Colonoscopy is usually done under mild sedation and local anaesthesia.

The colon must be thoroughly cleansed before performing colonoscopy. Consequently, for two or more days before the procedure, considerable preparation is necessary to clear the colon of all stool. The patient is asked to refrain from eating any solid food for 24–48 hours before the test. Only clear liquid such as juices,

Red or purple juices should be avoided, since they can cause coloring of the colon that may be misinterpreted during the colonoscopy.

Alcohol, is a clear fluid, can theoretically be consumed the day before. But people seldom consume alcohol without taking solid food along with them.
