The long-term blood sugar value HbA1c is a very important quantity for the evaluation of the blood sugar adjustment. This allows the doctor to assess how good the metabolism is and how to optimally design the therapy. According to the guidelines of the German Diabetes Society, he should be under seven percent in a well-adjusted diabetic.
The HbA1c value reflects the proportion of "sugared" red blood pigment (hemoglobin) in total hemoglobin. The HbA1c value shows what the average blood sugar level of the past three months was, regardless of whether the sugar levels have risen or fallen sharply in the meantime. A short-term change in diet, for example, the avoidance of sweets two to three days before the next visit to the doctor, therefore, has no effect on the long-term blood sugar.
What is the maximum HbA1c value?
In people without diabetes, the HbA1c value is between 4.5 and 6.5%. For diabetics, a HbA1c value that is as close to the norm as possible should be aimed for. At the latest when the HbA 1c value rises above 7%, action must be taken. Even if no complaints are noticeable.
Complication: late effects
80% of all diabetics do not die from their diabetes, but from the resulting secondary diseases. A high HbA1c value significantly increases the risk of subsequent illnesses such as heart attack and stroke, or damage to the kidneys or eyes.
