What Are Normal Creatinine Levels?

Creatinine is a toxin produced by muscle metabolism and is mainly eliminated by the kidneys. It also increases after a large amount of exercise or after eating a large amount of meat. If in this case creatinine is slightly higher than normal, don't worry too much, the index can return to normal after adjusting the diet.

Normal creatinine

Original

1. Water metabolism disorders: including polyuria, increased nocturia, thirst, dry mucous membranes, fatigue, etc .; or systemic edema, increased blood pressure, pulmonary edema, and heart failure.

2. Disorders of sodium metabolism: hyponatremia or hypernatremia.

3. Imbalance of potassium metabolism: hyperkalemia or hypokalemia.

4. Metabolic acidosis, patients may have deep and long breathing, lack of appetite, abdominal pain and nausea, vomiting, weakness, headache, restlessness and even coma.

5. Abnormal metabolism of aluminum, magnesium, copper, zinc, and selenium.

6. Renal osteopathy: bone pain and proximal muscle weakness; bone pain is usually systemic, the lower body holds heavy bone as the weight, and bone deformity can cause short stature.

7. Respiratory system disease.

8. Diseases of the circulatory system.

9. Digestive system lesions.

10. Hematological diseases, such as renal anemia and so on.

11. Infection.

12. Neuromuscular system lesions and skin symptoms.

13. Endocrine dysfunction, such as: thyroid dysfunction, sexual dysfunction, growth retardation, etc.

14. Metabolic disorders, such as: glucose metabolism disorders, lipid metabolism disorders, protein and amino acid metabolism disorders, metabolic waste retention, etc.

Renal failure compensatory period:

Assuming that the whole kidney function is 100% normal, the GFR of this period is 35% to 70% of normal (creatinine clearance is commonly used in clinical practice to reflect GFR). At this time, although the kidney's reserve capacity is reduced, the kidney's function can still maintain the stability of the body environment, clinically asymptomatic and azotemia (ie, normal blood creatinine). However, it should be noted that if the stages are simply based on creatinine clearance, there may be overlaps between stages. At this time, the value of creatinine is: 133-177umol / l.

Renal failure decompensation:

Also known as azotemia, referred to as renal failure, is the prelude to chronic renal failure. At this time, the glomerular filtration rate is reduced to the normal 21% to 35%, and the kidney's ability to maintain a stable environment in the body has been somewhat damaged. There can be varying degrees of azotemia, and the renal concentration function has mild damage (polyuria And nocturia), and may have mild anemia. Under normal circumstances, there are no obvious clinical symptoms and it is easy to be ignored. At this time, the value of creatinine is: 177-442umol / l.

Renal failure:

This time is also a more serious period, at this time the blood creatinine has reached 400umol / l or more. When GFR is reduced to 11% to 20% of normal, the internal environment of the body has been abnormal for a long period of time, significant azotemia and anemia are apparent; the concentration function is obviously impaired (isotonic urine, nocturia ), And water and electrolyte imbalances, such as mild or moderate metabolic acidosis, water retention, hypocalcemia, hyperphosphatemia, etc., generally no hyperkalemia. May have mild gastrointestinal, cardiovascular and central nervous system symptoms. At this time, the value of creatinine is: 442-707umol / l.

Uremic phase:

This is the last stage, the uremia stage. At this time, the serum creatinine has reached the terminal stage. When the above-mentioned renal failure phase develops further, the remaining GFR is only less than 10% of normal, that is, the symptoms of uremia, high creatinine, the clinical manifestations of the above-mentioned renal failure are more obvious, and severe systemic symptoms appear. In particular, gastrointestinal, cardiovascular and nervous system symptoms are more prominent. How much creatinine is uremia? When the creatinine develops to greater than 707umol / l, it has been stated that it is the end of uremia, at this time, the patient's kidney function has been basically completely damaged.

1. Limit of salt:

Generally, patients with renal insufficiency stage and azotemia stage have high blood creatinine and begin to show various mild clinical symptoms. However, due to moderate pathological damage, hypertension and edema can be controlled with or without salt. Intake, given a low-salt or salt-free diet.

2. Protein supply:

Protein supply: Due to azotemia and renal insufficiency in patients who are rescheduled, in order to control the continued deterioration of renal function, protein intake should be controlled and a diet rich in high-quality protein should be selected.

3. Vitamin intake:

Patients with high creatinine in renal failure should choose foods rich in vitamin A, vitamin B2, and vitamin C.

If renal insufficiency is only high in creatinine with renal failure, but patients without oliguria and edema can not help but salt and water, maintain a low salt diet. If there is severe edema, and high blood pressure or even heart failure, salt prohibition should be strictly restricted.

4. In addition to diet, patients with high creatinine should also pay attention to restrictions on smoking and alcohol. Because the poisoning of tobacco and alcohol is mainly to the kidneys and blood vessels, the more smoking and drinking, the greater the damage to the renal blood vessels, the earlier the aggravation of renal arteriosclerosis, and the better the glomerular sclerosis, so whether the renal function is normal Patients with high levels of creatinine or renal dysfunction must strictly abstain from smoking and alcohol to avoid greater kidney damage.

Traditional Chinese medicine "Yun Huo Huo Ren" is based on the meridian acupuncture points. It burns or irons a certain part of the body surface. The fire is mild and long-lasting. It is easy to penetrate deep into the skin. The fire of fate, igniting fire, and warming the kidney-yang to regulate the nature of the growth of the kidney, so that kidney disease is gradually getting worse.

Traditional Chinese and Western medicine are two different medical systems developed under different historical conditions and different cultural backgrounds. Traditional Chinese medicine nephrology inherits and promotes the basic theories of traditional Chinese medicine kidney disease, combining modern medicine's understanding of disease and traditional Chinese medicine. The research results of pharmacology, according to the theory of syndrome differentiation and treatment of traditional Chinese medicine, organically combine disease differentiation and syndrome differentiation to achieve complementary advantages of traditional Chinese and western medicine.

(1) Avoid eating foods high in potassium. If the potassium content in the body rises, it will break the balance of trace elements in the body, easily cause edema, and make it difficult to control kidney disease. Therefore, patients with high creatinine must avoid eating too many potassium-containing foods, such as watermelon, onion, pineapple, winter melon, orange and so on.

(2) Avoid eating high-fat foods, greasy foods are not easy to digest, and will cause patients with elevated blood lipids, which will harm the health of patients with high creatinine, so patients should eat less greasy and fried foods, and use less oil when cooking.

(3) Limit salt. Generally, patients with high creatinine often show symptoms of edema and hypertension of different degrees, so patients should control the intake of salt.

Secondly, attention to the daily care of patients is also one of the main measures to reduce creatinine.

(1) Reduce excessive physical and mental work and ensure adequate rest time.

(2) Use drugs with caution, especially nephrotoxic drugs. Because general drugs must be dissolved in the blood to exert their normal effects. When the blood flows to the kidneys, the residual effects of the drugs will adversely affect the kidneys. Therefore, patients with high creatinine must use the drugs with caution. Blind medication.

(3) Regular inspections and regular physical examinations are particularly important for patients with high creatinine treatment at home. Because patients cannot be informed of the situation of the patients in a timely manner, they must regularly go to the hospitals for physical examinations to facilitate doctors to make appropriate adjustments to treatment. It is more beneficial to the treatment of patients.
