Fatigue and Exhaution
One of the most frequent signs of a B12 deficiency are feeling wearied and
tired.
This Vitamin is essential for the red blood production therefore insufficient
supply of it interferes with the flow of oxygen throughout your body and when the oxygen transportation system is affected like so is usually caused by an autoimmune disorder known as Pernicious Anemia ; This condition occurs when your body fails to provide enough Intrinsic Factor, which is a glycoprotein needed by the intestines for the absorption of vitamin B12.
Moodiness
Vitamin B12 has a vital role for the body as well as the mind. It is essential for
your mental well-being, thus its deficiencies can cause mood disorders like
depression and anxiety.
The main reason for that is that Vitamin B12 is required
to creat neurotransmitters such as serotonin and dopamine; these two have a
major role in mood and humor control and certainly in the well functioning of the
brain, depression could be the result of the low levels of these chemicals.
faintness and difficulty breathing
Vertigo and dizziness are also frequents in vitamin B12 insufficiency .The
symptoms are most commonly experienced when you suddenly change positions
such as getting up after sitting or lying down,or after a tough physical exercise.
And as it was mentioned before It is due to the lacking of the red blood cells resulting in low oxygen levels, and body cells are unable to function
effectively.
