A frightening sign of vitamin B12 deficiency caused by "inadequate blood flow to the brain"

Vitamin B12 supports many important processes in the body

from assisting in the production of red blood cells to supporting the nervous system, therefore, it is natural that its lack leads to a series of health problems.

Harvard Medical School described vitamin B12 deficiency as "deceptive" and "harmful." This is because symptoms associated with this condition can appear from nowhere, with some particularly frightening signs, such as fainting.

Everyone is afraid of the idea of fainting. Any alarming signs of dizziness or light vertigo in the head may be the first sign that a fainting attack is about to occur.

But how does vitamin B12 deficiency lead to this frightening sign?

Dr. Ioannis Lyakas, Medical Director at Vie Aesthetics, said: 

"Vitamin B12 deficiency can lead to a disorder of the nervous system and circulation. When you lack vitamin B12, you may develop anaemia as a result of reduced DNA production, causing signs of weakness, fatigue and head sickness. "

He added: 

"Anaemia is a condition where the number of blood cells is lower than normal, or you have an abnormally low amount of a substance called hemoglobin in each red blood cell. Fainting attacks due to nerve function loss can occur when there are deficient levels of vitamin B12. "

The American Heart Association explains that fainting is also associated with blood flow to the brain. The organization explains that "insufficient blood flow" to this organ can cause temporary loss of consciousness.

Furthermore, research published in the journal Acta Clinica Croatica also links these symptoms to the lack of B12.

The good news is that all patients with neurological symptoms of vitamin B12 deficiency were able to recover within one month after taking vitamin supplements.

There are a number of alarming signs to note along with fainting, which can indicate that vitamin B12 deficiency is most likely, the actual cause of fainting.

Dr. Lyakas revealed a list of these signs which include:

• Fatigue and fatigue

• Weakness

• Anorexia

• Weight loss

• Numbness and tingling in hands and feet

• Balance problems

• Weak memory

• Mouth soreness or tongue

• Mouth ulcers

• Feeling faint and dizzy
