Life is a matter of life and has little to do with metaphysics. This is a genetic problem. First of all, let's understand diabetes, which is a group of metabolic diseases characterized by hyperglycemia. Hyperglycemia is caused by defective insulin secretion or impaired biological function or both. Long-term hyperglycemia in diabetes mellitus leads to chronic damage and dysfunction of various tissues, especially eyes, kidneys, heart, blood vessels and nerves.
1. Genetic factors
1 type or type 2 diabetes mellitus has obvious genetic heterogeneity. Diabetes has a tendency of family onset. 1/4 ~ 1/2 patients have a family history of diabetes. At least 60 genetic syndromes can be associated with diabetes. There are many DNA loci involved in the pathogenesis of 1 diabetes, among which the polymorphism of DQ locus of HLA antigen gene is the most closely related. Many obvious gene mutations have been found in type 2 diabetes, such as insulin gene, insulin receptor gene, glucokinase gene and mitochondrial gene.
2. Environmental factors
Obesity caused by overeating and decreased physical activity are the most important environmental factors of type 2 diabetes, which makes individuals with genetic susceptibility to type 2 diabetes prone to illness. 1 The immune system of diabetic patients is abnormal. After being infected by Coxsackie virus, rubella virus, parotid virus and other viruses, it leads to autoimmune reaction and destroys insulin β cells.
As can be seen from the above, five of the six daughters have diabetes, and such a high prevalence rate can basically be judged to be inherited from the previous generation. If you go back to check the family history, it should be that your parents or grandparents' relatives had diabetes before.
If there are no diabetics near your home, the possibility of eating habits is very small.
