Scientifically speaking, the body mass index is an expression of the mass - height . Not a scientist (and do not play one on TV ) ? An explanation might be more your speed : BMI is a way to establish a healthy weight range for most people . Determine your BMI with the following table.
Why BMI ?
It's not a perfect system - for example , people with super- muscular bodies end with a higher label obese when you are far away BMI . But this is a pretty good reality check , because most people can use BMI to determine if they are overweight or height.
If your BMI is less than 18.5 (not shown in this table) , you are considered insufficient. This means that your goal of weight gain at the end of your pregnancy, it is likely that between 28 and 40 pounds.
If your BMI is between 18.5 and 25 is considered an average weight and should probably win 25-35 pounds during pregnancy.
If your BMI is between 26 and 29 years , you are considered overweight and probably should win between 15 and 25 pounds during pregnancy .
And if your BMI is over 29 , you are considered obese and probably should gain 11-20 pounds by the end of your pregnancy - and talk to your doctor about your weight gain goals .
If you are pregnant with twins ( and eat for three ), recommendations for weight gain for women with an average weight of 37-54 pounds. Overweight women should gain 31 to 50 pounds and obese women should gain 25-42 pounds.
However, your body mass index is not a definitive answer on how to win - just a good starting point. Your doctor will be able to determine exactly how much you need to mention during their pregnancy.
