Gynecomastia vanishes without treatment in less than two years. But in some patients treatment may be needed if gynecomastia doesn't improve on its own or if it causes significant pain and embarrassment...avoid junk foods,carbohydrates like rice etc,avoid oily foods...add proteins and fibre rich foods to your diet with green tea,green leafy vegetables, fruits...do regular exercise at least 2 hours a day....Medications used to treat breast cancer and other conditions, such as tamoxifen and raloxifene may be helpful for some men with gynecomastia....if no improvements to medications you can go for surgery....Two gynecomastia surgery options are:
Liposuction. This surgery removes breast fat, but not the breast gland tissue itself.
Mastectomy. This type of surgery removes the breast gland tissue. The surgery is often done endoscopically, meaning only small incisions are used. This less invasive type of surgery involves less recovery time...consult nearest surgeon they will do the needful.
