The duration of this condition can vary depending on several factors such as the age at which it occurs, the cause of the condition, and the severity of the enlargement. In most cases, gynecomastia caused by hormone changes during puberty will go away on its own within six months to two years. However, if a medication or medical condition is causing gynecomastia, the duration may vary. For example, if the cause is a medication, stopping the medication may resolve the issue. When gynecomastia is caused by genetic factors or fat, the condition does not go away. The treatment modalities include liposuction, Kybella injections, as well as surgical excision of the breast tissue. If gynecomastia is because of medical hormone issues, the underlying cause needs to be addressed medically. Some men may benefit from medication or hormone therapy, while others may also require surgery to remove the excess breast tissue through liposuction or excision. Kybella injections which dissolve fat may also be useful in patients who want to avoid surgery. The choice of treatment will depend on the underlying cause and the severity of the condition.
