Rapid fetal weight gain isn’t good for the baby or the mother. It increases the chances of needing a C-section and raises risks like gestational diabetes and complications during and after birth. So, what should a mother pay attention to when the fetus is found to be overweight?

A fetus is nourished and develops in the mother's uterus, residing in the amniotic sac throughout the pregnancy. During this time, the fetus is active and develops its circulatory, digestive, and urinary systems. So, how does a fetus excrete waste in the womb?

Pregnant women at risk of preterm labor or threatened preterm labor are often prescribed corticosteroid injections to promote fetal lung maturity. So, what are the effects of corticosteroid injections on the fetus, and when should pregnant women receive them to maximize their effectiveness?

Hello doctors of Vinmec hospital, I am currently 32 weeks pregnant. After an ultrasound, the doctor concluded that the fetus weighs 1.6 kg. Could you please tell me if this weight means my baby is underweight? How much should a 32-week fetus weigh to meet the standard? Thank you!

If the biparietal diameter, the fetal head measurement, is larger than normal, a vaginal delivery could pose significant risks for both the mother and baby during labor. However, for more precise assessments, doctors will combine the biparietal diameter measurement with other fetal parameters, such as abdominal circumference and femur length.

Fetal head circumference is an important indicator, helping to assess fetal development, and at the same time detect abnormal signs of the baby right from the time it is in the mother's womb. This helps to limit the risk of birth defects in children, especially microcephaly.
