Risk factors for diabetes depend on the type of diabetes.
Risk factors for type 1 diabetes
Although the exact cause of type 1 diabetes is unknown, factors that may signal an increased risk include:
Family history.Your risk increases if a parent or sibling has type 1 diabetes.
Environmental factors. Circumstances such as exposure to a viral illness likely play some role in type 1 diabetes.
The presence of damaging immune system cells (autoantibodies). Sometimes family members of people with type 1 diabetes are tested for the presence of diabetes autoantibodies. If you have these autoantibodies, you have an increased risk of developing type 1 diabetes. But not everyone who has these autoantibodies develops diabetes.
Dietary factors. These include low vitamin D consumption, early exposure to cow’s milk or cow’s milk formula, and exposure to cereals before 4 months of age. None of these factors has been shown to directly cause type 1 diabetes.
Geography. Certain countries, such as Finland and Sweden, have higher rates of type 1 diabetes.
