It's great to hear URSO is working so well for you! Your instinct about lipoprotein X is spot-on. People with PBC can have this unique form of cholesterol that doesn't behave like typical LDL or HDL — and importantly, it can throw off standard cholesterol test results, making cholesterol appear higher than it functionally is.

This is why doctors are encouraged to use a specific test called ApoB-100 for people with PBC rather than a standard cholesterol panel. It accounts for lipoprotein X and gives a much more accurate picture of your actual cardiovascular risk. Here's why cholesterol tends to rise with PBC in the first place:

- Damaged bile ducts reduce bile flow (cholestasis)
- Without proper bile flow, your body can't remove cholesterol efficiently
- Your liver may then compensate by *producing more* cholesterol
- The result is higher cholesterol in the blood — even with a great diet

So your healthy eating habits are absolutely worthwhile, but the rise in cholesterol may largely be driven by PBC itself rather than diet alone. Regarding statins — your concern is completely understandable. The good news is that if your ApoB-100 levels are low and you have no other cardiovascular risk factors (like high blood pressure, diabetes, or tobacco use), your doctor may simply monitor your cholesterol every few years rather than treat it aggressively.

If treatment ever becomes necessary, there are also alternatives to statins worth discussing with your hepatologist, such as PCSK9 inhibitors, which appear safe in people with moderate liver disease.

The most important step right now would be asking your doctor specifically about the ApoB-100 test — it could change the entire conversation about whether treatment is even needed.
