Hormonal imbalance happens when there is too little or too much of a hormone in the bloodstream. The role of hormones as messengers or regulators in the body is essential for the proper functions of many of the body’s organs and tissues. Hormones are produced by the glands of the endocrine system.   Hormones are essential in regulating most major bodily functions. Hormones regulate metabolism, growth, blood pressure, reproductive functions, and mood and stress levels. Imbalances in steroids, insulin, growth hormones, and adrenaline affect women and men alike. The main hormonal changes women experience are with progesterone, estrogen and testosterone. Men also experience changes and imbalance in both estrogen and testosterone levels.
