Early symptoms and prevention of diabetes?

summary

With the improvement of the national living standard, the number of people suffering from diabetes has also begun to expand. It is understood that the number of diabetes patients in China has reached 40 million. Diabetes not only endangers the health of adults, but also becomes one of the common chronic diseases in children and adolescents. Therefore, targeted prevention of diabetes is the best way to prevent and treat diabetes. In order to improve our understanding of diabetes, let's introduce the early symptoms and prevention of diabetes?

Early symptoms and prevention of diabetes?

Polyuria due to high blood glucose, glomerular filtration of glucose can not be completely reabsorbed by the renal tubules, the formation of osmotic diuresis. The higher the blood glucose, the more urine sugar excretion, the more urine volume, 24-hour urine volume can reach 5000-10000 ml. However, in the elderly and patients with kidney disease, due to the disturbance of urine glucose excretion, polyuria may not be obvious when the blood glucose is mildly or moderately increased.

Polydipsia is mainly due to hyperglycemia, which makes the plasma osmotic pressure increase significantly. In addition, polyuria and excessive water loss lead to intracellular dehydration and aggravate hyperglycemia, which further increases the plasma osmotic pressure, stimulates the thirsty center and leads to thirst and polydipsia. Polydipsia will further aggravate polyuria.

The mechanism of overeating is not very clear. However, due to the absolute or relative lack of insulin or tissue insensitivity to insulin, the ability of tissue uptake and utilization of glucose is decreased in patients with diabetes. Although blood glucose is at a high level, the glucose concentration difference in arterial and venous blood is very small, and tissue cells are actually in a "hungry state", thus stimulating the feeding center and causing hunger and overeating; In addition, the body can not make full use of glucose, a large amount of glucose excreted from the urine, so the body is actually in a state of semi starvation, lack of energy also causes hyperappetite.

matters needing attention

Metformin, a hypoglycemic drug, and the side effects of Western medicine are very harmful to the human body. Therefore, strengthening the prevention of diabetes and regulating diet are the best methods. In order to prevent diabetes, we should pay attention to the following principles to control high sugar food. The focus of our daily diet is to eat more vegetables and coarse cereals, with a certain amount of high-quality protein food, such as lean meat, milk, eggs, fish, chicken, duck and bean products. In the choice of fruit varieties, edible fruit with low sugar content, such as green plum, watermelon, orange, lemon, plum, apricot, pineapple, strawberry, cherry and so on. For vegetables, it's better to choose fresh and pollution-free vegetables. Generally, the following vegetables are preferred: balsam pear, Chinese cabbage, rape, spinach, green pepper, leek, Luffa, wax gourd, cucumber, tomato, mung bean sprouts, eggplant, cabbage, onion, etc.
