What Causes Enlarged Breasts in Men?

Changes in the chest are not something most men expect to deal with, and they are not often talked about. It’s understandable to have questions if you’ve noticed your chest looks or feels different.

Dr. York Yates, serving Layton and Salt Lake City, Utah, will explain the possible causes during your consultation. As a board-certified plastic surgeon, he’ll know if your case can be treated with male breast reduction.

Common Reasons Men Experience Enlarged Breasts (Gynecomastia)

Here is a closer look at the most common causes of enlarged breasts in men:

Hormonal Imbalances

The most frequent causes of enlarged breasts in men is a hormonal imbalance between estrogen and testosterone or an abnormal breast tissue response to normal hormonal levels. While men produce some estrogen, too much can stimulate breast tissue growth. 

Hormonal changes can happen naturally during puberty, aging, or in response to certain medical conditions.

Puberty-Related Gynecomastia

Many teenage boys experience temporary breast enlargement during puberty. This usually resolves on its own as hormone levels stabilize, but it can be concerning during those early years.

Weight Gain and Pseudogynecomastia

Extra weight can make your breasts look enlarged because of fat accumulation in the chest area. This condition, known as pseudogynecomastia, is different from true gynecomastia, which involves glandular tissue. Weight loss may reduce the size of the chest for some men, but not in all cases.

Medications and Substances

Certain medications and substances have been linked to male breast enlargement. These include some anti-androgens, anabolic steroids, certain antidepressants, and drugs used to treat ulcers and heart conditions. Alcohol and recreational drugs have also been associated with breast tissue growth in men. 

Medical Conditions and Aging

Health conditions such as liver disease, kidney disease, or tumors can also cause hormonal changes that lead to gynecomastia. Additionally, as men age, hormone levels shift, and this can result in changes to the chest.

When to Talk to a Surgeon
