Crohn’s Disease

Unpredictable abdominal pain, chronic fatigue, and digestive symptoms that fluctuate between flares and remission aren’t simply "sensitive digestion"—they may signal Crohn’s disease, a chronic inflammatory condition affecting over 750,000 Americans and approximately 6 to 8 million people worldwide. Research has established that gut microbiome dysbiosis plays a fundamental role in Crohn’s pathogenesis, with characteristic reductions in beneficial bacteria and overgrowth of inflammatory species triggering immune dysfunction and intestinal damage. Emotional stress has been implicated and observed as a trigger for the onset of disease and flares. Our comprehensive approach addresses these underlying imbalances through gut microbiome restoration, nervous system regulation, immune system modulation, and personalized anti-inflammatory protocols to achieve lasting remission and prevent disease progression.

What Exactly Is Crohn’s Disease?

Crohn’s disease is a chronic autoimmune inflammatory bowel disease (IBD) characterized by transmural inflammation that can affect any part of the gastrointestinal tract from mouth to anus, though it most commonly involves the terminal ileum and colon. Unlike ulcerative colitis, which affects only the colon’s inner lining, Crohn’s inflammation penetrates through all layers of the bowel wall, leading to complications such as strictures, fistulas, and abscesses in approximately half of patients within 20 years of diagnosis. The disease results from a complex interplay between genetic predisposition, environmental triggers, immune dysregulation, and profound alterations in the gut microbiome—including reduced diversity and abundance of beneficial bacteria like Faecalibacterium prausnitzii alongside overgrowth of pathogenic species. Crohn’s typically follows a relapsing-remitting course, with periods of active inflammation alternating with periods of remission.

Types of Crohn’s Disease

Crohn’s disease is classified based on the location of inflammation within the gastrointestinal tract, each presenting with distinct symptom patterns and treatment considerations.

TypeLocation AffectedCommon SymptomsConsiderations
IleocolitisTerminal ileum and colonDiarrhea, cramping in middle/lower right abdomen, significant weight lossMost common type affecting approximately 50% of patients; highest risk for strictures
IleitisTerminal ileum onlyDiarrhea, cramping, weight loss, fistulas/abscesses in lower right abdomenAffects approximately 30% of patients; risk of vitamin B12 deficiency
Crohn's Colitis (Granulomatous Colitis)Colon onlyRectal bleeding, diarrhea, skin lesions near anus, joint painAffects approximately 20% of patients; requires differentiation from ulcerative colitis
Gastroduodenal Crohn'sStomach and duodenumNausea, vomiting, loss of appetite, weight lossLess common; often undiagnosed; can cause bowel obstruction
JejunoileitisUpper small intestine (jejunum)Abdominal pain after eating, malnutrition, patchy inflammationMore common in children and adolescents; affects nutrient absorption

Why Crohn’s Disease Impacts More Than Digestive Health

Crohn’s disease extends far beyond the gastrointestinal tract due to its systemic inflammatory nature and the gut-immune connection. The chronic inflammation characteristic of Crohn’s triggers widespread immune responses that can affect joints (arthritis), skin (erythema nodosum, pyoderma gangrenosum), eyes (uveitis, iritis), liver (primary sclerosing cholangitis), and bones (osteoporosis). Transmural inflammation damages the intestinal barrier, allowing bacteria and toxins to enter systemic circulation and perpetuate inflammation throughout the body. Additionally, malabsorption from damaged intestinal tissue leads to nutritional deficiencies—particularly vitamin B12, iron, vitamin D, and calcium—contributing to anemia, fatigue, bone loss, and impaired immune function. The gut-brain axis dysfunction associated with Crohn’s also contributes to anxiety, depression, and cognitive difficulties commonly experienced by patients.

Diagnostic Options at Whole Gut Health

Comprehensive Crohn’s disease evaluation requires thorough assessment to determine disease location, severity, and underlying factors contributing to inflammation. At Whole Gut Health, we use advanced diagnostics to create personalized treatment protocols that address root causes alongside disease management.

Testing options may include:

Colonoscopy with Ileoscopy and Biopsy to visualize the colon and terminal ileum, assess disease extent, and obtain tissue samples for definitive diagnosis and differentiation from ulcerative colitis. Dr. Shustina is no longer performing colonoscopies. We will review any prior records of colonoscopies. If a colonoscopy is needed during your care. We will refer you to one of the carefully screened Gastroenterologists within our network who will perform the procedure on our behalf.

Small Bowel Imaging (MR Enterography or CT Enterography) to evaluate small bowel involvement, strictures, fistulas, and disease activity in areas not accessible by colonoscopy.

Applied Kinesiology or muscle testing to help delineate root causes and confirm precise customized treatment protocols

Comprehensive Stool Analysis with Microbiome Profiling to assess gut microbiome composition, identify dysbiotic patterns characteristic of Crohn’s, and measure inflammation markers including calprotectin and lactoferrin.

Inflammatory Markers and Serologic Testing including CRP, ESR, ASCA antibodies, and pANCA to help confirm diagnosis and monitor disease activity.

Nutritional and Micronutrient Assessment to identify deficiencies in vitamin B12, iron, vitamin D, zinc, and other nutrients commonly depleted in Crohn’s disease.

Short-Chain Fatty Acid Analysis to evaluate gut bacterial metabolism and butyrate production critical for intestinal healing.

SIBO Breath Testing since small intestinal bacterial overgrowth frequently coexists with Crohn’s disease and requires concurrent treatment.

We customize testing protocols based on symptom patterns, disease history, and suspected contributing factors to ensure comprehensive evaluation and optimal treatment planning.

Frequently Asked Questions

Common questions, answered

What is Crohn's disease?

+

Crohn's disease is a chronic autoimmune inflammatory bowel disease (IBD) that causes inflammation throughout the gastrointestinal tract, most commonly affecting the terminal ileum (end of small intestine) and colon. Unlike ulcerative colitis, Crohn's inflammation penetrates through all layers of the bowel wall and can occur in patches with healthy tissue in between (skip lesions). The disease results from complex interactions between genetics, immune dysfunction, environmental triggers, and gut microbiome imbalances.

What are the different types of Crohn's disease?

+

Ileocolitis (most common, ~50% of patients)

  • Affects terminal ileum and colon
  • Symptoms: diarrhea, cramping in middle/lower right abdomen, weight loss
  • Highest risk for stricture development

Ileitis (~30% of patients)

  • Affects terminal ileum only
  • Symptoms: diarrhea, cramping, fistulas/abscesses
  • Risk of vitamin B12 deficiency

Crohn's Colitis (~20% of patients)

  • Affects colon only
  • Symptoms: rectal bleeding, diarrhea, skin lesions, joint pain
  • Requires differentiation from ulcerative colitis

Gastroduodenal Crohn's

  • Affects stomach and duodenum
  • Symptoms: nausea, vomiting, loss of appetite
  • Can cause bowel obstruction

Jejunoileitis

  • Affects upper small intestine
  • Symptoms: abdominal pain after eating, malnutrition
  • More common in children

What are the common signs and symptoms of Crohn's disease?

+

Gastrointestinal: Chronic diarrhea (sometimes bloody), abdominal pain and cramping, urgency, nausea, reduced appetite, mouth sores

Systemic: Significant weight loss, chronic fatigue, fever during flares, night sweats, delayed growth in children

Complications: Strictures, fistulas, abscesses, perianal disease, nutritional deficiencies

Extraintestinal: Joint pain, skin conditions, eye inflammation, liver complications, kidney stones

How is Crohn's disease diagnosed?

+

Comprehensive evaluation includes multiple assessment approaches:

Colonoscopy with Ileoscopy and Biopsy

  • Visualizes colon and terminal ileum
  • Obtains tissue for definitive diagnosis

Small Bowel Imaging

  • MR or CT enterography for disease extent and complications

Applied Kinesiology

  • helps delineate root causes and confirms precise customized treatment protocols

Comprehensive Stool Analysis

  • Assesses microbiome composition and inflammation markers (calprotectin)

Nutritional Assessment

  • Identifies common deficiencies (B12, iron, vitamin D)

SIBO Breath Testing

  • Evaluates concurrent bacterial overgrowth

What does Crohn's disease treatment involve?

+

Our comprehensive three-phase Crohn's resolution protocol includes:

Phase 1: Assessment and Root-Cause Identification

  • Evaluation of disease location, severity, and pattern
  • Microbiome analysis for dysbiotic patterns
  • Assessment of dietary triggers, nutritional deficiencies, and contributing factors

Phase 2: Targeted Intervention

  • Visceral Manipulation t o help optimize motility as well as address the mind body connection.
  • Energy Medicine to address the body’s vibration, the mind-gut connection and to empower the body’s unique ability to heal itself.
  • Anti-inflammatory protocols using natural compounds.

Phase 3: Long-Term Remission and Prevention

  • Sustained microbiome balance protocols
  • Flare prevention and early intervention strategies
  • Nervous System Regulation through consistent practices and lifestyle changes
  • Ongoing immune modulation and monitoring
  • Quality of life optimization
  • Tapering of medical therapies is often possible in collaboration with patient goals

How does gut microbiome dysfunction contribute to Crohn's disease?

+

Research has established that Crohn's patients consistently show characteristic dysbiotic patterns including reduced diversity, decreased beneficial bacteria (especially Faecalibacterium prausnitzii and other butyrate producers), and overgrowth of inflammatory species (particularly Enterobacteriaceae and E. coli). This imbalance reduces short-chain fatty acid production needed for intestinal healing, compromises gut barrier function, and triggers abnormal immune responses perpetuating inflammation.

Can Crohn's disease go into remission?

+

Yes, with comprehensive treatment, many patients achieve and maintain remission for extended periods. The goal of modern Crohn's management is not just symptom control but mucosal healing, which significantly reduces complication risk and improves long-term outcomes. Our approach combines conventional therapies when needed with gut microbiome restoration, anti-inflammatory nutrition, nervous system regulation, and lifestyle modification to maximize remission duration and quality of life.

What makes your approach to Crohn's disease treatment different?

+

At Whole Gut Health, we take a comprehensive approach to Crohn's disease that addresses underlying factors alongside disease management:

  • Focus on true root causes of the disease
  • Nervous system regulation as an important part of healing the mind- gut connection
  • Gut microbiome restoration as an important therapeutic target
  • Integration of conventional gastroenterology with functional medicine approaches
  • Personalized dietary protocols based on individual triggers and tolerances
  • Comprehensive nutritional assessment and repletion
  • Emphasis on sustained remission and quality of life rather than just symptom suppression

Who provides Crohn's disease care at your practice?

+

Dr. Alexandra Shustina is a board-certified gastroenterologist and internist who serves as NYC's and Miami's premier gut health specialist. She has training in both conventional gastroenterology and functional gut health, with particular expertise in inflammatory bowel diseases and comprehensive gut microbiome restoration protocols.
