Unilateral Gynecomastia: Understanding and Treating “One-Sided” Gynecomastia

Gynecomastia is a condition in men characterized by the development of breast tissue, creating a female-like appearance. This condition arises due to an imbalance between the sex hormones estrogen and testosterone. While gynecomastia is benign and doesn’t pose any direct physical threat, it can have a significant negative impact on a man’s mental health. Seeking treatment, often in the form of gynecomastia surgery, can be crucial for those affected. Though gynecomastia typically manifests as bilateral (affecting both breasts), a smaller percentage of men experience unilateral gynecomastia—where only one breast is enlarged—making it more challenging to cope with.

What is Unilateral Gynecomastia and Why Does It Occur?

Unilateral gynecomastia refers to the enlargement of breast tissue on only one side of the chest. While any form of gynecomastia can be difficult to live with, one-sided gynecomastia tends to cause even more psychological discomfort due to the noticeable asymmetry. Men with this condition often feel self-conscious, avoiding activities like swimming, exercising, and intimate situations where they might have to remove their shirts.

Interestingly, unilateral gynecomastia is more likely to occur on the left side of the chest, though experts are still uncertain why this is the case. The condition may or may not be accompanied by tenderness in the affected area. The causes of unilateral gynecomastia are generally similar to those of bilateral gynecomastia, including:

• Hormonal Imbalances: An imbalance between estrogen and testosterone levels can lead to the development of breast tissue. This imbalance typically affects both breasts but can sometimes result in growth on just one side.
• Medications: Certain medications, such as those used to treat prostate issues, heart conditions, or psychiatric disorders, can cause gynecomastia as a side effect, sometimes affecting only one breast.
• Underlying Health Conditions: Conditions like liver disease, kidney disease, or hormone-related tumors can lead to the development of unilateral gynecomastia.
• Puberty: Hormonal fluctuations during puberty can cause temporary gynecomastia, which may affect just one side of the chest.
• Weight Fluctuations: Significant changes in weight can lead to uneven fat distribution, potentially resulting in unilateral gynecomastia.

Diagnosing Unilateral Gynecomastia
If you notice uneven breast growth, it’s important to consult a healthcare professional for a proper diagnosis. In some instances, what appears to be unilateral gynecomastia could actually be a benign or malignant tumor. Your doctor may recommend imaging tests, such as an ultrasound or mammogram, to rule out other conditions and confirm the presence of gynecomastia.

Treatment Options for Unilateral Gynecomastia
For men dealing with unilateral gynecomastia, surgery is often the most effective treatment. Many individuals seek gynecomastia surgery in Mumbai to restore chest symmetry and regain confidence. The surgical procedure usually involves removing excess glandular tissue, fat, or both, to create a flatter, more balanced chest appearance.

What to Expect from Surgery
If you’re considering gynecomastia surgery in Mumbai, here’s what you can generally expect:

• Consultation: Your surgeon will evaluate your condition, discuss your goals, and determine the most appropriate surgical approach. They will also address any underlying causes of your gynecomastia to ensure comprehensive treatment.
• Procedure: The surgery, typically performed under general anesthesia, lasts about 1-2 hours. The surgeon will make small incisions around the areola or in other discreet areas to remove the excess tissue. We at LaserCosmesis like to keep the incisions hidden in the arm pits and around areola so that they are not easily spotted.
• Recovery: Post-surgery, you’ll be required to wear a compression garment to support healing and minimize swelling. Recovery times vary, but most patients can resume normal activities within a few weeks.

Emotional Impact of Unilateral Gynecomastia
Unilateral gynecomastia affects more than just physical appearance—it also takes a toll on emotional well-being. The noticeable chest asymmetry can lead to feelings of embarrassment and cause men to avoid situations where they might need to expose their chest, such as swimming or intimate encounters.

It’s essential to remember that you’re not alone, and effective treatments are available. Whether through lifestyle changes, medical management, or surgery, addressing unilateral gynecomastia can significantly improve both physical appearance and quality of life.

Unilateral gynecomastia can cause considerable physical and emotional distress, but it’s important to know that help is available. If you’re struggling with one-sided gynecomastia, consider consulting a specialist in gynecomastia surgery in Mumbai to explore your treatment options. By taking proactive steps, you can achieve a more balanced appearance and regain your self-confidence.

The most important point to remember is that the doctor may advise you to get both sites treated. It is possible for the patient to miss a small enlargement of the other side by labeling that less enlarged side as normal. But for optimal contouring and long-term sustainable results, it is better to go for both sides simultaneously. Only when both sides are equalized, further changes with weight fluctuations can still keep the chest looking symmetrical.
