I can understand your concern for your son, because there is a family history of diabetes/prediabetes. His
blood sugar seems to be within the normal
limits. The
fasting sugar of 109 is on the higher end of that, but less than 110 is not considered elevated. The 116 after eating is well within normal limits. Rather than continuing to test your son's blood sugar at home (something a 12 year old boy is going to tire of quickly) I would recommend mentioning your concerns to the pediatrician.
