This document discusses how hormones change with aging and menopause. It notes that hormones are produced by various organs and tissues in the body, including the hypothalamus, pituitary gland, thyroid, parathyroid glands, pancreas, adrenal glands, kidneys, ovaries, and testes. These hormones decline with aging, which can affect functions like metabolism, bone health, blood glucose, and sex hormone levels. Symptoms of menopause like hot flashes and sleep issues are also discussed, as well as factors that affect the onset of menopause and treatment options. Depression is another common issue related to changing hormone levels during menopause.
