Hormones are chemicals produced by different glands and tissues, forming a part of the endocrine system. Hormones travel to organs and signal what function they need to perform and when. Hormones help regulate various processes in the body, including the immune and reproductive systems. An hormonal imbalance means a person has too little or too much of a certain hormone, such as insulin, cortisol, androgens, estrogen, or progesterone.
