What are normal blood glucose levels is a concern for those who might have a blood sugar issue or have been diagnosed with Pre-Diabetes or Type 2 Diabetes. Hopefully, you are lucky enough to have your blood sugar levels under control. If you or someone you know is having problems in this area, read on. We will explore what normal blood sugar levels are.

What is glucose? Glucose is a form of sugar that travels through the human blood stream. It usually enters your body in the form of foods high in carbohydrates. You can regulate glucose levels through the body's use of insulin and glucagon hormones which are produced by the pancreas. The problem arises if the pancreas is unable to generate the proper amount of glucose to keep your body in check.

Normal blood glucose levels typically register between 70 and 150 mg. The level in someone's body will change during the day and is affected by many factors including what time of day it is as well as what your most recent meal was (or was not). There is danger associated with levels either below or above the range. If your level is below 70, you most likely have a condition called hypoglycemia or more commonly called low blood sugar. Other symptoms of hypoglycemia include lack of energy, focus and irritability. You can even lose consciousness if your glucose is too low.

If the level of sugar in your blood is over 150 mg, then you are considered to be hyperglycemic, also more commonly known as having high blood sugar. If you have persistent high sugar, then you are at risk for diabetes which can result in serious organ damage to your eyes, kidneys and other organs. If you do not have normal blood glucose levels, you should take all necessary steps to reverse the condition. If you have a lifestyle that includes poor habits - including nutrition and exercise practices and decisions that have an adverse impact on your health, now is the time to change your habits and bring your blood sugar under control.

There are a variety of tests available to check for glucose levels.

1) The "fasting blood sugar" test evaluates glucose levels after a fast - typically 8 hours long. This is why most people take this test the first thing in the morning (where their blood sugar would not be impacted by eating, drinking). This is a test that most pregnant women take as well as anyone that a doctor considers at risk for diabetes. If the test results for the blood fall between 70 and 99, the patient is considered to be at a normal range.

2) The "2 hour postprandial" blood glucose test evaluates sugar levels exactly two hours after eating. If the results for this blood test are between 70 and 99, the patient is considered to have normal glucose levels.

3) Random blood glucose testing tests sugar levels all through the entire day - regardless of food consumption, activity, exercise or sleep. For this test, the blood glucose result level should fall between 70 and 135.

4) The glucose tolerance test is performed where the patient drinks a liquid that is mostly made up of glucose. The purpose of the test is to see the blood's reaction immediately after a high amount of sugar is consumed and then released into the blood.

Note that every lab performs their blood glucose tests using their own protocols and methods. If you have an issue with erratic blood sugar levels, you might want to consider changing the lab that performs the testing to see if your glucose levels differ at all.
