Gynecomastia is the enlargement of glandular breast tissue in males caused by an imbalance between oestrogen and testosterone. It is more common than most men expect affecting over 50 percent of males at some point in their lives. The cause determines the treatment. This blog covers what triggers the hormonal shift, which medications and lifestyle factors contribute, and when the condition needs medical or surgical attention.
Gynecomastia is not fat. It is glandular breast tissue and it forms for one reason: the balance between oestrogen and testosterone shifts. Every male body produces small amounts of oestrogen. When oestrogen rises relative to testosterone, or when testosterone drops, the breast tissue responds. Glandular tissue beneath the nipple begins to grow. It feels firm and disc-like under the areola. It does not respond to exercise or diet. The trigger for that hormonal shift varies widely which is why the same condition appears in newborns, teenagers, middle-aged men, and elderly patients.
According to Dr Harikiran Chekuri, one of India’s pioneering plastic surgeons, “The most important thing to understand about gynecomastia is that it is a hormonal condition, not a fat problem. That distinction determines everything whether the cause can be addressed without surgery, whether the condition will self-resolve, and whether surgery is actually the right answer. Getting the cause right is step one.”
What Are the Main Causes of Gynecomastia?
The trigger is almost always a relative excess of oestrogen over testosterone. The reason for that imbalance differs by age and circumstance.
Puberty and ageing: The two most common natural causes. Pubertal fluctuations in testosterone and oestrogen cause temporary glandular growth over 90 percent resolves within 24 months. In older men, declining testosterone combined with increased body fat creates the same hormonal imbalance.
Anabolic steroids and performance drugs: A leading cause in young adult men. Steroids suppress natural testosterone. When a cycle ends, oestrogen remains proportionally elevated and glandular tissue develops. Established glandular tissue rarely resolves without gynecomastia surgery.
Medications: A frequently missed cause. Spironolactone, anti-androgens, some antidepressants, proton pump inhibitors, and certain heart medications all carry gynecomastia as a known side effect. Flag any chest change after starting a new medication with your prescribing doctor before assuming surgery is needed.
Underlying medical conditions: Hypogonadism, hyperthyroidism, liver disease, and kidney failure all alter hormone levels in ways that favour glandular growth. Adrenal or testicular tumours are rare but must be ruled out when the cause is not obvious.
Obesity and pseudogynecomastia: Excess fat produces oestrogen through aromatisation. This drives pseudogynecomastia chest enlargement that is fat, not glandular tissue. Pseudogynecomastia responds to weight loss. True gynecomastia does not. Clinical palpation and ultrasound tell them apart.
What to tell your doctor: How long the chest change has been present, any medications or supplements started recently, steroid use, and whether there is pain or nipple discharge. Glandular tissue present for over 18 months is unlikely to resolve without surgery as it fibroses over time.
Patients who have confirmed gynecomastia and want to understand what determines surgical eligibility should read Who Is Eligible for Gynecomastia Surgery? for a full breakdown of the candidacy criteria before booking a consultation.
When Does Gynecomastia Need Treatment and What Are the Options?
Not every case needs surgery. The cause and duration determine the right response.
- When it resolves on its own: Pubertal gynecomastia resolves in the majority of cases within 24 months. Drug-induced gynecomastia may resolve once the offending medication is stopped under physician supervision.
- When medical management helps: Treating an identified hormonal condition such as hypogonadism or hyperthyroidism may reduce the glandular stimulus. Medications including tamoxifen have some evidence of benefit in early-stage cases. Once tissue fibroses, medication does not reverse it.
- When surgery is the answer: Gynecomastia present for over 18 months, not responding to conservative measures, or causing significant distress requires surgical correction. Exercise and diet do not remove glandular tissue. Surgery is the only effective option for established cases. For patients who lost significant weight and still have chest fullness, read How Is the Male Chest Contoured After Weight Loss? for a breakdown of what remains after fat loss and what surgery addresses.
- What to tell your surgeon: Full medication and supplement history, duration of the condition, and any previous investigations. A surgeon who skips this and moves directly to booking surgery is not conducting an appropriate assessment.

Frequently Asked Questions
What is the main cause of gynecomastia in males?
A hormonal imbalance where oestrogen is elevated relative to testosterone. This can be caused by puberty, ageing, anabolic steroids, certain medications, or underlying medical conditions.
Does gynecomastia go away on its own?
Pubertal gynecomastia resolves in over 90 percent of cases within 24 months. Adult gynecomastia present for more than 18 months is unlikely to resolve without treatment as the tissue fibroses.
Can exercise reduce gynecomastia?
Exercise reduces chest fat but cannot remove glandular tissue. Surgery is the only effective treatment for established glandular gynecomastia.
Which medications cause gynecomastia?
Spironolactone, anti-androgens, some antidepressants, proton pump inhibitors, anabolic steroids, and certain heart medications are among the most common.
Is gynecomastia the same as chest fat?
No. Gynecomastia is glandular breast tissue. Chest fat is pseudogynecomastia. Both can coexist. Clinical palpation and ultrasound confirm which is which.
