Preparing for a Fasting Blood Sugar Test

different types of medicine


Before performing a blood sugar level test on the patient, a doctor may advise them to fast for at least eight hours leading up to the test. It means that they shouldn’t eat or drink anything, except for water, during that period. This process is called the fasting plasma glucose test or FPG. A simpler term for this is the fasting blood sugar test. It allows the patient to get accurate results and reveals how their insulin is functioning.

If you plan on getting FPG, it’s important for you to prepare for this appointment, according to a specialist for diabetes in Illinois. For instance, if you’re used to drinking coffee daily for your pick-me-up, you’ll want to skip it before your test. Caffeine can interfere with the results; thus, your doctor may ask you to repeat the test if this happens.

You also need to inform your doctor about the medications and supplements that you’re taking before the fasting blood sugar test. This way, your doctor can advise you on what to do since certain drugs or supplements may cause a false positive test.

Getting accurate results of your blood sugar test is crucial because it allows your doctor to determine your treatment plan in case you have diabetes.
