Causes of type 1 diabetes:
(1) virus infection
Many scientists believe that viral infections can also cause type 1 diabetes.
This is because the virus infection in patients with type 1 diabetes before the
onset of a period of time is often too, and type 1 diabetes "epidemic" often
appear after the virus is endemic. Viruses, such as those that cause mumps and
rubella virus can cause polio, Coxsackie virus family, can play a role in type 1
diabetes
(2) genetic factors
The present study data show that the genetic defect is the basis of the
incidence of type 1 diabetes, this genetic defect is manifested in the people on
chromosome 6 HLA antigen abnormalities. The characteristics of the familial
incidence of type 1 diabetes, if a family's ancestors, parents have a history of
diabetes, then compared to people with no such family history, their offspring
are more susceptible to the disease.
3's own immune system defects
To detect a variety of autoimmune antibodies in the blood of patients with
type 1 diabetes, such as glutamic acid decarboxylase (gad antibody), islet cell
antibodies (1ca antibody). These abnormal autoantibodies can damage human islet
insulin secretion from b cells, not normal insulin secretion.
