Jaundice, also known as icterus, is a yellowish or greenish pigmentation of the skin and whites. In jaundice secondary to hemolysis, the increased production of bilirubin leads to the increased production of urine-urobilinogen. Bilirubin is not. Prehepatic causes of jaundice include hemolysis and hematoma resorption, The conjugated (direct) bilirubin level is often elevated by alcohol, acute hepatitis B or C and polyarthralgias.5–7.

Neonatal jaundice may be on account of different parameters such as birth weight, gestational age, premature rupture of membranes, maternal infectious diseases or other illness during pregnancy, having different sources of origin, hence having different types This review article focuses on a brief introduction to jaundice, its types and causes, measuring the bilirubin level, clinical approaches towards hyperbilirubinemia, different precautionary measures for the parents of babies suffering from hyperbilirubinemia and different remedial therapeutic measures for its treatment.
Hyperbilirubinemia can be treated easily without or with a minimal adverse effect with phototherapy 71 The classic definition of jaundice is a serum bilirubin level greater than 2.

Jaundice (SBR >50 μmol /L) is one of the most common physical signs observed on the state of hydration and consideration of the possibility of an acute haemolytic process and/or infection. SBR Chart - preterm and ( bytes) Phototherapy causes photodegradation of bilirubin in the infant's skin.
Occasionally, patients may present with jaundice and some extrahepatic manifestations of liver disease.
This conjugated bilirubin is then returned to the blood, probably by rupture of the congested bile canaliculi and direct emptying of the bile into the lymph leaving the liver. Jaundice typically results from the deposition of unconjugated bilirubin pigment in the skin and mucus membranes.
