ObjectivesMusculoskeletal pain has a considerable frequency in pediatric outpatients. Benign joint hypermobility (BJHS) and juvenile fibromyalgia syndrome (JFMS) are non-inflammatory causes of musculoskeletal pain. In these syndromes, pain is often accompanied by various symptoms such as fatigue, sleep difficulties, mood disorders, cognitive dysfunction, dizziness, headaches, abdominal pain, irritable bowel syndrome, and restless legs syndrome. Functional dyspepsia, functional vomiting, functional abdominal pain, functional constipation, and irritable bowel syndrome all together are termed functional gastrointestinal (GI) disorders. We aimed to evaluate the functional gastrointestinal disorders association of BJHS and JFMS.MethodsPatients aged 10-18 years who were diagnosed with functional GI disorder in the pediatric gastroenterology department were included in the study. The findings of BJHS and JFMS were evaluated by the pediatric rheumatology department. Scales for anxiety, somatization, and depression were administered by a child psychiatrist. COMPASS 31 scoring was used in autonomic dysfunction.ResultsThe prevalence of JFMS and BJHS was 64% and 32%, respectively in children with a functional GI disorder. Retrosternal chest pain, dysphagia, early satiation, nausea, vomiting, and regurgitation were common in JFMS (p = 0.007; p = 0.005; p = 0.018; p = 0.002, p = 0.013; p = 0.014, respectively). Gastrointestinal symptoms did not differ with BJHS. One hundred six (88.3%) and 99 (82.5%) had orthostatic intolerance and reflex syncope, respectively. One hundred three (85.6%) had anxiety symptoms, 101 (84.2%) had somatization symptoms, and 102 (85%) had depression symptoms.ConclusionsFunctional GI disorders, JFMS, and BJHS are complex intertwined disorders influenced by emotional distress. Therefore, a multidisciplinary approach is necessary for the diagnosis and treatment process.
