Gynecomastia cannot always be prevented, but there are some steps that can be taken to reduce the risk. Avoiding the use of certain medications that can cause hormonal imbalances, such as anabolic steroids or medications for prostate cancer, may help. Maintaining a healthy weight and lifestyle, including regular exercise and a balanced diet, may also reduce the risk of developing gynecomastia. In addition, seeking treatment for underlying medical conditions, such as liver or kidney disease, may help prevent the condition from developing. However, since gynecomastia can also be caused by natural hormonal changes during puberty or aging, it may not always be preventable.
