ClinConnect Summary

This clinical trial is looking at a new way to check how well the gallbladder contracts, or squeezes, using ultrasound, a painless imaging technique. The study will test how certain fatty acids taken by mouth affect the gallbladder’s ability to contract. This is important because the gallbladder helps with digestion by releasing bile, and problems with its function can cause discomfort or digestive issues.

People who might be able to join this study are adults who have a normal gallbladder and bile duct structure, as confirmed by ultrasound. However, anyone with a history of gallbladder or bile duct surgery, certain digestive diseases, infections, or other serious health problems would not be eligible. The study has not started recruiting yet, and it will include both men and women. If you join, you can expect to undergo ultrasound scans and take the fatty acids being studied, so researchers can observe any changes in gallbladder function. This study aims to find better ways to understand and possibly improve gallbladder health.
