Gynaecomastia, a condition that leads to the abnormal growth of the male breasts, is quite the common condition that can affect almost any man. In our latest article, Dr Gary Horn, a distinguished London and Norwich-based plastic surgeon, details the main known causes of the condition, and reveals how it is diagnosed.

What are the main known causes of gynaecomastia?

The main cause of gynaecomastia is a hormonal imbalance that occurs during puberty. Also, individuals such as bodybuilders who wish to and require to take some steroids, are putting themselves at high risk of developing gynaecomastia. Also, as men age, they are more at risk of developing another hormonal imbalance that can lead to gynaecomastia.


Who is most at risk?

Almost every man during puberty is at risk if they have a hormonal imbalance. 


How is it diagnosed?

The diagnosis of gynaecomastia, is, most of the time, clinical. When the patient comes for a medical check-up, the gland can be felt, and if the gland has become enlarged, a diagnosis of gynaecomastia can be made. It can also be confirmed with an ultrasound scan.


Finally, when it is necessary, patients can have a blood test to confirm whether or not they are suffering from a hormonal imbalance.


What is the prognosis?

Normally, once gynaecomastia has been diagnosed, it usually doesn’t change too much. If gynaecomastia is removed surgically, everything can get back to normal.


How is it treated most effectively?

The most effective treatment for gynaecomastia is surgical intervention, which is a combination of gland removal and a liposuction.
