A risk factor is something that increases your likelihood of getting a disease or condition. It is possible to develop type 1 diabetes with or without the risk factors listed below. There are no known definite risk factors. However, the more risk factors you have, the greater your likelihood of developing type 1 diabetes. The main risk factors include the following:
Family History
If you have a parent, brother, or sister with type 1 diabetes, you (or your child) are at greater risk of having it, too. Scientists continue to believe that genetic factors play a role in the development of type 1 diabetes, but which genes is unclear.
Autoimmune Conditions
Type 1 diabetes is an autoimmune disease, caused by the body's immune system attacking the insulin-producing cells of the pancreas. You may be at a greater risk of developing type 1 diabetes if you have another condition that affects the immune system, such as:
Ethnic Background
You are at an increased risk of type 1 diabetes if your ethnicity is:
- Northern European
- Mediterranean
- African American
- Hispanic
Other Risk Factors
Other factors that may increase your child's risk of type 1 diabetes include:
- Cystic fibrosis
- Bottle-feeding or short duration of breastfeeding
- High birth weight
- Obesity during childhood
- Mothers age at childbirth (over 35 years)
