Masked anemia and hematocrit elevation under sodium glucose transporter inhibitors: findings from a large real-world study.

In the current study SGLT2i treatment was associated with significant hematocrit elevation, polycythemia and lower anemia prevalence. Further studies are needed to determine the clinical significance and approach to patients with pretreatment or on treatment polycythemia and the approach to patients with lower-normal hemoglobin levels under SGLT2i treatment.
