causes of gynecomastia
mainly due to more production of estrogen in males
Hypogonadism. Any of the conditions that interfere with normal testosterone production, such as Klinefelter syndrome or pituitary insufficiency, can be associated with gynecomastia.
Aging. Hormone changes that occur with normal aging can cause gynecomastia, especially in men who are overweight.
Tumors. Some tumors, such as those involving the testes, adrenal glands or pituitary gland, can produce hormones that alter the male-female hormone balance.
Hyperthyroidism. In this condition, the thyroid gland produces too much of the hormone thyroxine.
Kidney failure. About half the people being treated with regular hemodialysis experience gynecomastia due to hormonal changes.
Liver failure and cirrhosis. Hormonal fluctuations related to liver problems as well as medications taken for cirrhosis are associated with gynecomastia.
Malnutrition and starvation. When your body is deprived of adequate nutrition, testosterone levels drop, but estrogen levels remain constant, causing a hormonal imbalance. Gynecomastia can also occur once normal nutrition resumes.
