Gynecomasia Causes

Gynecomastia is a condition whereby a man develops swollen breast gland tissues and tenderness of the breast. Gynecomastia causes consist of conditions that result in hormonal imbalance. This medical condition has been found to result from a decrease in the ratio of the testosterone against estrogen in the male body.

Males typically have a higher concentration of testosterone than estrogen. And the imbalance causes female anatomical signs—such as man boobs—to develop. The hormonal imbalance that causes gynecomastia arises when certain triggers cause either an abnormal decrease in the testosterone level or an irregular increase in the estrogen level.

As we have said, gynecomastia causes boil down to hormonal imbalances, which can be triggered by such factors as natural hormonal fluctuations, taking certain medications, and specific health conditions. But these make up only 75 percent of gynecomastia cases. The rest are brought about by unknown causes. How does the testosterone-estrogen imbalance trigger the known gynecomastia causes? Testosterone and estrogen are the hormones that are responsible for developing and maintaining the physical sexual attributes in men and women.

Testosterone particularly dictates how males sexually develop. Its counterpart in women is the estrogen. Contrary to popular belief, males do produce estrogen, although in very low concentrations. Estrogen in men keeps the bone density, mood swings and the production rate of sperms in check. When a man produces more estrogen what the body typically needs, the result is gynecomastia.

Gynecomastia occurs in all stages of physical development of men. Among infants, there are over 50 percent that are born with bigger breasts, as a result of the estrogen that they absorb from their mother. This condition typically wears out after two to three weeks, after which, babies develop normally. Boys in the puberty stage are also prone to develop enlarged breast tissues and tenderness of the breast. This is often caused by hormonal fluctuations that are typical during the puberty stage.

In most cases, the enlargement of the breasts at puberty normalizes within six months to three years without requiring medication. Among adult men, on the other hand, gynecomastia is common at the ages between 50 and 80, with as much as 25-percent suffering from the condition. This is due to the fact that men at this stage has lower metabolic rate, which causes fat to build up in all places.

Certain medications have also been found as among the proven gynecomastia causes. Such medications include: anti-androgens, which are indicated for the treatment of prostate cancer or enlargement; AIDS medications such as what is known as highly active antiretroviral therapy; anti-anxiety drugs; antibiotics; medications used to treat ulcers; cancer treatments; and medications for heart conditions.

Finally, there are also certain health conditions that have been found to be among the most common gynecomastia causes. Such health conditions include hypogonadism, or conditions that impair the normal rate of testosterone production; aging, which normally causes hormonal fluctuations and obesity; tumors in body parts that affect hormonal balance; hyperthyroidism, which is characterized by overproduction of the thyroid gland; and kidney and liver conditions.
