For too many people, fatigue and weakness are constant parts of daily life. Middle-aged workers grow steadily, inexplicably worn out. Young, active, hyperresponsible (and overly stressed) individuals suddenly burn out. And, many times, they don’t find the cure they need by visiting their doctor. Often, the symptoms aren’t caused by the things most doctors instinctively look for, such as a malfunctioning thyroid, so the individual is left tired, weak,and lacking effective treatment. In many cases, the mysterious cause of their fatigue lies in the adrenal gland.
