no circumcision will not cause weight loss (other than the weight of the foreskin that was removed) but it is normal for newborns to lose a bit of weight in the first week and then gain it back to the birth weight level at the two week visit. if this child has not returned to his birth weight he will need to have weekly weights and his intake monitored if he is on formula. if he is breast fed and nursing well this is good. nothing to worry about at this point but his weight will need to be carefully monitored. if his is not gaining weight the pediatrician will take it to the next evaluative level.
will circumcision cause weight loss in baby? . grandson is 3 weeks old. he had his circumcision 4 days ago. he was weighed today and lost 250 grams in total since birth. he is following all other chart measurements perfectly (length head growth filling in of limbs et cetera). my daughter is worried after the doctor said he should be at least back to his birth weight of 3780 grams. thanks for your wonderful site and service . tim mackinnon. tim@maidinmontreal. com
