Weight gain is just part of pregnancy. The weight of the fetus, placenta, growing uterus, extra blood and body fluid all account for extra weight. Just how much extra weight a woman should gain during pregnancy has been the topic of debate for quite some time. When obesity was less of a problem, all women were given the same recommendation, but weight differences among women occurred, new guidelines were established. The new weight gain guidelines denounce the old myth that women need to gain a prescribed amount of weight during pregnancy. Moreover, women can successfully lose weight and still maintain a healthy pregnancy from start to finish. 
How Much Do You Weigh?
The question of weight gain during pregnancy used to be answered with a static number for all women. Women were supposed to gain between 25 and 35 pounds during gestation. That suggestion is still accurate, but only for women who start the pregnancy at a normal weight. Before you know how much you should gain during pregnancy you have to admit how much you weigh before pregnancy.
Weight Gain Guidelines
The weight gain guidelines for pregnancy are no longer delivered as one static number. The number will change for women who weigh more or less than normal. There are also special guidelines for women pregnant with multiples. Here are the general guidelines for weight gain during pregnancy.
- Normal BMI: 25 to 35 pounds
- Low BMI: 28 to 40 pounds
- Slightly High BMI (Overweight): 15 to 25 pounds
- Extremely High BMI (Obese): Less than 20 pounds
Now, with those numbers on the board you still need an answer to the question, “Do I have to gain weight during pregnancy?” The answer is no – you don’t have to gain weight during pregnancy. Women who are obese, especially those who’re super obese or morbidly obese, can have a successful pregnancy and LOSE weight the entire time. As long as you eat enough to maintain good health and keep all your prenatal visits, your body will grow to support baby.
