Pernicious Anemia

Pernicious anemia is an autoimmune condition where the immune system mistakenly attacks the stomach cells that produce a protein called intrinsic factor. This protein is essential for absorbing vitamin B12 from food. Without enough B12, the body can't make enough healthy red blood cells, leading to anemia. Symptoms can include fatigue, weakness, and even neurological issues. It is a lifelong condition that usually requires vitamin B12 supplements or injections to manage effectively. Early diagnosis and treatment are important to prevent complications and maintain overall health.
