Skinny while pregnant: Is "Mommy-rexia" a problem?

An article on Today Moms discusses a possible new trend: "Skinny while pregnant" -- also dubbed "Mommy-rexia." Article author Kavita Varma-White points out how the onslaught of pin-thin celebrities who don't appear to gain much weight during pregnancy and then immediately return to their impossibly thin frames within weeks after giving birth might be contributing to this. Varma-White notes that some maternity clothing companies sell size 0 clothes. Add to it the idea that women can stay extremely thin while pregnant, and Varma-White says experts are worried. “It absolutely can have a devastating effect on a woman who is very highly conscious about her weight,” says psychotherapist Robi Ludwig. “At its extreme, onlookers have created a buzzword for the trend: Mommy-rexia. Though not a medical diagnosis, doctors say if taken too far gaining too few pregnancy pounds can also be bad for the baby.” (Source: Today Moms) We're so used to hearing about obesity and pregnancy that the issue of "skinny while pregnant" is far less prevalent. However, it's a concern. So what is a healthy amount of weight to gain during pregnancy? The American Pregnancy Association gives the following guidelines:

• 25-35 pounds if you were a healthy weight before pregnancy, with a BMI of 18.5-24.9.
• 28-40 pounds if you were underweight before pregnancy with a BMI of less than 18.5.
• 15-25 pounds if you were overweight before pregnancy with a BMI of 25-29.9.
• 11-20 pounds if you were obese before pregnancy with a BMI of over 30.

A Today Mom poll that collected over 5,000 opinions asked the question, "When you see someone who is skinny while pregnant, are you..." The following is the breakdown of responses:

• 22.6% Impressed, thinking, "Wow, she looks great"
• 25.7% Envious, thinking, "How does she do it?"
• 51.7% Horrified, thinking, "Why doesn' t she eat more?"

Experts agree that if you want a healthy baby, you have to be healthy. While some women clearly have smaller frames (and some women do have problems gaining an adequate amount of weight during pregnancy), intentionally limiting weight gain during pregnancy to amounts below those medically recommended is not safe for you or your baby.
