Gynaecomastia Surgery (Male Unilateral)

Gynaecomastia is a condition where too much breast tissue has developed. The condition can be severe and can affect one or both sides of your chest.

For most teenagers, gynaecomastia goes away as your hormone levels naturally get into balance. However, in some men the condition is permanent.
Gynaecomastia is not life-threatening but you may want to have the excess tissue removed if you feel embarrassed by the condition.

Your chest should have a more male appearance and both sides should look similar to each other.

If the condition is in its early stages, you may be able to take medication to prevent further growth.

If you are overweight and your gynaecomastia is caused mainly by fatty tissue, losing weight may lead to a reduction in the gynaecomastia.

The operation is usually performed under a general anaesthetic but various anaesthetic techniques are possible.

The operation usually takes 30 minutes to an hour for each side that needs to be treated.
If you have only a small amount of excess tissue and good skin elasticity, the operation may involve only liposuction. Your surgeon will use a cannula (thin, hollow tube) attached to a suction device to remove the fat through a small cut.

They will make one or two small cuts on a crease line on the inside or outside of your chest.

Your surgeon will move the cannula through the tissue, making it easier to suction out.

For severe gynaecomastia your surgeon will make a cut on the line around the areola. They will remove the excess tissue and skin.

You should be able to go home the same day if you had only liposuction, or the next day when any drains have been removed.

You should be able to return to work after a week, depending on your type of work.
Most men return to normal activities after 4 to 6 weeks.

The healthcare team will advise you on exercising to help keep you to a healthy weight and to improve the cosmetic result.

Your new chest shape will take several months to appear as the swelling reduces and your skin tightens.

Some complications can be serious and can even cause death.
