Due to our modern society with the many physical and emotional stresses, probably half the population possess varying degrees of adrenal malfunction. As we are under stress for long periods of time our adrenals produce two hormones called cortisol and norepinephrine. Over time, our adrenals by producing more hormones than they were made to comfortably manufacture and secrete, will "burn out" and decrease their secretion. At that time the body loses its capacity to cope with stress, you become sicker easier and for longer periods of time, and perhaps even a nervous breakdown could result. General symptoms of adrenal malfunction can include (you will probably exhibit a few but not all of the symptoms), low back, and knee pain, tired feet with weak ankles and aching calves. Your eyes will be very sensitive to light especially when driving at night, and you might feel a need to wear sunglasses during most summer days. Depression, hay fever, asthma, bronchitis, colitis, insomnia, learning disabilities, ulcers (due to increased hydrochloric acid production), all may be partially due to adrenal malfunction.
