The fluctuation in blood glucose levels from very high to low may causes severe damage to the body system. The increase in the sugar levels may be the result of various factors and if left untreated may lead to complications. However, if you are aware of what should be the normal blood glucose levels you can ensure appropriate diet, exercises and medication to prevent future complications. There is a subtle difference in the normal blood glucose levels in diabetics and non diabetics. For diabetics it may be a little higher as it has often been seen that the safe levels may be affected by health conditions, state of diabetes, use of the diabetes medicines, insulin, diet and exercises. When the levels go low it may lead to hypoglycemia, thus the safe levels are relevant.
Normal blood glucose levels
The normal range of blood glucose accepted by all is around 80mg/dL before meals. Generally the levels increase after 1 to 2 hours after meals. The normal range should be less than 160mg/dL or 8.8mmol/L. These figures are for blood samples taken from veins also called as whole-blood sample. Sample drawn from the fingertips is called plasma blood sample and the readings for it should preferably be 70mg/dL to 130mg/dL or 7.2mmol/L before meals and less than 180mg/dL or 10mmol/L, 1 to 2 hours after meals.
You need to be aware of the normal blood glucose levels that are result of the glycated hemoglobin or A1C (HbA1c) test. It is a measure of percentage of glucose stuck to hemoglobin. This enables you to find how well you have been able to control diabetes. The normal level for adults should be 7%. In children less than 6 years of age it is recommended between 7.5% and 8.5%. In children aged 6 to 12 years the level should be at 8%. For teens aged 13 to 19 years it should be less than 7.5%. A low level around the given ranges means you have been able to control glucose levels.
During pregnancy the doctor may advice certain levels. It should preferably be 70mg/dL to 100mg/dL before meals using a whole blood sample and 80mg/dL to 110mg/dL using a plasma blood sample. Two hours after the meal it is recommended to be less than 140 using a whole blood sample and 155mg/dL using a plasma blood sample. All these figures quoted are as recommended by ADA.
Dietary Pattern and Exercises to maintain normal blood glucose levels
Blood glucose levels are affected not just by what you eat but also because of exercises or the lack of it, medication and quality of food intake. It is very important for all to have healthy diet. Those with higher levels should include a balanced diet with lesser carbohydrates and sweet foods. Fresh fruits and vegetables, whole grain breads are of great help. A reduction in carbonated sodas is advisable. Physical exercises like brisk walking, swimming or any other sport that you like helps as it consumes the glucose in the form of energy. Learn time management so that you are not stressed out which may cause the shooting up of glucose levels in your blood.
Ensure that you seek advice from your doctor on the normal blood glucose levels whether you are diabetic or not. Similarly take appropriate medication as well as have a healthy diet and exercise regularly to keep it within the acceptable range.
