Blood glucose level
Blood glucose level is the amount of sugar (Glucose) in an individuals' blood stream at any given time[1]. Blood glucose levels can be measured using an appropriate test strip, a blood glucose meter and a small needle to prick the patient's finger with[2].
The normal range for a healthy patient without diabetes is between 4-8 mmol/L however the values for a diabetic patient will fluctuate more due to the problems with their insulin[3].
People with diabetes are more susceptible to hypoglycaemia (which is low blood sugar) and hyperglycaemia (which is high blood glucose) which can cause detrimental effects to the body[4].
Hypoglycemia is caused usually due to an insulin overdose (common in type 1 diabetics), during or after intensive exercise, or during starvation. Hyperglycemia, however, is as a result of either insufficient insulin production (the issue for type 1 diabetics), insulin resistance (which is common in type 2 sufferers), or postprandial due to the consumption of food.
