November 14th is "United Nations Diabetes Day". As the largest country of diabetes, China has exceeded 129 million 800 thousand, and this figure is still rising. At present, diabetes has become a public health problem to be solved in the whole society. Lack of exercise, "three high" diet, smoking, drinking, staying up late... Unhealthy lifestyle leads to the increasing incidence rate of diabetes and showing a younger trend. Causality between obesity and diabetes mellitus Excessive intake of nutrients over a long period of time leads to obesity, which leads to dyslipidemia, metabolic abnormalities, and eventually diabetes. At present, in China, 70 million of the patients with diabetes and obesity. For obese people, obesity itself will lead to insulin resistance and hinder the combination of insulin and insulin receptor. If it cannot be combined, it will not be able to transfer blood glucose to cells. Therefore, the more obese the more insulin resistance, the more insulin imbalance will be caused. If insulin secretion is reduced or its function is impaired, and the hormone regulating blood glucose cannot be controlled, it will cause blood glucose to rise. 2 diabetes development can be divided into three stages. The first stage is called high-risk group. The second stage is called pre diabetes, and the third stage is diabetes. The "high-risk" and "pre" population of diabetes accounts for a high proportion of the population. How to make the pre diabetes population not develop into diabetes, so that diabetic patients do not develop complications, which requires people to take the initiative to pay attention to their blood sugar, weight and so on. Diagnosis of diabetes mellitus Whether a person is suffering from diabetes needs to measure two blood sugar. One is fasting blood glucose, which refers to the fasting blood glucose before breakfast. Another indicator is blood glucose two hours after meal. Blood glucose is monitored two hours after meal. If fasting blood glucose gt; 6.1mmol/l or two hours after meal blood glucose gt; 7.8mmol/L, but if the value has not yet reached the diagnostic criteria of diabetes, this condition is known as pre diabetes. Such people can become diabetic at any time. Diabetes complications are dangerous. Complications of diabetes include retinopathy, uremia, foot disease and so on. In addition, the risk of cardiovascular and cerebrovascular diseases in diabetic patients is 2 - 4 times higher than that in non - diabetic patients of the same age and gender. The risk of acute myocardial infarction is six times that of normal people, the risk of reinfarction can reach 40%, and the life expectancy is one third lower than that of their peers. 70% of diabetic patients die from cardiovascular disease. Professionals suggest that patients with diabetes must be actively treated and properly treated. At the same time, we should prevent and treat early, eat reasonably, work and rest on time, and participate in more outdoor sports. (outlook new era)
