Type Of Anemia Caused By Lack Of Vitamin B12
Anemia is a condition that occurs when the body lacks enough healthy red blood cells to carry oxygen to the body's tissues. Vitamin B12 plays an essential role in the production of red blood cells. Lack of this vitamin can cause anemia. There are different types of anemia caused by a deficiency of Vitamin B12. In this article, we'll discuss the various types of anemia caused by a lack of Vitamin B12.
Pernicious Anemia
Pernicious anemia is a type of anemia caused by the inability of the body to absorb Vitamin B12. This condition occurs when the body lacks intrinsic factor, a protein produced in the stomach that helps to absorb Vitamin B12. Without intrinsic factor, the body cannot absorb enough Vitamin B12, leading to a deficiency and ultimately resulting in pernicious anemia. Some of the symptoms of pernicious anemia include fatigue, weakness, pale skin, and shortness of breath.
Megaloblastic Anemia
Megaloblastic anemia is another type of anemia caused by a deficiency of Vitamin B12. This type of anemia occurs when the body lacks enough Vitamin B12 to produce healthy red blood cells. As a result, the body produces large, abnormal red blood cells known as megaloblasts. Some of the symptoms of megaloblastic anemia include weakness, fatigue, shortness of breath, and pale skin.
Aplastic Anemia
Aplastic anemia is a condition that occurs when the body doesn't produce enough new blood cells. This type of anemia can be caused by a deficiency of Vitamin B12. When the body lacks enough Vitamin B12, it can't produce enough red blood cells, leading to aplastic anemia. Symptoms of aplastic anemia include fatigue, weakness, dizziness, and shortness of breath.
Hemolytic Anemia
Hemolytic anemia is a type of anemia that occurs when the body destroys red blood cells faster than it can produce them. This condition can also be caused by a deficiency of Vitamin B12. Without enough Vitamin B12, the body can't produce enough red blood cells to replace the ones that are being destroyed. Some of the symptoms of hemolytic anemia include fatigue, weakness, pale skin, and jaundice.
Nerve Damage
Vitamin B12 plays a crucial role in maintaining healthy nerve cells. A deficiency of Vitamin B12 can cause nerve damage, leading to symptoms such as tingling, numbness, and difficulty walking. In severe cases, nerve damage caused by a Vitamin B12 deficiency can be irreversible.
Conclusion
Vitamin B12 plays a vital role in the production of red blood cells and the maintenance of healthy nerve cells. Lack of this vitamin can cause different types of anemia, including pernicious anemia, megaloblastic anemia, aplastic anemia, and hemolytic anemia. In severe cases, a deficiency of Vitamin B12 can also cause nerve damage. If you experience any symptoms of anemia or nerve damage, it's essential to seek medical attention.
