A hyperosmolar state develops when a person with type 2 diabetes has very high blood sugar—usually 600 milligrams per deciliter (mg/dL) or more. Sometimes this condition is the first time a person learns that they have type 2 diabetes.
A hyperosmolar state can develop when a person is very sick and/or dehydrated, such as from the flu, a severe infection, a heart attack, or water pills (diuretics). If the person does not drink enough liquids, they may become confused. Older people are at increased risk for developing a hyperosmolar state.
Symptoms of a hyperosmolar state include:
Hyperosmolar state is treated in a hospital with insulin to reduce the blood sugar level and extra fluids through a vein (IV) to replace the lost fluids.
The best way to prevent a hyperosmolar state is to treat high blood sugar levels early and drink enough liquids.
