Gynecomastia, also known as male breast enlargement, is a condition that causes the breast tissue in men to enlarge.

• Hormonal imbalance: Changes in hormone levels, such as an increase in estrogen or a decrease in testosterone, can lead to gynecomastia.
• Medication side effects: Certain medications, such as anabolic steroids, certain heart medications, and some antidepressants, can cause gynecomastia.
• Medical conditions: Certain medical conditions, such as liver disease, kidney failure, and hypogonadism, can also cause gynecomastia.
