What is the blood sugar? Why does sugar enter the blood?
Many people don't understand that diabetes means that urine contains sugar, so how can it be linked to blood? How does sugar get into the blood? In fact, the detection of diabetes is the amount of sugar in the blood. Sugar is the source of human energy. Without sugar, the human body has no energy. When someone has low blood sugar, they will be weak and even faint.
Blood sugar is glucose in the blood, which is mainly obtained from food and is the main source of human energy. The activity of the body, the beating of the heart and the thinking of the brain are all inseparable from the blood sugar function. Sugar in food is the main source of blood sugar after digestion and absorption, and starch is also the main source of blood sugar, which can be converted into glucose under the action of starch re-amylase and glycosidase. There is a hypoglycemic drug called glycosidase inhibitor, which lowers blood sugar? Production? Capable
Without eating, some non-sugar substances can also be converted into glucose for supplementary supply under the action of gluconeogenesis.
We know where sugar comes from, but why is there no sugar?
There are three ways of blood sugar. Blood sugar can be used by tissues and organs, stored in the form of glycogen, and converted into extraordinary substances such as fat and unnecessary amino acids. When the food you eat absorbs more energy than your body uses, your body will store excess energy for a rainy day.
Some people like to go on a diet to lose weight, and they can really get satisfactory results soon. When the body has no energy, it will use its own inherent energy. Don't go on a diet after losing weight for a period of time. At this time, the body has a certain self-regulation ability, and will increase its storage when it is hungry for the next use. So this method of losing weight is very easy to rebound.
The last way of blood sugar is to excrete it from urine. When the blood glucose concentration is higher than 8.9 mmol/L (160 mg/100 ml), it will be excreted with urine to form glycosuria. Although the blood sugar of normal people is filtered by the glomerulus, it will be absorbed by the glomerulus, so the blood sugar in the urine of normal people is particularly small. Only when the blood sugar is higher than 8.9mmol/L, that is, it exceeds the reabsorption capacity of renal tubules, the urine sugar test is positive.
The diagnosis of diabetes is not based on urine, because if urine sugar is positive, it means that blood sugar is already high, and some people are positive in urine sugar, but their blood sugar is not high, such as pregnant women and the elderly. ?
