The energy that our body requires for normal functioning comes from the glucose that exists in the blood stream. When we eat food, the carbohydrates are broken down into sugar. When you consume too much of such food there would be high amount of glucose. To enable the glucose levels to be regulated pancreas produce a hormone called as insulin. Insulin does the very important task of releasing the glucose into the blood stream and making it reach the cell. The cells take it from the blood stream thus reducing glucose levels in the blood. There are certain levels considered safe and these are the ranges for blood glucose normal levels. It is necessary to work towards keeping blood glucose normal.
Normal glucose blood levels
The normal range for non diabetics should within 70mg/dL and 110mg/dL or 3.8 to 6.1mmol/L. The fasting blood glucose level is usually less than 6.1mmol/L. The glucose level rises temporarily after meals but comes back to normal levels in about two to three hours. The normal levels recommended for diabetics and non diabetics may be different to a certain extent. Doctors usually allow diabetics a bit higher levels. The glucose levels for diabetics are more to do with better control on diabetes than achieving non diabetic levels. Fasting glucose among the diabetics should be preferably less than 7mmol/L. 2 hours after eating they are recommended at less than 9mmol/L. Inability to control glucose levels within this range may lead to complications of diabetes like eye and kidney disease, nerve damage and heart disease. Glucose levels should preferably be less than 5 before meals and less than 6 after meals. However, this may not be entirely possible with the present medication and there is a possibility of hypoglycemia.
Normal glucose blood levels for various tests
There are several tests that can be taken to find out the blood glucose levels. Each test has its own blood glucose normal level. For fasting blood sugar test is should be within 3.9mmol/L to 5.6 or a maybe a little bit higher. For the random blood sugar test done irrespective of meal timings normal blood sugar level should be less than 11.1mmol/L. The oral glucose tolerance test that measures the response of body to sugar the range is expected to be less than 11.1mmol/L. This test is often prescribed during pregnancy. There is another test the glycated hemoglobin – A1C test which measures average blood sugar over the past three months. For non diabetics it must be about 4 to 6 percent and for diabetics at levels lower than 7 percent. Among the pregnant women it should be lower than 6 percent.
To keep blood glucose normal a healthy diet, regular exercises and supporting medication if required are crucial. If you go beyond the normal blood glucose levels you are at a risk of hyperglycemia or high blood glucose, hypoglycemia or low blood glucose, diabetes. It these conditions are left untreated it may lead to other complications like kidney damage, nerve damage, vision problem, fatigue, giddiness, brain damage etc. You should consult your doctor to know blood glucose normal levels that you have to maintain for a healthy life.
