Are compression vests effective for gynecomastia?

NOPE: Gynecomastia is enlargement of the breast tissue. Compressing it will not help it shrink or make it smaller.

No: They help post surgically to prevent fluid accumulation but do nothing to suppress or remodel existing enlarged breast tissues.

After Surgery: Gynecomastia, if persistent, is often best treated with partial excision of the prominent glandular tissue as well as liposuction surgery of the peripheral chest area. If the prominence of the chest wall is caused by adipose tissue, then liposculpture surgery alone may suffice. For patients with excess skin, common after weight loss, skin excision may also be necesary.
