Understand the Truth About Gynecomastia Many patients initially think they simply have fat on their chests. They try fitness and dieting but find that the "fat lumps" persist stubbornly. In fact, gynecomastia is caused by benign hyperplasia of mammary glands or adipose tissue, while simple obesity (pseudo-gynecomastia) is due to fat accumulation.

Gynecomastia is the benign enlargement of male breast tissue, caused by estrogen-androgen imbalance. Common in infants, teens, and older men, it can involve glandular tissue, fat, or both. While often a cosmetic concern, it may cause distress. Treatments include medication or surgery (liposuction/excision) if persistent. Effective correction is achievable.
