Why Men Develop Gynecomastia

Most men strive to have a defined pectoral appearance, and the development of a fatty chest can lead to extreme embarrassment. Gynecomastia is a medical condition where men develop excess glandular breast tissue directly under the nipple. Gynecomastia is usually non-cancerous and caused by an imbalance of hormones.

Understanding the cause of your gynecomastia will allow you to better prevent its return.

Hormonal Causes

Men who develop gynecomastia may have high levels of estrogen in their system. Gynecomastia can be indicative of an underlying medical condition such as a tumor of the adrenal, testes, or pituitary glands. It may also be a side effect of hyperthyroidism, hypogonadism, kidney disease, or liver failure. It is important to seek medical help to rule out any medical causes of your gynecomastia.

Medication used to treat some illnesses may cause gynecomastia to develop. Common medications include:

  • AIDS medication
  • Anti-anxiety medication
  • Chemotherapy
  • Tricyclic antidepressants
  • Ulcer medication

Drugs and Alcohol

Illegal drug use and alcohol abuse can lead to the development of gynecomastia. Anabolic steroids, amphetamines, heroin, and marijuana are all known to cause gynecomastia. It is important to recognise if drugs or alcohol are the root cause because continual use after correction surgery can lead to the redevelopment of gynecomastia.  


Pseudogynecomastia occurs when you have a fatty breast appearance without the presence of excess glandular tissue. This typically occurs in men who are overweight or at an older age. Fatty tissue may accumulate around the nipple because of poor diet, lack of exercise, or a natural slowing of your metabolism. Pseudogynecomastia is easily treated using liposuction. In some cases, excision may be used.

Gynecomastia Surgery

Gynecomastia surgery is designed to improve the contour of the male chest to restore a more masculine chest appearance. Small incisions are created along the natural contours of the chest, and glandular tissue is excised from under the skin.
