People always say "I'm tired too," and it's hard to explain our fatigue. How would the doctors suggest we explain PBC fatigue to others?
The symptoms of fatigue are about the same regardless of the cause.
The difference in PBC is that fatigue is not situational nor is it generally relieved by rest and sleep. Most people are tired from either lack of sleep, stress or situational or true depression. Once people are well rested, stress is relieved or depression resolved, fatigue improves.
This is not true in PBC as the source of fatigue is different. The fatigue is a result of the disease and is progressive. It tends not to get better. Only treatment of the disease will improve fatigue and currently, there are no good therapies which improve the fatigue associated with PBC.
