Gestational Weight Gain May Cause Adverse Pregnancy Outcomes

Pregnancy body mass index (BMI) is considered as key indicator of pregnancy outcomes. The normal BMI during pregnancy is 20-24.9 kg/m2. Being underweight or overweight leads to increase the risk in pregnancy complications like preterm birth, low birth weight, post-partum hemorrhage, labor induction, miscarriage and fetal macrosomia.


It is a condition that occurs in obese women or who has BMI greater than 30. It usually begins after 20 weeks of pregnancy in women having problem of high blood pressure, protein in the urine and carrying multiple babies. Due to this, the placenta does not get enough blood. As a result, baby also gets less oxygen and food that leads to low birth weight.

Preterm birth

Postpartum hemorrhage

This condition leads to excessive bleeding after the birth of a baby. This happens due to poor contraction of the uterus following childbirth. It is more common in those who are obese or have a low amount of red blood.

Labor induction

Labor induction is the stimulation of uterine contractions by using medications or other methods to achieve a vaginal birth. It is recommended for various reasons such as when health of the mother or fetus is at risk, mother is obese, date is overdue and placenta abruption.

Fetal macrosomia

This term is used to describes a baby who is significantly much larger than average for their gestational age. The baby born will have a birth weight of more than 8 pounds, 13 ounces. This leads to complications in vaginal delivery and go for C- section. This depends on genetic factors or maternal conditions, like obesity or diabetes.

Spontaneous miscarriage

A miscarriage is the loss of pregnancy before the 20th week of gestation. Miscarriage is common in woman who is having problems related to uterus, hormones, immune- system, diabetes, thyroid or underweight.
