Dr. Shustina is an incredibly knowledgeable doctor who truly takes time to find root cause.
Whole-Person Care for Complex Gut Conditions
Complex digestive, immune, metabolic, and systemic conditions addressed through thoughtful diagnostics and personalized, integrative care—offering a deeper understanding of illness and a path toward lasting healing when conventional approaches have failed to provide answers or meaningful relief.
Complex conditions, treated as a whole.
Personalized assessment and targeted testing, combined with nervous system regulation, nutrition and osteopathy to better understand complex symptoms and support meaningful, lasting healing.

Inflammatory Bowel Disease (IBD)
Chronic immune-mediated inflammation of the GI tract, driven in large part by microbiome dysbiosis — addressed beyond symptom suppression to support lasting remission.
Learn more
Crohn's Disease
Chronic inflammation that swings between flares and remission — treated through microbiome restoration, nervous-system regulation, and anti-inflammatory protocols.
Learn more
Ulcerative Colitis
Bloody diarrhea, urgency, and unpredictable flares driven by reduced bacterial diversity and barrier dysfunction — addressed at the terrain to reach lasting remission.
Learn more
Small Intestinal Bacterial Overgrowth (SIBO)
Bloating, gas, and end-of-day distention from bacterial overgrowth in the small intestine — pinpointed with breath testing and a precise, subtype-aware plan.
Learn more
Small Intestinal Fungal Overgrowth (SIFO)
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)
A compromised intestinal barrier behind unexplained food sensitivities and body-wide inflammation — reversed by assessing and restoring the gut lining.
Learn more
GERD / Acid Reflux
Chronic heartburn and regurgitation where acid-blockers only partly help — investigated for the motility and mechanical drivers actually behind the reflux.
Learn more
Chronic Constipation
Infrequent, straining, incomplete bowel movements — investigated for the true mechanisms driving them rather than managed with lifelong laxatives.
Learn more
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
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
From confirmed celiac to non-celiac sensitivities — diagnosed with comprehensive testing and managed through nutrition, terrain repair, and lifestyle.
Learn more
Irritable Bowel Syndrome (IBS)
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
Sustainable Weight Loss
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
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
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)
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
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
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
Colon Cancer Prevention
Evidence-based screening paired with diet, microbiome, and lifestyle optimization — because truly preventing polyps goes beyond scheduling a colonoscopy.
Learn moreThe symptoms that shouldn't be normalized.
Bloating
Persistent bloating and distension — traced to SIBO, dysbiosis, motility, and food reactivity rather than managed with avoidance alone.
Heartburn
Chronic heartburn addressed at the level of motility, hiatal mechanics, and the microbiome — not just long-term acid suppression.
Abdominal Pain
Recurrent abdominal pain investigated for its true drivers — inflammation, visceral tension, and gut-brain dysregulation.
Constipation
Sluggish, incomplete bowel movements resolved through motility support, terrain repair, and nervous-system regulation.
Diarrhea
Chronic or recurrent diarrhea traced to its real drivers — food sensitivities, infections, and imbalances in gut flora — not just slowed.
Rectal Bleeding
GI bleeding taken seriously as a signal — evaluated thoroughly and addressed at its source, never dismissed.
Incomplete Evacuation
That unfinished feeling after a bowel movement — traced to pelvic-floor, motility, and structural contributors.
Anxiety
Anxiety with a digestive thread — approached through the bidirectional gut-brain axis and the microbiome's role in mood.
Depression
Low mood and the gut-brain connection — supporting neurotransmitter production, inflammation, and the terrain beneath it.
Fatigue
Persistent fatigue investigated through gut absorption, the microbiome, inflammation, and metabolic function.
Weight Gain
Unexplained weight gain treated as a microbiome, hormone, and inflammation problem — not a willpower problem.
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.
