How Do Hormones Work?

Hormones are chemical messengers produced by various glands and tissues in the body. They play a crucial role in regulating physiological processes and maintaining homeostasis (internal stability) within the body. They help control metabolism, growth and development, mood, reproduction, and many other functions. Imbalances in hormone levels can lead to a variety of health issues, including hormonal disorders, infertility, and mood disorders. Therefore, maintaining proper hormone balance is essential for overall health and well-being. As we age, our hormone levels have a tendency to change and fluctuate. 

Dr. Orbeck discusses how hormones work on our YouTube channel, here. When hormones are created in the body with optimal functionality in sex organs, hormones are released according to the brain’s needs within the body. The pituitary gland is the head of the endocrine system, which monitors and sends out signals to produce specific hormones.  

Read on to learn more about the process of hormonal function in the body.

Production and Release

Hormones are developed in specialized cells or glands in response to signals from the nervous system, other hormones, or changes in bodily conditions.


Once produced, hormones are released into the bloodstream. They travel throughout the body and can reach distant target cells and tissues.

Recognition by Target Cells

Hormones circulate in the bloodstream until they reach specific target cells or tissues. These cells have receptors that are specific to particular hormones. The hormone binds to its receptor on the surface or inside the target cell.

Signal Transduction

When a hormone binds to its receptor, it initiates a series of biochemical reactions within the target cell. This process is known as signal transduction. The specific pathways activated depend on the hormone and the type of receptor.

Cellular Response

The biochemical reactions triggered by hormone-receptor binding lead to specific cellular responses. These responses can include changes in gene expression, alterations in enzyme activity, modifications in cell membrane permeability, or other effects that regulate the function and behavior of the target cell.

Feedback Mechanisms

Hormone levels in the bloodstream are tightly regulated through feedback mechanisms. These mechanisms involve signals that control hormone production and release, ensuring that hormonal balance is maintained.

Effects on Body Functions

Different hormones have specific roles and functions in the body, often working together in complex networks to maintain overall health.

Bioidentical Hormone Replacement Therapy at Regenerative Medical Institute

At RMI, we specialize in bioidentical hormone replacement therapy (BHRT), a process through which hormones are administered into the body to provide better functionality and relief from symptoms of hormonal imbalances. We customize our treatment plans to optimize results for our patients. Visit our website or call our office to schedule a free consultation, and find out if BHRT is right for you: 877-573-3737.
