However, there is another equally important reason that Vitamin B12 deficiency is linked to fatigue and can only be understood at the cellular level. Let me explain…
There is a specific cell form that is associated with Vitamin B12 deficiency, known as anisocytosis. Anisocytosis is a condition where a person’s red blood cells are of unequal size; some of the red blood cells are abnormally small and some of the red blood cells are abnormally large.
Our red blood cells are designed to be of perfect size so that when they pass through the capillary beds, they simply “squeeze” through. It is this squeezing effect that allows an exchange of oxygen, nutrients and hormones.
However, when our red blood cells are smaller than normal, this squeezing effect does not occur. Instead, they simply slip through without exchanging oxygen and nutrients, as they should.
When our red blood cells are larger than normal, they have to “fold” to pass through. This folding reduces some of their contact with the capillary wall, and again, hinders the transfer of oxygen.
As you can see, the issue of Vitamin B12 deficiency leading to fatigue is two-fold. First, when a person is deficient in Vitamin B12, their red blood cells are incapable of carrying the proper amount of oxygen due to low levels of hemoglobin.
But the issue doesn’t end there. In addition, their red blood cells may be of unequal size (anisocytosis), hindering the cell’s ability to exchange oxygen in the capillary beds (where the exchange should happen).
Oxygen is needed by every cell in our body to live and function properly. Without oxygen our cells cannot function properly and they can even die prematurely. Therefore, it is the low levels of oxygen in the blood that ultimately lead to fatigue. Low oxygen levels can lead to other health conditions, too, such as dizziness, headache and shortness of breath.
If you (or someone you know) suffer from chronic fatigue, you could be deficient in Vitamin B12. Call today to schedule a live blood cell screening to determine if your blood shows a Vitamin B12 deficiency.
