It is certainly possible to have recurrence of gyneomastia following treatment. Especially if one has had treatment when one is a younger teenager, the chest is still developing. There is always some breast tissue left behind following correction of gynecomastia and it is possible for this to enlarge. Also, with weight gain, obviously fatty tissue can build up also and cause a recurrence. The most common sense management would be to seek out your original gynecomastia surgeon for evaluation. He or she will review possible reasons for recurrence-could this be partially medical or partially weight gain? The original surgeon would also know exactly what had been performed on the first surgery and may be able to counsel you as to what the next best steps are.
