Environmental factors: Although type 2 diabetes has genetic factors, not everyone with diabetes genes will suffer from diabetes. This is called genetic susceptibility, not genetic disease. Whether this genetic tendency is manifested or not is directly related to the acquired environmental factors.
Genetic problems of diabetes:
1.2 type diabetes has obvious heredity, especially parents, siblings and children of diabetic patients, who are more prone to diabetes.
2. 1 The first-generation relatives of patients with diabetes refer to brothers, sisters and children. Their risk of diabetes is 10 times higher than that of the general population, but 95%-97% of them may not have diabetes. In addition, if the insulin release test shows that insulin release is reduced, 1 type diabetes should also be prevented.
3. Newborns are too thin and fat, and it is easy to get diabetes in the future.
Obesity, unreasonable diet and decreased physical activity are important environmental factors of type 2 diabetes and insulin resistance. The incidence of diabetes in overweight people is 2.9 times that of normal weight people, and the risk of diabetes in women with body mass index between 23 and 25 is four times that of women with body mass index less than 22. The risk of developing type 2 diabetes is 93.2 times that of people with a body mass index greater than 35 compared with those with a body mass index less than 22. /kloc-people who gain 7 ~ 10.9 kg after 0/8 years old have an increased risk of type 2 diabetes 1 fold. Obese women lose more than 5 kilograms in 10 years, and the risk of diabetes can be reduced by more than 50%.
Some people, especially the elderly, lack of chromium may also be the cause of diabetes. Being underweight in infancy is prone to diabetes in adulthood, and obesity is an important factor of insulin resistance.
