Diabetic hyperosmolar (hi-pur-oz-MOE-lur) syndrome is a serious condition that develops when your blood sugar reaches a very high level. When your blood sugar gets to this level, your blood becomes thick and syrupy, causing diabetic hyperosmolar syndrome. Excess sugar passes from your blood into your urine, triggering a filtering process that draws tremendous amounts of fluid from your body.
Diabetic hyperosmolar syndrome usually affects people with type 2 diabetes, and may develop in people who haven't yet been diagnosed with diabetes.
Left untreated, diabetic hyperosmolar syndrome can lead to life-threatening dehydration. Prompt medical care is essential.
