- Risk Factors
- There aren't many known risk factors for type 1 diabetes, though researchers continue to find new possibilities. Some known risk factors include:
- · A family history. Anyone with a parent or sibling with type 1 diabetes has a slightly increased risk of developing the condition.
- · Genetics. The presence of certain genes indicates an increased risk of developing type 1 diabetes. In some cases — usually through a clinical trial — genetic testing can be done to determine if someone who has a family history of type 1 diabetes is at increased risk of developing the condition.
- · Geography. The incidence of type 1 diabetes tends to increase as you travel away from the equator.
- · Viral exposure.
- · Low vitamin D levels. Research suggests that vitamin D may be protective against type 1 diabetes.
