What Is a Liquid Diet After Jaw Surgery?
If you are preparing for jaw surgery, you will need to understand the liquid diet phase. Here is everything you need to know.
A liquid diet means all your nutrition comes from liquids and purees β nothing that requires chewing. This phase typically lasts 2β4 weeks after orthognathic surgery.
- Why a liquid diet is necessary:
- Your jaw bones need to heal without movement
- Chewing would put stress on the healing bone and plates
- The incisions in your mouth need time to close
- Your bite is held in place by elastics
- What to include:
- Protein: Protein shakes, whey or plant-based protein powder blended with milk or water
- Dairy: Yogurt, kefir, milk, blended cottage cheese
- Fruits and vegetables: Blended smoothies, juices, strained soups
- Grains: Blended oatmeal, cream of wheat, thin porridge
- Fats: Avocado blended into smoothies, olive oil in soups
- Supplements: Ensure, Boost, or similar meal replacement drinks
- What to avoid:
- Anything with seeds or small particles that could get into incisions
- Straws (can dislodge blood clots and affect healing)
- Hot liquids (can increase swelling)
- Carbonated drinks (can cause discomfort)
- Alcohol (interferes with healing)
How to Make It Work
- Invest in a good blender
- Make smoothie packs in advance and freeze them
- Add protein powder to everything
- Eat 5β6 small meals per day rather than 3 large ones
