This is not gynaecomastia surgery: understanding the genuine difference
The first thing to establish about male chest contouring after weight loss is that it is not gynaecomastia surgery, even though clinics frequently use the same word for both. Gynaecomastia is glandular tissue, and it is removed through a small incision at the edge of the areola, usually with liposuction, leaving almost no visible scar. After major weight loss the gland is rarely the problem. The problem is skin that no longer fits, a nipple that has slid down the chest, and often a roll continuing round the side into the back. Treating that means excising skin, and excising skin means long scars.
Those scars are the central issue of this operation and they deserve more discussion than they usually get. A woman having equivalent surgery has a bra and a swimming costume to place a scar under. A man has neither. A horizontal scar in the chest crease is the least conspicuous option and it is still plainly visible without a shirt, and an extended scar carried round toward the back is longer still. Men who understood this beforehand consistently report it was worth it; men who expected the near-invisible result of gynaecomastia surgery do not.
