Liver Disease
You might be wondering what the connection between a liver disease [5] and Gynecomastia is. It is important to know the role your liver plays in your breast tissue. The work of the liver is to break down and get rid of excess estrogen. But your liver may be unable to perform its function effectively, if it is inflamed, fatty or diseased, thereby allowing the build up of estrogen in your system. If you consume a lot of carbs and alcohol, it might affect your hormonal balance and cause your breast to grow.
Kidney Failure
Kidney failure is a severe health condition that can lead to hormonal imbalances. Unfortunately, it is common amongst men who are experiencing chronic kidney disease to also have low testosterone. And about 50% of men undergoing dialysis treatment also show signs of gynecomastia.
