Top Causes of Gynecomastia

Posted May 19, 2017 in Blog, Gynecomastia Surgery

A masculine, confident appearance can be rooted in the physique for many men. If you have a softer chest appearance that has begun to take on a more feminine, breast-like shape, you may be suffering from gynecomastia or pseudogynecomastia. The appearance of male breasts can be the result of glandular tissue development under the areolas or excess fat accumulation that creates a puffy chest appearance.

Gynecomastia Patient by Dr. Taylor

Your enlarged male breasts may leave you feeling embarrassed about the look of your body, leading you to withdraw from many social activities you once loved. Gynecomastia in some form is common in about 15 percent of men, and it can develop for a number of reasons. It can also be corrected easily.

Causes of Male Breast Formation

Mild and severe forms of male breast formation, whether it be gynecomastia or pseudogynecomastia, are treatable. However, understanding the root of your breast tissue development may prevent future issues from forming.


When men have estrogen levels that surpass the normal range, it can stimulate glandular tissue development. 70 percent of boys will find they gain a mild form of gynecomastia during puberty, which can resolve itself naturally. Issues arrive when gynecomastia is present in older men because it can be indicative of an underlying medical condition that is causing the body to produce too much estrogen.


Medications that treat a number of illnesses can cause gynecomastia as a side effect. The effects of these medications can be more pronounced in middle-aged or older men. The following medications may result in glandular tissue development, and you should discuss the side effects with your physician.

  • Antibiotics
  • Heart medications
  • Anti-anxiety drugs
  • Tricyclic antidepressants
  • Chemotherapy
  • Some heartburn drugs

Drug Abuse

While harder drugs like heroin can cause gynecomastia, marijuana users tend to have higher rates of male breast formation. Additionally, people who abuse amphetamines and steroids are at a greater risk. This is because drugs can affect the natural release of chemicals in your body, resulting in an underproduction of testosterone or an overproduction of estrogen.

Lifestyle Factors

Pseudogynecomastia is often the result of poor lifestyle choices that lead to men being overweight or obese. Pseudogynecomastia is marked by a breast-like appearance that is caused by fat accumulation under the areolas. It can often be treated through proper diet and exercise; however, stubborn deposits that require correction may still remain.

Treating Gynecomastia

Dr. Taylor believes that every man should be confident in his appearance. Having a more defined, masculine chest contour may help you feel more comfortable with your body. Male breast reduction surgery uses a combination of excision and liposuction techniques to remove glandular tissue and excess fat. During fat removal, the shape of your chest can become more defined, and you can achieve more attractive body proportions.
