Does the anxiety and the stress effects the sugar blood level test result ? and if did the test in the morning but i felt that my stomach is not empty

Yes: Yes to both questions. Anxiety and stress raise cortisol levels and Epinephrine is induced which increases blood sugar levels. Hey fasting glucose is greater than 12 hours without eating or drinking sweet drinks. If you had been eating for greater than 12 hours from the test or you were stressed this will raise your blood glucose levels and give you an artificially high reading blood glucose level.
