Take Control of Your Diabetes
It is important to keep your blood sugar, blood pressure, and cholesterol in a healthy range. You should learn these basic steps for managing diabetes and staying as healthy as possible. Steps may include:
- A healthy diet
You may need to check your blood sugar daily or more often. Your health care provider will also help you by ordering blood tests and other tests. All these may help you keep complications of diabetes away.
You will need to check your blood sugar level at home.
- You will use a special device called a glucose meter to test your blood sugar. Your provider will let you know if you need to check it every day and how many times each day.
- Your provider will also tell you what blood sugar numbers you are trying to achieve. This is called managing your blood sugar. These goals will be set for different times during the day.
To prevent heart disease and stroke, you may be asked to take medicine and change your diet and activity:
- Your provider may ask you to take a medicine called an ACE inhibitor or a different medicine called an ARB, for high blood pressure or kidney problems.
- Your provider may ask you to take a medicine called a statin to keep your cholesterol down.
- Your provider may ask you to take aspirin to prevent heart attacks. Ask your provider if aspirin is right for you.
- Regular exercise is good for people with diabetes. Talk to your provider first about what exercises are best for you and how much exercise you should do every day.
- DO NOT smoke. Smoking makes diabetes complications worse. If you do smoke, work with your provider to find a way to quit.
To keep your feet healthy, you should:
- Check and care for your feet every day.
- Get a foot exam by your provider at least every 6 to 12 months and learn whether you have nerve damage.
