Newborns are prone to hemolytic anemia due to a lack of what?

Neonatal hemolytic anemia typically occurs due to increased destruction of red blood cells exceeding the bone marrow's capacity for blood cell production, commonly caused by a deficiency in red blood cell enzymes.

Under normal circumstances, red blood cells require energy to function. Mature red blood cells do not contain glycogen and usually obtain glucose directly from plasma to generate energy. Glucose contains sugar enzymes that produce substantial energy during the breakdown process, meeting the body's growth requirements and maintaining normal physiological functions. This process plays a significant role in neonatal growth and development. However, the energy derived from glucose fermentation depends on red blood cell enzymes. Since newborns' bodies are not fully developed, a deficiency in these enzymes often prevents them from obtaining sufficient energy, making them prone to hemolytic anemia.

Hemolytic anemia is generally not an independent disease. Besides red blood cell enzyme deficiency, it may also result from structural defects in the red blood cell membrane, immune-mediated hemolytic anemia, vascular hemolytic anemia, infections, or other causes. Timely medical treatment is recommended.
