Early symptoms of diabetic glomeruli?

summary

Middle aged and old people are more vulnerable to diabetes, which affects people's daily life. So the prevention and treatment of diabetes is very important. Do you know the early symptoms of diabetes? Let's get to know!

Early symptoms of diabetic glomeruli?

1. Polyuria due to high blood glucose, beyond the renal glucose threshold (8.89-10.0mmol / L), the glucose filtered through the glomerulus can not be completely reabsorbed by the renal tubules, forming osmotic diuresis. The higher the blood glucose, the more the urine sugar excretion and the more the urine volume. The 24-hour urine volume can reach 5000-10000 ml. However, in the elderly and patients with kidney disease, the renal glucose threshold is increased, and the urine glucose excretion is impaired. When the blood glucose is slightly or moderately increased, polyuria may not be obvious.

2. Polydipsia due to hyperglycemia makes plasma osmotic pressure significantly increased, coupled with polyuria, excessive water loss, the occurrence of intracellular dehydration, aggravating hyperglycemia, making plasma osmotic pressure further increased significantly, stimulating the thirsty center, leading to thirst and polydipsia. Polydipsia further aggravates polyuria.

3. Polyphagia most scholars tend to be caused by the decrease of glucose utilization rate (the difference of glucose concentration in arterial and venous blood before and after entering and leaving tissue cells). During fasting, the difference of glucose concentration between artery and vein blood in normal people is reduced, which stimulates the feeding center and produces hunger; 829 mmol / L), the feeding center was inhibited, the satiety center was excited, and the feeding requirement disappeared.

matters needing attention

High sugar food should be controlled. The focus of 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.
