Fetal macrosomia defined as birth weight greater than 90% for gestational age is an upcoming challenge in the field of obstetrics due to its rising incidence. Obesity, previous history of macrosomia, multiparity, diabetes and post-dated pregnancy are few risk factors associated with macrosomia.

A 30 year old patient second gravida with one living issue at 39 weeks of pregnancy was admitted on 30 May 2019. She was referred from a civil hospital due to big baby and previous LSCS status, which was performed three years back for postdatism with big baby and failure of induction. She had delivered a 4.6 kg female baby and her postpartum period was uneventful.

At the time of admission her vitals were within normal limits. There was no pallor, edema, thyroid swelling or any significant lymphadenopathy. Her BMI was 26.6kg/m². No abnormality was detected on respiratory, cardiovascular or CNS examination. Per abdomen examination - fundal height was term size with foetus in longitudinal lie and cephalic presentation. Foetal heart rate was 138/min with birth weight clinically 4.5kg with no uterine contractions and scar tenderness. Her hematological, biochemical and serological parameters were normal and random blood sugar was 88 mg%. GCT was 84mg/dl.

There is no precise definition of macrosomia. Macrosomia is described as a newborn with an excessive birth weight. According to ACOG foetal macrosomia has been defined in several different ways, including birth weight of 4000-4500g (8 lb, 13 oz to 9 lb, 15 oz) or greater than 90% for gestational age after correcting for neonatal sex and ethnicity (90th percentile). A diagnosis of fetal macrosomia can be made only by measuring birth weight after delivery; therefore, the condition is confirmed only after delivery of the neonate.
