What is sickle cell disease characterized by?

Acute, reoccurring episodes of tissue, abdominal, and joint pain.

Folic acid deficiency anemia

Preeclampsia Prematurity IUGR stillbirth neonatal lupus congenital heart blocks Increased learning disabilities

Sickle cell disease (SCD)

Recessive autosomal disorder - Hemoglobin S (HbS) causes red blood cells (RBCs) to be sickle-shaped - RBCs are distorted, causing low oxygenation
