Early in the morning, the red-faced man in the community knocked on my door [doctor, last time you told me about my mother’s chronic renal insufficiency. Today I took her to the outpatient clinic for reexamination, and the doctor said my mother had renal anemia. How can this anemia still be related to the kidney? Do you need me to give her a blood transfusion? ] The man’s face of doubt.
I asked the couple to sit down and gave them the following answers.
Nephropathy can cause anemia?
Chronic renal insufficiency caused by various reasons can all cause anemia, Moreover, the degree of anemia will worsen with the deterioration of renal function. There are also certain individual differences, that is, patients with the same renal function level may have different degrees of anemia. At the same time, compared with patients without diabetes, patients with chronic renal insufficiency with diabetes are more prone to anemia and the degree of anemia is heavier.
Auntie now creatinine 430 umol/L, is about in chronic kidney disease 3 ~ 4 stage, the proportion of patients with anemia gradually increases, anemia degree aggravates. If it develops to uremia stage, anemia is a very common phenomenon.
Why is the kidney broken and anemic?
Most people’s understanding of the kidney is limited to [sewage treatment plants]. They think that the kidney is only an organ that excretes human water and toxins, which greatly underestimates the strength of the kidney. [Renal anemia] [Renal hypertension] [Renal osteopathy], these are common diseases caused by renal function damage. From the names of these diseases, the damage to the body after renal function damage can be seen.
So what about renal anemia in what?
First of all, clarify several concepts. Bone marrow is the hematopoietic center of human body. The amount of hemoglobin (also known as hemoglobin) in red blood cells is a common indicator to judge whether anemia is common. Under normal circumstances, The life span of red blood cells in the human body is 120 days, that is, the whole body will lose 1/120 red blood cells every day. Like the national population, the birth rate and death rate maintain a dynamic balance. In the human body, while red blood cells are aging and dying, bone marrow is also constantly producing new red blood cells, making the human body full of fresh blood at any time.
EPO (erythropoietin) secreted by kidney can stimulate bone marrow hematopoiesis. If renal function is damaged, EPO decreases accordingly, bone marrow cannot be fully stimulated, and enough red blood cells cannot be produced, which is the main cause of renal anemia.
The content of various toxins in patients with chronic renal insufficiency increases. Some toxins can damage red blood cells, shorten the life span of red blood cells, and make the newborn rate of red blood cells [unable to catch up with] the death rate of red blood cells, thus causing anemia.
The consumption of iron, folic acid and VitB12 in patients with chronic renal insufficiency is huge, and these three are the three indispensable raw materials for bone marrow hematopoiesis. If not fully supplied with hematopoietic raw materials, anemia can also be caused.
In addition, anemia can be caused by acid-base imbalance, electrolyte disorder, chronic blood loss, dialysis-related hemolysis and other reasons in patients with chronic renal insufficiency.
This anemia caused by renal function damage is called renal anemia.
Doctor, I can’t understand so much you say, just tell me how to do it. Listen to the street pharmacy that there are secret recipes for ancestral herbs to tonify kidney and produce blood. Do you think I should do some?
Kidney sex anemia how to do?
Don’t take medicine indiscriminately, don’t take medicine indiscriminately, don’t take medicine indiscriminately. Say important things three times.
I have seen too many patients with kidney function deterioration and anemia caused by eating [traditional Chinese medicine] and [folk prescription] indiscriminately. Please be sure to go to a regular hospital for regular medical treatment.
It is recommended that patients with renal anemia:
- Supplement EPO (erythropoietin) and hematopoietic raw materials (iron, folic acid, VitB12) according to doctor’s advice; Patients who reach the dialysis index shall undergo full dialysis to reduce the toxin level in the body; At the same time, cooperate with doctors to correct internal environmental disorders in the body and avoid other complications and complications. The internal environmental disorders of chronic kidney disease are mainly electrolyte disorders and acid-base imbalance.
Auntie now has a hemoglobin of 75 g/l, so there is no need for blood transfusion for the time being. Besides, blood transfusion is only a temporary emergency treatment plan. Anemia caused by this chronic disease requires long-term medical intervention.
Pay attention to what in your diet?
Because renal anemia is closely related to renal function, renal anemia is well controlled if the progress of renal diseases is well controlled. Therefore, renal anemia patients should follow the dietary principles of chronic renal insufficiency patients, i.e. Low quality protein, low salt and low fat diet.
The closer the amino acid pattern of protein in food is to that of human protein, the easier it is to be absorbed, which is called high-quality protein. For example, egg, milk, fish and soybean protein are common animal proteins.
Low quality protein: According to the degree of renal damage, patients with chronic renal insufficiency are recommended to control the intake of low quality protein by 0.6 ~ 1.0 g/day per kilogram of body weight (for example, for those with a body weight of 50 kg, the daily intake of protein is 30 ~ 50 g) and supplement a-ketoacid. This low quality protein diet can delay the progression of chronic renal diseases and ensure good nutritional status.
Low salt: salt contains a large amount of sodium. The excretion of urine sodium in patients with chronic kidney diseases is weakened. If water and sodium are not restricted, water and sodium accumulation in the body will inevitably occur, blood pressure will increase, internal environment will be disordered, and disease progression will be accelerated. Many clinical studies have shown that sodium-limited diet can reduce blood pressure, reduce urine protein and delay the progress of kidney diseases.
It is suggested that patients with chronic kidney diseases avoid eating processed foods with high sodium content (pickled products, canned food, etc.), try to eat natural and non/less processed foods, and carefully use seasoning products such as soy sauce, vinegar, monosodium glutamate, chili sauce, broad bean paste, etc. to control the daily salt intake below 6 g (3 g salt = half lid after removing rubber pad or 15 ml soy sauce).
Low-fat: In addition to a low-fat diet, more emphasis is placed on the type of fatty acid intake. The proportion of polyunsaturated fatty acids should be appropriately increased and the proportion of trans fatty acids and saturated fatty acids should be reduced.
For patients with chronic kidney diseases, due to the need to control the intake of protein and fat, their food supplies more carbohydrates mainly from plants (grains, vegetables and fruits).
[Sounds reasonable, but it’s abstract, I still don’t understand] The red-faced man’s face is even redder.
In short, aunts should try their best to return to their original nature in diet and play less tricks.
- One egg, one cup of milk, a little vegetables and 1 ~ 2 ounces of lean meat every day; Less seasoning in the meal; Try to simplify the food processing process and use less or no frying or frying methods. Replacing animal oil with vegetable oil; Eat less cakes, snacks, etc.
