Male, 30s, good physical shape. Gynecomastia flare up out of the blue. Unilateral gyno grade1-4 in severity & grade1

Healthy male patients with excess breast tissue or unwanted breast development who have no underlying breast disease.Men who desire improved physical and aesthetic appearance should have realistic expectations based on their condition and the procedure performed. You should meet with a board certified plastic surgeon to be able to get a formal diagnosis and to be able to decide on a course of treatment if necessary.

If you are only experiencing the gynecomastia on one side, I would only treat that side. You may never get it on the other side. Schedule a consultation with a board certified plastic surgeon to be assessed in person and discuss. Best of luck.

Hello and thank you for your question. I have encountered many cases of unilateral gynecomastia. On the side that is affected, it is easy to removed the volume. If the side that is lesser affected is minimal to non-existant I would not operate on that side. If it is minor I would consider removing it. Best Wishes

something doesn't sound exactly right. Is there any chance you recently started taking bodybuilding steroids or over-the-counter supplements which are often filled with steroids without the patient knowing it. If that's not the case you might want to have this looked into a little more carefully and possibly biopsied. 

if you have gynecomastia on one side it is best to treat that side only, unless the other side has a palpable abnormality there is no reason to treat it. There is no guarantee you will develop gynecomastia on the other side.
