The Mayo Clinic defines gynecomastia as swelling of the breast tissue in boys or men caused by an imbalance of estrogen and testosterone. Gynecomastia can develop in newborns, pubescent boys or older men as a result of a change in hormone levels. It is not a major health hazard, but people with gynecomastia may suffer from breast pain and social embarrassment.
According to Medicine Net, gynecomastia can also be a side effect of pharmaceutical medications or illegal drugs. It is also associated with hyperthyroidism, chronic kidney failure and cirrhosis of the liver. Malnutrition can also create a hormonal change that causes gynecomastia. Disorders of the testes can result in decreased testosterone and high estrogen levels. Testicular cancers or genetic disorders such as Klinefelter's syndrome can also cause a hormonal imbalance.
