How Do Hormones Really Work? An Endocrinologist Breaks It Down

Introduction

Hormones are often mentioned in health discussions, yet many people still wonder what they actually do. We constantly hear about "hormone balance" and the health issues that arise when hormones are out of whack, but what exactly are these chemical messengers, and how do they influence our bodies?

Hormones are vital to the functioning of our bodies, acting as messengers that travel through the bloodstream to regulate various physiological processes. From metabolism and growth to mood and stress response, hormones are integral to almost every function in the body. Dr. Rekha Kumar, an endocrinologist and chief medical officer at Found, offers insight into how these powerful substances work and what happens when they go off balance.

What Are Hormones, and Why Do They Matter?

Hormones are produced by the endocrine glands, a group of organs and tissues that include the adrenal glands, thyroid, pancreas, and reproductive organs. "Hormones are produced in the endocrine glands and travel through the bloodstream to perform their roles in different parts of the body," explains Dr. Kumar. These roles can range from regulating your energy levels to controlling your mood and even influencing your reproductive system.

Some of the most well-known hormones include cortisol (often referred to as the "stress hormone"), estrogen and progesterone (key players in sexual development and reproduction), growth hormone, insulin (which helps regulate blood sugar), and testosterone. Each hormone has a specific function, and maintaining the right balance is crucial for good health.

How Does the Endocrine System Work?

The endocrine system is a network of glands and organs that produce, store, and release hormones. According to the Cleveland Clinic, this system includes the adrenal glands, pancreas, thyroid, ovaries, testicles, and more. These glands constantly monitor the levels of hormones in your blood and release more or less as needed to maintain balance.

For instance, if your blood sugar levels rise, your pancreas releases insulin to help your cells absorb the sugar and use it for energy. If you're stressed, your adrenal glands pump out cortisol to help your body cope with the situation.

What Happens When Hormones Go Out of Balance?

Hormonal imbalances can occur when your body produces too much or too little of a particular hormone. This can lead to a range of health issues. "A hormone could either not be doing its job properly or it could be doing too much, causing an underreaction or overreaction that can lead to symptoms," says Dr. Kumar.

Some common hormone-related conditions include thyroid problems (such as hyperthyroidism or hypothyroidism), diabetes, Cushing's syndrome (caused by excess cortisol), and polycystic ovary syndrome (PCOS). These conditions can manifest as unexpected weight changes, fatigue, mood swings, and other symptoms.

Treating Hormonal Issues

If you suspect you have a hormone imbalance, it's important to consult with an endocrinologist. Treatment will depend on the specific condition and may involve hormone replacement therapy, medication, lifestyle changes, or, in some cases, surgery. Dr. Kumar emphasizes the importance of maintaining a healthy lifestyle to support your hormone health. This includes eating a balanced diet, exercising regularly, managing stress, and getting enough sleep.

When to See a Doctor

If you notice subtle but persistent changes in your weight, energy levels, mood, or other aspects of your health, it might be worth discussing these symptoms with your doctor. Hormonal imbalances often develop gradually, so keeping track of changes can help your healthcare provider identify potential issues early on.

In more urgent cases—such as sudden heart palpitations, difficulty breathing, or significant changes in your period or weight—seeking medical attention promptly is crucial.

Hormones may seem like a mysterious part of the body’s inner workings, but understanding them is key to maintaining your overall health. By recognizing the signs of imbalance and taking proactive steps to support your endocrine system, you can help ensure that your hormones continue to work harmoniously for your well-being.
