"The FreeStyle Libre 2 flash glucose monitoring system is designed to change how people with diabetes measure their glucose levels and ultimately help them achieve better health outcomes. It is a revolutionary product for the UK diabetes community with strong support across patient groups, healthcare professionals and key opinion leaders.
Two clinical trials^i,ii and real‐world evidence from more than 50,000 usersⁱⁱⁱ show that people who use the FreeStyle Libre system scan their glucose levels an average of at least 15 times per day. In real‐world use, higher rates of scanning to self‐monitor glucose were found to be strongly associated with improved glucose measures, including decreased time in hypoglycaemia (low glucose levels) and hyperglycaemia (high glucose levels) and reduced estimated HbA1c.
