Sickle cell anemia is a prevalent blood disorder characterized by the abnormal shape of red blood cells. The normal shape of red blood cells is crucial for their smooth flow within the blood vessels. However, when the shape of these cells becomes altered, they tend to adhere to other irregularly shaped red blood cells, causing various complications. While sickle cell anemia can affect individuals of any race, it is more frequently observed among African-Americans.
Early Symptoms: Swelling of the Hands and Feet
One of the initial indications of the disease is the swelling that occurs in the hands and feet, specifically in the fingers and toes. This swelling, commonly referred to as “dactylitis” or “sausage digit,” is often accompanied by pain. Remarkably, it can manifest in infants even before they reach six months old. However, it is rarely observed in children older than two years. Due to the relatively small size of the blood vessels in the fingers and toes, abnormally shaped red blood cells can easily cluster together, obstructing these vessels. Consequently, this swelling hinders the blood supply to the bones, ultimately leading to bone necrosis.
Tiredness: A Common Symptom of Red Blood Cell Disorders
Red blood cells play a crucial role in delivering oxygen to the body’s cells, providing them with the energy necessary to carry out their functions efficiently. Unfortunately, when red blood cells are impacted by certain diseases, the organs within the body are deprived of this much-needed energy. Consequently, children suffering from such conditions experience constant exhaustion and find it challenging to perform their regular daily activities. In addition to feeling perpetually tired, they may also struggle with weakness and difficulty concentrating. It is important to note that fatigue is not exclusive to sickle cell anemia but can manifest in various types of anemia and numerous other medical conditions as well.
