Most men with gynecomastia are candidates for male breast reduction surgery, but the best candidates are near their ideal weight and have no significant health problems. If you are overweight, we might advise you to try to lose weight first. Sometimes, weight loss can correct gynecomastia without surgery if the excess breast tissue is fat and not glandular tissue. If not, substantial weight loss after surgery could cause further sagging of your skin, and a revisionary surgery could be necessary.
