Pregnancy Weight Gain

Pregnancy Weight Gain

It is normal that a pregnant woman will gain weight. This is because the body of a  pregnant woman is preparing to carry a life inside her womb. The nutrients required for the proper growth of the infant must come from its mothers body. During the pregnancy there will be formation of  placenta, amniotic fluid, fat tissues etc which in turn add weight. The scale of weight gain will be different for different people as it depends on many factors like the weight at the time of conception, height, race, intake of food etc.

Healthy Weight Gain

If the body mass index which is calculated by comparing the height and weight of a pregnant woman at the time of conception is in a healthy range which is between 18.5 and 24.9 then weight gain of   25 to 35 pounds during her pregnancy is normal. If she is an under weight women having a body mass index less than 18.5 then for having a healthy baby she should gain weight between 28 to 40 pounds. If a  woman is overweight at the time of conception that is having a body mass index between 25 to 29.9  then she should limit her weight gain to 15 to 25 pounds.
