Those with diabetes mellitus, both type 1 and type 2, suffer from a lack of or a reduced function of insulin, the hormone that controls blood glucose levels. Elevated blood glucose levels (hyperglycemia) over time can damage organs and tissues of the body resulting in complications of diabetes. On the other hand, hypoglycemia, or the excessive lowering of blood glucose values as a result of the excessive administration of insulin, prolonged physical activity, or a late or inadequate meal, is the other dangerous risk facing diabetics.

Controlling blood glucose levels, in order to keep them in the normal range, is therefore the main objective of those suffering from diabetes. To do this, diabetics must learn to manage the disease, together with the help of a medical team, in order to understand the specific nature of their particular illness and assume a leading role in their overall care.

Knowing that the opportunity to lead a normal life depends on those values can be a strong motivation and an incentive to seek out the devices that have been designed to meet needs that are very specific and, at the same time, so crucial, in terms of quality of life.

In fact, even if all of the devices created to support those with diabetes are useful in therapy (lancet, test strips, gauges, etc..), and today various models for each of these devices are available, this does not mean that all are suited for everyone: each diabetic must find the system most suited to their lifestyle and their choices with respect to the disease (e.g.. communicating it to others or not). Fortunately, today there is ample choice and research has provided us with solutions that tend to concentrate multiple functions, sampling, reading, data download, etc., in a single device, reducing waste disposal operations, and increasing discretion and freedom of use.
In light of the clear correlation between self-testing and glucose compensation, making daily blood glucose testing easier and more discreet, and faster and simpler through the integration of multiple devices, is certainly an important factor supporting and motivating those who are learning the basic principles of self-management of a chronic illness as well as those who have been managing these operations for years as best they can.  This is true for people with type 1 and type 2 diabetes, treated with insulin, oral antidiabetics or diet, as well as - according to the suggestions of the American medical and scientific community - those who have not yet developed real diabetes, but who suffer from postprandial hyperglycemic peaks.
