Crohn's disease and UC: living with IBD

Two diseases, one family

Crohn's disease affects the entire digestive tract (from mouth to anus), in segments, with transmural inflammation. Ulcerative colitis (UC) affects only the colon and rectum, continuously. Evolves with relapses and remissions.

Symptoms

Chronic diarrhea (often bloody in UC), abdominal pain, weight loss, fatigue, fever, extra-intestinal manifestations (joints, skin, eyes).

Diagnosis

Colonoscopy with biopsies, intestinal MRI (Crohn's), fecal calprotectin (inflammation marker), biological assessment.

Treatments

  • 5-ASA (mesalamine): mild to moderate UC
  • Corticosteroids: flares, short-term
  • Immunosuppressants: azathioprine, methotrexate
  • Biotherapies: anti-TNF (infliximab, adalimumab), anti-integrins (vedolizumab), anti-IL-23 (ustekinumab, risankizumab)
  • Surgery: necessary in some cases (strictures, fistulas, medical failure)

Daily living

Absolute smoking cessation (Crohn's), nutritional monitoring, psychological support, up-to-date vaccinations before biotherapies.
