What is the cause of diabetes

The causes of diabetes are complex, and may be caused by genetic factors, environmental factors, autoimmune factors, age and other reasons. First, genetic factors Genetic factors play an important role in the onset of diabetes. If there are diabetic patients in the family, especially immediate relatives, the individual's risk of diabetes will increase. Some gene variants may lead to pancreatic beta cell dysfunction or insulin resistance, thus contributing to the occurrence of diabetes. Second, environmental factors Poor lifestyle, such as high calories, high fat, high sugar diet, lack of exercise, long-term sitting, etc., easily lead to obesity, and obesity is an important risk factor for triggering type 2 diabetes. In addition, environmental chemicals, viral infections, etc. may also affect the function of islet cells. Third, autoimmune factors In type 1 diabetes, autoimmunity plays a key role. The body's immune system mistakenly attacks islet beta cells, resulting in reduced numbers and loss of function of islet beta cells, which in turn fails to secrete enough insulin to maintain normal blood sugar. 4. Age Increase With age, islet beta cell function may gradually decline, insulin secretion is relatively insufficient, and the body's sensitivity to insulin may also decline, increasing the risk of diabetes. In addition, stress conditions, including severe mental trauma, long-term stress and high pressure, may lead to elevated blood sugar; the use of certain drugs may also induce diabetes. Understanding these causes helps to better prevent and control the occurrence and development of diabetes.
