Every November 14 is the United Nations diabetes Day. People with diabetes often smell sugar and turn pale. Many healthy people also start to worry about whether they will get diabetes if they eat too much sweets? In this regard, the reporter of Renmin. com interviewed Wang Fang, the chief physician of the Department of Endocrinology of the Third Xiangya Hospital of Central South University. "There is no obvious causal relationship between sugar consumption and diabetes." Wang Fang introduced that diabetes is a group of metabolic diseases characterized by chronic hyperglycemia caused by a variety of causes. Hyperglycemia is caused by insulin secretion defect or impaired biological function, or both. Wang Fang said that at present, the etiology and pathogenesis of diabetes have not been completely clear. It is generally believed that diabetes is caused by genetic factors and environmental factors. Hereditary factors refer to family history of diabetes, such as parents and grandparents with diabetes. Environmental factors include the infection of some viruses, or the acquired bad lifestyle, such as long-term high calorie diet and inactivity. "A person with normal genetic background and fully normal islet function will not suffer from diabetes due to excessive sugar consumption." Wang Fang suggested, however, that if you eat too much sugar and don't pay attention to exercise for a long time, it may lead to obesity, which is a risk factor for diabetes. Therefore, even healthy people should eat sugar properly, and it is not recommended to eat more. Wang Fang said that diabetic patients often have symptoms such as excessive drinking, eating, urination and weight loss, which are referred to as "more than three but less" symptoms. However, some patients may not have any symptoms at the early stage of the disease, but only be found during physical examination. The main harm of diabetes is its complications. Long term hyperglycemia will cause dysfunction of brain, heart, blood vessels, kidneys, eyes, nerves and other organs and tissues of the whole body, leading to chronic complications. In severe cases, acute complications such as diabetes ketoacidosis, hyperglycemia and hyperosmolarity may occur. So, how can we prevent diabetes? Wang Fang said, first of all, we should develop a reasonable eating habit, try to avoid high calorie, high sugar, high salt diet in daily life, and choose more foods with high dietary fiber. Secondly, we should develop good living habits, such as smoking cessation, alcohol restriction, weight control, etc. In addition, proper exercise is essential to prevent diabetes. It is recommended to keep 30 minutes of exercise every day, 5 to 6 days a week. At the same time, we should maintain a positive and optimistic attitude. Finally, we should do a good job in regular physical examination, check blood glucose level regularly, and achieve early detection, early diagnosis and early treatment. (Outlook New Times)
