i cannot find anything linking panic attacks to high blood sugars. it seems plausible that increases in stress hormones during a panic attack could temporarily increase blood sugars. your son's a1c and fasting glucose are normal so the high blood sugars are not caused by diabetes.
can a panic attack/hyperventialing cause blood sugar to rise? . my son had his glucose test for cf yesterday and while he was waiting for the 2 hour results he had a panic attack and began sobbing uncontrollably and hyerventilating because he was hungry and realized he couldn't eat for 2 hours (the clinic messed up and they had to put off his initial drinking of the glucose for 3 hours after he had already been there). anyway his fasting glucose was 86 his a1c was 5. 2 but when they did his post fasting it was 206.
