I will be on a liquid diet for 24 hours prior to surgery. Should I continue to monitor carbohydrate intake during this time?
Definately stop taking the Metformin at least two day before your surgery. During your stay at the hospital they will control your blood sugar with insulin. Additionaly, wait until you have recovered from your surgery until you start back up your met regimen. The issue is that when you are dehydrated, as often is the case following sugery, lactic acidosis (a build up of lactic acid in the body) can become an issue. This can be a potentially fatal condition. As far as the Actos is concerned, tell your doctor, surgeon and anaesthetist that you have are taking it because it may affect other medecines used during surgery. Most likely they will tell you to stop taking it a few day prior to sugery so that you can 'washout' and they will keep you controlled via insulin. Hope this helps. And good luck with your sugery.
