Podsumowanie W leczeniu cukrzycy typu przez prawie sto lat podstawowym lekiem jest insulina Leczenie to uratowało życie milionów ludzi, ale nie jest doskonałe Wciąż poszukuje się rozwiązań, które umożliwią uzyskanie prawidłowych stężeń cukru bez niedocukrzeń Jednym z takich rozwiązań mogą być flozyny 33
