Gynecomastia is a male condition that affects the chest, often occurring during puberty and lasting into adulthood. It creates the look of having larger breasts and a less athletic contour. It is caused by heredity, weight gain and occasionally hormonal imbalances. This imbalance may root from medications or substance use, liver or thyroid problems, or just a natural teen occurrence that may or may not go away on its own. Patients with gynecomastia may be embarrassed when their chests are exposed. A male breast reduction surgery can correct gynecomastia, and Dr. Crabtree can reshape the chest to a more masculine appearance.
