These sickle-shaped cells are stiff and sticky, leading to blockages in blood vessels that result in pain and other serious health complications (Mangla A,2023). The condition primarily affects individuals of African, Mediterranean, Middle Eastern, and Indian descent. According to the Centers for Disease Control and Prevention (CDC), about 1 in 365 African American babies are born with sickle cell disease (SCD), while 1 in 13 carry the sickle cell trait. This chronic disease can have life-threatening outcomes, especially during recurrent vaso-occlusive crises and infections, which can cause long-term organ damage. Etiology and Risk Factors Sickle cell anemia results from a mutation in the HBB gene, which encodes the beta- globin subunit of hemoglobin (Elendu, C, 2023). This genetic mutation is inherited in an autosomal recessive pattern, meaning an individual must inherit two copies of the mutated gene to develop the condition. Those with just one copy are carriers, often referred to as having sickle cell trait, and usually do not show symptoms (Mangla A,2023). The risk of developing sickle cell anemia increases if both parents are carriers, as it raises the chances of passing the gene to their children. Symptoms generally begin to appear around five months of age, indicating that age plays a role in disease progression. While gender does not significantly affect the prevalence of the disease, women with SCD may encounter pregnancy-related complications. Certain environmental factors, such as high altitudes, extreme temperatures, and dehydration, can trigger sickle cell crises. Additionally, lifestyle choices like physical activity and maintaining proper hydration can influence the frequency and severity of these crises. Pathophysiological Processes At the cellular level, sickle cell anemia involves the production of abnormal hemoglobin (HbS), which leads to the sickling of red blood cells when oxygen levels are low. These sickled cells have a shorter lifespan of 10-20 days, compared to the 120-day lifespan of healthy red blood cells, causing chronic hemolytic anemia (Elendu, C, 2023). These abnormal cells tend to clump together, blocking small blood vessels and reducing oxygen delivery to tissues, resulting in pain crises (vaso-occlusive episodes) and ischemic damage to organs and tissues (Mangla A,2023). Repeated sickling episodes contribute to progressive damage in organs like the kidneys and spleen. The body attempts to compensate by increasing the production of immature red blood cells (reticulocytes), though this is
