A weight gain of about 4 to 5 kg in the sixth month of pregnancy is generally normal, and is also based on the body mass index of the pregnant woman.
Maternal weight gain can affect the outcome of pregnancy for both mother and child. Excessive maternal weight gain increases the risk of large-for-gestational-age babies, obstructed labor, and birth injuries, while insufficient maternal weight gain increases the incidence of fetal growth restriction, low-birth-weight babies, and other adverse pregnancy outcomes, so it is important to pay attention to weight management during pregnancy. A weight gain of 4-5kg in the 6th month of pregnancy is normal.
Appropriate weight gain during pregnancy facilitates both the maternal and child’s pregnancy condition and natural delivery. Depending on the body mass index (BMI) of the pregnant woman, the weight gain requirement during pregnancy varies.
For those with normal BMI, weight gain during pregnancy can be 11.5~16kg, low weight people can gain 12.5~18kg, and overweight and obese people are allowed to be below the weight gain standard as long as the fetus grows appropriately.
