Physical activity

Physical activity (exercise) is one of four key components -- along with nutrition, medication and blood glucose monitoring -- of daily diabetes care. For people with diabetes, being physically active is especially important because it boosts fitness levels while reducing blood glucose and blood pressure levels.
It doesn't have to be a marathon to make a difference. You can spend hours at the gym, but just as important are those hours of gardening, taking the stairs instead of the elevator, and strolling around the block after dinner, that help you keep your diabetes in control. If you learn to make exercise a habit -- a fun habit -- your body will enjoy an amazing number of benefits. Please make sure you consult your doctor or diabetes educator before beginning a new exercise program, especially if you are over 35 or have had diabetes for 10 years or longer.
For people with diabetes, exercise:
Helps your body use insulin more effectively
Can lower blood glucose levels
Strengthens heart and lungs
Reduces body fat and increases muscle
Assists with weight control
Helps you cope with stress
Improves your self-image
Helps reduce risk factors for heart disease
Lowers blood pressure
Exercise Program RemindersBefore beginning any exercise program, consult your doctor, especially if you are over age 35 or have had diabetes for 10 years or longer.
Risks of Exercise
Certain types of exercise may worsen eye, kidney, or nerve problems. If you have any of these problems, get professional advice about exercise.
Blood pressure may rise higher during exercise in people with diabetes than in those without diabetes.
People with diabetes are at increased risk for heart problems. Stop exercising and consult your doctor if you have any of the following symptoms: chest pain, unusual fatigue, dizziness, visual disturbances, or nausea.
Know how to prevent hypoglycemia if you take insulin or diabetes pills.
Avoid exercise if your blood glucose is under 80 mg/dl (4.4 mmol/L) or over 300 mg/dl (16.7 mmol/L) or if it is over 240 mg/dl (13.3 mmol/L) and ketones are present.
Wear your diabetes ID during exercise.
