Crohn’s disease is a chronic inflammatory bowel disease (IBD) that causes inflammation anywhere along the digestive tract, from the mouth to the anus. It most commonly affects the:
✔ Ileum (end of the small intestine)
✔ Colon (large intestine)
Common Symptoms
-
Abdominal pain (often lower right side)
-
Chronic diarrhea (sometimes bloody)
-
Unintentional weight loss
-
Fatigue & weakness
-
Low-grade fever
-
Loss of appetite
-
Mouth ulcers
Causes & Risk Factors
Genetic Factors
-
Family history of Crohn’s
-
Mutations in genes like NOD2/CARD15
Environmental Triggers
-
Smoking (biggest preventable risk)
-
High-fat, processed diets
-
Urban living
Immune System Dysfunction
-
Abnormal immune response to gut bacteria
Diagnosis
-
Blood tests (check for anemia & inflammation)
-
Stool tests (rule out infections)
-
Colonoscopy + biopsy (gold standard)
-
Imaging (CT/MRI enterography)
-
Capsule endoscopy (small intestine exam)
Treatment Options
Medications
-
Corticosteroids (short-term flare control)
-
Immunosuppressants (azathioprine, methotrexate)
-
Biologics (infliximab, adalimumab)
-
Antibiotics (for infections)
Surgery
-
Removal of severely damaged bowel sections
-
Fistula/abscess treatment
-
Strictureplasty (widening narrowed areas)
Lifestyle Management
-
Low-fiber diet during flares
-
Quit smoking
-
Stress reduction
-
Vitamin supplements (D & B12 often needed)
Potential Complications
⚠ Bowel obstructions
⚠ Fistulas (abnormal organ connections)
⚠ Malnutrition
⚠ Increased colon cancer risk
Living with Crohn’s
With proper management, patients can lead active lives. Key strategies:
✔ Regular GI specialist visits
✔ Trigger avoidance
✔ Balanced nutrition
✔ Gentle exercise
Emerging Research
-
New biologic therapies
-
