Pregnancy is a time to pay attention to your weight. But ... do not be happy if you've "only put on ten pounds" Be happy when your weight has increased enough to bring a healthy baby to the world!
If your weight does not increase enough during pregnancy, you have a higher chance of having a baby with a low birth weight, and are more likely to have an early delivery. However, if you have gained too much, delivery can be difficult and you may need a caesarean (BMI> 30).
|BMI||Class||Potential gain||1st trimester||2st/3rd trimester|
|Lower than 18.5||Underweight||27.5-39.6 lbs||-||1.3 lbs/wk|
|18.5 - 24.9||Normal||25.3-35 lbs||1.1 lbs/month||1.3 lbs/wk|
|25.0 - 29.9||Overweight||15.4-25.3 lbs||1.1 lbs/month||0.75 lbs/wk|
|30.0 and over||Obese||11-19.8 lbs||1.1 lbs/month||0.55 lbs/wk|
Note 1: Research has shown that women have a higher risk of obesity if they gain more than the recommended weight gain during pregnancy.
Note 2: Smoking and drinking also leads to a lower birth weight. If you drink and / or smoke, you have to start thinking seriously about a different lifestyle.
Note 3: These figures apply to a single pregnancy and do not apply to multiple births. If you expect twins, the recommended weight gain is 37 to 48 pounds. (17 to 22 kilos) If you were already overweight before the pregnancy you have to gain less, if you were underweight then you have to gain more. If you had a normal weight for the twin pregnancy, you must gain less than 2 pounds per week in the 2nd and 3rd trimester.
