Also known as: Crohn's Disease (Regional Enteritis)
Crohn's disease is a chronic inflammatory bowel disease (IBD) that can affect any part of the digestive tract, from mouth to anus, causing inflammation that extends through the full thickness of the bowel wall.
Crohn's disease affects approximately 3 million people in Europe and 1.6 million in the United States. It most commonly presents in young adults but can occur at any age.
Unlike ulcerative colitis, Crohn's can affect any part of the GI tract and involves the full bowel wall thickness, leading to complications such as strictures, fistulas, and abscesses.
The disease results from dysregulated immune responses to gut bacteria in genetically susceptible individuals. Smoking is the strongest modifiable risk factor, doubling the risk of developing Crohn's.
People with Crohn's Disease often experience the following symptoms.
Persistent loose stools, sometimes bloody, lasting weeks or months during active disease.
Crampy pain, often in the right lower abdomen, which may mimic appendicitis.
Abnormal connections between the bowel and other structures (skin, bladder, other bowel loops), a hallmark of Crohn's.
Joint pain, skin rashes, eye inflammation, and liver problems occur in 25-30% of patients.
Certain factors may increase your likelihood of developing Crohn's Disease.
Common approaches to managing crohn's disease. Always consult a healthcare provider for personalized treatment.
Anti-TNF agents (infliximab, adalimumab), anti-integrins (vedolizumab), and IL-23 inhibitors (ustekinumab) target specific immune pathways.
Azathioprine and methotrexate maintain remission and reduce steroid dependence.
Short-term use for flare induction. Budesonide for ileal disease with fewer systemic side effects.
Up to 50% of patients require surgery within 10 years. Bowel-sparing approaches are preferred.
Colonoscopy with biopsies showing characteristic skip lesions and granulomas. MRI enterography for small bowel assessment. Blood tests and faecal calprotectin for monitoring.
See a doctor for persistent diarrhoea lasting over 4 weeks, bloody stools, unexplained weight loss, or severe abdominal pain. Seek emergency care for signs of bowel obstruction.
Steps that may help reduce the risk of developing or worsening crohn's disease.
Avoid smoking (strongest modifiable factor)
Medication adherence
Regular monitoring
Balanced nutrition
If left untreated or poorly managed, crohn's disease may lead to:
No. Crohn's is an inflammatory bowel disease with visible inflammation and tissue damage. IBS is a functional disorder without inflammation.
Not yet, but modern biologic therapies can achieve deep remission in many patients.
Diet does not cause Crohn's, but certain foods may worsen symptoms during flares. Nutritional therapy is important.
