This triggers the pancreas to start producing insulin. When food is eaten, it is broken down into sugar (glucose) and released into your bloodstream. It is a complicated condition and there are many forms. Following consultation with stakeholders, HTW agreed it was appropriate to issue updated Guidance, since there has been a substantial change in the available evidence since the original Guidance was published.ĭiabetes is a long term health condition that affects how your body turns food into energy. HTW Guidance is periodically updated when necessary. HTW originally issued Guidance on FLFGM in November 2018. This means that a ‘snapshot’ as well as a trend in blood glucose can be obtained to guide decision-making. Glucose levels recorded by the sensor are accessed by scanning over the sensor using either a dedicated reader or a mobile phone app. The Freestyle Libre flash glucose monitoring (FLFGM) technology provides an alternative to this by measuring the glucose level in subcutaneous tissue using a disposable sensor applied to the upper arm. The standard means of monitoring blood glucose involves finger-prick testing (self-monitoring of blood glucose, SMBG). Regular blood glucose measurements are essential throughout the day for many people with diabetes, particularly those receiving insulin treatment, to guide treatment and nutrition decisions and to avoid the potentially serious consequences of blood glucose being too low (hypoglycaemia) or too high (hyperglycaemia). Maintaining the blood glucose concentration as close as possible to the normal range is an important objective for successful diabetes care since this helps to minimize short and long term complications.
