Reduction mammoplasty is usually not recommended for women who:
smoke and cannot stop smoking 1-2 months before and after surgery;
suffer from severe obesity (they are asked to lose weight first);
do not want to have any post-operative scars on the chest and are not ready to undergo cosmetic procedures for skin resurfacing.
Doctors suggest postponing surgery if a woman is planning to have a baby or lose weight. Also, pregnant women and girls under 18 years of age are not operated on.
