What is the best time to exercise in terms of blood glucose levels?

Many studies have shown that exercise has a positive effect on the blood glucose levels of diabetics, both those who suffer from type 1 and 2. But when is the safest time to exercise? Read on to find out.

Before you do anything, consult your doctor
Everyone’s situation is different, and there is always the risk of things taking a turn for the worst. If you suffer from diabetes and do not currently work out, it’s best to get a qualified opinion before acquiring a gym membership.

It is also important to take into account that for diabetics who use treatments, such as insulin and sulfonylureas, to manage their diabetes, the risk of a spike or drop in blood glucose is much greater than for those who don’t.

It’s important to avoid lows
Since the body uses lots of oxygen and energy during exercise, all diabetics face the risk of blood sugar levels going too low when working out.
In this case, it’s a good idea to establish a routine. Monitor the times in the day when your blood glucose levels are especially low and refrain from working out during these periods. It’s worth mentioning that treatment-users should refrain from working out three hours before bedtime since they might unknowingly experience a low during sleep.

Managing highs

Conversely, once you have the okay-go from your doctor, establish the times of day when your blood glucose levels are at their highest and plan your workout routine accordingly.

Since the most glucose production occurs at night – in order to “prepare” the body for the new day – diabetics who do not use insulin would do well to work out when they rise and shine. For those using treatments, it is best to ask your doctor what to eat before and after morning exercise in order to maintain good blood glucose levels.

Non-insulin users can maintain their glucose levels by working out either pre or post-meal – whichever works best for them. For those who use treatments, it’s usually best to exercise before meals, since they are likely to experience lows during workouts and can make up for this by eating a meal afterward.   

Once you have been assured that exercising is safe for your condition, aim to go to the gym at least 5 times a week for a half-hour of moderate cardiovascular workout. You won’t believe the benefits!
