The ideal weight gain

During pregnancy, doctors recommend taking between 9 and 13 kilos.
Of course, this range is to be qualified according to your original weight.
So, what is your ideal weight?

The body mass index or BMI

It's going to help you determine exactly how much weight you take during your pregnancy. The BMI is the result of weight divided by height squared.

To simply could let me give an example
if you weigh 60 kg and measuring 1.70 cm you, you simply divide 60
1.70 per square. This gives 1.70 * 1.70 = 2.89 and 60 / 2.89 = 20.76.
Your BMI is therefore 20.76

Of course, you must calculate your BMI by weight than you had before your pregnancy.

Your BMI is below 18.5

Your weight before pregnancy is inadequate, then you can take more weight than the average woman. Your ideal weight is between 14 and 18 kg.

Your BMI is between 18.5 and 25
You are in the middle, so you can take the weight usually
advised by doctors, ie between 9 and 13 kg.

Your BMI over 25
You are already overweight, then you must monitor your weight, see a specialist from a BMI above 27.
Your weight must be between 8 and 11 pounds, no more!
