Introduction

Noticing that only one side of your chest looks enlarged or puffy? You’re not alone. Unilateral gynecomastia is a common, often misunderstood condition in which breast tissue grows on only one side, causing visible chest asymmetry and emotional discomfort.

It may involve glandular tissue, fat, or both. Many men mistake it for muscle imbalance or old injury—but unlike those, unilateral gynecomastia doesn’t improve with exercise alone. Result: awkward proportions, dressing frustrations, and social hesitation.

The good news: it’s fully treatable. At Allure Medspa, Mumbai, Dr. Milan Doshi restores symmetry with customized gland removal and liposuction—typically as a safe day-care procedure.

What Is Unilateral Gynecomastia?

Male breast enlargement on only one side (left or right)
May involve gland, fat, or a combination
Often confused with chest muscle imbalance or injury
Commonly noticed during self-exam or while dressing

Why Does It Affect Only One Side?

Different estrogen sensitivity between right and left glands
Past trauma or injections on one side may trigger growth
Certain medications can influence one breast more than the other
Idiopathic (no identifiable cause) in many cases

How to Identify Unilateral Gynecomastia

Only a qualified plastic surgeon can distinguish true gland from fat or muscle differences. Indicators include:

Firm tissue directly behind one nipple/areola (not soft fat)
Puffy areola or projection on one side
Ultrasound to confirm gland presence
Hormonal blood tests if an endocrine issue is suspected

Can Exercise Fix Unilateral Gynecomastia?

No. Exercise can build pectoral muscle but won’t remove gland.
Targeted workouts can’t shrink gland; they may accentuate asymmetry.
Definitive correction requires surgical gland removal (with/without liposuction).

Treatment Options for Unilateral Gynecomastia

A personalized surgical plan removes excess gland and/or fat while sculpting both sides evenly:

Keyhole periareolar incision to excise gland on the affected side
Liposuction if fat is present (for smooth contour)
Local anesthesia with sedation (day-care procedure; no overnight stay)
Compression garment post-surgery to support healing
