How do sugar levels drop with exercise?

The body receives most of its energy from a special source, sugar, better known as glucose, which comes from carbohydrates in food. The body's way of regulating these sugar levels is with the help of a hormone, insulin, which allows the transport of glucose out of the bloodstream and into the cells.

In this way, when you exercise, your body reduces its sugar levels because it increases its sensitivity to insulin and its use, which allows your muscles to obtain more glucose. Also, when training, the cells are able to absorb more glucose, which ultimately lowers blood sugar.

On the other hand, physical activity depletes the glycogen stores in the body and it can take up to 24 hours to recover all that energy, depending on the intensity of the training. This means that although blood sugar levels do not drop immediately, there is a risk of hypoglycemia in people with diabetes for 24 hours after an exercise session.

Fortunately, those who do not have diabetes have no chance of hypoglycemia, although symptoms of low blood sugar may be visible.

Exercising with diabetes

If you live with diabetes, you know that your body cannot produce enough insulin or use it in the correct way, causing your sugar levels to rise without much difficulty. Therefore, those with this condition usually take special medications to regulate sugar levels , the bad thing is that some of them can make the sugar drop too low during or after training .

Some medications, such as SGLT2 inhibitors, do not affect sugar levels during exercise, but others such as insulin or sulfonylureas can lead to hypoglycemia.

The best way to prevent these problems is to check your levels just before you start training and immediately after you finish. In the event that these are less than 100 mg / dl before starting, you should eat a small snack or drink fruit juice.
