This is how physical exercise affects blood glucose levels


People with diabetes need to monitor daily blood glucose levels in your body. One of the keys to avoid problems is to take care of your diet, but the physical exercise it also plays a bigger role than we can imagine.

Specifically, the diabetes Type 1 is characterized in that people do not have the ability to make enough insulin through the pancreas. And is that insulin is a fundamental hormone for the absorption of glucose by the body.

Therefore, people with type 1 diabetes also need to constantly monitor their blood glucose levels to prevent further health problems. Not only diet is part of the key habits of people with diabetes.

Sport is also a key factor that can influence blood glucose spikes. Therefore, it is necessary to know the relationship between physical exercise and type 1 diabetes.

How sports influence glucose levels

People with type 1 diabetes must monitor their blood glucose levels almost daily. Normally, this control is carried out after meals, to know how your body reacts to certain foods.

It should be noted that people with diabetes are not prohibited from eating any specific food. However, if it is convenient to limit different types of food, such as those rich in carbohydrates that represent a considerable increase in blood glucose levels.

But it is also important to know that sports and physical exercise constitute a highly beneficial habit for people with diabetes, both type 1 and type 2.

In addition, the practice of physical exercise is positive to such an extent that it can help prevent diabetes during the adolescent period.

However, it is necessary to regulate physical activity. A high intensity level can cause hypoglycaemic episodes (low blood glucose levels) in some people.

Check blood glucose before starting activity

To avoid problems such as hypoglycemia when performing physical activity, it is recommended that people with diabetes monitor their blood glucose levels before, during and after exercise. It is a way of knowing how each organism reacts to sports stimuli.

On some occasions, diabetes experts advise balancing optimal blood glucose levels if necessary before beginning physical exercise. Thus, it is important to take into account different ranges of glycemic values:

1. In case of presenting blood glucose levels below 100 mg / dL, considered low, it is advisable to incorporate a small carbohydrate supplement of 5 to 10g before starting physical activity. In any case, it is not recommended that people with diabetes perform physical activity with blood glucose levels below 90 mg / dL.

2. Optimal blood glucose levels for physical activity are between 100 and 250 mg / dL. However, it must be taken into account that there can be a significant glucose elevation if the intensity of the exercise is high and is carried out in short periods of time.

3. Finally, if the blood glucose before starting the exercise is above 250 mg / dL (hyperglycemia), it is advisable to leave sports practice for another time when blood glucose values ​​are at normal levels.
