Physiological jaundice is a common condition in newborns, characterized by a yellowish tint to the skin and eyes. It typically occurs due to an excess of bilirubin, a yellow pigment produced during the breakdown of red blood cells. In newborns, the liver may take some time to process bilirubin efficiently, leading to its accumulation in the bloodstream and subsequent discoloration of the skin and eyes.
Types of Physiological Jaundice:
Physiological jaundice in newborns is categorized as unconjugated hyperbilirubinemia, meaning the bilirubin is not effectively processed by the liver. This is different from other forms of jaundice that may occur due to underlying medical conditions.
Common Causes of Physiological Jaundice:
- Immature liver function in newborns
- Rapid breakdown of fetal red blood cells
- Delayed onset of liver enzymes
- Breastfeeding difficulties in newborns
- Blood group incompatibility between mother and baby (Rh or ABO incompatibility)
- Dehydration in newborns
- Delayed passage of meconium (first stool)
- Prematurity
- Polycythemia (high red blood cell count)
- Maternal diabetes
- Maternal use of certain medications during pregnancy
- Maternal smoking during pregnancy
- Infection in newborns
- Genetic factors affecting bilirubin metabolism
- East Asian or Mediterranean descent (increased risk due to genetic factors)
- Twin-to-twin transfusion syndrome (in pregnancies with identical twins)
- Low birth weight
- Maternal age over 35
- Maternal obesity
- Maternal hypertension
Symptoms of Physiological Jaundice:
- Yellowing of the skin and whites of the eyes
- Pale stools
- Dark urine
- Difficulty waking for feeds
- Poor weight gain
- Irritability
- High-pitched crying
- Decreased muscle tone
- Excessive sleepiness
- Difficulty breastfeeding
- Fever
- Abdominal swelling
- Vomiting
- Unusual crying or fussiness
- Reduced number of wet diapers
- Poor sucking reflex
- Unexplained bruising
- Swollen abdomen
- Lethargy
- Arching of the body during feeding
