Clear Liquid Diet for Post-Bariatric and Weight Loss Surgery Patients

The most important aspect of your clear liquid diet, immediately after bariatric surgery, is to keep well hydrated.​

Staying Hydrated

  • Sip liquids constantly. You should have 48–64 ounces (six to eight, 8-ounce cups) of fluids per day.
  • Dilute fruit juices. At first, you may need to dilute fruit juices to avoid nausea or diarrhea.
  • Avoid extremes. It may be helpful to avoid extremely hot or cold liquids until your stomach fully heals, usually around six weeks.

Remember, your stomach is still recovering from bariatric surgery. It's common to experience nausea or vomiting at this point. Please keep yourself hydrated.
