- Drink different types of clear liquids. Don’t just drink water, black coffee, and tea.

For people with diabetes
If you have diabetes, ask the healthcare provider who manages your diabetes what you should do while you’re following a clear liquid diet.
- If you take insulin or another medication for diabetes, ask if you need to change the dose.
- Ask if you should drink sugar-free clear liquids.
Make sure to check your blood sugar level often while you’re following a clear liquid diet. If you have any questions, talk with your healthcare provider.
