Weight Gain During Pregnancy
Pregnancy weight gain is probably one of the least endearing of all pregnancy symptoms. Of course, a certain amount of weight gain is necessary to ensure proper development of the baby, but just how much is too much - or too little, for that matter?

On the other hand, women who are underweight prior to conception may gain up to 40 pounds. This is especially important since underweight women stand to pose the greatest health risks to their babies.
Finally, women who are overweight should gain a maximum of 25 pounds. However, if you have been diagnosed as clinically obese, then it is recommended your pregnancy weight not exceed 15 pounds.
Of course, the amount of weight gain that is considered normal increases substantially for those carrying twins or multiple babies. In this case, the amount of recommended weight gain increases to about 45 pounds, depending on your pre-pregnancy weight and the amount of babies you are carrying.
