Question
I am 50 years old. Several years ago, a blood test showed high blood sugar. However, six months ago, I had another test and the blood sugar level was 6.47. But a few days ago, I had another test and my blood sugar level rose to 8.18. Is this a recurrence of high blood sugar or due to a mistake in the test? Can blood sugar levels increase from 6.47 to 8.19 in just one month?
Answer
It is completely possible for blood sugar levels to rise from 6.47 to 8.19 within half a year. According to the information you provided, this is not a recurrence of high blood sugar but rather a progression of the condition. Since you did not receive systemic treatment or effective dietary control previously, the condition naturally worsened. Therefore, based on your current blood sugar levels, it can be confirmed that you have diabetes and require active medication treatment to prevent the occurrence of complications.
