Post-operative care following a gastric sleeve surgery is extremely important for your recovery, especially when it comes to your diet. At Arch Bariatrics in St. Louis, we understand that adjusting to your new eating habits can be a challenge. Here’s what you need to know for a smooth transition and effective recovery.
Week 1 Post-Op: The Liquid Foundation
During gastric sleeve post-op diet week 1, you need to stick to a clear liquid diet. This helps prevent any complications such as dehydration, bowel obstructions, and gastric leaks. Your 1-week post op gastric sleeve diet can include:
- Water and ice chips
- Broth (beef, chicken, or vegetable)
- Sugar-free gelatin
- Decaffeinated tea or coffee
Make sure you avoid any drinks with sugar, caffeine, or carbonation in your 1-week post gastric sleeve diet so you don’t develop dumping syndrome.

- Sugar-free, non-fat yogurt
- Sugar-free protein shakes
- Broth-based soups that don’t have solid pieces
- Thinned oatmeal or cream of wheat
When picking what you can eat two weeks after a gastric sleeve, keep your intake smooth and free from solids to ease your stomach’s workload.

Week 3 Post-Op: Pureed Foods
When you get to the third week, incorporate pureed foods. You can have a bit more variety while still keeping everything gentle on your healing stomach. Here are some foods to puree:
- Soft fruits like bananas or avocados
- Cooked vegetables like carrots or squash
- Lean proteins such as fish or chicken
Make sure all of your foods are blended to a smooth consistency.
Week 4 Post-Op: Soft Foods
Going into week four, start adding soft foods that are easy to chew and digest. Pick options that are high-protein and low-fat:
- Scrambled eggs
- Soft fish
- Cottage cheese
- Cooked vegetables
This stage gets you ready for more regular eating.
Beyond Week 5: Transitioning to Solids
After the fifth week, start transitioning to more solid foods. Focus on fiber, lean proteins, vegetables, and low-fat dairy, and introduce new foods one at a time. Make sure to:
- Chew thoroughly to aid digestion.
- Continue to avoid sugary, fatty, and highly processed foods.
