Functional Medicine at Glow Health & Wellness

Functional medicine is a personalized, science-based approach to healthcare that focuses on understanding the root causes of symptoms rather than simply treating them at the surface. At Glow Health & Wellness, we use functional medicine to help you uncover why you feel the way you do—and to guide your body back toward balance, energy, and long-term wellness. Whether you visit our Destin clinic in person or take advantage of our Telehealth services throughout Florida and Alabama, our goal is to offer a comprehensive, thoughtful, and individualized approach to your health.

Leading our functional medicine program is Casey Posey, MSN, APRN-BC, a compassionate and highly skilled Nurse Practitioner known for her deep commitment to patient-centered care. Casey’s blend of experience in traditional medicine, advanced training in functional and integrative approaches, and her genuine passion for wellness allows her to provide a level of care that is both comprehensive and deeply personalized.

Meet Casey Posey, MSN, APRN-BC

As Glow Health & Wellness’ Functional Medicine and Hormone Specialist, Casey Posey brings years of clinical experience and a strong understanding of how the body’s systems connect and influence one another. Her background in both primary care and integrative health gives her a unique perspective: she understands the medical side, but she also looks beyond basic labs and symptoms to see the whole person—your lifestyle, stress, sleep patterns, nutrition, hormones, gut health, and overall well-being.

Casey believes patients deserve the time and attention needed to truly understand their bodies. She is known for listening carefully, asking the right questions, explaining complex concepts in a clear and supportive way, and creating treatment plans that are both realistic and effective. Her warmth, clinical expertise, and dedication to her patients are at the heart of what makes Glow Health & Wellness’ functional medicine program different.

What Functional Medicine Means at Glow Health & Wellness

Functional medicine takes a deeper approach than traditional models. Instead of focusing only on symptoms, we ask important questions: What is causing these symptoms? How are different systems interacting? What imbalances or disruptions need to be corrected?

Casey evaluates your health through a holistic lens—considering hormones, inflammation, immune function, metabolism, gut health, stress response, and more. This integrative model allows her to identify patterns that traditional care may overlook.

Many of our patients come to us feeling unheard or frustrated after being told that their labs are “normal” despite feeling far from well. Casey understands that optimal health looks different from simply falling within a laboratory reference range. She focuses on reaching your optimal levels—restoring balance so you can feel energized, clear-headed, and healthy again.

Symptoms Are Clues—Not the Problem

Your body communicates through symptoms. Things like fatigue, irritability, insomnia, bloating, slowed metabolism, weight changes, brain fog, mood swings, hair thinning, digestive issues, or low libido are not random—they are indicators that something deeper needs attention.

Functional medicine views these symptoms as valuable clues.

For example:

Fatigue may be connected to cortisol imbalance, nutrient depletion, low thyroid activity, mitochondrial health, chronic inflammation, or hormone imbalance. Weight gain may be tied to insulin resistance, cortisol dysregulation, inflammation, gut health, or perimenopausal hormone shifts. Mood changes may reflect estrogen changes, progesterone decline, thyroid dysfunction, inflammation, gut-brain disruption, or sleep dysregulation.

Casey investigates why these symptoms are happening so treatment can address the root cause—not just temporarily mask the discomfort.

A Thorough, Personalized Evaluation

Your functional medicine journey begins with an in-depth consultation—either in the clinic or through Telehealth—where Casey listens to your history, concerns, lifestyle patterns, medications, symptoms, and goals. She takes time to understand the full picture of your health, recognizing that true wellness cannot be rushed.

When necessary, Casey orders advanced laboratory testing that looks beyond basic screening. This may include inflammation markers, hormone panels, thyroid studies, gut health indicators, nutrient evaluations, insulin sensitivity, cortisol rhythm, and more. This deeper insight allows her to design a personalized treatment plan that aligns with your body’s needs.

Functional Medicine and Hormone Optimization

Hormones influence nearly everything you experience—energy, metabolism, sleep, mental clarity, mood stability, libido, weight, skin health, and even immune function. When hormones fall out of balance, the effects ripple through your entire system.

Casey specializes in identifying hormonal imbalances in both women and men, including estrogen, progesterone, testosterone, thyroid hormones, insulin, and cortisol. Many patients begin experiencing symptoms long before they reach menopause or andropause. Casey is skilled at identifying early shifts and correcting them proactively through bioidentical hormone therapy, lifestyle adjustments, peptides, and supportive supplements.

Her approach empowers you to understand what your body is doing and how to restore harmony.

Thyroid Health Through a Functional Lens

The thyroid is one of the most misunderstood and underdiagnosed contributors to fatigue, weight gain, depression, hair thinning, constipation, and metabolic slowdown. Many people are told their thyroid function is “normal,” even when key symptoms persist.

Casey evaluates thyroid health comprehensively by analyzing TSH, Free T3, Free T4, Reverse T3, thyroid antibodies, and patterns of conversion. She focuses on optimizing—not just normalizing—your thyroid function so you can feel like yourself again.

Gut Health, Inflammation, and Whole-Body Wellness

Your gut plays a central role in immune health, hormone metabolism, emotional regulation, inflammation, and weight. Gut disruptions are common due to stress, diet, medications, infections, inflammation, and food sensitivities.

Casey’s functional medicine approach identifies what is affecting your gut microbiome and digestive system. By restoring balance, patients often experience dramatic improvements in symptoms such as bloating, constipation, diarrhea, acne, eczema, fatigue, and mood fluctuations.

Healing the gut often leads to improvements throughout the entire body.

Understanding Stress and Cortisol

Chronic stress is one of the driving forces behind hormone disruption, weight gain, anxiety, sleep problems, and inflammation. Casey evaluates how your nervous system and adrenal glands are responding to daily stressors. By understanding your cortisol rhythm, she can design a plan to restore balance through lifestyle adjustments, supplements, peptides, and hormone support when indicated.

When cortisol is balanced, everything improves—energy, mood, metabolism, sleep, and resilience.

Nutrition and Lifestyle Support

Instead of rigid dieting, functional medicine nutrition focuses on nourishing your body in a way that reduces inflammation, balances blood sugar, supports gut health, and enhances hormonal harmony. Casey’s guidance is realistic and designed to fit into your daily life. She emphasizes protein balance, nutrient density, anti-inflammatory foods, and patterns that stabilize your metabolism and energy.

Her approach helps you build sustainable habits—not quick fixes that fade over time.

Personalized Treatment Plans Designed for You

Your functional medicine plan with Casey may include hormone therapy, medical weight loss medications or peptides, gut support, IV nutrient therapy, lifestyle optimization strategies, vitamin supplementation, stress modulation, sleep support, and advanced therapeutic tools that bring your body back into balance.

Each plan is unique. Casey tailors every recommendation to your labs, symptoms, lifestyle, and goals so that healing is both achievable and sustainable.

Functional Medicine Through Telehealth

Glow Health & Wellness provides full Telehealth access to patients throughout Florida and Alabama. Your consultation, lab discussions, treatment planning, and follow-up visits can all be completed virtually, giving you high-level care from the comfort of your home. Medications and supplements can be shipped directly to you, and lab work can be completed at local testing centers.

Casey’s Telehealth patients receive the same individualized, attentive care as those seen in person.

Functional Medicine In the Clinic

For those who prefer in-person care, our Destin clinic offers a warm and inviting environment where Casey provides face-to-face evaluations, physical assessments, and access to in-clinic services such as IV therapy, injections, aesthetics, and additional testing. Many patients choose to start their journey in person and continue with Telehealth for convenience.

What Patients Experience Over Time

As your personalized plan begins correcting underlying causes, many patients experience significant improvements: deeper sleep, improved mood, more stable energy, clearer thinking, easier weight loss, stronger digestion, balanced hormones, and reduced inflammation. Over time, your body begins functioning the way it was designed to function, allowing you to feel better naturally and consistently.
