Anemia Explained: Signs, Symptoms, Types and Treatment

Anemia Definition: Anemia occurs when a person has fewer red blood cells or less hemoglobin than normal, reducing the blood's oxygen-carrying capacity. Key Symptoms: The most common signs include fatigue, weakness, pale skin, shortness of breath (especially during exertion), lightheadedness, and rapid or irregular heartbeats. Iron Deficiency Anemia: This is the most common type, where a lack of iron leads to smaller, paler red blood cells (microcytic, hypochromic anemia), often due to menstrual bleeding, low intake of red meat, or poor absorption. Risk Factors for Iron Deficiency: Women, individuals with gastrointestinal conditions like Crohn's or celiac disease, those who’ve had gastric surgery, and people experiencing chronic blood loss are at higher risk. Anemia of Chronic Disease (Inflammation): Chronic inflammation can limit iron availability and reduce erythropoietin production, leading to normocytic, normochromic anemia despite normal cell appearance. Vitamin B12 Deficiency: B12 is essential for red blood cell maturation and DNA synthesis. A deficiency results in macrocytic (megaloblastic) anemia, common among vegans and people with absorption issues like pernicious anemia. Folate Deficiency Anemia: Similar to B12 deficiency, lack of folate results in macrocytic anemia. It’s particularly relevant in pregnancy and conditions affecting absorption, although it accounts for a smaller percentage of cases. Hemolytic Anemias: These occur when red blood cells are destroyed prematurely. Examples include genetic conditions like sickle cell anemia, thalassemia, and hereditary spherocytosis, as well as acquired causes like certain medications or mechanical damage. Initial Blood Tests: The first tests typically check hemoglobin and hematocrit levels. While low values confirm anemia, they don’t pinpoint the specific type without further testing.
