Anemia Characterized By A Lack Of Vitamin B12
Anemia is a condition wherein the body doesn't have enough red blood cells to carry oxygen throughout the body. This can lead to fatigue, weakness, and shortness of breath. Anemia can be caused by a variety of factors, including a lack of Vitamin B12 in the body.
What is Vitamin B12?
Vitamin B12 is a water-soluble vitamin that plays a crucial role in the production of red blood cells. It is also important for maintaining the health of the nervous system and for the production of DNA. Vitamin B12 is found naturally in animal products such as meat, fish, and dairy. Vegetarians and vegans may be at risk of Vitamin B12 deficiency, as plant-based foods do not contain Vitamin B12.
How does a lack of Vitamin B12 lead to Anemia?
Vitamin B12 is necessary for the production of red blood cells. Without enough Vitamin B12, the body is unable to produce enough red blood cells to carry oxygen throughout the body. This leads to a type of anemia called megaloblastic anemia. Megaloblastic anemia is characterized by red blood cells that are larger than normal and unable to function properly. This can lead to fatigue, weakness, and shortness of breath.
Who is at risk of Vitamin B12 deficiency?
Vegetarians and vegans are at risk of Vitamin B12 deficiency, as plant-based foods do not contain Vitamin B12.

People with certain gastrointestinal disorders, such as Crohn's disease or celiac disease, may also be at risk of Vitamin B12 deficiency.
What are the symptoms of Vitamin B12 deficiency?
