Core Tip

Core Tip: Fatigue is considered one of the most frequent and debilitating symptoms in primary biliary cholangitis, affecting over 50% of patients. The objective of this review is to outline current understanding regarding the pathophysiology of fatigue, the role of comorbidities and contributing factors, the main tools for fatigue assessment, the failed therapeutic options, and future treatment perspectives for this disabling symptom. Since fatigue is an extremely common and debilitating symptom and there is still no licensed therapy for fatigue in PBC patients, further research is warranted to understand its causative mechanisms and to find effective treatment.
