Pernicious Anemia | Vitamin B12 deficiency | Causes | Treatment Prevention by Priyanka ma'am Pernicious anemia is an autoimmune condition that prevents the body from absorbing sufficient vitamin B12, leading to a deficiency and potentially causing a type of anemia called macrocytic anemia. Here's a more detailed explanation: What it is: Pernicious anemia is a type of vitamin B12 deficiency anemia, where the body's ability to absorb B12 is impaired, resulting in fewer red blood cells carrying oxygen. Cause: It's an autoimmune disorder where the body attacks the cells in the stomach that produce intrinsic factor, a protein needed to absorb B12. Symptoms: Symptoms can include fatigue, weakness, pale skin, shortness of breath, and neurological issues like numbness or tingling in the hands and feet. Diagnosis: Pernicious anemia is diagnosed through blood tests that check for low B12 levels and the presence of antibodies that attack intrinsic factor or parietal cells. Treatment: Treatment typically involves B12 injections or high-dose oral B12 supplements to replenish the body's B12 stores.
