Vitamin B12 Deficiency Symptoms
Some signs and symptoms of Vitamin B12 deficiency that you need to know, among others:
Pale or yellow skin
People whose body lack of vitamin B12 often look pale or have the little yellow color of the skin as well as white eyes. This is because lack of vitamin B12 will cause problems with the production of the body’s red blood cells.
Vitamin B12 plays an important role in the production of DNA needed to create red blood cells in the body. Without it, the instructions for building cells become incomplete and cannot divide.
These red blood cells are too large to be removed from the bone marrow and into circulation. Therefore, if it does not have many red blood cells circulating throughout the body, it will cause the skin to look pale or yellow.
Weak and easily tired
Another symptom that will be felt due to the body lacking vitamin B12 is easily tired and weak. This happens because it does not have enough vitamin B12 to make red blood cells that transport oxygen throughout the body.
As a result, the body is unable to transport oxygen efficiently to the body’s cells and makes a person who is lacking vitamin B12 weak and limp. People with pernicious anemia do not produce enough important proteins referred to as intrinsic factors.
Intrinsic factors are essential to prevent the lack of vitamin B12 in the body because the vitamins in the gut will bind and can be absorbed well.

Glossitis is a term used to describe inflammation of the tongue. If the tongue is inflamed, it will usually change color, shape, and pain until it swells. In addition to being painful, glossitis can change the way you eat and talks.
