Yes, stomach issues are actually quite common with PBC, and you're definitely not alone in experiencing them. PBC affects the bile ducts, which means less bile reaches the intestines — and bile is essential for breaking down fat. When fat isn't properly digested, it can lead to:

- Stomach cramps and pain
- Diarrhea

Yes, stomach issues are actually quite common with PBC, and you're definitely not alone in experiencing them. PBC affects the bile ducts, which means less bile reaches the intestines — and bile is essential for breaking down fat. When fat isn't properly digested, it can lead to:

- Stomach cramps and pain
- Diarrhea
- Nausea
- Bloating and gas
- Greasy stools As for gastric infections, PBC can lead to bacterial overgrowth in the small intestine. This happens because lower bile acid levels allow certain bacteria to multiply more than they should, disrupting the healthy balance in your gut. This can cause bloating, gas, diarrhea, and stomach pain.

A doctor can test for bacterial overgrowth with a simple breath test. To help support healthy gut bacteria, it may be worth trying:

- Fermented foods and yogurt
- A variety of plant-based foods
- Probiotic supplements (after checking with your doctor) It's also worth noting that some PBC medications, like ursodiol, can contribute to digestive discomfort. A myPBCteam member shared that switching to taking it at night helped reduce stomach issues. Always check with your doctor before making any changes to how you take your medication.
