My son is 9 and he got dizzy today so I checked his blood sugar, (I have a glucometer from when i was pregnant with my youngest one) I did the test for the control it was 94 and my sons was 164 I waited until 2 hours of no food drink at least (closer to 2 1/2) and checked it again and it's 168. I'm worried about this. I am going to check it again in a few minutes when it's been an hour after dinner but what should it be 1 hour after eating? and how bad is this?
