Question:

With a history of her father having diabetes, are the chances of my granddaughter being a diabetic? Does she need a glucose fasting test?

Answer:

If her father is known to have Type 1 or insulin dependent diabetes then the chances of your granddaughter getting it too is about 7%, rather less in fact if she is already 14 years old. If her father has Type 2 diabetes or Maturity Onset Diabetes in the Young and is being treated with diet and perhaps oral medication then her chances of becoming diabetic are a little higher; but not till much later in life. There is a National Diabetes Prevention Trial (DPT-1) for the first degree relatives of individuals who have Type 1 Diabetes and the local American Diabetes Association office could give you the telephone number of the nearest center involved in the trial. She could then be tested for antibodies which would be a definitive indicator of whether she might get diabetes. It would be very important though to discuss with her doctor and with other family members whether or not getting involved in such a test might adversely effect her depression. A random fasting blood sugar would not help much although if it was normal, it might be reassuring.
