Effect Of Low Blood Sugar Or Hypoglycemia On Brain Power

0 Flares 0 Flares ×

Brain PowerLow blood sugar, or hypoglycemia, is an often overlooked but significant metabolic culprit in poor brain function.

It can cause a wide range of mental symptoms, including lack of concentration, short-term memory loss, mood swings, physical and mental exhaustion, mental fatigue, mental fogginess, depression, and the inability to learn or comprehend new information.


Because of the sugary diets we eat today, Hypoglycemia is epidemic. Your brain needs glucose to form the energy that fuels its processes. It gets glucose from the food you eat – mainly carbohydrates, which the digestion process breaks down into sugar.

Researchers have found that too little sugar in the form of glucose hinders memory and learning. But you should know that too much sugar does the same thing before you reach for that candy bar.

Hypoglycemia is one of the most undiagnosed conditions in America. Many people who suffer from it are totally unaware that they have this trouble, and even their doctors confuse their symptoms with those of other conditions.

Eating too much sugar and other simple carbohydrates is not a good idea for your overall health, but it is particularly bad for memory.

Sugar Overload

Hypoglycemia or “insulin resistance,” can be caused with sugar overload in which your cells do not recognize insulin and thus sugar cannot enter them. According to the Merck Manual of Medical Information, prolonged hypoglycemia can permanently damage your brain cells.

It is significant to have the right kind of fuel available to promote optimum brain functioning because the brain runs on energy derived mostly from carbohydrates.

A healthy program will help you substitute simple carbohydrates with healthy complex carbohydrates, such fruits, as vegetables, and whole grains, which can bring about remarkable enhancement in your thinking and overall health.

An Example

One of my friends, Mandy, was a patient that went to her doctor with a host of health problems, but what worried her most was that she had been fainting regularly, and, although she had been mentally sharp all her life, was now “losing it.” She had been to many specialists and none of them could explain these symptoms.

She found out she was addicted to sugar and often would have a piece of cake or a candy bar for breakfast. Her blood sugar would then roller coaster all day.

She not only did her cognition improve, but, much to the surprise of her physician, her fainting problem completely vanished, when she switched her breakfast to oatmeal with a small amount of tofu or other protein food.

    Thanks for the usual very informative and educational post. I wish more people will visit your blog to benefit from the health and no-nonsense articles you regularly post.

    Being diabetic (type 2), I am very much wary about my sugar intake. This is exacerbated by my inability to have a regular blood sugar count exam. I usually depend on my own body messages to monitor my own blood sugar level condition. I do take my regular maintenance medicines on diabetes and hypertension though.

    I really appreciate your article because it openned my eyes to the other effect of my disease, and that is, hypoglycemia. I’m having my own bouts with short term memory lapses which could be very embarassing at times. Maybe, that too is an effect of hypoglycemia. I do not know.

    Thanks again for the wonderful post. Keep up with them. They are a very valuable source of healthful information.

    God bless you more for your noble endeavor to reach out to people.
