How long does it take for gynecomastia to disappear?

Gynecomastia: At your age gynecomastia is permanent.weight lifting can make them a bit less prominent. However, see a plastic surgeon for a possible surgical approach

It Depends: In general, gynecomastia during puberty years resolves within 3 years of appearance. Since you are 35, it is not likely to disappear unless a medication is the underlying cause. See your primary care physician and consult with a board certified plastic surgeon to discuss your specific situation and possible options. Best wishes!
