Neonatal Jaundice: Causes, Symptoms, Treatment, and Prevention
Jaundice is a medical condition characterized by the yellowing of the skin, sclera (the white part of the eyes), and mucous membranes due to elevated levels of bilirubin in the blood. Bilirubin is a yellow pigment produced during the normal breakdown of red blood cells. In a healthy individual, the liver processes and eliminates bilirubin from the body. However, when there is an imbalance between the production and elimination of bilirubin, it can accumulate in the bloodstream and result in the yellow discoloration associated with jaundice.
Jaundice in newborns, commonly referred to as neonatal jaundice, is a prevalent occurrence that can instill worry in parents. This condition is identified by the yellowing of the skin and eyes, a manifestation of elevated bilirubin levels in the infant's blood. To alleviate parental concerns and prioritize the well-being of the newborn, it is imperative to comprehend the causes, symptoms, and appropriate actions to take. This comprehensive exploration delves into various facets of neonatal jaundice, encompassing its origins, observable signs, available treatment options, and preventive measures.
