In the hands of an experienced plastic surgeon, the results of your male breast reduction should be permanent. However, if you wind up taking certain drugs or gain an extensive amount of weight post surgery, this could adversely affect your results. Most of the time, a recurrence of gynecomastia is due to an inadequate glandular excision during your initial surgery and/or liposuction alone when there should have also been an excision. This is why seeing a board certified plastic surgery with extensive gynecomastia experience is so important.
