Understand and keep blood glucose levels normal

Glucose which is a type of sugar is the major source of energy for the body of mammals. It is regulated by the hormone called insulin, which is produced by the pancreas and released into the bloodstream when glucose level rises. There are certain ranges which are considered normal blood glucose levels. The glucose levels keep on changing depending upon when you eat and exercise. Keeping blood glucose levels normal is very important for our overall health.

Normal levels

Blood glucose levels are calculated as millimoles per liter of blood. The blood glucose levels that are considered normal are less than 6.1mmol/L when measured after a fast. In general the normal glucose levels would be less than 7.8mmol/L if done 2 hours after a meal. It should come back to 6.1 within 3 hours of eating. Normally the blood glucose levels are lower in the morning and rise only after your first meal. The levels are high in the two hours immediately after meal but temporarily. They come down after maybe 3 hours. The normal levels preferred amongst diabetics and normal people may differ to a certain extent. You may even find your doctors telling you that if you are a diabetic then your levels can be slightly different or higher than what are found among the non diabetics.

Normal blood glucose levels among diabetes

The glucose levels that are considered as controlled diabetes may be a little different than the normal ones given above. Fasting glucose less than 7mmol/L is usually considered as well controlled diabetes. If testing 2 hours after eating, the recommended levels have to be less than 9.

These values are based on glucose levels and they are associated with complications of diabetes like eye and kidney disease. We should aim to achieve much lower glucose values, so as to reduce the risk of heart disease. It should be less than 5 before meals and less than 6 after meals. However, this may not be entirely possible with the present medications as there is a possibility of hypoglycemia.

Depending upon when the tests are conducted the range for normal glucose may vary. For fasting blood sugar test the normal range is within 3.9mmol/L to 5.6 or a little bit higher. If a random blood sugar test is taken irrespective of meal timings a normal blood sugar level should not be higher than 11.1mmol/L. If an oral glucose tolerance test is taken, which measures the response of body to sugar, then again the range is expected to be not more than 11.1mmol/L or slightly higher. The glycated hemoglobin – A1C test which measures average blood sugar over the past few weeks or months helps understand how much you are able to control your diabetes. Though the range may vary depending on the laboratories, for non diabetics it about 4 to 6 percent and for diabetics preferred levels should be lower than 7 percent. Amongst pregnant women it should be lower than 6 percent.

You can keep blood glucose levels normal with proper medication, diet and exercises. If you are unable to keep blood glucose levels normal then you are at a risk of hyperglycemia (high blood glucose), hypoglycemia (low blood glucose), diabetes and other complications like kidney damage, nerve damage, vision problems etc. Consult your doctor about the normal acceptable levels of blood glucose so that you can always stay in control and lead a healthier life.
