Kidneys are the natural filters of our body. They perform various functions, including maintaining acid-base balance, regulating blood pressure, producing hormones and reabsorbing water, glucose and amino acids . The symptoms of kidney dysfunction are normally felt via other organs and systems consequently affected. Fatigue, joint and back pain, high blood sugar level and impotence are all symptoms of degenerative kidney health. Recent studies have shown that Cordyceps enhances the kidneys’ potential by increasing 17-hdroxy-corticosteroid and 17-ketosteroid levels (Zhu, J. et al. The Scientific Rediscovery of an Ancient Chinese Herbal Medicine: Cordyceps sinensis The Journal Of Alternative And Complementary Medicine [part 1]Volume 4, Number 3, 1998, pp. 289—303 [part 2] Volume 4, Number 4, 1998, pp. 429 - 457.).
The best initial screening test for Cushing's syndrome is the 24-hour urinary free cortisol measurement. 17 Although some authors 16 do not support screening for Cushing's syndrome in the absence of clinical signs or symptoms, other investigators recommend routine measurement of 24-hour urinary free cortisol levels in all patients with incidental adrenal masses. Additional evaluation with a dexamethasone suppression test is warranted if Cushing's syndrome is suspected, a patient has signs or symptoms of the syndrome or the results of the 24-hour urinary free cortisol measurement are equivocal.
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.
