The normal range of blood sugar levels means the level of sugar (glucose) in your bloodstream is not too high (hyperglycemia) or too low (hypoglycemia). There are a number of specific situations that can affect your blood glucose level to fluctuate. The main ones are after eating and fasting.
Almost all foods that you eat will be digested, and some that contain sugar will break down to become a simple sugar called glucose. This glucose then can directly go into the bloodstream so the body can convert it to become energy. In other words, glucose is the primary component for the fuel of your body.

When glucose goes into the bloodstream, there is a kind of hormone to regulate the level or volume of glucose in the blood. This hormone is called insulin – it is produced in the pancreas. Your body needs insulin to facilitate the distribution of glucose from the bloodstream to the tissues or cells of the body.
The excess glucose in the blood is usually converted to become glycogen and then stored in the liver. Some also can be stored in fat cells in a form as ‘fat’. Either glycogen or glucose in a form of fat can be a source of energy for your body between meals.
If your insulin doesn’t work properly, the normal mechanism of your glucose metabolism goes awry. In diabetes, this condition is often called as insulin resistance.
FBG, also known as FBS (fasting blood sugar), is a procedure to measure the level of your blood glucose after fasting (when you don’t drink and eat anything for at least eight hours). Normally, the fasting blood sugar in adults is around 100 mg /dL or lower.
But if it is higher than 100 mg /dL, it is considered abnormal. If left untreated, it may rise higher than 130 mg /dL which can be considered as hyperglycemia. Hyperglycemia is commonly found in diabetes, but sometimes it may also occur in non-diabetics.
If you experience any diabetes symptoms, even though if you’re not a diabetic, see a doctor to find help. You may be scared of pre-diabetes diagnosis, but don’t worry! You still have a good chance to reverse and prevent type-2 diabetes if you are diagnosed with pre-diabetes. See also about foods to prevent diabetes onset in here!
Typically, the lowest levels of blood sugar occur at the times just before you get your meals (especially in the morning before breakfast).
In healthy, non-diabetics; the range of blood sugar levels before eating (between meals) is commonly about 70 mg /dL to 80 mg /dL. Depending on the fit status of each individual, sometimes the range of 60-90 mg /dL before meals is still considered normal. What’s more?
