In today’s healthcare world, patients are searching for answers beyond prescriptions and quick fixes. Many people feel like they are simply “managing” their health instead of truly getting better. If this sounds familiar, you’re not alone. That’s exactly why functional medicine has grown into such an important and patient-centered approach to care.

At Sheen Vein (Aesthetics and Functional Medicine) in the St. Louis area, we use functional medicine to help patients uncover and treat the root causes of their symptoms rather than just covering them up. This article will give you a comprehensive overview of what functional medicine is, how it differs from conventional care, and how it may be the missing piece in your health journey.

What Is Functional Medicine?

Functional medicine is a systems-based, science-driven approach to healthcare. Instead of focusing only on the diagnosis or disease label, functional medicine asks “Why is this happening?” and “How are the body’s systems connected?”

The philosophy is simple: your body is designed to heal and regulate itself. When something goes wrong, whether it’s fatigue, brain fog, chronic pain, or autoimmune disease, the functional medicine clinician’s job is to figure out what’s interfering with that process.

This model combines the best of modern diagnostic science with natural therapies, nutrition, and lifestyle interventions—creating highly personalized treatment plans.

How Functional Medicine Differs from Conventional Medicine

While conventional medicine is essential for acute care (like infections, emergencies, or surgeries), it often falls short in addressing chronic conditions such as diabetes, autoimmune disorders, or persistent fatigue.

Here are some key differences:

• Conventional Medicine: Focuses on symptom suppression, often with medications.
• Functional Medicine: Focuses on finding and correcting the root cause.
• Conventional Medicine: Visits are often short and directed toward immediate concerns.
• Functional Medicine: Visits are longer and explore the whole person—history, lifestyle, stress, sleep, nutrition, and environment.
• Conventional Medicine: Treats each organ or symptom separately.
• Functional Medicine: Looks at how all systems (gut, hormones, immune, brain, etc.) are interconnected.

For example, if you struggle with depression, conventional care may prescribe an antidepressant. A functional medicine clinician will look deeper: Is there inflammation in the gut? Is thyroid function suboptimal? Are nutrient deficiencies contributing? By addressing those imbalances, mood often improves more naturally.

Core Principles of Functional Medicine

Several principles guide functional medicine care:

1. Personalized Care

Every patient is unique. Two people with the same diagnosis may have completely different root causes. Functional medicine tailors treatment to the individual, not the label.

2. Root-Cause Thinking

Rather than asking “What pill for what ill?” functional medicine asks:

• What imbalances are driving this?
• How did genetics, lifestyle, and environment contribute?
• What is the sequence of events leading to disease?

3. Systems Biology Approach

Your gut health, hormone balance, immune system, brain chemistry, and even mitochondrial energy production are all interconnected. Functional medicine maps these connections.

4. Empowering the Patient

Patients are not passive recipients of treatment. They are active participants. Education, lifestyle change, and self-care are central.

Tools and Treatments Used in Functional Medicine

Functional medicine isn’t about rejecting conventional care—it’s about expanding it. We use advanced tools to investigate and treat the root cause of disease.

Advanced Diagnostic Testing

We often look beyond standard lab panels. Functional testing may include:

• Comprehensive stool analysis to evaluate the gut microbiome
• Food sensitivity and nutrient absorption testing
• Hormone panels (thyroid, adrenal, sex hormones)
• Inflammation and immune function markers
• Mitochondrial and metabolic assessments

Nutrition and Lifestyle Medicine

Food is medicine. Correcting nutrient deficiencies, removing inflammatory foods, and restoring balance through diet are central to functional medicine. Sleep, stress, and movement are equally important.

Supplements and Natural Therapies

Evidence-based supplementation (like vitamin D, magnesium, omega-3s, or targeted botanicals) is often used to restore balance.

Hormone Optimization

For men and women struggling with symptoms of imbalance, carefully monitored hormone replacement therapy (HRT) may be part of the plan.

Regenerative and Innovative Therapies

At Sheen Vein, we also integrate therapies like red light therapy with PEMF, peptide therapy, and regenerative treatments such as PRP/PRF. These therapies help restore function at a cellular level, complementing the functional medicine approach.

Conditions Functional Medicine Can Address

Because functional medicine focuses on root causes, it can help with a wide range of chronic symptoms and conditions, including:

• Fatigue and brain fog
• Digestive issues (IBS, bloating, reflux, leaky gut)
• Autoimmune conditions (lupus, rheumatoid arthritis, Hashimoto’s)
• Hormonal imbalances (thyroid, PCOS, menopause, low testosterone)
• Skin conditions (eczema, psoriasis, acne, rosacea)
• Metabolic concerns (diabetes, insulin resistance, high cholesterol)
• Anxiety and depression linked to physiological imbalances

Many of our patients at Sheen Vein have been to multiple doctors and specialists without answers. Functional medicine often brings clarity by connecting the dots.
