GESTATIONAL AGE AND BIRTH                              WEIGHT 


Gestational age is the age in weeks at which the baby is born,
Baby can be pre-term and post-term.

    Pre-term or premature baby is one born before the 37th week of pregnancy. Fully term baby in one born after the 37th
week of pregnancy. It is 40+ 2 weeks of pregnancy. Post-term or post mature is one born after the 42nd week of pregnancy.

     In full term, the baby is usually relatively normal. There is neither birth anoxia nor asphyxia. Nutrition and oxygenation
are adequate.

     In post maturity it is known that after the 42nd week of pregnancy, the placenta naturally begins to degenerate. The baby then suffers from placental insufficiency. There is birth anoxia leading to fetal distress and there is also passage of meconium. This may lead to intra uterine death.

    The post mature baby when born has the following features :
a. Bright face and shiny eyes.
b. Dry and peeling skin covered with meconium.
c. There is usually meconium aspiration.
