Causes of Gynecomastia

The exact causes of Gynecomastia have still not been pinpointed but doctors are able to specify some major factors that can bring on this condition.

Puberty
This is perhaps the most common occurence of gynecomastia. Adolescent males will often experience breast enlargement due to the fluctuation of their hormones during this time period. The breast enlargement is generally only temporary and doctors may advise a "wait and see" approach. This is because the breast tissue should recede once puberty nears its end. If the breast tissue is persistant after the age of 21, it may indicate a long-term condition.

Aging
Decreased production of male hormones will also play a part with this factor. If you are overweight, your probability of developing Gynecomastia will increase.

Obesity
Of course with weight gain, enlarged breasts will develop. The problem becomes most noticeable when the overweight person starts to lose the weight. The fat stored in the breast tissue becomes stubborn to burn off through exercise. It is after years of this frustration that people often begin to look for medical alternatives.

Breast Cancer
The onset of Gynecomastia can be a warning sign of problems with the breast tissue. Although male breast cancer is very rare, you should be examined by a doctor if you have the sudden formation of "man boobs" or excessive glandular swelling. A tumor could affect glands and would then produce more hormones.

Males with an XXY Chromosome
This factor can lead to the man producing excess female hormones such as estrogen. With these hormones in play, breasts may develop. Obviously this is a risk factor that is somewhat unavoidable.

Medications and Drugs
Steroid abuse and Marijuana use have been linked to Gynecomastia. Blood pressure medicines, hormones and other medications may also cause an increase in estrogen levels. This would contribute to "man boobs" as well.
