Question
I am 50 years old. Several years ago, a blood test showed that my blood sugar was high. However, half a year ago, I had another check-up and my blood sugar level was 6.47. But a few days ago, I checked again and my blood sugar increased to 8.18. Is this a recurrence of high blood sugar, or could there have been a mistake in the test? Can blood sugar levels increase from 6.47 to 8.19 in just one check-up?
Answer
Based on the information you provided, it is entirely possible for your blood sugar to have risen from 6.47 to 8.19. This is not due to a testing error but rather an escalation of your condition. Since your blood sugar was already abnormal half a year ago and you have not received systematic treatment or effective dietary control, it is possible that you are developing diabetes. Therefore, it is recommended that you actively pursue medication treatment to prevent complications.
