Why brain fog may be a sign of blood sugar instability

Who would have thought that brain fog, a condition in which we feel mentally slow, confused, unfocused, without realizing, could be directly linked to our insulin and blood sugar levels? Well, researchers say yes! One of the most overlooked causes of brain fog is blood sugar instability. Since the brain is dependent upon a steady supply of glucose for energy, fluctuations in blood sugar levels, whether it is too high or too low, or constantly changing, can significantly impair cognitive function. There might be a shortcut now! Understanding the complex relationship between our brain and blood sugar might be the key to improving our mental clarity and overall well-being.

What is brain fog

Brain fog, or mental fatigue, is a word used to define symptoms that can hinder your ability to think. One may feel disoriented, confused, and lack focus in daily activities. It is not a medical condition in itself, but is known to stem from other medical conditions.

What are the common causes of brain fog

Hormonal changes

During pregnancy or menopause, women go through various changes in the levels of the hormones estrogen and progesterone. This change can affect memory and lead to short-term cognitive disabilities, leading to forgetfulness, low concentration levels, and fuzzy thoughts.

Stress and lack of sleep

Excessive stress and lack of quality sleep may lead to high blood pressure, a weak immune system, and even depression. When our brain exhausts itself, it faces difficulty functioning optimally, which can lead to cloudy thoughts, poor retention.

Medications and certain diseases

Chronic diseases such as Anemia, depression, diabetes, and even autoimmune diseases such as Lupus, arthritis, and multiple sclerosis can lead to brain fog.

The link between brain fog and blood sugar instability

If there is any organ in our body that is the most energy-hungry is our brain. It uses up about half of the body’s sugar energy. When our blood sugar levels are too high or even too low, the brain cannot function properly, leading to cognitive issues such as mood swings, confusion and poor memory, which is scientifically called brain fog.

High blood sugar (Hyperglycemia)

Over time, according to the CDC, high blood sugar levels damage blood vessels in the brain, leading to reduced oxygen flow to the brain cells, which in turn leads to memory and thinking problems and eventually vascular dementia. If the brain suffers from chronic stress, it can contribute to mental fog, cognitive decline, and even sluggish thinking.

How does low blood sugar contribute to brain fog?

When our blood pressure drops below 70 mg/dL, the brain does not get enough oxygen. It creates this feeling of dizziness, confusion, and trouble speaking. In worst-case scenarios, it can cause seizures or even come.
