Yes, weight changes with PBC can go in both directions — it's not just about weight loss. While some people lose weight due to poor nutrient absorption and reduced appetite, others can gain weight too.
Fatigue is a big factor here. When exhaustion takes over, it can be harder to stay active and easier to reach for quick energy fixes like sugary foods or caffeine. A myPBCteam member shared that extreme fatigue led them to eat chocolate bars and drink lots of coffee just to get through the day, which contributed to unhealthy weight gain. Some things that can contribute to weight gain with PBC include:
- Fatigue making it harder to exercise or stay active
- Cravings for quick energy foods that are high in sugar or fat
- Reduced physical activity due to symptoms like bone or muscle pain
On the flip side, some people with PBC lose weight due to poor fat absorption, nausea, or loss of appetite — especially as the condition progresses.
It's worth mentioning any weight changes, whether gain or loss, to your doctor. They can check for nutritional deficiencies or other factors and may refer you to a dietitian for personalized guidance.
