Difference Between Vitamin B12 Deficiency And Pernicious Anemia
Introduction
Vitamin B12 is an essential nutrient that plays a crucial role in the formation of red blood cells, DNA synthesis, and nerve function. However, many people suffer from Vitamin B12 deficiency and pernicious anemia. Although both conditions are related to a lack of Vitamin B12, they have different causes, symptoms, and treatment options. This article discusses the difference between Vitamin B12 deficiency and pernicious anemia.
What Is Vitamin B12 Deficiency?
Vitamin B12 deficiency occurs when the body does not get enough Vitamin B12 from food or supplements. The primary cause of Vitamin B12 deficiency is a lack of absorption due to the absence of intrinsic factor, a protein produced by the stomach. Other factors that can contribute to Vitamin B12 deficiency include a vegetarian or vegan diet, gastrointestinal disorders, and certain medications.
What Are The Symptoms Of Vitamin B12 Deficiency?
The symptoms of Vitamin B12 deficiency can vary depending on the severity of the deficiency. Mild deficiency may not cause any symptoms, while severe deficiency can lead to serious health problems. Common symptoms of Vitamin B12 deficiency include fatigue, weakness, numbness or tingling in the hands and feet, difficulty walking, and memory problems.
How Is Vitamin B12 Deficiency Treated?
Vitamin B12 deficiency can be treated by taking Vitamin B12 supplements or getting injections. The amount of Vitamin B12 needed to treat the deficiency depends on the severity of the deficiency. In some cases, dietary changes may also be necessary to increase the intake of Vitamin B12-rich foods.
What Is Pernicious Anemia?
Pernicious anemia is a type of anemia that occurs when the body is unable to absorb Vitamin B12 due to the absence of intrinsic factor. This condition is usually caused by an autoimmune disorder in which the immune system attacks the cells in the stomach that produce intrinsic factor. Pernicious anemia is more common in people over the age of 60 and those with a family history of the condition.
What Are The Symptoms Of Pernicious Anemia?
The symptoms of pernicious anemia are similar to those of Vitamin B12 deficiency. However, pernicious anemia can also cause neurological symptoms such as difficulty walking, loss of balance, and confusion. If left untreated, pernicious anemia can lead to serious health problems such as nerve damage and cognitive decline.
How Is Pernicious Anemia Treated?
Pernicious anemia is usually treated by Vitamin B12 injections. In some cases, high-dose oral supplements may also be effective. In addition, treatment may be necessary for any underlying autoimmune disorders that are causing the condition.
Conclusion
In conclusion, although Vitamin B12 deficiency and pernicious anemia are related to a lack of Vitamin B12, they have different causes, symptoms, and treatments. It is important to seek medical attention if you are experiencing symptoms of either condition to receive the proper diagnosis and treatment.
