Question 1

how many hours to fast before a fasting blood sugar level test?

Accepted Answer

Fasting: Depends on what's being measured but nothing after midnight for 8 am lab draw is adequate. Make sure you drink plenty of water.

Question 2

fasting blood sugar level almost the same as after 2 hours. what does this mean?

Accepted Answer

Good beta cells?: If i understand the question, your fasting glucose is the same as the glucose 2 hr after eating, or after a glucose load?  And both glucose levels are normal?  During a glucose tolerance test, or a meal tolerance test, it is common for the glucose to stay fairly flat, i.e. Not go up much. It means your Insulin response is very robust.  That is good.

Question 3

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

Accepted Answer

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.

Question 4

is 5.8 a high fasting blood sugar level? and how come after i eat, an hour later it's 4.0 and i feel a little off/ shakey? is this normal?

Accepted Answer

Slightly high: Hi. Yes, your fasting blood sugar is slightly high, but for diagnostics, you can't use finger stick glucose, you use serum glucose (drawn from a vein in your arm). Are you overweight/obese? If fasting serum glucose is 5.8 (or reproducibly above 5.5), you have prediabetes. You may be briskly secreting insulin in response to food intake, giving you your symptoms. Eat healthily and exercise regularly

Question 5

my fasting blood sugar level is 106 after 9 hours of my last meal i had at night.is this high?if it is high what diet should i take to control it?

Accepted Answer

High fasting glucose: Hi. Yes, that would be a high fasting glucose (upper limit of normal is 99). It should be repeated; if reproducible, you have impaired fasting glucose/prediabetes. Use serum glucose, not finger stick, for diagnosis. Healthy diet: whole grains, legumes, nuts, canola/olive oil, fruits &amp; veggies, lean meat, nonfat dairy; minimize fast food, processed food, saturated fat, white flour, white rice, etc.

Question 6

what to do if i check my fasting blood sugar level was 114 and 2 hours after meal was 169, am i diabetic?

Accepted Answer

Not necessarily: But your glucose are above normal, suggesting diabetes or at least prediabetes. The exact name doesn't matter. You need education, diet, exercise, weight reduction and probably medication. Check w/your doctor.

Question 7

what is a normal non fasting blood sugar levels?

Accepted Answer

High blood sugar: In most cases a blood sugar is high if greater than 200 mg/dl. A fasting blood sugar should be less than 126 mg/dl.

Question 8

my wake up (fasting) blood sugar levels vary greatly!  82 some days, 110 other days.  most common is high 90s.  are such fluctuations normal?

Accepted Answer

Blood sugar: Morning blood sugar varies depending on your diet,  morning stress or hormone levels. If it is  110 in the morning at times before eating, it may be pre-diabetes. Establishing care with a primary care doctor is a great way to prevent health care issues. I encourage you to find one.

Question 9

is having high fasting blood sugar levels but low hba1c good or bad?

Accepted Answer

Bad: High fasting blood sugars is bad and usually associated with high hba1c levels.
But very low levels may be harmful (say less than 6).

Question 10

what is a normal fasting blood sugar level?

Accepted Answer
