Is unexplained weight loss connected to PBC?
Yes, significant weight loss can absolutely be related to PBC, and your description of your body "starving itself" makes sense given how PBC affects digestion.
When PBC damages your bile ducts, bile can't flow properly from your liver to your digestive system. Bile contains acids that help break down fats and absorb nutrients from food. Without enough bile acids reaching your intestines, your body struggles to absorb the nutrients it needs, which can lead to malnutrition and weight loss.
Additionally, as PBC progresses, it can cause:
* Loss of appetite
* Nausea
* Difficulty absorbing fat-soluble vitamins (A, D, E, and K)
Advanced liver disease may also contribute to these symptoms, making it even harder to maintain a healthy weight.
This level of weight loss (over 4 stone) is significant and needs medical attention. Please talk to your doctor about this right away. They can run tests to check your nutritional status and bile acid levels, and may refer you to a registered dietitian who specializes in liver disease. They can help create a plan to ensure your body gets the nutrients it needs.
