Pseudo-Gynecomastia (Fat-Related Male Breast Enlargement)

The normal male breast contains a small amount of glandular tissue along with fat. The glandular tissue sits just under the nipple and feels firmer—often like a small lump—compared to the softer surrounding fat.

Pseudo-gynecomastia occurs when excess fat, not excess glandular tissue, causes the chest to appear enlarged. This is very common in older men and in younger men who are overweight. Certain medications and drugs, including marijuana, may also contribute to this condition.

Because the enlargement is mainly due to fat, liposuction is the ideal treatment. By removing the excess fat, we can reduce the breast size and restore a flatter, more masculine chest—with no visible scars.

Pseudo-gynecomastia is very common.

• In overweight or obese men, studies suggest it can affect up to 60–70% at some point in their lives.

• Its frequency increases with age, as body fat distribution changes and testosterone levels naturally decline.

• It is also commonly seen in younger men with higher body fat, even when hormone levels are normal.

Unlike true gynecomastia, pseudo-gynecomastia is caused almost entirely by excess fat, not enlarged glandular tissue—which is why liposuction alone is usually sufficient and leaves no visible scars.

Men with fat-dominant breast enlargement are excellent candidates for liposuction-only breast reduction.
