Causes of nephritis
The cause of nephritis is some blood tumors or colorectal cancer or lung cancer. All may cause nephritis. These tumors may express specific antigens or secrete certain factors, causing the body to produce antibodies and form immune complexes deposited in the renal glomerulus.
1. Caused by drugs: Some autoimmune diseases rarely manifest themselves as nephritis, such as rheumatoid arthritis. However, the use of some drugs, such as non-steroidal analgesics, anti-inflammatory drugs or gold-containing drugs, may cause glomerular inflammation. Nephritis. As for nephritis caused by vasculitis, the condition is usually serious and requires active treatment.
2. Invasion of moisture is the cause of nephritis: the spleen controls transportation and transformation, and likes dryness and hates dampness. For example, if you live in a wetland for a long time or wade in the rain, the water-dampness will invade internally, or you may not drink or eat properly, have too much raw and cold food, and the dampness will accumulate in the spleen. The wetness cannot go down and spreads to the skin, causing edema. Or dampness and heat turn into heat, and dampness and heat stagnate in the triple burner, causing the bladder to lose its ability to transmit and transform, and may also cause edema.
3. Feel the wind evil: The lungs are the qi of the whole body. They are connected with the fur on the outside. They are also the source of water. They regulate the water channels and pass down to the bladder. When wind evil attacks externally and lodges in the lung defense, the lungs fail to circulate and descend, the circulation fails, the wind restrains the water and the water cannot flow down to the bladder, which is caused by the conflict between Feng and Shui. It overflows the skin and causes edema, which is Feng Shui.
4. Internal invasion of sores is also the cause of nephritis: when the skin suffers from sores, boils, and carbuncles, evil poisons attack internally and return to the spleen and lungs. They contain the muscle surface externally and block water channels internally. Water vapor and evil poisons travel together. Internally, it spreads to the skin, causing edema.
Nephritis patients must not touch these 7 foods
1. High-salt diet
The edema in chronic nephritis is closely related to blood volume and sodium salt , so salt must be restricted and a low-salt diet must be given. Daily salt intake should be controlled below 2-4 grams to prevent aggravation of edema and increase in blood volume and accidents.
2. High-fat foods
Nephritis patients generally have symptoms of high blood pressure and anemia. If there is a large amount of animal fat, it will be very harmful to high blood pressure and anemia. The main reason is that animal fat can aggravate arteriosclerosis and inhibit hematopoietic function, so patients with nephritis must eat it with caution.
However, if there is no fat intake for nephritis, the body will become weaker, so vegetable oil can be used instead in daily life, about 60 grams per day.
3. Foods high in purine and nitrogen
In order to reduce the burden on the kidneys, foods that stimulate kidney cells should be limited, such as spinach, celery, radishes, beans, Soy products, sardines and chicken soup, fish soup, broth, etc. Because those foods are high in purine and nitrogen, when kidney function is poor, their metabolites cannot be excreted in time, which will have a negative impact on kidney function.
4. Strong condiments
Strong condiments are harmful to kidney function and should be avoided. Because MSG will make you thirsty after eating too much, you should use less MSG when limiting the amount of water you drink.
5. Foods with high potassium ions
Patients with nephritis and high creatinine must not eat foods with potassium ions, such as mushrooms, amaranth, cauliflower, Spinach, water spinach, bamboo shoots, tomatoes, carrots, pumpkins, mustard greens, pomegranates, loquats, peaches, willow dices, hard persimmons, oranges, sugar apples, etc. These all contain potassium ions. Also, do not eat raw vegetables. .
Others such as coffee, strong tea, chicken essence, beef essence, ginseng essence, thick broth, thin salt soy sauce, unsalted soy sauce, half salt, salt substitute, etc. also have high potassium content. When cooking, blanch food in boiling water first, remove the soup, and then fry in oil to reduce potassium intake.
6. Plant protein
Protein intake should depend on kidney function. When the patient has oliguria, edema, hypertension and nitrogen retention, it can reduce the burden on the kidneys and avoid the accumulation of non-protein nitrogen in the body. In particular, plant proteins contain a large amount of alkaloids, which can aggravate the intermediate metabolism of the kidneys, so beans and soy products should not be used as nutritional supplements.
7. Limit the amount of fluids
Patients with nephritis, high blood pressure and edema should limit their fluid intake. The daily intake should be controlled at 1200-1500 ml, including 800 ml of water content in drinks and dishes. If the edema is severe, the amount of water intake must be strictly controlled. In the case of urination, it can be relaxed appropriately.
Four early symptoms of pediatric nephritis
One of the early symptoms of chronic nephritis in children: eyelid edema
The main causes of eyelid edema in the early stages of chronic nephritis in children are: The kidney's water excretion and regulation functions are damaged, causing the water and sodium in the child's body to increase. Excessive water accumulates in loose tissue in the body, and the eyelids are the parts with more loose tissue. The characteristic of eyelid puffiness is obvious when getting up in the morning and subsides after activity.
The second early symptom of chronic nephritis in children: hematuria
Hematuria can be divided into gross hematuria and microscopic hematuria. Gross hematuria is hematuria that can be seen with the naked eye. The color of the urine is like meat washing water, turbid and red. Some children have blood streaks or blood clots in their urine. Microscopic hematuria can only be discovered under a microscope. The number of red blood cells per high-power field is greater than 1. Hematuria is the most common symptom in most children with chronic nephritis. Of course, there are many causes of hematuria, and nephritis is just one of them.
The third early symptom of chronic nephritis in children: Increased foam in urine
Urine foam increases, mainly smaller foams, which are interconnected and cannot be dispersed for a long time. It is suggested that there is protein in the urine of the child, which is caused by high tension. Of course, this symptom is inaccurate. If you do not have certain medical knowledge, it will often be ignored by parents or children. The simplest way is to go to the hospital to check your urine to rule out the possibility of proteinuria. Because the earliest change in chronic nephritis is urine.
The fourth early symptom of pediatric nephritis: Patients with moderate or above chronic renal insufficiency often suffer from anemia
Symptoms such as fatigue, dizziness, and pale complexion may occur. Patients with anemia should pay attention to the presence of chronic renal insufficiency if hematological diseases are excluded.
Dietary precautions for children with nephritis
1. A low-protein and low-phosphorus diet
A low-protein and low-phosphorus diet can reduce intraglomerular high pressure and high blood pressure. Perfusion and hyperfiltration states, delaying glomerular sclerosis and renal function decline. Therefore, children with chronic nephritis should have an appropriate protein intake, of which more than 60% should be high-quality protein, such as eggs, dairy products, lean meat, fish, etc. Low-phosphorus foods mainly include lotus root starch, vermicelli, cabbage, cabbage, egg white, celery, spinach, tomatoes, melons, sugar cane, etc. In addition, low-phosphorus can also be achieved by limiting protein intake.
2. Sufficient carbohydrates should be consumed
Since children with chronic nephritis limit protein intake, heat energy is mainly supplied by carbohydrates, so the amount of carbohydrates in the diet should be appropriate. Improve to meet the body's demand for heat energy. In addition, sufficient heat energy supply can reduce protein consumption, reduce the burden on the kidneys, and enable the small amount of protein ingested to be fully used for tissue repair, growth and development. Foods suitable for patients with chronic nephritis include vermicelli, vermicelli, potatoes, lotus root starch, etc.
3. Sodium salt intake should be limited
Chronic nephritis patients with obvious edema and hypertension should be given a salt-restricted diet, and sodium salt intake is generally required. The dosage is 1 to 3g per day. Children with chronic nephritis can increase or decrease the dosage according to the doctor's advice. Salted fish and various pickles should be avoided, and the amount of salt can be gradually increased after the edema subsides; eat more low-sodium foods, such as coix seed, rice, flour, zucchini, eggplant, cucumber, etc.
4. Appropriate amount of drinking water
The amount of drinking water is generally not restricted, but it should not be too much, especially for children with chronic nephritis who have obvious edema and oliguria, so they must Be careful about water intake.
5. Supplement vitamins and iron
Chronic nephritis patients may affect their vitamin intake due to long course of disease, poor appetite, and small food intake. Therefore, patients with chronic nephritis should pay attention to eating rich foods. Foods containing vitamins A, B and C, such as fresh vegetables and fruits, to prevent vitamin deficiency. Patients with chronic nephritis are often accompanied by symptoms of anemia, which is mainly caused by a lack of hematopoietic raw materials. Therefore, patients with chronic nephritis should also choose some iron-rich foods, such as pig liver, eggs, tomatoes, red dates, and green leafy vegetables. At the same time, pay attention to Folic acid and vitamin b12 supplement.
