What is Gynecomastia?

Sometimes, hormonal changes during puberty can cause temporary bouts of gyno. Similarly, infants can be born with breasts due to their mother’s high estrogen levels (these cases of gyno are usually temporary). Men can also experience gyno as they reach middle age and experience a decline in testosterone production. Unfortunately, this kind of gynecomastia is not usually temporary, since the proper hormonal balance is not likely to return.
Other natural causes can include:

• Hypogonadism – this is a condition where the testes do not produce enough testosterone.
• Cancerous tumors – testicular cancer, adrenal cancer, or cancer of the pituitary gland can cause hormonal changes in the body that present themselves in a wide variety of symptoms, including breast enlargement.
• Hyperthyroidism – the thyroid gland is responsible for a hormone called thyroxine. A drastic increase in this hormone can cause gyno as a result.
• Kidney failure – hormonal changes as a result of improperly functioning kidneys can cause this symptom to manifest.
• Liver failure – hormonal changes due to liver problems can cause gyno, as can some of the medications (particularly for cirrhosis of the liver).
• Poor diet – if your body is starved of nutrition, the testosterone levels will decrease, but the estrogen levels remain the same. This imbalance can cause gyno. Interestingly, gyno can also occur as a result of switching back to a regular, healthy diet.
