If you use more Glucosio Sclavo Diagnostics Syrup than you should
If this occurs outside of direct medical supervision, inform your doctor immediately or go
to the nearest hospital.
Excessive intake by individuals with impaired insulin activity (the hormone that lowers blood glucose levels) causes an increase in blood glucose levels. This increase leads to greater urine production, potentially disrupting the balance of electrolytes in the blood. In patients with diabetes mellitus, accumulation of so-called ketone bodies in the blood and tissues may lead to a toxic condition, possibly resulting in coma—loss of consciousness, motor function, and sensation—and potentially death.
