You are receiving this information sheet because tests for your surgery have revealed that you have some insulin resistance or prediabetes. Prediabetes refers to blood sugar levels that are higher than normal, but not high enough to make a diagnosis of diabetes. Not everyone with prediabetes will develop type 2 diabetes, but many will. This is a warning sign to start making lifestyle changes to prevent, or at least delay, the onset of diabetes.

Diagnosis of pre-diabetes
A diagnosis of prediabetes can only be made by a laboratory blood test. The table below shows the diagnostic values for prediabetes and diabetes.


  Pre-diabetes Type 2 diabetes
Fasting blood glucose Between 6.1 and 6.9 m m o l / L 7.0 mmol/L and above
Glycated hemoglobin (HbA1c) Between 6.0 and 6.4 6.5% or more
Blood glucose measured at any time of the day 11.1 mmol/L and above, with symptoms


The good news is that it has been shown that changing one’s lifestyle habits can reduce the risk of developing type 2 diabetes by nearly 60%, or at least delay its onset, as well as the associated complications. Please refer to the fact sheet we have prepared for this purpose.

Why treat it?
High blood sugar in the period after surgery increases the risk of infection, wound healing problems, and other complications. It is therefore very important for us to optimize your blood sugar control before and after your surgery.

Before your operation
A change in your lifestyle and diet is often very effective (see the sheet we have prepared for this purpose). The addition of medication in pill form (oral hypoglycemics) may be necessary.
Upon your arrival at the Clinic
You will be identified as a patient at risk for high blood sugar (diabetes). This should not surprise you.
Your blood sugar will be tested regularly.
Your meals will be adapted to your condition (low in simple sugars).
After your operation
If your blood sugar rises significantly, we will give you insulin by injection. This is the most effective way to reduce your blood sugar to
a favorable level.

Return home
It will be important to maintain your healthy lifestyle habits: low sugar diet, regular physical activity, moderate alcohol consumption, etc. You will need to inform your general practitioner that you have been identified as pre-diabetic. Your general practitioner will be able to monitor your condition and decide if long-term treatments are needed.
The Duval Clinic team is proud to offer you optimal and safe care.
