Yes, gynecomastia is more common in obese individuals. This is because excess body fat can lead to hormonal imbalances that can cause the development of breast tissue in men. Fat cells contain an enzyme called aromatase, which can convert testosterone into estrogen. When estrogen levels in men become too high, it can lead to gynecomastia. In addition, obesity is also associated with other medical conditions that can contribute to gynecomastia, such as hypogonadism or liver disease. However, gynecomastia can also occur in individuals who are not obese, and may be caused by other factors such as medication use or hormonal imbalances.
