Diabetes mellitus has been an important topic in the world of diabetes research. Although the cause of diabetes has not yet been fully elucidated, it is generally accepted from clinical point of view that diabetes is caused by a combination of genetic and environmental factors. It is worth mentioning that people with a family history of diabetes have a higher probability of developing diabetes than the general population. 1, diabetes is hereditary A large number of studies at home and abroad have shown that diabetes is hereditary. One study found that if one identical twin brother has type 1 diabetes, the other has a 50% chance of developing the disease in the future. The genetic predisposition to diabetes is more pronounced in patients with type 2 diabetes. 2. Is a family history of diabetes a guarantee that I will get diabetes? Although diabetes has a certain genetic predisposition, in most cases, it is the result of a combination of genes and is not simply passed from father to son or mother to child. Also, whether or not diabetes develops is influenced by environmental factors. Some people carry the disease-causing gene but will not develop it without the right external factors acting on it. For some people who have a family history of diabetes, they may have learned about it early in their family life and therefore started to intervene early through good lifestyle, in which case they are less likely to develop diabetes than people who do not have a family history but have an unhealthy lifestyle. 3. What can be done to prevent the onset of diabetes? Control your diet and live a regular life. Eat more coarse grains and vegetables, do not eat a lot of sugary substances at once, such as fruits and cakes, and eat less fatty foods, such as fatty meats and fried foods. Control the total daily calories, achieve balanced nutrition, and participate in more physical exercise. Maintain the ideal weight, especially pay attention to control the excessive growth of waist circumference. Maintain a positive and optimistic attitude towards life and work. For the majority of sugar lovers, there is no way to change genetics, so you can only try to change the environmental factors that cause diabetes. For example, choosing a healthy lifestyle and maintaining an appropriate weight can help reduce the probability of developing diabetes. Which sugar lovers are suitable for diabetes surgery 1.
