In some cases, gynecomastia is reversible, particularly if it is caused by
temporary hormonal imbalances during puberty or due to medication side effects. In these cases, the breast tissue may shrink and disappear on its own once the hormonal imbalance or medication use is resolved. However, in more severe or persistent cases, the breast tissue may not go away on its own and may require medical intervention, such as medication or surgery. Therefore, it is important for anyone with gynecomastia to seek medical evaluation to determine the underlying cause and to discuss appropriate treatment options.
