When faced with diabetes, we first think about diet and medications. We sometimes forget one of the most effective levers: physical activity. It acts directly on the mechanisms of the disease and improves blood sugar control. Done well, it is a true ally, in both prevention and treatment.
1. How movement affects blood sugar
During exercise, the muscles consume glucose directly, without the need for insulin: blood sugar levels drop, and this effect persists for several hours. Longer term, regular exercise improves insulin sensitivity, reduces abdominal fat and inflammation.
2. What types of activity?
| Type | Main benefit |
|---|---|
| Endurance (walking, cycling, swimming) | Immediate drop in blood sugar |
| Muscle strengthening | More muscle = better sugar management |
| Combination of the two | Optimal long-term effect |
| Active breaks | Limit peaks after meal |
The combination of endurance and muscle strengthening activities gives the best results. Even short walks after meals help limit blood sugar spikes.
3. Move safely when you are diabetic
Some precautions are necessary, especially during treatment: monitor your blood sugar levels before and after exercise, prevent the risk of hypoglycemia (have enough to replenish your blood sugar), hydrate well and take care of your feet. Medical advice is useful before resuming intense activity.
- Monitor your blood sugar around exercise
- Have something to replenish your blood sugar in the event of hypoglycemia
- Choose your shoes carefully and watch your feet
4. Start and stick over time
The important thing is to start gradually and choose an activity that you enjoy. Aiming for around 150 minutes per week, spread over several days, is a good goal. Regularity takes precedence over intensity.
Combined with a balanced diet, physical activity forms the basis of the management of type 2 diabetes, in addition to medical monitoring.
💡 tips to remember
- During exercise, the muscles consume glucose without insulin: blood sugar drops and the effect lasts for several hours.
- Regular exercise improves insulin sensitivity and reduces abdominal fat: it is a full-fledged treatment for type 2 diabetes.
- The endurance + combination muscle strengthening gives the best results; walks after meals limit peaks.
- Under treatment, I monitor my blood sugar levels around exercise, I keep something to rehydrate me and I take care of my feet.
- I start gradually and aim for around 150 minutes per week: regularity takes precedence over intensity.
