Insulin works by restoring the patient's ability to store glucose in the liver, muscle and fat cells and release glucose when the body is low in energy. There are different types of insulin that people can administer. They perform the same effect but differ in when the action of insulin will come into effect. The goal of all types of insulin is to manage blood glucose between 4-7mmol/L.
When taking insulin it is important to remember to monitor your blood glucose level before meals and after meals. This method allows you prevent your blood glucose from being too high or too low. It is also important to remember that insulin should be administered in the abdomen where it is readily absorbed.
