Patients Whose Gallbladder Are Removed Are Recommended to Eat Less Oily Food. Why?

Patients whose gallbladder are removed are recommended to eat less oily food. Why?

The gallbladder stores bile which helps in the emulsification of lipids. In Absence of removal of bile, emulsification of fat would be insignificant/affected/less and hence fat absorption would be slow. Thus there are regular limits to such eating.
