Clear Liquid Diet
A clear liquid diet is just that, a diet consisting of foods and beverages made from liquids that you can see through. This type of diet is easily digested and leaves no residue in the gastrointestinal tract.
A clear liquid diet may be necessary when the gastrointestinal tract needs to be free of food or needs to rest, for instance:
- Before undergoing a test or procedure that involves the stomach or intestines
- After surgery, to start the transition back to regular food
- During flare-ups of certain digestive problems, such as diverticulitis
Although this diet allows for adequate hydration, it doesn’t provide enough calories and nutrients. Therefore, be sure your doctor is following you closely while you are on this diet. Also, do not stay on this diet for more than three days.
