Adrenal failure (stress) is characterized by fatigue and inability to cope with diseases or everyday stresses. Adrenal failure directly affects your ability to resist disease or heal a current disease. An adrenal function test can be performed in the following manner. Take base blood pressure in a lying down position, after five minutes then stand up suddenly-pulse pressure should increase by a minimum of ten points; if not, your adrenals need help. Concurrent signs and symptoms may include colitis, ulcers and low WBC count.
