The most important measures you can take at home if you have one or more complications from type 1 diabetes are:

• Keep your blood sugar as close to normal as possible. Keep track of your blood sugar levels with home tests and hemoglobin A1c (A1c) tests at your doctor's office. The A1c test gives you an average of your blood sugar levels over the past 2 or 3 months. The American Diabetes Association recommends a hemoglobin A1c level of less than 7%. Talk to your doctor about what A1c level is best for you.
• Eat a diet that spreads carbohydrate throughout the day.
• Get regular exercise.
• Take your prescribed insulin either by injection or through an insulin pump.
• Do not smoke.

Other measures to care for and protect yourself depend on which complication you have.

Eye disease (diabetic retinopathy)

Call your eye specialist if you notice any changes in your vision. Vision changes may mean that diabetic retinopathy is getting worse. Early detection and treatment can help prevent vision loss.

If you have severe vision loss from diabetic retinopathy, vision aids can help. Your local or state organization for the visually impaired can help you find these aids.

For more information, see the topic Diabetic Retinopathy.

Kidney disease (diabetic nephropathy)

• Take your blood pressure medicines, if prescribed. Your blood pressure should be less than 130/80 mm Hg. Ask your doctor if you need to monitor your blood pressure at home.
• If diabetes has affected your kidneys, limiting your intake of protein may help you preserve kidney function. Talk to your doctor or dietitian about how much protein is best for you.
• Limit salt in your diet because it makes your body retain fluid and can increase your blood pressure.

For more information, see the topic Diabetic Nephropathy.

Heart and large blood vessel disease

Even if you don't have heart and blood vessel problems, you are at risk for them.

• Don't smoke. Smoking increases your risk of a heart attack or stroke, and makes many health problems worse.
• Take your blood pressure medicine, if prescribed.
• Take your cholesterol-lowering medicine, if prescribed.
• Eat a heart-healthy diet.
• Take aspirin daily, if advised by your doctor.
• Limit alcohol. Drink no more than 1 drink a day for women and no more than 2 drinks a day for men. Discuss with your doctor whether you should drink alcohol.

Nerve damage (diabetic neuropathy)

If it affects your ability to feel (peripheral neuropathy):

• Turn your water heater down, and use a bath thermometer or have someone test your bath water to make sure it is not too hot.
• Don't go barefoot. Always wear shoes, even in the house.
• Don't use an electric blanket.
• Arrange your furniture so that the walkways through your house are free of clutter.
