Exposure of alcohol in pregnancy:

  • An association between alcohol drinking in pregnancy and fetal alcohol syndrome has been reported. The side-effects of alcohol include miscarriage, intrauterine growth restriction, microcephaly, mental retardation, behavioural problem after birth;
  • The exact limit of alcohol exposure in pregnancy which is safe remains unknown. Some recommend not more than 1-2 units, once to twice per week;
  • Although an association between even a small amount of alcohol exposure in pregnancy and subsequent neonatal mental or developmental problem has been reported, fetal alcohol syndrome is not commonly seen clinically nowadays despite pregnant women might be exposed to occasional drinking;
  • fetal morphology scan and serial ultrasound scans for fetal growth are advised. The diagnosis might not be made antenatally
