Understand how T1D develops
Autoimmune T1D can happen to anyone – understand the risks
People from all backgrounds are at risk of developing autoimmune T1D, even in adulthood and regardless of family history.
Some autoimmune or viral conditions can increase the risk
Although we don’t know the exact cause of autoimmune T1D, there are certain conditions that can increase the risk.
Having an autoimmune condition or a history of these conditions in your family has been associated with autoimmune T1D. These autoimmune conditions may include:
Many types of viruses can also increase the risk, such as:
- Coxsackievirus B (CVB)
- Rotavirus
- Mumps
- Cytomegalovirus (CMV)

Early-stage autoimmune T1D, or pre-symptomatic diabetes, is the phase before noticeable or visible symptoms. During this stage, type 1 diabetes has started, but the body can still produce enough insulin to maintain relatively healthy blood sugar levels.
There are specific autoantibodies, which are a type of protein in the blood that appear with type 1 diabetes, even before symptoms begin.
An autoantibody test is a blood test that can detect type 1 diabetes early by identifying diabetes-related autoantibodies. Detecting two or more of these autoantibodies suggests the early stages of type 1 diabetes. The test is typically done with a finger prick or blood draw.
Anyone, at any age, can develop autoimmune T1D, regardless of diet or exercise choices. If a person in your family has T1D, you have an increased risk.
Having an autoimmune condition in your family history has been associated with autoimmune T1D.
Access our autoimmune T1D risk assessment guide for more information about the factors that can put people at risk of autoimmune T1D.
If a person has autoimmune T1D, it will progress over time, whether or not they screen for it. Screening before symptoms appear arms you with knowledge so you can reduce your risk of DKA and prepare if tests detect early autoimmune T1D. You can talk to your doctor about next steps following your results.
