With the Continous glucose monitoring (CGM) devices becoming less expensive and having better reliability, any patient with diabetes mellitus can be a candidate for CGM.
CGM should ideally be used for patients with type 1 diabetes and type 2 diabetes on insulin.
It can also be used in patients who have recurrent hypoglycemia (low sugar).
CGM is also very useful for finding out any overnight low sugar (nocturnal hypoglycemia).
