How Often Should You Check Blood Sugar When You Have a Wound?

Active diabetic wounds require more frequent blood sugar monitoring than usual. Check fasting glucose every morning to track overnight patterns. Test two hours after each meal to catch problematic food spikes. Monitor before bed to ensure safe overnight levels. Check anytime you notice wound changes like increased redness or drainage. Infection often causes unexpected glucose spikes—this can be your first warning sign. Blood sugar control on wound healing means testing 4-6 times daily until wounds close completely. This frequency catches problems early and shows how food and activity choices affect healing. Document every reading to identify patterns affecting your infected diabetic wounds.
