Diabetes: Preventing High Blood Sugar Emergencies

How do you prevent high blood sugar emergencies?

Treat infections early

Infections that aren't treated (such as urinary tract infections, pneumonia, and skin infections) can raise your risk for a high blood sugar emergency.

Be prepared

• Know the symptoms of high blood sugar. They include feeling very thirsty, feeling very tired, and urinating more than usual. Post a list of the symptoms in a place where you can see it often, such as on your refrigerator door. Add any symptoms you have noticed that may not be on the list. Make sure other people know the symptoms. Teach them what to do in case of an emergency.
• Check your blood sugar at home often, especially if you are sick or not following your normal routine. If you don't have a blood sugar meter, talk with your doctor about getting one. It is easy to miss the early symptoms, especially if you urinate more than usual but aren't more thirsty. Testing your blood sugar at home will help you know when it is high, even if you don't notice symptoms.
• Teach others (at work and at home) the symptoms of high blood sugar. Teach them to call 911 if you are unconscious or too sick to check your own blood sugar.
• Wear medical identification. Have a medical alert bracelet or other form of medical jewelry with you at all times. This is very important in case you are too sick or injured to speak for yourself. You can find medical identification at a drugstore or on the Internet.
• If you take insulin, test for ketones, especially if your blood sugar is high.
• Make a plan. Usually people who take insulin need to take extra fast-acting insulin when their blood sugar levels are high. Talk with your doctor about how much to take. This depends on your blood sugar level (sliding scale).
• Take your medicines as prescribed. Don't skip diabetes medicine or insulin doses without first talking with your doctor.

Treat high blood sugar early

The best way to prevent high blood sugar emergencies is to treat high blood sugar as soon as you have symptoms or when your blood sugar is well above your target range (for example, 200 mg/dL or higher).

• Follow your doctor's instructions for the steps for dealing with high blood sugar. Post the steps in a handy place at home and work. Make sure other people know what to do if you are unable to treat high blood sugar.
• Keep a record(What is a PDF document?) of high blood sugar levels. Write down your symptoms and how you treated them. And take the record with you when you see your doctor.
• Call your doctor. Let your doctor know if you have high blood sugar problems. Your diabetes medicine may need to be adjusted or changed. If you take insulin, your dose of insulin may need to be increased.

Drink plenty of liquids

If your blood sugar levels are above your target range, drink extra liquids. This helps replace the fluids lost through your urine. Water and sugar-free drinks are best. Avoid caffeinated drinks, alcohol, and soda pop. And avoid other drinks that have a lot of sugar, such as fruit juice.
