When you think of Crohn’s disease, the gut naturally comes to mind. After all, Crohn’s is primarily known for causing chronic inflammation anywhere along the digestive tract. But what many people don’t realize is that this disease can also make its presence known far beyond the digestive system, impacting various other areas of the body. One surprising complication? Back pain.
- Inflammatory Bowel Disease (IBD), which includes Crohn’s disease and ulcerative colitis, affects an estimated 2.4 to 3.1 million people in the United States alone.
- Of those, between 25-40% experience symptoms outside of their intestines, a phenomenon called “extraintestinal manifestations” (EIMs).
- These EIMs can affect everything from the skin and liver to the joints, eyes, and kidneys.
- One of the most common and often overlooked EIMs is arthritis, which can lead to persistent back pain.
A painful pairing Arthritis and Crohn’s Disease
Surprisingly, arthritis affects nearly 30% of people with Crohn’s disease or ulcerative colitis, often causing inflammation in the joints of the spine, hips, and even large joints like the elbows and knees. What’s striking is that arthritis doesn’t just strike older individuals—it can affect younger patients too, adding to the challenges of living with IBD.
There are different types of arthritis linked to Crohn’s disease:
- Peripheral Arthritis: Typically impacts large joints such as the elbows, knees, and ankles.
- Axial Arthritis: Also called spondylitis or spondyloarthropathy, this type mainly affects the lower spine and sacroiliac joints at the base of the back.
- Ankylosing Spondylitis: A severe form of axial arthritis, this rare condition causes vertebrae in the spine to fuse, leading to reduced mobility and increased pain.
More than just a symptom
The type of back pain experienced by people with Crohn’s disease is often tied to axial arthritis, particularly in the lumbar spine (lower back) and sacroiliac joints (hips). This pain can range from mild to severe and tends to worsen during IBD flares. What makes it different from ordinary back pain? It often feels worse when resting and improves with activity, which is the opposite of typical back pain patterns.
People with Crohn’s may feel pain that:
- Comes and goes or persists constantly
- Intensifies during periods of inactivity
- Improves temporarily with movement or exercise
- Worsens during flare-ups when Crohn’s symptoms are active
Ankylosing spondylitis, the severe form of spinal arthritis, affects around 2-3% of people with IBD. Over time, it can cause the vertebrae to fuse, leading to a stiffened, hunched posture and decreased spinal mobility. While this is less common, its impact on a person’s quality of life can be profound.
Living with Crohn’s disease is more than just managing digestive symptoms. The ripple effects of the disease, particularly when it comes to the joints and back, can add layers of complexity to a person’s daily life. Fortunately, treating the underlying inflammation in the gut can often lead to improvements in extraintestinal symptoms like arthritis.
While treatment options exist to manage both the digestive and musculoskeletal symptoms of Crohn’s, awareness is key. If you or someone you know is living with Crohn’s disease and experiencing back pain or joint issues, it’s important to speak with a healthcare professional. Managing Crohn’s is a journey, but understanding the wide-ranging impacts of the disease can help individuals better advocate for their health and well-being.
By recognizing the signs of extraintestinal complications like arthritis and seeking timely treatment, experts say it’s possible to manage these symptoms and live a more comfortable, active life despite the challenges of Crohn’s disease.
