Women who have excessive weight gain during pregnancy will suffer with more pregnancy complications than those women who gain a healthy amount of weight.
Women are obviously going to gain weight during pregnancy. Not only do they have a baby in there, but they also have fluid and the placenta. Although weight gain is expected, there is a healthy amount of weight that each woman should gain during their pregnancy. Many studies have suggested that women who gain too much during pregnancy are going to suffer with more pregnancy and delivery complications.
One study shows that when pregnant women gain 20 pounds over the guideline amount they have significantly higher rates of heart failure and severe high blood pressure (which can result in needing a transfusion, or ventilation).
The women who are gaining the most weight during pregnancy are those mothers who are overweight, or who are obese before getting pregnant. Women who are in the normal BMI range of 18.5-24.9 are encouraged to gain 25 to 35 pounds during their pregnancy. Those women who's BMI is below 18.5 (underweight) should gain about 28 to 40 pounds. Those women who are overweight before getting pregnant and have a BMI between 25 and 29.9 should only be gaining 11 to 20 pounds during pregnancy.
It is very important to be as healthy as you possibly can during pregnancy. Women sometimes don't realize how much their health and their weight is impacting their unborn child. Some women still believe the old adage of "eating for two" which simply is not true. Women should still be exercising and should only be eating a couple hundred extra calories while pregnant.
Many doctor's and physician don't mention the weight gain to their patients, because it is something that makes the women feel sensitive. However, excessive weight gain during pregnancy should not be glossed over and should definitely be brought to the attention of the mother. Some pregnant women do not know how much their weight gain is affecting their child and how detrimental it can be to their pregnancy and delivery.
