Core Tip

Core Tip: Fatigue is one of the most common and challenging symptoms reported by adults with inflammatory bowel disease. We evaluated the association between fatigue and sociodemographic profile, depression, anxiety, stress, insomnia, iron deficiency, vitamin B1 and B12 deficiencies, thyroid function, anemia, leukocyte count, and sedentary lifestyle in patients with Crohn’s disease (CD). An association was found with the following variables: Sedentary lifestyle, shorter time since CD diagnosis, combination of depression, anxiety, stress and insomnia, total leukocyte and segmented neutrophil levels, and reduced lymphocyte-eosinophil-lymphocyte ratio. These data may contribute to improving decision-making in the management of fatigue in patients with CD.
