What is sickle cell anemia?

Contemporary society is developing rapidly, and concurrently, the incidence of various diseases is also rising significantly. Conditions such as sickle cell anemia are becoming increasingly prevalent—particularly among young children, pregnant women, and other vulnerable populations. So, what exactly is sickle cell anemia?

What Is Sickle Cell Anemia?

Anemia is a very common clinical condition with highly complex etiologies. The most frequent type is iron-deficiency anemia. Because the disease often progresses slowly, early symptoms may be nonspecific or subtle. Initial manifestations may include dizziness, tinnitus, impaired memory, pallor, loss of appetite, generalized weakness, and palpitations or shortness of breath upon exertion. Severe anemia may even precipitate cardiac complications, including heart failure.

Additionally, early-stage anemia may present with gastrointestinal symptoms, such as marked anorexia and abdominal distension. Female patients may experience menorrhagia, while affected children may show delayed growth and development and difficulty concentrating. Neonatal anemia detected shortly after birth is commonly attributable to either iron-deficiency anemia or hemolytic anemia. Hemolytic anemia is especially common in newborns, frequently resulting from conditions such as hemolytic jaundice.

Therefore, if a newborn exhibits generalized jaundice (yellowing of the skin and sclera), prompt measurement of serum bilirubin levels is strongly recommended. Markedly elevated bilirubin suggests jaundice as the underlying cause. Accordingly, a comprehensive diagnostic evaluation is essential to determine the precise etiology of neonatal anemia. Iron-deficiency anemia is typically managed with iron supplementation, whereas hemolytic anemia often requires urgent blood transfusion and pharmacologic treatment targeting hyperbilirubinemia.
