Backgrounds/Aims:
Musculoskeletal symptoms are common in patients with ulcerative colitis (UC), but no study has compared the prevalence of chronic pain to controls from a general population.
Methods:
Patients with UC (n = 1164) and controls (n = 3867) were sent questionnaires comprising demography, history of pain, pain localization and UC patients' Patient-Simple Clinical Colitis Activity Index. Chronic regional pain (ChRP) and chronic widespread pain (ChWP) were defined as having pain for at least 3 months.
Results:
The response rate for the patients with UC was 49.0% and for the control persons 61.7% (p < .001). The reported prevalence of ChRP and ChWP was higher in patients with UC versus controls (33.1% vs. 24.2%; p < .001 and 19.8% vs. 12.5%; p < .001). The patients with UC reported significantly more pain in the regions 'lower back', 'hip/upper leg' and 'lower leg/foot' compared to controls. The patients with P-SCCAI 5 (n = 121) reported more ChWP than patients with P-SCCAI <5 (n = 426) (46.3% vs. 12.7%; p < .001) and controls (n = 2425) (46.3 vs. 12.5%; p < .001) in all body regions. No significant difference in ChWP was found between patients with P-SCCAI <5 and controls (12.7% vs. 12.5%; p = .917).
Conclusions:
Patients with UC reported more chronic pain than controls from the general population, especially from the lower back and hip region. Higher UC disease activity was associated with more pain in all body regions.

Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...

Inflammatory bowel disease, or IBD, encompasses a group of disorders characterized by chronic inflammation or ulceration of the gastrointestinal tract.
Risk Factors
The exact cause of IBD remains unclear, although it is believed to be due to a mix of genetic, environmental, microbial, and immune factors. Genetic factors are significant in determining susceptibility to IBD, with family history being a critical risk factor. Individuals with a first-degree relative who has IBD are at...
01:30Inflammatory Bowel Disease II: Crohn's Disease
Inflammatory bowel disease, commonly known as IBD, refers to a collection of disorders that lead to persistent inflammation of the gastrointestinal tract. The two types of IBD are ulcerative colitis, which impacts the colon, and Crohn's disease, which can involve any part of the gastrointestinal segment.
Crohn's disease
Crohn's disease is a chronic, systemic inflammatory bowel disease (IBD) that predominantly affects the gastrointestinal tract. It is marked by...

Diagnostic studies
A colonoscopy is the definitive screening test, distinguishing ulcerative colitis from other colon diseases with similar symptoms. During a colonoscopy test, inflamed mucosa with exudate ulcerations can be observed, and biopsies are taken to determine the histologic characteristics of the...

Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
