Vitamin B12 plays a number of essential roles in the body and these roles are responsible for physical and mental processes. Take its role of supporting the nervous system. The nervous system transmits signals between the brain and the rest of the body, including internal organs.
Constant fatigue is one of the main symptoms of vitamin B12 deficiency, because when this vitamin is low, the body has fewer red blood cells.
The main job of these red blood cells is to carry oxygen from the lungs to other parts of the body.
A lack of red blood cells results in fatigue.
This is why no matter how much sleep you get, if there are not enough of these cells in your body, you will always be spent the day exhausted.

Feeling unusually tired or weak is one of the most common warning signs of the disease, explains the medical website Healthline.
If you are deficient in vitamin B12, your body may have trouble making new red blood cells.
Red blood cells are essential for providing oxygen in the body.
Without enough oxygen in your cells, you can start to feel generally tired or exhausted.

A lack of vitamin B12 can also lead to decreased production of red blood cells and nerve damage.
If the condition is left untreated for a long time, it could put a person at risk for heart problems.
To avoid complications, it’s important to recognize all of the symptoms of a vitamin B12 deficiency, and one symptom to be wary of is a change in breathing.
Experts say shortness of breath, even after a little exercise, can be a sign of the disease.
According to a case report from the Massachusetts General Hospital affiliated with Harvard and published in the New England Journal of Medicine, a 62-year-old man who lacked vitamin B12 gradually became short of breath.
Shortness of breath can occur when the body lacks red blood cells because it needs them to provide enough oxygen to the body’s cells.
Thyroid Patient Advocacy explains that shortness of breath can occur without chest pain and adds that it can occur when walking just a few feet away.
A blood test is usually ordered to check for a deficiency in vitamin B12, which can also measure the size of red blood cells in the body.
This factor is important because vitamin B12 helps create healthy shaped red blood cells.
Insufficient amounts of the vitamin in the body can lead to unusually large red blood cells.
However, a blood test has its limitations – it can measure the amount of vitamin B12 in the body but cannot determine whether the body is able to use it.
