Blood sugar level is 800 how do doctors get the level down quickly?

HYPERGLYCEMIA : Your elevated blood sugar can be monitored to go down by giving Insulin shots in a hospital setting.

Insulin drip: At a seriously high level of 800?!, you would need emergent treatment. Most meters read hhh (high) over 500. Get emergent care if your level is 800.

Go to ER: They will need to start an Insulin drip (iv). This level of blood sugar is a medical emergency and can kill you. You need to be monitored for dehydration and for potassium..... Go to er now.

IV insulin, fluids: A blood sugar level of 800 is dangerously high and probably be associated with a potentially fatal condition called diabetic ketoacidosis. This metabolic emergency is treated with intravenous insulin, replacing fluids lost by dehydration, and adjusting electrolytes (sodium, potassium). It could take 4-6 hours to safely lower a blood sugar this high.

IV medication: This is an emergent level. If the level is 800, it needs to be brought down. Often it is with an Insulin IV drip. But this that will cause havoc with electrolyte balances if this is a type i dm. Get evaluated and get this under control.
