Great question! Beyond the more commonly discussed ones, there are some lesser-talked-about comorbidities worth knowing about with PBC.
Here are some that don't get as much attention:
- Sjögren's disease — Affects between 40% and 65% of people with PBC, causing dry eyes and dry mouth by attacking moisture-producing glands

Great question! Beyond the more commonly discussed ones, there are some lesser-talked-about comorbidities worth knowing about with PBC.
Here are some that don't get as much attention:
- Sjögren's disease — Affects between 40% and 65% of people with PBC, causing dry eyes and dry mouth by attacking moisture-producing glands
- Autoimmune thyroid disease — Affects 10%–15% of people with PBC, often leading to hypothyroidism, which itself is a major cause of fatigue, brain fog, and muscle weakness
- Limited cutaneous scleroderma — Affects 5%–15% of people with PBC, causing skin thickening and tightening, and sometimes affecting internal organs
- CREST syndrome — A specific form of scleroderma involving calcium deposits, Raynaud's phenomenon, esophageal issues, and skin changes
- Raynaud's phenomenon — Affects blood flow to extremities, causing color changes in fingers and toes in response to cold or stress
- "Arthritis of PBC" — A lesser-known type of arthritis distinct from rheumatoid arthritis, involving joint pain and swelling in the arms and legs that comes and goes It's also worth noting that antinuclear antibodies (ANA) are present in up to 70% of PBC cases, which is part of why so many autoimmune comorbidities overlap.
Sometimes symptoms of these comorbid conditions — like dry eyes or dry mouth from Sjögren's — can actually appear *before* a PBC diagnosis is even made. So if any of these sound familiar, it's worth bringing up with your doctor to make sure everything is being monitored properly.

Crest Syndrome I am being checked for too. Apparently it overlaps with PBC :(
