Diabetic hyperosmolar syndrome

You have type 2 diabetes, and you haven't been following your treatment plan. When you dig out your glucose monitor and test your blood sugar level, you discover that your blood sugar is sky high.

If your blood sugar level tops 600 milligrams per deciliter (mg/dL), or 33 millimoles per liter (mmol/L), the condition is known as diabetic hyperosmolar syndrome. When your blood sugar gets this high, your blood becomes thick and syrupy. The excess sugar passes from your blood into your urine, which triggers a filtering process that draws tremendous amounts of fluid from your body.

Left untreated, diabetic hyperosmolar syndrome can lead to life-threatening dehydration. Prompt medical care is essential.

Diabetic hyperosmolar syndrome may be triggered by:

• Illness
• An underlying infection, such as pneumonia or a urinary tract infection
• Not following your diabetes treatment plan
• Certain medications, such as water pills (diuretics)
• Substance abuse

Sometimes undiagnosed diabetes results in diabetic hyperosmolar syndrome.

Consult your doctor if you experience any signs or symptoms of diabetic hyperosmolar syndrome, including excessive thirst, increased urination, confusion, vision changes or weakness on one side of the body. Seek emergency care if your blood sugar level is 600 mg/dL (33 mmol/L) or higher.

You'll be diagnosed with diabetic hyperosmolar syndrome if your blood sugar level is 600 mg/dL (33 mmol/L) or higher.

To evaluate how well your kidneys are working, the doctor may measure the amount of nitrogen or creatinine (a breakdown product of creatine, an important part of muscle) in your blood. Another blood test known as a hematocrit may be done to measure the proportion of red blood cells and fluid in your blood. The doctor may measure the amount of potassium in your blood as well.

Diabetic hyperosmolar syndrome can lead to convulsions or coma. Kidney damage is possible if the muscle fibers begin to break down. Blockages within the blood vessels may lead to a heart attack. Without prompt treatment, diabetic hyperosmolar syndrome can be fatal.

Emergency treatment can correct diabetic hyperosmolar syndrome within hours. Treatment typically begins with intravenous fluids to restore water to your tissues. You may need potassium, sodium or chlorine supplements to help your cells function correctly. When enough fluid has been replaced, short-acting insulin can help your tissues absorb glucose again. Any underlying infections will be treated as well.
