SLC5A1 and type 1 diabetes mellitus: Future trials might determine whether the beneficial effects of SGLT inhibition on blood pressure [25] and arterial stiffness [32] translate into improved cardiovascular outcomes (still a major cause of increased morbidity and mortality in type 1 diabetes [8]), whether SGLT inhibitors have a reno-protective effect in type 1 diabetes (as in type 2 diabetes [33]) and does dual SGLT1/2 inhibition have additional benefits in those with impaired renal function because of the reduction in gastrointestinal glucose uptake.
