Potential Considerations

If you're lactose-intolerant, avoid regular dairy products during your liquid diet or take a lactase supplement before eating dairy to avoid undesirable gastrointestinal side effects.

Check with your doctor or a registered nutritionist to make sure your diet includes all the nutrients you need and that it won't interfere with any health conditions you may have, such as kidney disease, diabetes, heart disease or high blood pressure. You may need to take supplements, especially if you're on a liquid diet for more than five days.
