Crohn's Disease
A chronic inflammatory bowel disease (IBD) that causes inflammation anywhere in the digestive tract, most commonly the end of the small intestine. Symptoms include abdominal pain, diarrhea, fatigue, and weight loss.

If you suspect you have crohn's disease, please consult a healthcare provider for proper evaluation and treatment.
Statistics & Prevalence
Crohn's disease affects approximately 780,000 Americans and millions worldwide. Along with [ulcerative colitis](/condition/ulcerative-colitis), it's one of the two main types of inflammatory bowel disease (IBD). Incidence is increasing, particularly in newly industrialized countries. It's most commonly diagnosed in people ages 15-35, but can occur at any age. Crohn's is slightly more common in women than men. Smoking doubles the risk and worsens the disease. There's a genetic component - 5-20% of patients have a family member with IBD.

Chronic lifelong condition with periods of remission and flares
Why Crohn's Disease Happens

- Blood in stool
- Fatigue
- Weight loss
- Reduced appetite

Quick Self-Care Tips
- 1Stop smoking - single most important thing you can do
- 2Take medications as prescribed even when feeling well
- 3Keep a food diary to identify trigger foods
- 4Eat smaller, more frequent meals during flares
- 5Stay hydrated, especially during diarrhea
- 6Consider a low-residue diet during flares (less fiber)
- 7Get screened for nutritional deficiencies (B12, iron, vitamin D)
- 8Manage stress - can trigger flares
- 9Get regular colonoscopies for cancer screening
- 10Find a gastroenterologist specializing in IBD

Home Remedies & Natural Solutions
Dietary Modifications
While there's no universal Crohn's diet, many find relief by avoiding trigger foods (often dairy, high-fiber, spicy, fatty foods). During flares, a low-residue diet may help. Some benefit from specific diets like SCD or Mediterranean diet. Work with a dietitian experienced in IBD.
Stress Management
Stress doesn't cause Crohn's but can trigger flares. Practice stress reduction through yoga, meditation, deep breathing, or counseling. [Anxiety](/condition/anxiety) and [depression](/condition/depression) are common with IBD - treating them helps overall health.
Probiotics
May help restore healthy gut bacteria balance. Evidence is mixed but some patients find benefit. VSL#3 and Saccharomyces boulardii have some research support. Discuss with your doctor before starting.
Turmeric/Curcumin
Has anti-inflammatory properties. Some small studies show benefit in IBD. Available as supplement or dietary spice. May help as adjunct therapy but not a replacement for medical treatment.
Omega-3 Fatty Acids
Found in fish oil, may have anti-inflammatory effects. Evidence is mixed but generally safe. Can be obtained from fatty fish (salmon, sardines) or supplements. High doses may cause GI upset.
Note: Home remedies may help relieve symptoms but are not substitutes for medical treatment. Consult a healthcare provider before trying any new remedy, especially if you have underlying health conditions.
FDA-Approved Medications
Important: The medications listed below are FDA-approved treatments. Always consult with a healthcare provider before starting any medication. This information is for educational purposes only.
Infliximab (Remicade)
Anti-TNF biologic given by IV infusion every 8 weeks. Very effective for moderate-severe Crohn's and fistulas. Often induces and maintains remission.
Warning: Increased infection risk (TB screening required). Infusion reactions. Rare lymphoma risk. Monitor for serious infections.
Adalimumab (Humira)
Anti-TNF biologic given by self-injection every 2 weeks. Similar effectiveness to infliximab. Convenient home administration.
Warning: Increased infection risk. Injection site reactions. TB screening required. Monitor for infections.
Ustekinumab (Stelara)
IL-12/23 blocker. IV induction then subcutaneous every 8 weeks. Good option when anti-TNF fails or isn't tolerated.
Warning: Infection risk (lower than anti-TNF). Injection site reactions. Generally well-tolerated.
Vedolizumab (Entyvio)
Gut-selective integrin blocker given by IV infusion. Targets the intestine specifically. Good safety profile.
Warning: Slower onset of action than anti-TNF. Infusion reactions possible. Infection risk lower than systemic biologics.
Lifestyle Changes
- ✓Quit smoking - absolutely essential for Crohn's management
- ✓Take all medications as prescribed even during remission
- ✓Identify and avoid your personal trigger foods
- ✓Eat smaller, more frequent meals during flares
- ✓Stay well hydrated, especially during diarrhea episodes
- ✓Get regular exercise - helps fatigue and mood
- ✓Manage stress through relaxation techniques
- ✓Get adequate sleep - [insomnia](/condition/insomnia) worsens symptoms
- ✓Take recommended supplements (iron, B12, vitamin D, calcium)
- ✓Get regular cancer screening colonoscopies
- ✓Maintain bone health (IBD increases osteoporosis risk)
- ✓Join a support group - chronic illness affects mental health
- ✓Plan for pregnancy with your doctor (many medications are safe)
When to See a Doctor
Consult a healthcare provider if you experience any of the following:
- Persistent diarrhea lasting more than a few weeks
- Blood in stool
- Unexplained weight loss
- Abdominal pain not relieved by bowel movements
- Fever without obvious cause
- New or worsening symptoms during treatment
- Signs of bowel obstruction (severe cramping, vomiting, no bowel movements)
- Severe abdominal pain (could indicate perforation or abscess)
- Signs of malnutrition
- Joint, skin, or eye problems
- Planning pregnancy (discuss medication safety)
Talk to a Healthcare Provider
If your symptoms are persistent, severe, or concerning, please consult with a qualified healthcare professional for proper evaluation and personalized advice.
Frequently Asked Questions about Crohn's Disease
Click on a question to see the answer.
Both are inflammatory bowel diseases (IBD) but differ in key ways. [Ulcerative colitis](/condition/ulcerative-colitis) affects only the colon and rectum with continuous inflammation limited to the inner lining. Crohn's can affect any part of the GI tract (mouth to anus), has patchy 'skip lesions,' and inflammation goes through the entire bowel wall. Crohn's can cause strictures and fistulas; UC typically doesn't. Some cases are hard to distinguish (indeterminate colitis).
There is a genetic component - you're more likely to develop Crohn's if a close family member has IBD. About 5-20% of patients have a first-degree relative with IBD. However, most people with Crohn's have no family history. Over 200 genetic variants contribute to IBD risk. Having the genes doesn't mean you'll definitely develop the disease - environmental factors also play a role.
About 70-80% of people with Crohn's eventually need surgery, but modern medications are reducing this. Surgery doesn't cure Crohn's but may be needed for complications like strictures, fistulas, abscesses, or medication failure. Common surgeries include removing diseased bowel segments or widening strictures. Many people do very well after surgery. The goal is to preserve as much bowel as possible.
Yes, many people with Crohn's live full, active lives. With proper treatment, many achieve long-term remission. You may need to make some lifestyle adjustments (diet, smoking cessation, medication compliance), but careers, relationships, travel, and having children are all possible. Connecting with support groups helps. Mental health support is important as chronic illness can be challenging.
