Normal Fasting Blood Sugar Levels
Normal fasting blood sugar level is the most essential indicator of your body’s ability to process glucose, as during the day your blood glucose levels may fluctuate because of meals or snacks you have. Accordingly, a fasting blood sugar test (FBS) is still the most popular method of estimating one’s overall glucose homeostasis because it eliminates all the intakes that might affect the result. Fasting blood glucose test should be taken after at least 8 hours of fasting (no food is allowed, only water), that’s why early morning in the best time to measure your fasting levels.
If your fasting test shows more than 125 mg/dL once, you won’t be diagnosed with diabetes immediately. Your doctor will tell you to take the test once or twice more. If the result is stable then you will be diagnosed with diabetes. If fasting blood glucose is normal after the fasting glucose tests, then you may be recommended to correct your diet or have additional tests in a certain period of time. Today, many doctors agree that normal fasting blood sugar range is 83 mg/dl (4.6 mmol/L) or less, althouth some doctors say 5.6 mmol/L (100 mg/dL) is admissible. Most healthy people have their normal fasting blood sugar levels ranging 70 mg/dl (3.9 mmol/L) to 80 mg/dl (3.9 mmol/L).
Please, note that the fasting blood sugar ranges accepted as normal or pre-diabetes may be different according to the biggest health organizations. For example, according to American Diabetes Association (ADA), acceptable normal fasting plasma glucose should range 5 to 7.2 mmol/L (90-130 mg/dL), where the ranges 5.6 mmol/L (100 mg/dL) to 6.9 mmol/L (125 mg/dL) indicate pre-diabetes condition, also called impaired fasting glucose At the same time, according to The World Health Organization (WHO) , fasting plasma glucose level below 6 mmol/L (90-130 mg/dL) are normal and from 6.1 mmol/l (110 mg/dL) to 6.9 mmol/l (125 mg/dL) indicate pre-diabetes condition. The ranges recommended by WHO and ADA have been criticized my many doctors as dangerous targets that stimulate the development of diabetes in the course of time.The criticism is based on the fact that destructive pathophysiologic changes in your body resulting in the death of insulin producing cells start to occur about 10 years before your blood sugar goes beyond normal concentration , so by the time the diagnose is confirmed, the condition is too much progressed. That’s why is the past decade there is a tendency to recommend patients to keep their fasting blood sugar levels below 90 and even 80 mg/dl.
Normal Fasting Blood Sugar Levels for Different Age and Gender Groups
Normal fasting blood sugar levels for women are the same as for men, as well as for pregnant women, although in the latter category tests frequently show somewhat elevated levels because of increased food intake and metabolism changes that take place during pregnancy.
Normal normal fasting blood sugar level for little children slightly differ from those for adults. As the child grows, normal glucose ranges go down. For children under 5 it’s 5.6 mmol/L (100 mg/dL), for the age 5-11 it’s around 70mg/dL, for ages 12 and older it’s 70-80 mg/dL.
While high blood sugar 2 hours after eating may be pointing to the need to correct your diet or just to a heart meal you recently had, high fasting blood sugar may be a sign of diabetes 2 or pre-diabetes condition.
