CGMs beat Dogs for Sensing Lows

By Miriam E. Tucker ,


“Diabetes alert dogs” are specially trained to alert owners to dangerous low blood glucose levels, but how do their skills stack up against a continuous glucose monitor (CGM)? In a study, eight diabetes dog owners with type 1 diabetes wore CGMs for one week each. The CGM alerted the owners that their blood glucose levels were low about 22 minutes sooner than the dogs did. And 88 percent of the time the dogs alerted, the owner did not have low blood glucose. Researchers aren’t sure whether the dogs are smelling hormonal changes associated with low glucose or detecting changes in their owner’s behavior. Either way, when it comes to safety, a CGM appears to be a better best friend.
