Beware of gaining too much/not gaining enough weight!
Gaining too much weight during a pregnancy will make you susceptible to pregnancy induced hypertension. However, recent trends have been seeing mothers-to-be that are too slim. It is said that not gaining enough weight will result in not only a smaller infant but also makes you susceptible to lifestyle related diseases. In any case, weight control during gestation is very important.
How much weight gain is normal during pregnancy?
The weight a pregnant woman gains until birth mostly consists of the weight of the infant (fetus), placenta, amniotic fluid and blood. A newborn's average weight is approximately 3 kilograms. It is said that a mother-to-be's body stores up necessary nutrients for birth and breastfeeding during pregnancy as well. In recent time, weight gain calculated according to each individual's pre-pregnancy weight seems to be the most ideal.
