  • Pancreas does not able to produce enough insulin and causes diabetes.
  • Body does not properly respond to insulin (that is not sensitive to insulin), a condition called "insulin resistance", which causes diabetes
  • Or both shortage of insulin and insulin resistance.
Type 1 diabetes causes
Some genes may be behind the type 1 diabetes causes, but mostly it is triggered by the following:

  • Auto immune disorder, our body immune system itself attacks by mistakenly identified as enemy and destroys the insulin-producing cells of the pancreas. Thus pancreas losses its ability to produce insulin and can cause diabetes.
  • Pancreas beta cells damaged by cystic fibrosis or pancreatic surgery can cause high blood glucose called diabetes.
