Unilateral gynecomastia, age 20 - Can I make it even without surgery?

Hi! I am sorry to hear about your situation. It sounds like you have been trying hard to try to fix this on your own. Unfortunately, it seems like you might need to seek professional help.
When you want permanent results for gynecomastia treatment, you must go through surgery. There are many different types of surgery that can be done to correct this condition. The type of surgery depends on how severe your case is. Some of the most popular treatments include:
• Liposuction: This procedure removes excess fat from specific areas of the body. In addition, liposuction can remove fatty deposits under the breasts.
• Reduction Mammoplasty: This procedure reduces the size of the breast.
• Augmentation Mammoplasty: This operation increases the volume of the breast.
If you decide to undergo surgery, we recommend that you see a plastic surgeon who specializes in cosmetic surgery. Your doctor should perform a physical exam and discuss with you all possible options available to treat your condition. We hope you found this information useful.

While much of the male breast is fatty tissue that may reduce in size with losing weight, actual breast tissue is almost impossible to fix without surgery. Luckily this can be done through a 1/2 inch incision in the breast crease, and the scar typically heals beautifully.
