What gynaecomastia is
Gynaecomastia is enlargement of glandular breast tissue in men. It is genuinely common: it affects a large proportion of adolescent boys, most of whom resolve without treatment, and it appears again in a significant number of men in middle and later life.
It is worth distinguishing true gynaecomastia, where firm glandular tissue sits behind the nipple, from pseudogynaecomastia, where the fullness is fat alone. Most patients have a mixture of both, which is why the operation usually combines two techniques.
Why it happens
Common contributors include normal hormonal changes at puberty and with age, being overweight, certain medications (including some used for prostate conditions, blood pressure, depression and reflux), anabolic steroid use, and alcohol or recreational drug use. Less commonly it is caused by liver, kidney, thyroid or testicular disease.
This matters clinically. Before offering surgery, Dr Kueh will take a history and, where indicated, arrange investigation to rule out an underlying cause. Some cases resolve when a contributing medication is changed. Sudden, one-sided or painful enlargement always warrants assessment, since male breast cancer, though uncommon, does occur.
How surgery is done
The approach depends on what your chest is actually made of.
Liposuction alone
Where the fullness is predominantly fat with little glandular tissue, liposuction through two or three tiny incisions may be enough.
Gland excision with liposuction
The most common approach. Firm glandular tissue is removed through a small incision along the lower border of the areola, where the scar blends into the colour change. Liposuction then blends the surrounding contour so there is no crater or step.
With skin excision
Where there is substantial excess skin — typically after major weight loss or in longstanding severe cases — skin must be removed as well. This gives a flatter chest but leaves longer scars, and the trade-off is discussed carefully beforehand.
Who it may suit
- Men whose gynaecomastia has been stable for at least a year
- Men in whom an underlying medical or drug cause has been excluded or addressed
- Men at a stable weight, since weight change alters the result
- Non-smokers in good general health
Who it may not suit
- Adolescents whose gynaecomastia is recent — many resolve on their own, and surgery is usually deferred
- Men currently using anabolic steroids, unless they stop
- Men with a treatable underlying cause that has not yet been managed
- Men still actively losing weight
What recovery involves
Recovery is generally quicker than patients expect. A compression vest is worn for four to six weeks to control swelling and help the skin settle onto the new contour. Most men return to desk work within three to seven days.
Chest and upper-body exercise is avoided for around four to six weeks. Bruising and swelling are normal for the first few weeks; the chest often feels firm and numb initially, and sensation returns gradually. The final contour is usually clear at three to six months.
Risks and limitations
Risks include bleeding, haematoma (the most common early complication after gland excision), infection, altered or reduced nipple sensation, and visible or thickened scars.
Contour problems are the most relevant aesthetic risk: removing too much tissue directly under the nipple can leave a saucer-shaped depression, while removing too little leaves residual fullness. Some asymmetry between the two sides is common, because the two sides usually differ to begin with. Loose skin may remain if skin elasticity is poor. Occasionally a second, smaller procedure is needed to refine the result.
Gynaecomastia can recur if the underlying cause returns — resuming steroids, significant weight gain, or restarting a contributing medication.

Gynaecomastia FAQ
Will gynaecomastia go away without surgery?
Often, in adolescents. Puberty-related gynaecomastia commonly resolves on its own within one to two years, which is why surgery is usually deferred in younger patients.
In adults, gynaecomastia that has been present and stable for more than a year rarely resolves by itself, though it may improve if a contributing medication or cause is addressed.
Can exercise or weight loss fix it?
Weight loss reduces the fatty component and is always worth doing first. It does not remove glandular tissue, which is firm and sits directly behind the nipple. Men who lose significant weight often find a firm disc of tissue remains, and that part requires surgery.
Do I need tests before surgery?
Sometimes. Dr Kueh will take a full history, including medications and supplements, and examine you. Blood tests or imaging may be arranged if there is any suggestion of a hormonal, liver, kidney, thyroid or testicular cause, or if the enlargement is one-sided, recent, painful or unusual in character.
How visible are the scars?
In most cases the incision follows the lower border of the areola, where the natural colour change helps disguise it. Liposuction incisions are only a few millimetres. Where skin has to be removed, scars are longer and more visible, and that trade-off is discussed in detail before you decide.
Is gynaecomastia surgery covered by insurance?
Sometimes, where there is a documented medical indication such as pain, or a diagnosed underlying condition. Surgery undertaken for appearance alone is usually treated as cosmetic and not covered. Our team can provide the documentation your insurer needs so you can check your policy before proceeding.
Can it come back after surgery?
Glandular tissue that has been removed does not regrow. However, gynaecomastia can recur if the original cause returns — resuming anabolic steroids, significant weight gain, or restarting a medication that contributed to it.
