Meconium ileus is a disorder that occurs in newborns in which the meconium, the neonate's first fecal excretion after birth, is abnormally thick and stringy, rather than the collection of mucus and bile that is normally passed.
Breastfeeding is an important risk factor for hyperbilirubinemia in healthy infants and is related to inadequate maternal milk supply in the first few days, decreased caloric intake and delayed passage of meconium.
In children with cystic fibrosis in which meconium ileus becomes evident soon after birth, the prognosis is linked with the primary disease; the median age of survival for cystic fibrosis patients is 30 years.
A newborn may fail to pass meconium (the first stool) within 24 hours of birth, may repeatedly vomit yellow or green colored bile, and may have a distended (swollen, uncomfortable) abdomen.
Meconium aspiration syndrome-Breathing in of meconium (a newborn's first stool) by a fetus or newborn, which can block air passages and interfere with lung expansion.

Meconium ileus in newborns is caused by increased viscosity of waste products in the intestinal tract, and is sometimes secondary to cystic fibrosis.
Infants with cystic fibrosis are more likely to experience meconium ileus (obstruction of a dark green material in the intestine in newborns).
It is used to relieve cord compression, reduce fetal distress caused by meconium staining, and as a correction of decreased amniotic fluid.
In the 13th century opium thebaicum is mentioned by Simon Januensis, physician to Pope Nicholas IV., while meconium was still in use.
