Medical appointments and vaccines
Schedule and keep yearly physical exams and eye exams. Your health care provider will tell you how often you need medical visits depending on your diabetes management plan. Keep all follow-up visits as told. This is important so possible problems can be identified early and complications can be avoided or treated.
- Every visit with your health care provider should include measuring your:

Blood glucose control.
- Your A1C (hemoglobin A1C) level should be checked:
At least 2 times a year, if you are meeting your treatment goals.
4 times a year, if you are not meeting treatment goals or if your treatment goals have changed.
Your blood lipids (lipid profile) should be checked yearly. You should also be checked yearly for protein in your urine (urine microalbumin).
If you have type 1 diabetes, get an eye exam 3–5 years after you are diagnosed, and then once a year after your first exam.
If you have type 2 diabetes, get an eye exam as soon as you are diagnosed, and then once a year after your first exam.
It is also important to keep your vaccines current. It is recommended that you receive:
A flu (influenza) vaccine every year.
A pneumonia (pneumococcal) vaccine and a hepatitis B vaccine. If you are age 65 or older, you may get the pneumonia vaccine as a series of two separate shots.
Ask your health care provider which other vaccines may be recommended.
Lifestyle
- Do not use any products that contain nicotine or tobacco, such as cigarettes, e-cigarettes, and chewing tobacco. If you need help quitting, ask your health care provider. By avoiding nicotine and tobacco:
You will lower your risk for heart attack, stroke, nerve disease, and kidney disease.
Your cholesterol and blood pressure may improve.
Your blood circulation will improve.
- If you drink alcohol:
- Limit how much you use to:
Be aware of how much alcohol is in your drink. In the U.S., one drink equals one 12 oz bottle of beer (355 mL), one 5 oz glass of wine (148 mL), or one 11⁄2 oz glass of hard liquor (44 mL).
Taking care of your feet

Diabetes may cause you to have poor blood circulation to your legs and feet. Because of this, taking care of your feet is very important. Diabetes can cause:
The skin on the feet to get thinner, break more easily, and heal more slowly.
Nerve damage in your legs and feet, which results in decreased feeling. You may not notice minor injuries that could lead to serious problems.
To avoid foot problems:
Check your skin and feet every day for cuts, bruises, redness, blisters, or sores.
- Schedule a foot exam with your health care provider once every year. This exam includes:
Make sure that your health care provider performs a visual foot exam at every medical visit.
Taking care of your teeth
People with poorly controlled diabetes are more likely to have gum (
periodontal) disease. Diabetes can make periodontal diseases harder to control. If not treated, periodontal diseases can lead to tooth loss. To prevent this:
Brush your teeth twice a day.
Floss at least once a day.
Visit your dentist 2 times a year.
Managing stress
Living with diabetes can be stressful. When you are experiencing stress, your blood glucose may be affected in two ways:
Be aware of your stress level and make changes to help you manage challenging situations. To lower your stress levels:
Consider joining a support group.
Do planned relaxation or meditation.
Do a hobby that you enjoy.
Maintain healthy relationships.
Exercise regularly.
Work with your health care provider or a mental health professional.
