From Mechanicsville, Virginia, USA:

My son (17, Type 1 for 6 years) had a brief (5-6 second) blackout while driving. He came straight home (10 minutes) and checked his blood sugar. It was 174. He says he did not feel low. Is it possible that the scare caused his blood sugar to shoot up to the normal reading he got at home? Do you have any thoughts on the cause or do you know of similar causes?


It is not possible to answer your question over the internet. Seek individual medical attention concerning your son's blackout. If the blood sugar is checked a considerable time after the event it would be hard to know what happened.

Use this as an education time, to make sure your son checks his blood sugar before driving a car or doing anything else that might be dangerous if he is hypoglycemic. Always have food available in the car, and check the blood sugar at least every few hours if driving for extended periods.


Additional Comments from Dr. Tessa Lebinger:

As recommended, I would definitely report this episode to your doctor. It is also possible that the "black out" was unrelated to diabetes. Your son might have a seizure disorder or an arrythmia (irregular heart beat) that needs to be diagnosed and treated (and which would not be prevented by avoiding low blood sugars). He should not drive until the cause is found and his doctor says it is safe to drive.
