With the rapid development of China’s economy and the significant improvement of living standards, the incidence of type 2 diabetes in China has also shown a rapid growth trend. 2010 epidemiological survey shows that the prevalence rate of adults in China is 9.7% and the number of patients reaches 92 million, which has become the largest number of diabetic patients in the world. Long-term hyperglycemia can lead to multi-system damage, resulting in chronic complications of heart, brain, kidney, eye, skin, blood vessels and other tissues and organs. It brings heavy burden to the society and family, and seriously threatens human health. Therefore, early detection of diabetes and thus early treatment is especially important. So what kind of people are susceptible to diabetes, and what symptoms will indicate the possibility of diabetes at an early stage? A. Who is favored by type 2 diabetes? 1. People with a family history of diabetes: Type 2 diabetes has family aggregation, and couples with diabetes are more likely to have children with diabetes. 2, age factor: as age increases the prevalence of diabetes increases, over 45 years old is a high-risk group of type 2 diabetes. 3, obesity: eating too much high-fat food, or sedentary, lack of physical activity resulting in overweight or obesity, is an independent risk factor for type 2 diabetes. 4, diabetes during pregnancy or women who have given birth to a huge baby (more than 8 pounds): this group has an increased risk of developing diabetes later. 5, smoking, alcohol abuse: also an important risk factor for type 2 diabetes. 6, patients suffering from coronary heart disease, hypertension, hyperlipidemia, hyperuricemia: there are abnormalities in their lipid metabolism, which have common soil with diabetes, and have an increased risk of developing type 2 diabetes. 7.Patients with long-term mental tension and psychological stress: In the state of mental tension, the excitability of sympathetic nerves in the body is enhanced, and the secretion of insulin-resistant glucagon increases, which makes blood sugar rise. 8, unreasonable use of drugs: including the long-term application of thiazide diuretics, glucocorticoids and other drugs, can lead to diabetes. Second, what symptoms will suggest that may have diabetes? 1, abnormal urine: When you find more foam in the urine and it is difficult to dissipate or it is sticky and there are ants licking the urine, you should go to the hospital to test your blood sugar. 2.Change in living habits: When there is no obvious cause for thirst, excessive drinking, excessive eating, excessive urination with weight loss, or sweet taste in the mouth, blood sugar should be tested. 3.Slow wound healing: When there is skin breakage and the wound does not heal easily, blood sugar should be tested, because high blood sugar will affect the wound healing. 4.Unexplained lethargy: When there is no reason for lethargy and weakness, even in the resting state, the body feels tired. 5.Blurred vision: When there is no reason for abnormalities such as blurred vision of the eyes. 6, numbness and coldness of the fingers: When there is symmetrical numbness of the fingers without any obvious cause, you can test your blood sugar because diabetes can lead to peripheral neuropathy and peripheral vascular lesions.
