a hyperosmolar hyperglycemic state (hhs) develops when a person with type 2 diabetes has very high blood sugar—usually 34.0 millimoles per litre (mmol/l) or more. sometimes this condition is the first time a person learns that they have type 2 diabetes.
a hyperosmolar hyperglycemic 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 hyperglycemic state include:
- increased urination for several days.
- dehydration, which develops because the person doesn't drink enough liquids.
- a change in alertness from generalized fatigue to stupor, coma, or seizures. these changes may be mistaken for a stroke or mental illness.
hyperosmolar hyperglycemic state is treated in a hospital with insulin to reduce the blood sugar level and extra fluids through a vein (i.v.) to replace the lost fluids.
the best way to prevent a hyperosmolar hyperglycemic state is to treat high blood sugar levels early and drink enough liquids.
