not cause an increase in these two values, and only when the kidney damage is more severe, such as when the glomerular filtration rate drops below 50, it will cause an increase in the two values.

So, your question should be: Is it OK to drink more water for chronic kidney failure?

The answer is: no.

Because the kidney function is already seriously impaired at this time, drinking more water will increase the burden on the kidneys, especially for patients with reduced urine output, they should pay more attention to the amount of water they drink, usually 100-200 ml less than the 24-hour urine output.
