How long is the Liquid Phase?


What is the Liquid Diet?

Post-surgery, you’ll go straight into Phase 1 (the liquid diet). It lasts 2-4 weeks depending on your surgery type, and during this phase, you’ll consume only liquids with a goal of getting enough fluids and hydration to help with healing.

Why Do I Need to Do a Liquid Diet?

The most important reason for a liquid phase is to help you stay hydrated. Immediately after surgery, it’s common for patients to feel nauseous and experience vomiting. This can cause severe dehydration which can send you back to the hospital in severe cases.

Also, right after surgery the GI tract is healing and isn’t ready for rough or bulky foods. Liquids are gentle on your surgery site, you don’t want any pressure or stretching happening at this point post-op.

The Problem with Most Liquid Diets

Most liquid diets, especially clear liquid diets include recommended fluids like this:

  • Apple juice
  • Grape juice
  • Chicken broth
  • Decaffeinated coffee or tea

The problem is that none of these fluids have protein. Getting enough protein after bariatric surgery is important for wound healing and for feeling full, which is tough on a liquid diet.

Studies show that wound healing is much better when the patient consistently consumes enough protein.

Bari life’s answer is to utilize high-quality liquid protein supplements. This includes:

As well as other approved fluids like:

  • Sugar-free sports drinks

Liquid Phase Juice Rule:

  • If the juice has > 15g of carbs per 8 oz, dilute the juice with water 50% (½ water ½ juice)
  • If the juice has < 15g of carbs per 8 oz, do not dilute with water.
