Risk factors
- Having a family member with diabetes
- Being overweight or inactive
- Being over 40 and having other health conditions like high blood pressure

- If you are thinking of starting an intense exercise program
Diagnosis

What to expect at your appointment
If you are told you have diabetes, your healthcare team will talk with you about managing it. They may also suggest an exercise plan that fits your needs.
Treatment
Treatment for diabetes typically involves a healthy lifestyle, including regular exercise, healthy eating, and sometimes medication. Exercise is a key part of helping manage blood sugar.
Self-care at home
- Aim for at least 150 minutes of moderate-intensity activity each week
- Check your blood sugar before, during, and after exercise, if your healthcare team advises
- Carry a fast-acting carbohydrate snack, like fruit juice or glucose tablets, in case you get low blood sugar
Medical treatments
Some people with diabetes need medications to help control their blood sugar. These may be taken as pills or injections. Your healthcare provider will prescribe what is right for you. Never start, stop, or change medication doses without talking to your healthcare team.
Living with this condition
Living with diabetes means keeping an eye on your blood sugar, eating well, and staying active. Exercise can be a part of your daily routine and can make you feel stronger and healthier.
Lifestyle tips
- Build up your exercise amount slowly
- Include both aerobic exercise and strength training
- Wear comfortable shoes and check your feet for blisters or sore spots after exercise
Diet and exercise
Eating a balanced diet and exercising are both important. If you take diabetes medication, your blood sugar can drop during or after exercise. Ask your healthcare team how to adjust your food or medicine to prevent this.
Mental health and emotional wellbeing
Living with diabetes can feel stressful at times. Exercise is a great way to lift your mood and reduce stress. It can help you feel in control of your health.
Prevention
For type 2 diabetes, a healthy lifestyle can often prevent or delay it. For type 1 diabetes, prevention is not currently possible. Exercise still helps both types.
Complications
If left untreated
- If diabetes is not managed well, high blood sugar can damage your heart, eyes, kidneys, and nerves over time
- Not being active can make these risks higher. Exercise helps lower them
Long-term outlook
With regular exercise and good care, many people with diabetes live long, full, active lives. Even small amounts of activity can make a real difference.
