Is 11 hours fasting fine for fasting blood sugar level test or is too much and will give inaccurate reading or lesser reading?

Sounds fine: A variety of blood tests gives more accurate results if the patient has not eating food, drank beverages other than water, or taken certain medications that might influence test results. For checking fasting blood sugars, a patient can fast overnight (about 10 hours, but 8-12 hours should be fine) and then give his blood sample before taking his morning vitamins or medications. ...Read more

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

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. ...Read more

Fasting blood sugar level was 110. Typically in mid 90s. Was nervous/anxious just prior to test. Could this cause a spike? At home I'm always ~82.

Calibration?: Cortisol has been associated with stress & blood sugar; however, the variations are relatively small & can fluctuate throughout the day. Similar to blood pressure readings, which may rise in the doctors office due to stress, a blood sugar reading in the office should be checked more than once, & taken in context, when deciding to treat it. A hemoglobin A1C can show 3 month average blood sugar. ...Read more

Fasting blood sugar level is 6.3. The 3 month average test is normal. Does this mean I am pre diabetic?

Impaired: This is called "impaired fasting glucose", and statistically you have a higher than average chance of getting diabetes, hence the term "pre-diabetes". But now is the time to do something about it: weight loss, exercise, healthy living. You can reverse this. ...Read more

Why is glucose screening test done exactly at 1hr? Does blood sugar level only peak then? After that does it drop or can it increase further?

Why is glucose screening test done exactly at 1hr?  Does blood sugar level only peak then? After that does it drop or can it increase further?

Just a standard way.: Blood glucose testing can be done prior to eating (when you are fasting) and the "1 hour after" is only because it has been done this way for many years and will give a typical indication of your response to eating. It can go much higher in some diabetics and even higher in normal people at an hour after eating. The usual and in my view better indication of your blood sugar status is the HgbA1c ...Read more

Thirsty: One cause of night time dry mouth is having nasal congestion, which causes mouth breathing while sleeping. Also, be sure you avoid diuretics (medicines which induce urination) in the hours before bedtime. Lastly, "dry mouth" is sometimes a side effect of a medication. ...Read more
