The body cells require energy for their functioning. When you eat food, mainly the carbohydrates are converted into glucose which travels through the bloodstream and it reaches the cells who take it as per their requirement. Insulin is a hormone produced by the pancreas that regulates the amount of glucose in the blood. It ensures that blood glucose normal levels are maintained for the smooth functioning of the body system. Anything higher of lower than the normal levels may lead to some diseases and complications which can have adverse effects on the body.
Blood glucose Normal levels
Blood glucose normal levels would be that concentration of glucose in the blood which is sufficient to keep the functions of the body healthy. For you to be able to keep glucose levels under control you need to know what would be the blood glucose normal levels. An overall normal range is 70mg/dL to 150mg/dL.The glucose levels in the body vary throughout the day within this range. The glucose levels in the morning before you have the first meals are lowest. Only after you eat anything do they go up. Even then they should be in the marginal range of 80mg/dL to 150mg/dL (i.e. 3.9 to 8.3mmol/L). The level may temporarily go up to 150mg/dL after dinner.
When you have chronic blood glucose levels below 70mg/dL it is a characteristic of low blood sugar or hypoglycemia. If they are beyond 150mg/dL it is an indicator to hyperglycemia or high blood sugar or diabetes. High blood glucose need not necessarily be diabetes. You should consult the doctors to confirm the results with some tests. Very high level may cause nerve damage, kidney damage etc. The low blood glucose levels may lead to impairment of mental functions and loss of consciousness.
Blood glucose test and their normal ranges
There are different tests that can be undertaken to find out whether you are in the normal blood glucose range or not.
* Fasting blood glucose test: This is a test taken after at least 8 hours of fasting. The normal range for this test is advised at 70 to 100mg/dL. If it is more than 126mg/dL after two consecutive blood tests you may be diagnosed with diabetes.
* Postprandial test: The postprandial test is conducted 2 hours after you eat anything. The normal level should be less than 140mg/dL. The level usually comes down to under 100mg/dL among non diabetics after two hours.
* Random blood glucose test: The random test is taken at any time irrespective of when you have eaten. The normal range for this is levels below 200 mg/dL.
* Oral glucose tolerance test: The oral test helps measure your body’s response to sugar. First fasting blood sugar is checked and a sugary solution is taken. The glucose level is measured after two hours. The normal level for this test too should be less than 140mg/dL. This test is commonly taken for pregnant women to check if they have gestational diabetes.
Blood glucose levels may also go high or low in newborns as well as teens. Juvenile diabetes affects children. Parents should consult the doctor about the normal blood glucose levels for their children. Awareness of the blood glucose normal levels helps maintain a balance of what you eat, drink and exercise to be able to lead a healthy life.
