Question from Salt Lake City, Utah, USA:

My husband has had type 1 diabetes since he was nine months old. Given how young he was when diagnosed, does my daughter have more than a 6% chance of getting it? She is 10 years old. Also, he has a daughter from a previous marriage that has had type 1 since she was 10 months old. Does this increase my daughter’s risk as well? She has had a blood test, with a glucose level of 4, which I understand is perfect. Should I have her blood tested once a year at her annual check-up just as a precaution? She has unexplained bouts of vomiting, nausea, and extreme hunger, but not thirst and frequent urination. She has outgrown a number of food allergies from infancy. What role might this have in her contracting type 1? I have read through your other questions and answers and can’t find much on this.
