Gynecomastia & Alcohol
Gynecomastia can be caused by a hormonal imbalance in men. This condition causes breast tissue to develop in men when too little testosterone is produced in conjunction with increased estrogen levels (there are many causes of Gynecomastia, it is important to see your doctor if you suspect that you may have it). While Gynecomastia has may possible causes, alcohol may exacerbate the condition.
Excessive alcohol use decreases testosterone production in men (sometimes dramatically). This can allow estrogen levels to rise therefore leading to the development of breast tissue in men. As alcohol is consumed testosterone levels diminish in the blood stream. This may last for as long as twelve to twenty hours after having had your last drink.
Alcohol abuse may cause testicular damage, including erectile dysfunction and loss of desire. Essentially alcohol is bad for testosterone production. A glass of wine now and then may be good for your heart and likely won't have any lasting impact on your testosterone levels. Drinking a twelve pack of beer every night is probably not a wise decision and may keep your body in a permanent state of diminished testosterone production.
Drinking heavily over a long period of time may put your body into a permanent condition whereby it produces low levels of testosterone. By doing this you allow estrogen levels to rise thereby increasing the chances that Gynecomastia may develop. It would probably be a wise decision to limit your alcohol intake if you have Gynecomastia.
If you suspect that you may have Gynecomastia please consult your doctor. There are other underlying medical conditions that may cause Gynecomastia including cirrhosis of the liver and various medications. It's important to be honest with your doctor about your alcohol intake, including any drugs or medications that you may be on. If you have a problem regulating your alcohol intake there is help available. Alcoholics Anonymous is a good place to start.
