Chronic inflammation that swings between flares and remission — treated through microbiome restoration, nervous-system regulation, and anti-inflammatory protocols.

Learn more

Bloody diarrhea, urgency, and unpredictable flares driven by reduced bacterial diversity and barrier dysfunction — addressed at the terrain to reach lasting remission.

Learn more

Bloating, brain fog, and symptoms that don't respond to the usual treatments — often Candida overgrowth, resolved with targeted antifungal and microbiome protocols.

Learn more
Increased Intestinal Permeability (Leaky Gut)

Increased Intestinal Permeability (Leaky Gut)

A compromised intestinal barrier behind unexplained food sensitivities and body-wide inflammation — reversed by assessing and restoring the gut lining.

Learn more

Chronic heartburn and regurgitation where acid-blockers only partly help — investigated for the motility and mechanical drivers actually behind the reflux.

Learn more

Infrequent, straining, incomplete bowel movements — investigated for the true mechanisms driving them rather than managed with lifelong laxatives.

Learn more
Gut Microbiome & Dysbiosis

Gut Microbiome & Dysbiosis

An imbalance in the trillions of microbes shaping digestion, immunity, and mood — mapped through advanced testing and restored with personalized terrain work.

Learn more
Gastritis & Ulcers

Gastritis & Ulcers

Stomach-lining inflammation and peptic ulcers — assessed for H. pylori, NSAID burden, and stress drivers, and healed with targeted protocols rather than lifelong acid suppression.

Learn more
Celiac & Food Sensitivities

Celiac & Food Sensitivities

From confirmed celiac to non-celiac sensitivities — diagnosed with comprehensive testing and managed through nutrition, terrain repair, and lifestyle.

Learn more

Abdominal pain and unpredictable bowel habits that are rarely just stress — up to 70% trace to treatable root causes like SIBO or food sensitivities.

Learn more

Weight that won't move despite doing everything right — treated as metabolic, hormonal, and microbiome dysfunction rather than a willpower problem.

Learn more
Histamine Intolerance & MCAS

Histamine Intolerance & MCAS

Flushing, food reactions, and multi-system symptoms from histamine and mast-cell dysregulation — traced back to gut dysbiosis, SIBO, and barrier function.

Learn more
Hemorrhoids

Hemorrhoids

Rectal bleeding and swelling that topical treatments only soothe — resolved by addressing the constipation, motility, and pressure patterns beneath them.

Learn more
Fatty Liver Disease (MASLD/NAFLD)

Fatty Liver Disease (MASLD/NAFLD)

A silent, common liver condition tied to gut dysfunction and metabolic dysregulation — addressed through the gut–liver axis to halt and often reverse it.

Learn more
Hiatal Hernia

Hiatal Hernia

Heartburn, post-meal chest pain, and swallowing trouble that isn't only GERD — addressed structurally and at the pressure and diaphragm factors behind it.

Learn more
Diverticular Disease

Diverticular Disease

Pouches in the colon wall and the flares they can bring — managed with diet, microbiome support, and root-cause care across diverticulosis and diverticulitis.

Learn more

Our approach

Why Whole Gut Health is different.

At Whole Gut Health, we go beyond conventional symptom management and traditional functional medicine protocols. We trust your body's innate ability to heal itself when given the right support.

In Dr. Shustina's many years of practice, she has seen that many digestive diseases have their root cause in emotional traumas and unhealed wounds. When these underlying causes are healed, the body can heal from the inside out in a lasting way.

We focus on the mind-gut connection, incorporating energy healing techniques, personalized nutrition that evolves as you heal, and integrative approaches addressing mind, body, and spirit. If this resonates with you, contact our office to schedule your consultation and take the first step on your healing journey.

Expert-led care

Personalized, expert-led.

Dr. Alexandra Shustina, NYC's and Miami's premier gut health specialist, is a board-certified gastroenterologist and internist. She is a gut health specialist with training in conventional gastroenterology and functional gut health, and an expert in the gut microbiome and its role in health and wellness.

At Whole Gut Health, our care is led by experienced functional medicine clinicians with a deep understanding of the gut microbiome and advanced diagnostics. We combine evidence-based strategies from conventional gastroenterology with a functional and integrative lens to give you the clarity and support needed for long-term healing.
