Fasting blood sugar can be checked if you don't eat it, but if you eat it, you can check it, which means different things. It is best to have a full examination: once on an empty stomach, 2 hours after meals.
Blood lipid is the general name of neutral fats (triglycerides and cholesterol) and lipids (phospholipids, glycolipids, sterols and steroids) in plasma, which widely exists in human body. They are essential substances for the basic metabolism of living cells. Generally speaking, the main components of blood lipids are triglycerides and cholesterol, among which triglycerides participate in energy metabolism in the human body, while cholesterol is mainly used to synthesize plasma membrane, steroid hormones and bile acids.
Blood lipid examination:
1, serum total cholesterol
[Normal reference value]
2.9-6.0 mmol/L 。
[Clinical significance]
This increase is seen in nephrotic syndrome, atherosclerosis, common bile duct obstruction, gallstones, biliary tract tumors, diabetes, mucinous edema and so on.
This decrease is seen in hyperthyroidism, pernicious anemia, acute severe hepatitis and liver cirrhosis.
2. Serum cholesterol ester
[Normal reference value]
2.34-3.38 mmol/L 。
[Clinical significance]
It can be reduced in liver parenchymal diseases, which indicates that the development and prognosis of the disease are poor.
3. Determination of serum phospholipids
[Normal reference value]
1. 10-2. 10 g/L.
[Clinical significance]
It is increased in diseases such as liver cirrhosis, diabetes and hypertension.
It decreases in hyperthyroidism, hemolytic anemia and other diseases.
When detecting fasting blood lipids, venous blood must be taken on an empty stomach 12 hours or more. Non-fasting blood samples can increase blood lipid content, especially triglycerides. If you want to specifically detect postprandial blood lipids, that is another matter. Avoid eating high-fat food, drinking and smoking in the last meal before blood test to avoid errors in test results. When the physiological and pathological conditions are relatively stable, there should be no acute attack within 4 ~ 6 weeks. After acute myocardial infarction 12 ~ 24 hours, the blood lipid level of hyperlipidemia patients began to drop sharply, so it could not reflect the blood lipid level before the onset. In addition, do not test blood lipids when taking certain drugs, such as birth control pills, antihypertensive drugs such as propranolol and thiazide diuretics, which will increase blood lipid levels.
Their differences:
The blood concentration of hyperlipidemia is too high, and hyperglycemia means that the blood sugar content is too high (popular enough)
In fact, patients with hyperlipidemia and hyperglycemia have taboo foods, which is the view of western medicine and an' ignorant Chinese medicine'. Hyperlipidemia and hyperglycemia are due to the fact that nutrients and sugar in the body cannot be separated from the blood and reach the parts needed by the body, that is to say, nutrients and sugar are in the blood, but they cannot be obtained where they are really needed! However, most people think that there is "overnutrition" in the body, and excess nutrients and sugar have gone into the blood. We should do everything possible to reduce the intake of nutrients and sugar, so taboo foods have appeared.
Hyperlipidemia and hyperglycemia are all caused by too much nutrients and sugar in the blood, but why do people only see blood without considering the nutritional status of the body?
The physical condition of patients with hyperlipidemia and hyperglycemia belongs to yin deficiency or yin and yang deficiency (serious deficiency of qi and blood) in traditional Chinese medicine. The body is seriously lacking in nutrition and is already very weak. Any' taboo food' will only make the body collapse more and more.
Hyperglycemia is not necessarily diabetes. The real diabetes is the decrease of insulin secreted by the pancreas. Hyperglycemia is not necessarily diabetes, and the harm of diabetes is not hyperglycemia. This is an increase in blood viscosity.
Clinically, patients with liver cirrhosis have hyperglycemia symptoms, hyperthyroidism patients have hyperglycemia symptoms, and cancer patients have hyperglycemia symptoms. In the end, there were no vascular embolism complications such as coronary heart disease, cerebral thrombosis and angiitis obliterans, because there was no increase in blood viscosity in these primary diseases.
Because diabetes is not only a problem of high blood sugar, but also a problem of where blood sugar goes. Western medicine believes that it will be safe to give hypoglycemic drugs and synthesize blood sugar into glycogen. In fact, hypoglycemic drugs turn blood sugar into fat during metabolism. These fats are deposited on the blood vessel wall, causing arteriosclerosis and inevitably causing embolism.
