What Is Gynecomastia?
Gynecomastia is the benign enlargement of male breast tissue, which can occur on one or both sides of the chest. The composition of this tissue varies from person to person and typically consists of either soft fatty tissue, firmer breast glandular tissue, or a combination of both.
In some cases, the glandular tissue may feel tender, and the areola (the dark area around the nipple) may expand or project forward. When the condition presents primarily as "puffy nipples," it can still cause noticeable physical and psychological discomfort.
Types of Gynecomastia
| Type | Clinical Description | Path pathway |
| Physiological | Arises from natural hormonal fluctuations during milestones like infancy, puberty, or older adulthood. | Often resolves naturally within months or a few years; surgery is considered if it persists well into adulthood. |
| Pathological | Triggered by an underlying medical condition, such as thyroid dysfunction, liver or kidney disease, or hormone-producing tumors. | Requires a thorough medical investigation to treat the root cause before any local chest surgery can be planned. |
| Idiopathic | The most common adult presentation, where tissue enlargement occurs gradually over time with no identifiable medical or hormonal trigger. | Diagnosed after ruling out other conditions; managed directly via surgical contouring based on the patient's anatomy. |
What Causes Gynecomastia?
True gynecomastia is driven by a shift in the balance between the hormones testosterone and estrogen. When estrogen levels are relatively high, the glandular tissue responds by expanding. This frequently happens during natural life transitions:
- At Birth: Increased maternal oestrogen may temporarily cause breast tissue enlargement, usually resolving within weeks.
- During Puberty: Hormonal changes between ages 10 and 20 can cause persistent breast tissue growth, leading to psychological distress.
- Older Adulthood: Reduced testosterone levels after age 50 may contribute to chest wall enlargement.
Conversely, pseudogynecomastia is primarily linked to body weight, diet, and lifestyle, where fat cells naturally cluster over the pectoral muscles without gland development.
Certain external factors can trigger or worsen both true and pseudogynecomastia. These include the long-term use of anabolic steroids, specific antidepressants, heart medications, anti-anxiety remedies, regular alcohol consumption, and certain antibiotics.
Consultation and Planning
An in-depth discussion will be conducted during the initial consultation to understand your general health and the symptoms associated with gynecomastia, followed by a thorough examination and evaluation of the size, volume and nature of the gynecomastia.
A key objective of the consultation is to determine whether the breast enlargement is due to fatty tissue (pseudogynecomastia), true glandular tissue, or a combination, as this directly influences the surgical approach and Medisave and insurance eligibility.
For local patients, a minimum one-week cooling period is required between the initial consultation and any elective surgical procedure, in accordance with MOH guidelines. This gives every patient time to consider the options and arrive at a decision without pressure.

During this visit, 3D pictures using the Quantificare 3D camera will be taken to aid with the evaluation and discussion.
Following this, blood tests will be arranged to assess hormone levels, and an ultrasound may be performed to rule out any suspicious lesions. Bringing prior scans, reports, or blood tests is recommended.
The Gynecomastia Surgery Procedure
Gynecomastia surgery is typically performed under general anaesthesia, either as a day surgery or an overnight stay. Incisions are carefully placed around the areola to ensure scars are well-camouflaged. The procedure often involves:
- Liposuction: To remove excess fatty tissue.
- Excision of Breast Gland: To remove firmer glandular tissue.
- Combination Approach: Where both fatty and glandular tissues are present, liposuction and excision are performed together to address the chest contour in a single procedure.
Non-surgical methods are limited for glandular tissue. True glandular tissue is dense and fibrous; it cannot be dissolved by exercise, weight loss, or non-invasive fat-freezing treatments. While non-surgical external lipolysis (fat breakdown treatments) may slightly reduce pure fat deposits in pseudogynecomastia, the outcomes are highly variable and temporary, making surgery the definitive choice for lasting results.
Recovery After Gynecomastia Surgery
Recovery generally spans about two weeks, with most patients returning to normal life in stages. A typical recovery timeline:
- First Few Days: Discomfort, swelling, and bruising are typical and managed with prescribed pain medication. If drains were placed during surgery, these are typically removed the following day.
- Day Two to Three Onwards: Light daily activities can usually resume, with most patients returning to desk-based work within this period.
- First Six Weeks: A compression garment is typically worn over the chest for around six weeks to support healing and reduce swelling, while upper-body workouts and sports are avoided during this period.
- Around Three Months: The swelling has largely settled by this point, and the final chest contour becomes apparent.
Regular follow-up appointments are scheduled to monitor healing and answer any questions that come up in the early weeks of recovery.
