? Insulin is the only hormone in the body that lowers blood sugar. Insulin resistance is when, for various reasons, insulin becomes less efficient at facilitating glucose uptake and utilization, and the body works overtime to secrete more insulin to produce hyperinsulinemia, which is a condition that keeps blood sugar stable.
? This means that there is enough insulin in the body, but it doesn't work to lower blood sugar. Insulin is like a key that opens the lock on the cell, allowing glucose from the blood to enter the cell, oxidize and then provide energy to the cell, thus allowing the glucose concentration in the blood to decrease. But because the key doesn't match the lock, or the lock is rusty, no amount of insulin can lower blood glucose.
The causes of insulin resistance are also quite complex, and are mainly the result of both genetic and environmental factors***.
The genetic factor is nothing to write home about, as there may be mutations in the genes involved that prevent insulin from functioning properly.
More environmental factors, such as obesity (the most important cause of insulin resistance, especially abdominal obesity), long-term high blood sugar, micronutrient deficiencies, pregnancy, free fatty acids, long-term use of certain hormone drugs may increase the risk of insulin resistance.
Insulin resistance doesn't just lead to dysglycemia, it can lead to insulin resistance syndrome, also known as metabolic syndrome. Metabolic syndrome means that the body's proteins, fats, carbohydrates, etc. are not metabolized properly, resulting in a series of symptoms, which can be summarized as the "eight highs": high blood glucose, high blood lipids, high blood pressure, high blood viscosity, high uric acidemia, high fatty liver, hyperinsulinemia, and obesity.
Therefore, the harm of insulin resistance not only makes the sugar metabolism disorder, the whole body organs have different degrees of damage. So how do you know if you have insulin resistance?
You can see if you have the following characteristics, if there are three and more than three, it is likely that there is insulin resistance:
1, abdominal obesity, male waist >90 cm, female >80 cm.
2, Triglycerides ≥1.70 mmol/L.
3. High-density lipoprotein cholesterol (HDL-C) <1.036 mmol/liter (men) and <1.295 mmol/liter (women).
4. Blood pressure ≥130/85 mm Hg.
5. Fasting blood glucose >6.1 mmol/L.
6, Body mass index BMI>30kg/m2.
7, Hyperuricemia.
