Learning to eat well is an important part of managing your diabetes

Many people find sticking to a healthy diet tricky, even without diabetes. For people with diabetes, a nutritious diet means paying very careful attention to things like serving size, carbohydrates, and mealtimes.

The importance of staying active

Staying active can be an important part of your daily routine to keep your blood sugar within your target range. When you are active, your cells become more sensitive to insulin so the insulin can work more efficiently. Exercising consistently can lower blood sugar and improve your A1C.

Learn why exercise is important for patients with diabetes

Exercise doesn’t have to be overwhelming. Activities like walking the dog, cleaning the house, and washing the car can be part of your exercise routine. How you choose to exercise is less important than finding a way to stay active regularly.

For example, you could:

For more support, talk with your health care provider, who can recommend good ways to stay active on a daily basis.

Check in before you start

In addition to helping you make decisions about your exercise routine, your health care provider can talk to you about the diabetes medicines and over-the-counter medications you take. Depending on your level of physical activity, you may need to change from one medicine to another or to adjust the amount you take.

Physical activity and low blood sugar

Sometimes exercise can cause low blood sugar, also called hypoglycemia. It is a good idea to bring a snack or glucose tablets in case your blood sugar gets too low while being active.

Speak to your doctor about testing your blood sugar level to see how the physical activity affected your levels. As always, speak to your doctor if you’re concerned about low blood sugar.

Consider working with a diabetes educator

If you need more support than your doctor can provide, certified diabetes educators (CDEs) also can help you learn the ways of a diabetes-friendly lifestyle.

These educators can be nurses, dieticians, pharmacists, podiatrists, or other doctors. They can help you plan ways to fit your diabetes care into your life.

To locate a diabetes educator near you, visit the American Association of Diabetes Educators (AADE) website and use their Find a Diabetes Educator tool.
