Taking a More Rooted Approach to Medicine.

Functional medicine offers a more complete way to understand your health: one that looks beyond symptoms to explore how your body’s systems are interconnected.

Here, care begins with listening. I take the time to understand your full health story and identify the patterns that may be contributing to how you feel. Rather than focusing on symptoms alone, I take a deeper, more thoughtful approach, asking:

“Why is this happening in the first place?”

When we can identify the root cause, I can help you create a clearer, more personalized path toward healing and lasting wellness.

MEET YOUR FUNCTIONAL MEDICINE PRACTITIONER

Hi, I’m Isabel Walls.

I am a Board Certified Physician Assistant and Certified Functional Medicine provider with more than 15 years of experience practicing holistic primary care in the Boston area. I’ve cared for patients of all ages across family and primary care, and over time, my work naturally evolved into a more integrative approach: one focused on identifying and addressing the root causes of illness rather than simply managing symptoms.

I serve as a functional medicine expert within a Best of Boston-recognized concierge medical practice, where I work with patients facing complex chronic conditions, including IBS, autoimmune disorders, hormonal imbalances, allergies, and metabolic dysfunction. Now, through Isabel Walls Functional Medicine, I’m able to offer that same thoughtful, personalized care in a more accessible, flexible setting without the need for memberships or traditional time constraints.

This work is more than medicine for me. It’s a calling. It is an honor to walk alongside my patients as they restore their health and rediscover what it feels like to feel truly well.

Gut Restoration & Digestive Healing

Your gut is the foundation of your health.

Here, we focus on repairing digestive function, restoring microbial balance, and calming inflammation that can contribute to symptoms like IBS, reflux, food sensitivities, and chronic bloating.

Through detailed history, advanced testing, and personalized nutrition and lifestyle strategies, we rebuild a healthy gut environment so the body’s interconnected systems can begin to heal.

Hormone Balance & Optimization

Hormones influence nearly every system in the body.

I provide personalized care for patients experiencing symptoms ranging from fatigue and weight gain to mood changes, poor sleep, low energy, and beyond.

Care includes full hormone ecosystem evaluation and, when appropriate, carefully guided bio-identical hormone therapy alongside lifestyle and metabolic support.

Metabolic Health & Weight Wellness

Weight changes are often a symptom of deeper metabolic disruption.

This program addresses root drivers, including inflammation, insulin resistance, gut health, sleep, hormones, and chronic stress, to restore metabolic flexibility.

The goal is sustainable energy, a higher-functioning metabolism, and long-term cardiometabolic resilience, with the option for GLP-1 support if indicated.

Integrative Skin & Immune Health

Skin conditions often reflect deeper internal imbalances.

Drawing on experience in integrative medicine and dermatology, I work with patients experiencing concerns such as acne, eczema, psoriasis, and other inflammatory skin conditions.

Care focuses on identifying root contributors, including gut health, immune activation, hormone imbalance, and nutrient deficiencies, to support true healing from within.
