When it comes to staying fit, there’s no need for diabetes to hold you back. If you’re managing your condition effectively, exercise has plenty of health benefits, as working your muscles leads to greater glucose uptake, thereby helping towards lower blood glucose levels. However, there are some things to be aware of in order to manage diabetes successfully during exercise.
Types of exercise
The type of sport you choose to do can have a direct impact on your blood glucose levels. For example, endurance activities, such as cycling or long distance running can lower your glucose levels, while high intensity sports like sprinting can initially cause your blood sugar levels to rise, and these will only lower if the session lasts long enough. If you’re unsure about exercising with diabetes, check with your doctor, start slowly and build up your level of activity gradually as you feel more confident.
Before exercise
In order to manage your glucose levels, it’s important to check them regularly. Before starting a workout, asses them and if your levels are a bit low, you may need to eat a snack high in carbohydrates before setting off. As always, you should discuss with your doctor about you exercise plan and the most appropriate treatments according to your specific treatment programme.
During exercise
If you’re planning to exercise for a long period, you may need to carry a carbohydrate-rich snack and remember to keep watching your glucose levels. Checking your levels while exercising doesn’t have to be tricky – technology such as the FreeStyle Libre system (freestylelibre.co.uk) can show you clearly whether your sugar concentrations are rising or falling through a simple sensor you attach to the back of your upper arm.
After
The hours after exercising are key for those with diabetes as often a drop-in adrenaline levels can also cause glucose levels to fall dramatically. To avoid the risk of hypoglycaemia (severe low blood glucose levels), you may need to take less insulin that evening or eat a low GI snack, especially if you often exercise after dinner. Your doctor will be able to provide you with the best advice for you and your specific diabetes treatment plan.
