7 Facts About The Fasting Blood Sugar Test

There are a number of things that everyone should know before doing a fasting blood sugar test, all of which are included in this list of 7 fasting blood sugar test facts.

  1. In most cases the individual should begin the fasting period 8 hours prior to taking the fasting blood sugar test. This time can vary however depending on the test being used, so this information should be confirmed before hand. Typically, instructions will be provided by the doctor or lab performing the test but if there is any doubt the exact required fasting time should be confirmed with them.
  2. A blood sugar level chart is a useful resource, which can be used both after a period of fasting and a period of eating and can help to determine the effects that certain foods have on the individual’s blood sugar levels. This information will provide a good basis for prescribing treatment.
  3. Follow the instruction provided for fasting time very carefully and always fast for the minimum amount of time specified. Fasting blood sugar test result will be inaccurate if the individual even eats a small snack when they should be fasting and this can lead to a misdiagnosis and therefore the wrong treatment being prescribed.
  4. The individual and their doctor should also know normal blood sugar levels, so that they can be compared to their fasting blood sugar levels. This may also be a good opportunity to have a glucose tolerance test, which will reveal how well the body is able to handle glucose. The doctor may also take this time to make their patient aware of some of the symptoms associated with high blood sugar, so that they are easily recognizable if they were to arise in the future.
  5. Plain water is allowed during the fasting period before the fasting blood sugar test is performed but it must be free of sugar and flavoring. In fact it is important to keep drinking water through this time in order to prevent your body from becoming dehydrated.
  6. One of the major consequences of blood sugar becoming too high is the onset of diabetes. Depending on the severity of the condition, this can lead to the use of insulin shots to control the symptoms. An individual is considered to be diabetic when their fasting blood sugar levels reaches 125 mg/dL or higher.
  7. Results of a fasting blood sugar test are considered normal at 100 mg/dL. Results that are any higher than this suggests that there is an underlying cause that could lead to diabetes. Results of a fasting blood sugar tests that are any lower than 70 mg/dL suggests that the individual is suffering from a condition called hypoglycemia. This is another serous illness, which can lead to further complications and problems.
