What is Gynacomastia

Gynaecomastia is the enlargement of the gland tissue of the male breast. Newborns, boys going through puberty and middle-aged to older men are more prone to developing gynaecomastia as a result of normal changes in hormonal levels. Gynaecomastia is not a serious medical condition and may dissipate on its own.

Causes of the condition

This condition results from an imbalance of hormone levels in which there is a decrease in the amount of testosterone compared with oestrogen (female hormones). This could be cause by side effects of certain medications, natural hormone changes and certain medical conditions.

Surgery is seldom needed; however, please consult your doctor if you are concerned.
