The hormone is a chemical produced by glands in the endocrine system. It travels through the bloodstream to the tissues and the organs while delivering a message that tells the organs what to do and when to do it. Hormones help our organs to regulate physiology and behavior. Hormones have various chemical structures in which eicosanoids, steroids, amino acid/protein derivatives are mainly of three classes.
The glands which secrete hormones comprise the endocrine signaling system. While communicating with tissues and organs, hormones serve for physiological regulation and behavioral activities such as metabolism, digestion, tissue function, respiration, sensory perception, sleep, excretion, lactation, stress induction, growth and development, movement, reproduction, and mood manipulation.
Hormonal imbalance occurs when there is too little or too much hormone present in the bloodstream. Due to its essential role in the body, even a small hormonal imbalance can cause side effects in our body.
Men and women both can be affected by imbalances in steroids, insulin, growth of hormones, and adrenaline. Men are more tend to experience imbalances in testosterone levels while women can experience imbalances in estrogen and progesterone levels.
