The cause of type 1 diabetes isn’t known, but some researchers think an inherited gene might trigger a virus. You or your child may be at a higher risk if:
You have a family history. Certain genes increase the odds of developing type 1 diabetes.
You live in certain environments. Studies show there may be a link between cold climates and type 1 diabetes.
You may have had exposure to other viruses. Some researchers are studying a connection between enteroviruses that cause mild illnesses (like the common cold) and the role these viruses may play in damaging the pancreas and triggering type 1 diabetes. More research needs to be done, but the studies are promising.
