Testing Resistant Potato Starch for Liver Disease Brain Complications

This is a small pilot study testing resistant potato starch, a dietary supplement made from potato starch, in people who have cirrhosis (advanced liver scarring) and hepatic encephalopathy (a condition where liver damage causes confusion, memory loss, and brain fog). The researchers want to understand how this supplement affects the helpful bacteria in your gut and whether it might help reduce these brain-related symptoms.

Hepatic encephalopathy is a serious and distressing complication of advanced liver disease that affects thinking and memory. Current treatments exist, but doctors are looking for additional options—especially food-based approaches—that might work alongside or enhance existing care by improving gut health.
