The cause of adrenal fatigue is simple. And it is usually not what the experts are telling you. Stop buying expensive herbs and other crap to fix this problem. That is not a real, permanent solution to anything. The cause of adrenal fatigue is excessive stressors:
-insufficient calories, less than hunger dictates
-insufficient carbs, less than what cravings dictate
-too much fluids, beyond what thirst dictates
-insufficient salt, below what cravings dictate
-insufficient sleep and excessive exercise
-excessive mental stress
Get the idea? Your body is trying to save you, and you are ignoring it. Theres a bit more to it than that, but that is the primary reason people are suffering.
