The analogy has been used that while the thyroid gland is the accelerator, the adrenal glands must provide the gas. Unfortunately, today, many individuals suffer from Adrenal Fatigue, and can not respond appropriately when they receive the signal. Dr. James L. Wilson, author of Adrenal Fatigue: The 21st Century Stress Syndrome, notes it is impossible for a person with tired adrenal glands to achieve optimal hormonal balance. Anti-inflammatory and anti-oxidant adrenal hormones like cortisol help to minimize allergic and negative reactions, such as cancer and autoimmune disorders. These hormones closely affect the utilization of carbohydrates and fats, the conversion of fats and proteins into energy, and cardiovascular and gastrointestinal function. Recommendations to improve adrenal health include eating wholesome food, getting plenty of sleep, regular moderate exercise, stress management, slowing down to regain a proper perspective on life, taking appropriate supplements for adrenal support, and replacement of deficient hormones.
The adrenal glands secrete hormones such as cortisol, estrogen, and testosterone that are essential to health and vitality and significantly affect total body function. After mid-life, the adrenal glands gradually become the major endogenous source of sex hormones in both men and women. Intense or prolonged physical or emotional stress commonly associated with modern lifestyles or chronic illness can lead to Adrenal Fatigue, which is an important contributing factor in health conditions ranging from allergies to obesity.
