Crohn’s Disease and Other Autoimmune Diseases
People with Crohn’s often have other inflammatory or immune-related conditions. Knowing these links can help patients and clinicians watch for symptoms that might need evaluation or treatment.
Adults with Crohn’s or IBD, newly diagnosed patients, caregivers, and clinicians managing multisystem symptoms or screening for long-term risks.
What To Know
This Healthline article summarizes conditions that commonly occur alongside Crohn’s disease and other IBD, including inflammatory (autoimmune) disorders like rheumatoid arthritis, ankylosing spondylitis, psoriasis, and multiple sclerosis, as well as non-autoimmune but related conditions such as asthma, COPD, low bone density, anemia, and colorectal cancer.
It reviews possible shared causes (genetics, immune dysfunction, gut microbiome) and points out that having one autoimmune disease raises risk for others. The piece is an overview aimed at patients.
It does not present new research findings or treatment recommendations; rather, it lists associations reported in studies and clinical summaries and explains why symptoms might overlap or be confused with other illnesses.
If you have Crohn’s and new symptoms (for example joint pain, skin changes, neurological symptoms, severe headaches, or signs of anemia), it’s reasonable to mention these to your clinician so they can consider whether another condition might be present or whether tests are needed.
The article also highlights longer-term risks tied to colon involvement (increased colorectal cancer risk) and bone health concerns, which are already part of standard Crohn’s care considerations.
This is an explanatory patient-focused overview synthesizing associations reported in various studies and guidelines. It does not provide new trial data or detailed diagnostic criteria. Individual risk varies by disease location, severity, treatment, and personal medical history.
