What should you know about Crohn's and psoriatic arthritis?

Crohn's disease affects the digestive tract. Psoriatic arthritis is an inflammatory joint condition associated with psoriasis, and it can affect joints, tendons, fingers, toes, or the spine. A person may have both conditions, or joint symptoms may be related to inflammation around the bowel rather than psoriatic arthritis. Joint pain, joint swelling, and morning joint stiffness can help describe the pattern, but they do not identify the cause by themselves.

Some medicines can influence both intestinal and joint inflammation, while others may suit one condition better than the other. Your gastroenterologist and rheumatologist may therefore need to share your history, examination findings, and medication plan.

Keep a simple record of bowel symptoms, skin changes, joint pain, swelling, stiffness, fatigue, and possible triggers. Note which joints are affected and whether movement eases stiffness. Bring the list to appointments, including every prescription, over-the-counter medicine, and supplement.

A clinician may assess your joints and digestive symptoms separately, then choose a treatment plan that considers both. Anti-inflammatory medication should be discussed before use because some options may irritate the digestive tract. Physiotherapy can support strength, joint movement, pacing, and safe activity alongside medical treatment.

Arrange medical review for a persistently swollen joint, new inflammatory-looking pain, worsening morning stiffness, or reduced ability to walk, grip, or use a limb. Seek urgent help for severe abdominal pain, repeated vomiting, heavy rectal bleeding, fever with a hot swollen joint, or sudden inability to bear weight. These symptoms need assessment rather than attribution to either condition.

Ask which symptoms suggest bowel-related inflammation, psoriatic arthritis, or another joint problem; whether your current medicines cover both conditions; which pain medicines are appropriate for your digestive history; and how to exercise during a flare.
