Condition
Gynaecomastia
Reviewed by Dr Abhishek Kumar on
Gynaecomastia is the enlargement of the glandular tissue in a man's breast, caused by an imbalance between oestrogen and testosterone acting on that tissue, and is not the same as the fatty enlargement seen with weight gain. It commonly appears in newborn boys, again during puberty, and again in older age, and in most of these settings it settles by itself without treatment.
Gynaecomastia is common rather than rare: it affects a large share of boys passing through puberty and, by some estimates, a comparable share of men in their 50s to 80s, most often as a normal swing in the oestrogen-to-testosterone ratio rather than a sign of disease[1]. A smaller group of cases is caused by a medicine — spironolactone, certain ulcer and psychiatric drugs, 5-alpha-reductase inhibitors used for hair loss or an enlarged prostate, and anabolic steroids are among the more familiar culprits — or by an underlying condition such as reduced testosterone production, liver or kidney disease, or, rarely, a hormone-secreting tumour[2]. Because the same swelling can come from very different causes, the point of a consultation is working out which one applies before deciding whether to simply watch, change a medicine, or refer for further tests.
Some symptoms need prompt care: when to seek emergency or specialist care.
How each system of medicine approaches Gynaecomastia
| System | Approach | Typical review period | |
|---|---|---|---|
| Modern medicine | Assessment starts by distinguishing true glandular breast tissue from fatty tissue, followed by a review of medicines, supplements and relevant medical history. Blood tests such as testosterone, oestradiol, prolactin, thyroid, liver and kidney function may be considered when the history or examination suggests an underlying cause[2]. | Pubertal gynaecomastia is typically watched for 12-24 months, since most cases resolve in that window; tissue that is still present and firm after about a year has usually turned fibrous, and medicine at that stage rarely shrinks it[2]. |
Supported by clinical evidence
Assessment and management are informed by established clinical reviews covering the evaluation and management of gynaecomastia. |
Modern medicine for Gynaecomastia
Where a cause is found and reversible — stopping or switching an implicated drug, treating an underlying hormonal or organ problem — tissue that is still soft and recently formed often regresses by itself once the trigger is removed[1].
- Puberty is the most common trigger: a large share of boys develop some breast tissue during puberty as oestrogen and testosterone rise at different rates, and many cases resolve without treatment within a couple of years[1].
- Drugs are a recognised, sometimes reversible cause: medicines such as spironolactone and some other commonly used drugs, as well as anabolic steroids, can contribute to gynaecomastia. When an implicated medicine is identified, the prescriber may consider whether it can safely be changed or stopped[2].
- Established glandular tissue may not regress with medicines: treatment depends on the duration, cause and severity. When longstanding gynaecomastia persists and causes significant symptoms or concern, surgical treatment may be considered. Evidence does not support herbal or homeopathic remedies as established treatments for established gynaecomastia[2].

What is known and what remains uncertain
- Known: Gynaecomastia is common at birth, in puberty and in older age, and most cases resolve without treatment.
- Known: Several common medicines are recognised, reversible causes of gynaecomastia.
- Uncertain: No published evidence shows that a herbal or homeopathic remedy shrinks established glandular tissue.
- Uncertain: Exactly when tissue turns fibrous varies between individuals beyond the general one-year guide.
Questions to ask your doctor
- Is this glandular tissue or a fatty chest?
- Could one of my medicines be causing this?
- Do I need blood tests to check my hormones or organ function?
- Is this likely to resolve on its own, and how long should I wait?
- If it does not resolve, what treatment options are there?

Frequently Asked Questions
Is gynaecomastia the same as a fat chest from weight gain?
No. A fatty chest is soft fat spread evenly under the skin, while gynaecomastia is a firmer disc of glandular tissue a doctor can usually feel directly under the nipple; the two can also occur together.
Will it go away by itself?
Often, yes, especially in newborns and teenagers, where most cases settle within a couple of years as hormone levels even out[1]. Tissue still present after about a year, or that appeared in adulthood, is worth a proper assessment.
Which medicines can cause it?
Several common ones can, including spironolactone, certain ulcer and psychiatric medicines, prostate and hair-loss drugs, and anabolic steroids[2].
Can Ayurveda or homeopathy shrink the swelling?
There is no published evidence that any Ayurvedic or homeopathic remedy shrinks established glandular tissue, so this page offers only the modern-medicine route for gynaecomastia, and a consultation in any system leads to the same referral.
When is surgery needed?
When the swelling has been present long enough to turn fibrous, usually after roughly a year, or when it persists after every reversible cause has been addressed; at that point medicine no longer shrinks it and removing the tissue is the option that works[2].
