Source of information: experts on the website of China Pharmaceutical Association suggest that you learn to check your diabetes: some people feel healthy. Like losing weight. The symptoms of diabetes are probably two big pieces. One piece is called three more and one less. What do you mean by three more? It's called urinating, eating and drinking. Exceed normal people or the original situation. At the same time, weight and physical strength have also decreased. Weight and physical strength decline is called a little. Most diabetics don't necessarily lose weight, but they are a little thinner than when they are heaviest. As long as you find yourself eating more and drinking more than before, but your physical strength is not good, many people's actual blood sugar has reached the standard of diabetes. Then the second one is that some people have hypoglycemia before meals, and he has no symptoms of thirst, excessive drinking and polyuria. But he just felt very hungry before dinner, and this meal could not wait for the next one. If I don't eat something, I will be flustered by hunger. Some people say that he rides a bike after work and must buy food on the way, otherwise he can't go home. This is probably due to slow insulin secretion. Slow insulin secretion is not synchronized with hyperglycemia. When blood sugar is low, insulin is high, which leads to this symptom. There are also some complications. For example, the skin itches and boils easily, and there is a sign called black spot in front of the tibia. I have a black spot on my leg. It won't disappear soon. It hasn't disappeared. The other piece is black. The front of the leg is black. Many people with diabetes have this kind of performance. There is also poor eyesight. I can't see clearly far and near, which is not necessarily an ophthalmic complication. But because of high blood sugar and eye damage, patients always can't see clearly. Of course, there are also some complications, such as cataracts and retinopathy. Growth and development are also affected. For example, children with diabetes will affect their growth and development. Don't give up these clues. In fact, as long as you have diabetes, there are only unexpected things, and there is nothing you can't find out. If you want to check a drop of blood, you can find it. Don't delay. Any disease, including AIDS, is said to be cured sooner or later. Diabetes will be cured one day, but not now. It is an exaggeration to say that it can cure diseases, or it is a fake medicine of witch doctors, which is a lie.
