Hormonal: Most depression is related to adrenal or sex hormone imbalances. Lower than normal levels of DHEA, cortisol, testosterone, estrogen or progesterone will trigger a biomechanically induced depression. Neuroscientists at the National Institute of Mental Health, our nation’s leading mental health facility, have stated that most depression in the United States is caused by adrenal hormone imbalances. Hormonal imbalances cause immune suppression, which leads to chronic infections. People with undiagnosed chronic infections consistently become depressed simply because they are sick. Most chronic infections do not cause obvious symptoms so they are left untreated.
Digestive: One of the well-established side effects of food intolerances and food allergies is depression. Furthermore, insufficient protein digestion deprives the body amino acids from which you make many of the key brain chemicals.
Detoxification: The inability to eliminate harmful chemicals or heavy metals from body tissues allows these toxins to build up to harmful levels. Many of these substances such as mercury and petroleum based chemicals easily penetrate our central nervous system, our brain and spinal cord, and cause depression. One of the most frequently reported benefits of a safe and effective detoxification program is alleviation of depression.
