Can Your Blood Glucose Levels Affect the Function of Your Brain?

The brain is an organ which is sensitive to the amount of glucose it gets as a fuel.

It doesn’t matter whether people have type 1 diabetes or type 2 diabetes, both low blood sugar and high blood sugar might impact your brain. Understanding the role of sugar in the brain is vital for people who have diabetes.

You should know that the brain consumes a big amount of sugar, therefore maintaining a constant amount in the blood is vital in order to ensure for your brain to function correctly.

The Energy of the Brain

The brain is the most energy demanding and most complex organ in the body. The brain needs twice as much energy in comparison to other organs.

It’s like that since the brain is abundant in nerve cells and neurons. These cells actually expend energy in order to make specialized proteins and enzymes to function.

The initial function of neurons is to produce electrical signals with communications with the other neurons found in the brain. Transmitting and generating these signals actually uses around 10 % of the total energy supply of the body.

Brain Functions

The main role of sugar in the body is to act as fuel for energy. In fact, the brain entirely depends on sugar in order to function normally. The brain functions like memory, thinking, and learning are tied to the sugar levels and how efficiently the brain uses sugar.

The glucose is so important that the memory functions might be improved in older adults who have poor memories. The memory functions might improve only 60 minutes after having a meal rich in carbs.

Study on This Topic

According to one research, the blood sugar levels even at normal range might have a big influence on the brain atrophy when it comes to aging.

Dr. Walsh from CRAHW at ANU, says that even people who don’t have diabetes might have high blood sugar levels and have a negative impact on their health.

Moreover, people who have diabetes might have lower blood sugar levels than expected because of the successful management of exercise, diet, and drugs.

According to Dr. Walsh, all people should adopt healthy lifestyle habits, like healthy and balanced diet and regular exercise. Furthermore, it’s important to avoid sugar and highly processed foods.

The Link Between the Brain and Blood Sugar

The term blood glucose actually refers to the amount of sugar which is found in the blood. The normal level of blood glucose is below 120 mg per deciliter, from 1 or maybe 2 hours after having a meal.

When the blood glucose levels are too high or too low, this is known by the name hyperglycemia and hypoglycemia. Hyperglycemia might occur because of diabetes, where the blood glucose is too high, but the glucose doesn’t get to the brain.

Therefore, the brain might function less efficiently. On the other hand, hypoglycemia might cause loss of energy when it comes to the proper functioning of the brain.

In fact, the low glucose levels are connected to poor cognitive function and attention. Now you are aware of the importance of your blood glucose levels and how they influence your brain.
