The other offender in causing left side pain in the lower area of the back is the gallbladder. The gallbladder stores bile that is produced by the liver and this helps the body with food digestion. Problems with your gallbladder are fairly common in industrialized societies. The refined and processed food eaten in these cultures takes a heavy toll on the gallbladder. Recent studies show that over a million Americans have gallstones can have gall stones or a diseased gallbladder and the result is almost always the same. Remove the gallbladder and you remove the pain.
Individuals who have cirrhosis or chronic liver disease may develop gynecomastia for several reasons. Cirrhotics tend to have increased secretion of the androgenic hormone androstenedione from the adrenal glands, increased conversion of this hormone into various types of estrogen,  and increased levels of SHBG, which leads to decreased blood levels of free testosterone.  Approximately 10–40% of individuals with Graves' disease (a common form of hyperthyroidism ) experience gynecomastia.  Increased conversion of testosterone to estrogen by increased aromatase activity,  increased levels of SHBG and increased production of testosterone and estradiol by the testes due to elevated levels of LH cause the gynecomastia. Proper treatment of the hyperthyroidism can lead to the resolution of the gynecomastia.
