Discharge Instructions: Having a Clear Liquid Diet
Your healthcare provider has prescribed a clear liquid diet for you. This temporary diet is often prescribed right before surgery or medical tests when you need to have your stomach and intestines free of any food. This diet may also be prescribed after certain types of surgery or if solid food is not tolerated. The clear liquid diet is easy to digest and helps the body gradually get used to food again.
This diet is temporary. Do not follow this diet longer than directed. It doesn’t provide enough energy or protein for proper nutrition.
If you are on this diet for more than 5 days, you may need nutritional or vitamin supplements. Talk with your healthcare provider about this.
Keep track of what you eat and drink and how much while on this diet. Keep a log for your provider.
Choose these foods
The following foods are OK to have when you are on a clear liquid diet:
Fruit juices without pulp, such as filtered apple juice, grape juice, cranberry juice, and pulp-free lemonade
Fruit punch or fruit drinks with no pulp or pieces
Hot or cold coffee or tea (do not add milk or creamers of any type)
Sodas (lemon-lime soda, cola, ginger ale)
Clear soup (low-sodium and fat-free broth or bouillon)
Plain or flavored gelatin (don't add fruit or toppings)
Frozen juice bars made from clear juices (no fruit pieces).
Don't have these foods
Don't eat any food or drink not on the approved list above.
Ask your healthcare provider whether you should not have foods and drinks containing red or purple food coloring. They can leave residue that looks like blood on tests.
Follow up with your healthcare provider, or as advised.
When to call your healthcare provider

Fever of 100.4°F (38°C) or higher, or as directed by your healthcare provider
