How common is severe fatigue among patients with primary biliary cholangitis?
Fatigue is a common and often debilitating symptom in primary biliary cholangitis (PBC). A systematic review of 25 studies involving over 13,000 patients found that fatigue affects about 51% of PBC patients, and severe fatigue is reported in about 23% 1. Another large UK cohort study found that 60% of patients had significant fatigue, with severe fatigue being more common in those who also had cognitive symptoms 8. These numbers show that while fatigue is widespread, severe fatigue affects roughly one in four to one in five patients.
What the research says
A 2024 systematic review and meta-analysis of 25 studies (13,178 patients) found that fatigue is the most common symptom in PBC, affecting 51% of patients overall. Severe fatigue was reported in 23% of patients 1. The prevalence of severe fatigue was higher in studies from North America and Europe (26%) compared to Asia (8%), and in studies with a higher proportion of patients with cirrhosis (28% vs. 8%) 1. This suggests that severe fatigue may be linked to disease severity and geographic or genetic factors.
A separate UK-PBC cohort study of 2,002 patients found that 60% had significant fatigue (defined as exceeding a moderate symptom cutoff). Among those with significant fatigue, 55% also had significant cognitive symptoms, and this subgroup was younger and more likely to have severe fatigue 8. This highlights that fatigue in PBC often coexists with cognitive issues, which can worsen the overall impact on quality of life.
A 2025 review on personalized treatment for PBC notes that controlling fatigue is a key therapeutic target in symptom management 7. However, the same review acknowledges that no therapies have yet been proven to improve fatigue in clinical trials 8. The systematic review also found that only 36% of PBC patients with pruritus (itching) received treatment, suggesting that symptom management in general may be underaddressed 1.
What to ask your doctor
- Could my fatigue be related to PBC disease activity or other factors like sleep problems or depression?
- Are there any treatments or lifestyle changes that might help manage my fatigue?
- Should I be evaluated for cognitive symptoms that sometimes accompany fatigue in PBC?
- How can I track my fatigue severity to help monitor my condition over time?
- Are there clinical trials or new therapies being studied for fatigue in PBC?
