 Introduction Anemia of Chronic Disease (ACD), also known as Anemia of Inflammation (AI), is the second most common type of anemia after iron deficiency anemia. It develops as a complication of chronic inflammatory disorders rather than a primary hematologic disease. Patients with chronic infections, autoimmune diseases, malignancies, or chronic kidney disease are at increased risk of developing this condition. Unlike iron deficiency anemia, the body usually contains sufficient or even increased iron stores. However, persistent inflammation alters normal iron metabolism, preventing iron from being efficiently utilized for hemoglobin synthesis and red blood cell production. As a result, patients develop mild to moderate anemia despite having adequate iron reserves. Anemia of Chronic Disease is one of the most common types of anemia.

Figure 1. Illustration showing defective heme synthesis and mitochondrial iron accumulation in sideroblastic anemia.  Introduction Sideroblastic anemia (SA) is a rare and heterogeneous group of blood disorders caused by defective heme synthesis. Although the body has adequate or even excessive iron stores, the iron cannot be effectively incorporated into hemoglobin. Instead, it accumulates within the mitochondria of developing erythroblasts, forming ring sideroblasts, the characteristic hallmark of the disease. Sideroblastic anemia may be either congenital or acquired. Inherited forms are usually caused by genetic mutations affecting enzymes involved in heme synthesis, whereas acquired forms are associated with myelodysplastic syndrome (MDS), chronic alcohol use, certain medications, nutritional deficiencies, and heavy metal poisoning. Early diagnosis is essential because prolonged iron overload may damage vital organs such as the liver, heart, and endocrine glands. Sideroblastic...

 Introduction Megaloblastic anemia is a type of macrocytic anemia caused by impaired DNA synthesis, resulting in the production of abnormally large and immature red blood cell precursors known as megaloblasts in the bone marrow. The condition most commonly develops because of vitamin B12 (cobalamin) deficiency or folate (vitamin B9) deficiency, both of which are essential for normal cell division and red blood cell maturation. Although red blood cells are primarily affected, severe cases may also reduce white blood cells and platelets, leading to pancytopenia. Patients often present with fatigue, weakness, pallor, and shortness of breath, while prolonged vitamin B12 deficiency may cause neurological complications that can become irreversible if treatment is delayed. Early diagnosis and appropriate vitamin replacement usually result in an excellent prognosis. What is Megaloblastic Anemia? Megaloblastic anemia is a hematological disorder characterized by ineffective erythropoiesis ca...

Introduction Iron deficiency anemia (IDA) is the most common nutritional deficiency and the leading cause of anemia worldwide. It occurs when the body's iron stores become insufficient to meet the demands of hemoglobin synthesis, resulting in reduced oxygen-carrying capacity of red blood cells. Iron deficiency develops gradually, beginning with depletion of iron stores, followed by impaired red blood cell production, and eventually progressing to anemia. Early diagnosis and appropriate treatment are essential to prevent complications and improve patient. Iron deficiency anemia is one of the most common types of anemia.

What Is Iron Deficiency Anemia? Definition Iron deficiency anemia is a microcytic hypochromic anemia caused by inadequate iron availability for hemoglobin synthesis. Since iro...

 Table of Contents What Is Anemia? How Red Blood Cells Work Causes of Anemia Classification of Anemia Symptoms and Signs Risk Factors Diagnosis Treatment Prevention Complications Prognosis When to See a Doctor Frequently Asked Questions Conclusion What Is Anemia? Anemia is one of the most common blood disorders worldwide. It develops when the body has too few healthy red blood cells (RBCs) or when the amount of hemoglobin is lower than normal. Since hemoglobin is responsible for transporting oxygen from the lungs to body tissues, a reduction in red blood cells or hemoglobin limits oxygen delivery throughout the body As a result, patients with anemia often experience fatigue, weakness, shortness of breath, dizziness, and reduced physical performance. Depending on its cause and severity, anemia may range from a mild condition with few symptoms to a serious medical disorder requiring urgent treatment According to the World Health Organization (WHO), anemia affects hundreds of millions...
