July Webinar Recap: Understanding the Connection Between GLP-1s and Your Hormones 

If you’ve started a GLP-1 medication and noticed changes beyond the number on the scale, you’re not imagining it. 

Maybe your appetite has changed (of course), but so has your energy. Your menstrual cycle feels different. Your mood is shifting. You’re wondering whether your hair shedding is normal, or whether perimenopause is starting. It can be difficult to know what’s connected to your medication, what’s connected to weight loss itself, and what may have been happening beneath the surface all along. 

That’s exactly what we explored during our July webinar, where Functional Health Manager Jennah Nelson and Nurse Practitioner Jillian Deaton unpacked the relationship between GLP-1 medications and hormones, and why understanding the bigger picture is one of the most important parts of a successful health journey. 

Here are the biggest takeaways from the session. 

GLP-1 Is Already One of Your Hormones 

One of the biggest misconceptions surrounding GLP-1 medications is that they’re introducing something completely foreign into the body. The truth is, your body produces its own GLP-1 hormone every time you eat. 

Your body’s natural GLP-1 only sticks around for a few minutes. GLP-1 medications work in a similar way, but they’re designed to last much longer, providing a more sustained effect. 

When you eat, your intestines release GLP-1 to help coordinate what happens next. It signals to your brain that food has arrived, reduces food noise, helps your pancreas release insulin when it’s needed, and slows digestion so your body has time to absorb nutrients and recognize fullness. 

Because GLP-1 is part of an interconnected hormonal network, it influences much more than appetite alone. Blood sugar regulation, metabolism, digestion, inflammation, stress hormones, and energy are all connected. Rather than working independently, these systems constantly communicate with one another. 

That’s why improvements in one area often create positive changes somewhere else. 

Weight Loss Changes Your Hormonal Environment 

Another key takeaway from the conversation was that weight loss itself changes hormones. 

Fat tissue isn’t simply stored energy. It’s hormonally active tissue that produces and influences several important hormones throughout the body. 

As body fat decreases, many hormones begin shifting, including: 

• Insulin sensitivity often improves, allowing the body to use glucose more efficiently. 

• Leptin (“the I’m full hormone”) becomes easier for the brain to recognize, improving satiety signals. 

• Ghrelin (“the hunger hormone”) naturally increases during weight loss as the body tries to protect its energy stores. 

• Estrogen production can change because fat tissue contributes to estrogen production. 

• Inflammatory signals often decrease as body fat declines. 

These changes help explain why so many people notice improvements beyond the scale. Think: less joint pain, better mobility, more energy, reduced inflammation, and improved metabolic health. Many participants shared that they didn’t realize how poorly they had been feeling until those symptoms started improving. 

Not Every Symptom Is Caused by Your GLP-1 

Questions about hair loss, irregular periods, fatigue, mood changes, hot flashes, and low libido came up repeatedly during the webinar. 

The answer wasn’t as simple as blaming the medication. Instead, Jennah and Jillian encouraged patients to zoom out and ask a bigger question: 

What else is happening in the body? 

Sometimes symptoms are related to: 

• The normal hormonal adjustments that happen during weight loss 

• Nutrient deficiencies 

• Existing hormone imbalances that are only now becoming noticeable 

• Perimenopause or menopause 

• Thyroid dysfunction 

• Iron deficiency 

• PCOS 

• Lifestyle factors like poor sleep, chronic stress, or under-fueling 

As Jillian explained, beginning a GLP-1 journey can sometimes feel like cleaning out a closet. The medication didn’t necessarily create the problem. It simply made an existing issue easier to recognize. 

That’s why individualized care is so important. A provider can help determine whether your symptoms are medication-related or if other factors may be contributing. 

The Foundation Still Matters 

One message came through again and again throughout the session: 

A GLP-1 is a tool. It’s not a replacement for healthy habits. The medication may quiet food noise, but your body still needs fuel. 

Jennah highlighted one of the most common patterns the team sees: 

Patients report they aren’t eating until two or three in the afternoon because they simply aren’t hungry. While eating less may feel like success, it can often create new problems. 

Chronically undereating can contribute to: 

• Hair loss 

• Muscle loss 

• Increased cortisol 

• Poor recovery 

• Lower energy 

• Difficulty maintaining long-term weight loss 

For lasting success, Jennah and Jillian emphasized building a strong foundation through: 

• Adequate protein intake 

• Resistance training to preserve muscle 

• Consistent sleep 

• Stress management 

• Nutrient-dense meals 

• Personalized guidance from healthcare providers 

The goal isn’t to eat as little as possible. The goal is to nourish your body well enough that it can lose weight while still functioning optimally. 

How Do You Know If It’s the Medication or Your Hormones? 

This is one of the questions providers hear most often. Jillian recommended paying close attention to timing. 

Medication-related side effects often appear shortly after: 

• Starting treatment 

• Increasing a dose 

• Making another medication adjustment 

Hormone-related symptoms, on the other hand, often develop gradually over months or even years and may have existed before beginning a GLP-1. 

Questions worth asking include: 

• Have I experienced this before? 

• Did this symptom begin immediately after changing my medication? 

• Does it follow a predictable pattern? 

• Has it continued even after adjusting my dose? 

Those clues can help providers determine whether symptoms are medication-related, hormone-related, or caused by something else entirely. 

Hormone Optimization Means Looking at the Whole Person 

At Ivim, hormone optimization isn’t about chasing perfect lab numbers. It’s about understanding why you’re experiencing symptoms and creating an individualized plan that supports your entire health picture. 

That means evaluating things like: 

• Nutrition 

• Sleep 

• Stress 

• Exercise 

• Medical history 

• Hormone levels 

• Lifestyle habits 

• Personal goals 

From there, our providers can determine whether lifestyle changes alone are appropriate or whether supplements, hormone therapy, medications, or a combination of approaches would provide the greatest benefit. 

As Jillian explained, one size never fits all. 

The Bottom Line 

Your GLP-1 journey is about much more than losing weight. As your body changes, your hormones, metabolism, inflammation, and nutrient needs change too. Some symptoms may be part of normal adaptation. Others may point toward nutritional gaps or underlying hormone concerns that deserve attention. 

The most successful journeys happen when medication is paired with strong lifestyle foundations and personalized medical care. 

If something feels different, don’t assume it’s “just the medication.” Ask questions. Work with your care team. Pay attention to your body. Because understanding what’s happening beneath the surface is just as important as watching the number on the scale.
