Vitamin B12 Deficiency
Vitamin B12 Deficiency (pronunciation: vi-ta-min B12 de-fi-cien-cy) is a medical condition characterized by low levels of Vitamin B12 in the body.
Etymology
The term "Vitamin B12 Deficiency" is derived from the English words "vitamin", "B12", and "deficiency". "Vitamin" is derived from the Latin word "vita" meaning "life" and the chemical suffix "-amine". "B12" refers to the specific type of vitamin, and "deficiency" comes from the Latin word "deficientia" meaning "a lack or shortage".
Symptoms
Symptoms of Vitamin B12 Deficiency may include fatigue, weakness, constipation, loss of appetite, weight loss, and megaloblastic anemia. Neurological changes, such as numbness and tingling in the hands and feet, can also occur. Advanced cases may involve confusion, depression, poor balance, and memory loss.
Causes
Vitamin B12 Deficiency is typically caused by dietary deficiency, but can also be due to malabsorption, certain genetic disorders, or the use of certain medications. Pernicious Anemia, a condition that prevents the body from absorbing Vitamin B12 in the intestine, is a common cause of Vitamin B12 Deficiency.
Treatment
Treatment for Vitamin B12 Deficiency usually involves supplementation of Vitamin B12 through high-dose oral supplements or injections, and treating the underlying cause of the deficiency.
