Gynecomastia, which is characterized by the enlargement of glandular tissue in the male chest, affects men of all ages, from puberty to late middle age. Understanding the causes of this condition is crucial in addressing and correcting it.

During puberty, gynecomastia is a common occurrence, with around 70% of teenage boys experiencing some degree of breast enlargement. For most of them, this is only temporary, with around 90% of cases resolving on their own within two years, without any treatment. While most pubertal cases are idiopathic, endocrine and chromosomal abnormalities should be identified when present.

Obesity is an increasingly common cause of large breast development in men. Young men developing symmetric, increasing breast enlargement after puberty, in the absence of obesity, may have it attributed to marijuana use, which can stimulate breast growth strongly. Alcohol has also been shown to lead to the development of gynecomastia.

Gynecomastia can also be caused by certain medications, such as anti-anxiety drugs, spironolactone, and steroids. Bodybuilders often try to reduce their risk of gynecomastia by using tamoxifen or aromatase inhibitors, which are so-called anti-estrogen medications. However, these treatments don't always work. I have seen and treated a significant number of "Puffy Nipples," a mild form of gynecomastia. When glandular tissue has developed, there is only one safe way to have it removed, and that is with surgery.

Additionally, genetics can play a role in determining a man's susceptibility to developing gynecomastia, as can underlying health conditions such as liver disease.
