Fatigue can be due to food sensitivities, hormonal imbalances, and blood sugar problems.
Hormonal: Adrenal hormones and thyroid hormones regulate energy levels.
Digestive: Unstable blood sugar, over-consumption of carbohydrates and sweets, and food sensitivities all contribute to fatigue, and chronic, undetected infections that weaken immune function are a leading cause of fatigue.
Detoxification: The inability to eliminate heavy metals and chemicals stored in the body can contribute to fatigue.
