 [ Symptoms ] my blood levels have ranged from 80 90 today it was 67 could i have diabetes  my father is diabetic and he gave a tester so i could monitor it about a month ago i noticed that i would feel weak shaky sweaty and like i was about to pass out so i asked him if it could be a low blood sugar and he said it sounds like it this was the first time since i have been monitoring it that i have felt like that so i checked it and my blood sugar was 67 [ Disease ] based solely on those readings your blood sugar readings on that day do not indicate any levels that would be consistent with diabetes
