Hormones are chemical messengers that are produced by endocrine glands. They control hunger, emotions, and the reproduction system. Relationship stress, work stress, physical stress, and dietary stress can lead to hormonal imbalance through increased cortisol levels. Poor digestive function can have an impact on adrenal hormones, thyroid hormones, and sex hormones. It is imperative to your entire system to balance good and bad bacteria in your gut.
