Crohn's Disease

Understanding Crohn's Disease

A chronic inflammatory bowel disease (IBD) that can affect any part of the digestive tract, most commonly the small intestine and colon.

It causes inflammation, which can lead to symptoms such as diarrhea, abdominal pain, fatigue, and weight loss.

The exact cause is unknown, but it is linked to genetics, an overactive immune response, and environmental factors.

Please consult a gastroenterologist for proper diagnosis and management of inflammatory bowel disease.

Diagnosis

• Blood tests: To check for anemia, inflammation markers (CRP, ESR), and nutritional deficiencies.
• Stool tests: To rule out infections and assess inflammation.
• Colonoscopy or endoscopy: Used to visually inspect the digestive tract and take biopsies.
• Imaging tests (CT scan, MRI, capsule endoscopy): To assess inflammation and complications.

Early diagnosis and treatment are crucial. Consult with a gastroenterologist if you have persistent digestive symptoms.

Comprehensive Treatment Options

Induction Therapy (Getting into Remission)

Corticosteroids - Fast-acting for acute flares

• Prednisone, budesonide
• Short-term use only (4-12 weeks)
• Effective but side effects limit long-term use

Biologics - Target specific inflammatory pathways

• Anti-TNF agents: Infliximab (Remicade), Adalimumab (Humira), Certolizumab (Cimzia)
• Anti-integrin: Vedolizumab (Entyvio), Natalizumab (Tysabri)
• Anti-IL12/23: Ustekinumab (Stelara)
• Anti-IL23: Risankizumab (Skyrizi), Mirikizumab (Omvoh)

Maintenance Therapy (Staying in Remission)

Immunomodulators - Suppress immune system long-term

• Azathioprine (Imuran), 6-Mercaptopurine (6-MP)
• Methotrexate
• Often used with biologics for enhanced effectiveness

JAK Inhibitors - Newer oral option

• Upadacitinib (Rinvoq) - recently FDA approved for Crohn's

Aminosalicylates - Limited role in Crohn's

• Sulfasalazine, mesalamine
• More effective in ulcerative colitis

Supportive Therapies

Antibiotics - For complications

• Metronidazole, ciprofloxacin
• Used for abscesses, fistulas, or pouchitis

Nutritional Support

• Iron, B12, vitamin D, folate supplementation
• Enteral nutrition for pediatric patients
• Exclusive enteral nutrition as induction therapy

Treatment plans are highly individualized. Work closely with your IBD specialist to determine the best approach for your specific situation.

Dietary Management

• Identify and avoid trigger foods (dairy, high-fiber, spicy foods, processed foods).
• Consider a low-residue or elemental diet during flare-ups.
• Nutritional supplements may be needed to prevent deficiencies.

Work with a registered dietitian experienced in IBD management for personalized dietary guidance.

Surgical Options

When Surgery is Needed:

• Bowel obstruction or strictures
• Fistulas or abscesses
• Perforation
• Severe bleeding
• Failed medical therapy with poor quality of life

Common Procedures:

• Strictureplasty - Widens narrowed areas without removing bowel
• Bowel resection - Removes diseased sections
• Fistula repair
• Abscess drainage

Important Notes:

• Surgery doesn't cure Crohn's - disease can recur
• 70-80% of patients eventually need surgery
• Minimally invasive laparoscopic approaches preferred when possible

Surgical decisions should be made in consultation with experienced IBD gastroenterologists and colorectal surgeons.

When to See a Gastroenterologist

• If you have persistent or worsening symptoms despite treatment.
• If you experience significant weight loss, fever, severe abdominal pain, or rectal bleeding.
• If complications like abscesses, fistulas, or strictures develop.

Long-Term Health Considerations

• Regular medical follow-ups to monitor disease progression.
• Increased risk of colon cancer—regular screenings may be needed.
• Higher risk of osteoporosis due to long-term steroid use.
• Mental health support—chronic illness can lead to anxiety and depression.

Maintain regular follow-up care with your IBD specialist for optimal long-term health management and cancer surveillance.
