Extraintestinal Manifestations of IBD

A gastroenterologist generally coordinates IBD care. Depending on the affected organ, patients may also need treatment from a rheumatologist, dermatologist, ophthalmologist, hepatologist, or haematologist.

Some EIMs, such as peripheral arthritis and erythema nodosum, may become more noticeable during active intestinal inflammation. However, conditions such as axial arthritis, uveitis, and primary sclerosing cholangitis may develop independently of intestinal disease activity.

Extraintestinal manifestations (EIMs) are health problems associated with inflammatory bowel disease that affect organs and tissues outside the digestive tract. They can involve multiple body systems, including the joints, skin, eyes, liver, bones, and vascular system.

EIMs can affect several organs and body systems, including:

- Joints: Arthritis and inflammatory back pain.

- Skin: Erythema nodosum and pyoderma gangrenosum.

- Eyes: Uveitis and episcleritis.

- Liver-related complications: Primary sclerosing cholangitis, which affects the bile ducts.

- Bones: Osteoporosis and reduced bone density.

- Blood vessels: Higher risk of developing blood clots.

The most common EIMs include joint inflammation (arthritis), skin conditions such as erythema nodosum, eye inflammation (uveitis and episcleritis), and liver or bile duct disorders such as primary sclerosing cholangitis (PSC).

Yes. Some extraintestinal manifestations, particularly joint pain, eye inflammation, and certain skin conditions, can appear before digestive symptoms and may be early signs of underlying IBD.

Yes. Both Crohn's disease and ulcerative colitis can cause extraintestinal manifestations. These complications may occur before, during, or after the onset of intestinal symptoms.

Not all EIMs can be prevented. However, maintaining good control of intestinal inflammation, following the prescribed treatment plan, attending regular medical check-ups, and reporting new symptoms early may help reduce complications and improve overall health.

Symptoms vary depending on the affected organ. Common symptoms include:

- Joint pain, swelling, and stiffness.

- Redness, swelling, or painful skin lesions.

- Eye redness, irritation, and blurred vision.

- Fatigue, weakness, and anaemia.

- Back pain and reduced bone density.

- Unexplained fever or inflammation.

Certain symptoms require prompt medical evaluation, including:

- Severe eye pain, redness, or sudden changes in vision.

- Sudden chest pain or difficulty breathing.

- Unusual swelling or discomfort affecting one leg.

- Severe or rapidly worsening skin ulcers.

- Persistent joint swelling or severe pain.

These symptoms may indicate serious complications, including uveitis, blood clots, or other inflammatory conditions.

Diagnosis depends on the affected organ and may involve:

- Blood tests, including complete blood count (CBC), CRP, and ESR.

- Liver function tests.

- Eye examinations by an ophthalmologist.

- Joint examinations and imaging tests.

- Skin examinations or biopsies when necessary.

Yes. Treatment depends on the type and severity of the manifestation. It may include controlling intestinal inflammation, anti-inflammatory medicines, immunosuppressive therapies, biologic medicines, nutritional support, and specialist care.

Yes. Some extraintestinal manifestations can persist or develop even when intestinal symptoms are under control. This is because inflammation outside the digestive tract does not always follow the same course as intestinal inflammation.

Yes. People with IBD have an increased risk of anaemia due to intestinal blood loss, iron deficiency, chronic inflammation, and poor absorption of nutrients such as vitamin B12 and folate. Common symptoms include fatigue, weakness, dizziness, and shortness of breath.

Yes. EIMs can cause chronic pain, fatigue, mobility problems, vision difficulties, and emotional distress. Early diagnosis, appropriate treatment, and coordinated care can help improve daily functioning and quality of life.
