Endocrine System: Hormone Insufficiency And Excess

The endocrine system works best when a moderate amount of each hormone is secreted in order to maintain homeostasis, or balance in the body. But if too little of a particular hormone is secreted, that causes a hormone insufficiency in the body. Conversely, if too much of a particular hormone is secreted, that causes a hormone excess in the body. Both hormone insufficiency and excess can cause disease.
