Gynecomastia (Gynaecomastia) is an abnormal enlargement of breasts in men due to a hormonal imbalance between estrogen and testosterone. The condition affects one or both breasts, sometimes asymmetrically. Nearly 30%-60% of men suffer from this.
The most common cause of man boobs is transient estrogen (female hormone) surge during puberty (11-14 years), which goes away without treatment. A few men have persistent chest enlargements that require surgical correction. The enlarged breast tissue is neither cancerous nor dangerous. The effects of certain drugs and medical conditions may also cause gynecomastia, so it is essential to address these conditions prior to having a gynecomastia surgery. There are very few men who experience pain in their enlarged breasts, which is known as 'PAINFUL GYNECOMASTIA'. Male breast enlargement cannot be treated with diet and exercise alone.
Gynecomastia leads to extreme embarrassment and loss of self-confidence. Though it's not a serious health concern, many teens suffer from low self-esteem and body shaming.
